Hi Rob,

Thanks again...unfortunately I can't monkey with the dynamic NAT that gives
my internal users access to the Internet or there will be alot of screaming.
I'm not sure if you got my last post or if I even get myself to be quite
honest ...let me attempt a diagram:

Vast Expanse of the
Internet-----------MyISPNextHop(a.b.27.1)------MyRouterExternalPort(a.b.27.2
)--------A whole bunch of magic(to
me)-------MyInternalVLAN(192.168.0.0/24)----Internal Users

so conversely my internal users go like:

192.168.0.x------->192.168.0.254(gateway)------->GlobalIPNo.1------>Internet

So where does the external interface come in?

My understanding with this model at least is that you need to have an
internal VLAN and the only way to NAT it to the outside IP is use an address
pool (in this case a pool of 1). So internally my users go through
192.168.0.254 as their gateway and are NATd to one of my assigned IPs using
a NAT pool.

I guess this is where my understanding of it all breaks down....they get to
my assigned IP but how does that get through to the external interface IP
which is hopped on to the ISP?

I think I am hopelessly lost on this whole thing.....I have to go now but I
will be back online in a few hours....

Thanks

Kevin

Hi Kevin,

Users hey!!!...
If you can, get some possible downtime redo the NAT statments.
This is only my suggestion and my understanding of it so hope it
helps...

-The internal network is overloading ie sharing the NAT pool of your
global ips.
/
ip nat pool INTERNET a.b.c.d a.b.c.d netmask 255.255.255.248
ip nat inside source list 7 pool INTERNET overload
access-list 7 remark SDM_ACL Category=16
access-list 7 permit 192.168.0.0 0.0.0.255 log
/
You'll most likely find that there is an overlap.
So!
-As it stands now (you have to excuse me coz its late here).
-You dont even need to use the extra global IPs but you can for many
other purposes.
-Your external interface is already a global IP which can be used to
perform PAT port address translation.
/
interface FastEthernet0
description $ETH-WAN$$FW_OUTSIDE$Internet
ip address a.b.c.d 255.255.255.252
/

-The NAT statement would have to be changed to PAT port address
translation.
-"ip nat inside source list 110 interface FastEthernet0 overload"
-"access-list 110 permit ip 192.168.0.0 0.0.0.255 any"
-The changes arent that severe as to disrupt the screaming its just a
case of a reload and putting the old info back in if it does'nt work.
-You might not even need some downtime when perhaps only a reload is
necessary if done correctly.
-You can use the other 5 global IPs for some other purpose but for
now...
-All thats happening now everyone on the internal network will be port
address translated to a single external IP ie the address of
FastEthernet0.
-Change the nat statement to replect the new external IP
"ip nat inside source static tcp 192.168.0.x 3389 Fastthernet_IP 3389
extendable"

This way I believe.. will narrow it down for you and maybe Im off the
beaten track but nevertheless its worth a shot...
Hope it makes sense.

Regards,

Rob

Good morning Rob,

Thanks for the reply again....I had a brief look last night but now that I'm
back at work its a little more clear..

So based on your last post....there is really nothing wrong with the way my
outbound overloading is setup, correct?

> ip nat pool INTERNET a.b.c.d a.b.c.d netmask 255.255.255.248
> ip nat inside source list 7 pool INTERNET overload
> access-list 7 remark SDM_ACL Category=16
> access-list 7 permit 192.168.0.0 0.0.0.255 log


The above is all already in my config.......the pool is only a pool of 1 of
my assigned IPs

So the real issue is in how I get the Terminal Services traffic in. That
being said you said:

> -The NAT statement would have to be changed to PAT port address
> translation.


What exactly would the statement below be replacing? I only have my overload
NAT statement for outbound Internet access and a NAT statement attempting to
allow 3389 traffic in? Is this a new NAT statement?

> -"ip nat inside source list 110 interface FastEthernet0 overload"
> -"access-list 110 permit ip 192.168.0.0 0.0.0.255 any"


Does this have to be Natted to the External Interface or can it be one of my
other assigned IPs (thus allowing me to add a DNS alias for my external
users).
Also is 110 a new ACL? Could this ACL be refined to only allow the internal
TS server (192.168.0.50)?

