Problem with nat and port forwarding with Cisco 877W

Hi!!
I have just finished my personal configuration, everything works
pretty, but the nat does not forward any port... so that emule or voip
doesn't work.
Can you check my config and tell me what is wrong? I have a Cisco 877W
with IOS 12-24.15T6.

My config:

Thanks ;-)

 

Problema in parte risolto:
dal log del firewall vedevo che i pacchetti eran bloccati dalla
"Access-list 101" che contiene un po' di regole per bloccare/abilitare
il traffico abilitato a entrare nel router da internet (varie regole
anti spoofing).
E avendo questa config:

interface Dialer0
ip access-group 101 in

che risponde a questa lista di accessi:

access-list 101 deny ip 127.0.0.0 0.255.255.255 any
access-list 101 deny ip 169.254.0.0 0.0.255.255 any
access-list 101 deny ip 172.16.0.0 0.15.255.255 any
access-list 101 deny ip 192.0.2.0 0.0.0.255 any
access-list 101 permit tcp host 63.208.196.96 eq www any log
access-list 101 permit udp host 207.46.232.42 eq ntp any
access-list 101 permit udp host 192.43.244.18 eq ntp any
access-list 101 remark Traffico abilitato ad entrare nel router da

access-list 101 deny ip 10.0.0.0 0.255.255.255 any
access-list 101 deny ip 192.168.0.0 0.0.255.255 any
access-list 101 deny ip 198.18.0.0 0.1.255.255 any
access-list 101 deny ip 224.0.0.0 0.15.255.255 any
access-list 101 deny ip any host 255.255.255.255
access-list 101 permit udp host 195.186.1.111 eq domain any
access-list 101 permit gre any any
access-list 101 deny icmp any any echo
access-list 101 deny ip any any log
access-list 101 permit udp host 195.186.4.111 eq domain any


il traffico internet veniva impedito e non dirottato nella giusta
porta, mentre se elimino la riga
ip access-group 101 in
allora tutto funziona perfettamente.

ma allora cosa devo mettere fra le regole della access-list 101 per
permettere al traffico internet di esser forwardato sulla giusta porta
del giusto ip senza che sia bloccato e senza rinunciare alle regole
anti-spoofing?

 

ip nat inside source static tcp 192.168.1.3 5900 interface Dialer0
5900

Presumably this is to facilitate VNC inbound to 192.168.1.3.


You will need to also allow this traffic in
access-list 101 otherwise it will not work.

Secondly - as answer you have not asked for
Unless you are *hosting* a dns server you do not need

access-list 101 permit udp host 195.186.1.111 eq domain any

interface Dialer0
ip inspect Firewall out

The Inspect operation will allow the traffic to
return without the explicit ACL.

ip inspect name Firewall dns


Also -
access-list 101 deny ip any any log
access-list 101 permit udp host 195.186.4.111 eq domain any

The latter will never be checked.

 

I don't know if emule is a voip service that uses h323 but inspecting
h323 traffic may be an issue

If it is h323 based service then consider checking if their are
adjustable timeout settings in the Firewall IOS inspection of h323.

"ip inspect name Firewall h323"
You are inspecting h323 traffic with firewall IOS per command above.

Regards

 

I don't know if emule is a voip service that uses h323 but inspecting

Ho, emule is a p2p program, not a voip service. Anyway I don't have any
h323 inspecting.

 

You will need to also allow this traffic in

I have tried to add a rule in access-list 101 that traffic with lines
like this:

"access-list 101 permit tcp any host 192.168.0.3 eq 5900"

and so I've done for each other port I have to open to internet traffic
inbound.

but it doesn't work. The only way to get internet traffic to pass to
the right port of the right device is to disable at all the access-list
101 by doing this:
"interface Dialer0
no ip access-group 101 in"

but this way I lost all basic protections!

this ip is not on my lan, it is an internet public dns.

Anyway, thanks for the tips ;-)

 

Do you know that the access list is processed sequentially?

That is, if the "deny ip any any" is *before* some permit
statement then the permit statement is ignored.

Obviously.

You are allowing it *inbound* from the internet.

My point is that if your DNS access requirement is for
a DNS clients inside to use the DNS server
195.186.1.111 then the "Inspect" feature will
permit the replies to come in. You do not need to create
explicit entries in the inbound access-list.

The Inspect feature temporarily opens access for
response traffic in replies to requests.

In summary my suggestions are probably correct.
This is my day job.

 

bod43 ha usato la sua tastiera per scrivere :

Sorry, it was my bad brain that misundestands everything this night!
I got an important lesson! Thanks I'm new to IOS so I'm still
learning...

Go to bed now, bye!

 

Sorry for that - bit irritated tonight.

if you are adding the ACL entries with
access-list 101 ......

then the new lines go at the bottom
(after the deny ip any any).

You need to delete the ACL and re-add the whole thing.

no access-l 101
.....
.....

Alternatively there is a more recent editor.

sh ip access-list 101
- displays with line numbers
conf t
ip access-l extended 101

no 10 ! remove line 10

15 permit .........

Add new line between 10 and 20.

If in doubt re-test and post config again.
Also sh ip access-list might be useful.

If you expand your logging buffer you will be able to see
logged access-list packets.

sh log

Ok, the problem is always here.

**********************************

I have done this:

*****************************
interface Dialer0
no ip inspect Firewall out
*****************************

but as you can see I always have the line "ip inspect Firewall out"
(please, dont' laugh!!) Anyway it seems that dns requests still pass.
These are my ip inspect name Firewall:

Normal traffic still pass (eg: firefox can show websites), but applications that require port forwarding don't work.

*************************************


and the last thing:
I have a line in access-list 101 that is not accepted:
access-list 101 permit udp any host 192.168.0.3 eq discard
but it must be
access-list 101 permit udp any host 192.168.0.3 eq 9
that is for WakeOnLan function!!!

Ok, that's all

 

The solution could be this:
in ACL I have to specify theip internet address, and not my eth
address.
so the line:
access-list 101 permit tcp any host 192.168.0.3 eq 4711
become
access-list 101 permit tcp any any eq 4711
and this way the nat port-forwarding shoul function also with access
list.
