nat 0 Problem

I give two nat 0 commands in a pix.

nat(inside) 0 access-list inside_nat(name of the access-list)

nat(inside) 0 access-list 100 (access-list no)

when i give `show nat` command ,it shows only one nat 0 statement.This means pix is not takeing two nat 0 commands .It replaces one with the other.

Could any body help me out as to how configure two `nat 0 <access_list>` commands in a pix.

Thanks and regards for the fast responce.

Re: nat 0 Problem


This is normal, you cannot add two nat statement with the same ID.

To bypass this, you have to merge your two access-list into only one. And then reference it in the NAT 0 statement.

Be carefull that the access list are not used for other purpose into your config.

If you do need to keep 2 separate access-lists, then use 2 different NAT ID's, like:

nat(inside) 0............

nat(inside) 1...............

Just make sure you match up your global statement accordingly

Yes, this is a way to create two different NAT entries.

But, the purpose of the NAT 0 is to allow address to be not translated.

This is not the purpose of the NAT 1 (or other).