I think I'm kind fo starting to get things (maybe)! Am I even close?

Kevin

Hi Kevin!

This is what I believe is happening in respect of your NAT
translations.
Hope this makes more sense....as it was quite late last night so please
excuse me.
This is your NAT setup.
> ip nat pool INTERNET a.b.c.d a.b.c.d netmask 255.255.255.248
> ip nat inside source list 7 pool INTERNET overload
> access-list 7 remark SDM_ACL Category=16
> access-list 7 permit 192.168.0.0 0.0.0.255 log


According to the above:
-You have a NAT POOL called INTERNET associated with the external IPs.
-All clients ie (192.168.0.0 0.0.0.255) are translating to the NAT POOL
(INTERNET) hence the keyword "overload"
Your static statement for TS is being overlapped because of the NAT
statements above.
Make sense?
What you have is dynamic-NAT translation and PAT together.....
I think the quick solution would be to just PAT your existing external
IP as below:
//
ip nat inside source list 110 interface FastEthernet0 overload
access-list 110 permit ip 192.168.0.0 0.0.0.255 any
//

You will have to create this ACL 110 to bind to the PAT statement.
//
ip nat inside source list 110 interface FastEthernet0 overload
access-list 110 permit ip 192.168.0.0 0.0.0.255 any
//
All this is doing is translating any device on the 192.168.0.0 network
to the external fastethernet IP address.
This will replace the NAT POOL that you have assigned currently and use
the existing external IP of interface FastEthternet0 for all your
translations.

I am fairly certain that if you do this you will get your access to TS
but you will have to remove the existing NAT statements.
Touch Wood....only kidding!
Copy the current config to tftp so you have a backup..
Then the translation for TS:
//
ip nat inside source static tcp 192.168.0.50 3389 fastethernet_ip 3389
extendable
//
This way you simplify the config and make it more scalable.
Remember you can always put back the original statements if it does'nt
work.
Once you are certain that translations are happening correctly and
everyone is browsing away happily(no screaming) then you could start to
use the global IPs for your own purposes on subinterfaces or as
secondary ip addresses.

Please tell me if you think this is silly I might not be explaining
this clearly but thats just how I would approach it.

Regards,

Rob

Thanks so much Rob it makes much more sense to me now. But of course I still
have some questions .

I now understand what you meant my replacing my NAT that uses the NAT
pool....and replace it with NAT using the External Interface. My only
concern being what the ISP would have to say about that.

As for my Terminals Services NAT, if I use the External Interface IP I would
not be able to use one of my IPs to create a DNS alias.....aka
myterminalservices.mycompany.com.....which would be nice but not
essential.....the external TS users would just end up using the interface
IP. I guess the question becomes why do I have these IPs if I end up doing
everything through the IP of the router interface? I know they can be used
in conjunction with the additional ports on the back of the router for DMZ
etc.

So for further clarification here (I must seem quite obtuse) any request to
one of my IPs is directed (via DNS from my ISP) to the router's external
interface IP?

I think I will experiment with your suggestion.....what about security
inbound.....this change shouldn't effect anything since the inbound rules
apply to the interface itself correct?

Man you must be sick of me!

Thanks again (broken record)

Kevin

Kevin,

No worries at all just glad to have helped if at all!....
If you have a domain name you could get your domain hosts to setup a
record of your choice for TS using the external IP address however you
will still have to put the port number(if you change the default) at
the end of the domain name when you run TSclient ie
-"ts.mycompanyname.comortnumber"

In respect of security its all still the same, as the access-lists do
their stuff before NAT takes place anyway.
Obviously there is only one level of authentication concerning TS being
the login screen so if you have to stick to TS change the listening
port on the server or just map a high external port number to the
internal(3389) port.

All I can say concerning the ISP is give PAT a go(sounds dodgy) and see
if you can browse the web from inside and connect to the terminal
server from the outside.

You will find use for the other IPs that you have and it would have
been better if you could assign one of those global IPs to your
external interface instead of the current one.
That you would have to check with your ISP though.
Subnet the current block to a 255.255.255.252 mask effectively
splitting it up into 2 networks with 2 IP addresses each giving you 4
usable IP addresses as opposed to the 6 you currently have, thus giving
you more flexibilty in respect of DMZs and security.

