CISCO ASA 5510 Configs...
I've got a Cisco ASA 5510 I am currently trying to configure NAT on....I really cannot find configurations in the ASDM and was just trying it out and now am trying to use command line. My problem is I don't understand the newer version of the command line and am having problems enabling NAT this way.
I know previously I would have done so easily
config t
int e 0/0
ip address
no shu
ip nat outside

Anyways, this seems to not be the way now? Anyone have any ideas here because I just am wasting my time searching on the subject. Tired of using ? in command line!!!!

external int add:
internal int. add:

do you want to enable nat for a particular IP or what??

What I am having problems with is enabling NAT on the border router. The outside address on the interface is the 10 dot address and the inside address of the interface is a 172 dot interface.

you have to use the command like

nat inside x local_int_IP broadcast_IP


nat(inside, outside) public_IP private_IP

i used this way in 5520ASA

Did you mean the subnet mask on the first line you responded back with?

nat inside x local_int_IP broadcast_IP

I'm not able to get back to the NAT work until Tuesday but now looking over what your saying, I think I understand the first part....Also, your just in global config mode while configuring, right?

kPradeep_venkata 11-14-2008 03:34 PM

yes.. u have to do in the config mode

I put in NAT (inside, outside) and get following:

ERROR: % Invalid input detected at '^' marker.

The ^ marker is just starting at the "i" on the inside within the parenthesis....Am I supposed to be placing something within the parenthesis rather than "inside" and "outside"? I'm getting really frustrated with this, usually if I forget a command I can easily use the ? and find what I need.... when i do NAT ? within the config it just bounces back a message that makes no sense....Feeling rather stupid right now not being able to do this basic config!!!!

these are the two ways i use to do on asa 5520

nat (inside) 3 - this is if any any global pool of public IP address defined

static (inside,outside) Public_IP netmask - this is to nat an private IP with Public IP explicitly

this is same procedure on asa 5510 also
