multiple outside NAT's to the same internal IP

I believe the answer to this is no but wanted to verify.

Can I have multiple NATs off the same interface to one internal IP?

For example.

static (inside,outside) a.a.a.2 10.20.30.248 netmask 255.255.255.255

static (inside,outside) a.a.a.3 10.20.30.248 netmask 255.255.255.255


Where the subnet  and IP block is also the same on for the two external NATs.

Hi,

So you are trying to do the following:

translate the ip 10.20.30.248 to a.a.a.2

and

translate the ip 10.20.30.248 to a.a.a.3.

i.e. translate the internal ip to two external ip addresses. If yes, then this is not possible.

Hope this helps.

Anisha

Hi,

This should be possible in ASA 8.3.

Check this doc for an idea about NAT configuration in 8.3.