Hope this has helped and good luck....
Keep me posted.

Rob

Hi Rob,

I was successful switching to the new NAT using the FE0 address rather than
the pool....no screaming...yayyy!!

However....I added the TS forwarding on 3389 and it still can't get
through.....now keep in mind that I have the SDM and have been using the Web
based tools to watch things....

List 101 is still dropping my attempts.....I can see the IP of the
residential ADSL setup I am using to simulate an external request. ACL 101
is denying requests on 3389. Now we never did get into the ACL 101 inbound
and how it deals with incoming 3389 requests....however I have considered it
and attempted a few things.

My understanding is that any request is processed by the inbound ACL 101
before any translation or other action is take, therefore it would seem as
though the only thing preventing access is this the ACL...I have tried
adding a rule to the top of the ACL 101:

permit tcp any host External_IP eq 3389 log

This seems to make the most sense to me but it still seems to drop 3389
requests..

The part that really burns me is that the residential ADSL sits behind a
D-link retail router and I can open up 3389 to the host and it works like
that.....but I also realize security is not nearly as strong on that router.

Here is the running config as it stands now minus the sensitive stuff and

Kevin,

Excellent!
Just looking at your NAT statement and it doesnt reflect the changes...
//
"ip nat inside source static tcp 192.168.0.50 3389 (fastethernet0_ip)
3389 extendable"
//
Thats your PAT interface(fastethernet0), every host initiating
connections whether inbound or outbound are port address translated
with that IP(fastethernet0) instead of 1-to-1 translations or
6-to-many.

Also the ACL 101 must reflect that IP where global IPs where used.
Are you able to log on to the router via console or telnet maybe setup
syslog and see what IP address is getting hit on the logs.

If you want... again for testing put an entry at the beginning of ACL
101:
//
"access-list 101 permit tcp any any eq 3389 log"
"access-list 101 permit tcp any host 192.168.0.50 eq 3389 log"
"access-list 101 permit tcp any host (fastethernet_ip) eq 3389 log"
//
If you are able to view the logs you will see which one is passing
access so to speak.
Let me know how you get on.

Rob

Was this not the way to get 3389 through?
I guess I got lost on this again so....

ip nat inside source list 110 a.b.c.2 overload

in combination with...

access-list 110 permit tcp 192.168.0.0 0.0.0.255 any

gets my users out to the net correct? I guess it must since its working

and

ip nat inside source static tcp 192.168.0.50 3389 a.b.c.2 3389 extendable

is the NAT required to get requests to my server

and

As for this did you mean to add all 3 at once and see what gets past what?

I am pretty much using the SDM web interface exclusively as I am pretty new
to the command line....I have logging and firewall status that I can view
but all I can see is that my attempts are denied by ACL 101....even if I
have all 3 above...or should I try each one at a time to see if any of the 3
will let my requests through?

Thanks again and if you get sick of banging your head against the wall
please tell me and I can always harras someone else

HI Kevin,

No dont worry I am not banging my head against the wall at all I am
happy to help unless you feel that I am sending you on a wild goose
chase....but thats not the case.

I just wanted to confirm that (a.b.c.2) is your FastEthernet0 IP
address.
Also that in your ACL 101 that (a.b.c.2) is your FastEthernet0 IP
address.
As long as ACL 101 has the FastEthernet0 IP address then we can
definitely mode on to the ACL.

What I mentioned previously about the ACL:

> //
> "access-list 101 permit tcp any any eq 3389 log"
> "access-list 101 permit tcp any host 192.168.0.50 eq 3389 log"
> "access-list 101 permit tcp any host (fastethernet_ip) eq 3389 log"
> //


If you could add those lines to the ACL 101 at the top.
You do already have the last line.
The reason for this is to see which line will actually allow TS traffic
through.

On the logs that you are viewing does it actually give you any
information on whats being hit ie destination IP address/source IP
address etc.
Feel free to email me if you prefer and I can happily talk you through
logging in via console to get better debugging against the access-list
and see whats getting hit.

Sorry for not being clear but heres me email:
roboravec TA hotmail TOD com
