Re: Disabling NAT

access-list extended NoNAT permit 192.168.1.0 255.255.255.0 10.10.10.0 255.255.255.0

nat (inside) 0 access-list NoNAT

This would disable NAT for traffic sourcing from 192.168.10/24 going to 10.10.10.0/24. The key is the 0 after (inside).

It's much easier to enable/disable NAT via CLI.

Here's a link that might help as well. http://cisco.com/en/US/tech/tk648/tk361/technologies_white_paper09186a0080091cb9.shtml

HTH and please rate.

Re: Disabling NAT

I need the procedure to do it on ASDM and reducing lines on FWSM. Could any one explain on this?

Re: Disabling NAT

What version of software are you running on the FWSM? I believe on version 3.1 you can disable nat control where you do not have to configure nat.
