Is it possible to do a Source NAT on a Cisco ASA Firewall?

[boodox]

Hi All,

I'm looking for some advise on NAT. I've got a requirement to do a Source NAT from an internal address to an external address on a Cisco ASA firewall. Hopefully the flow below explains

Source-->Firewall*-->Switch-->Router-->Router-->Destination
(*Source NAT)

I know you can do Source NAT on Nokias but I'm struggling to find a way of doing it on a Cisco ASA. First of all,

* Is it possible? From what I've read, it's not.
* If not, is there a workaround by which I can do the NAT on the switch or the router on the other side of the firewall?

I'd REALLY appreciate any advise.

Thanks in advance

Please help me understand your definition of Source NAT. Soruce NAT in some circles is actually a high availability feature and in some it is simply just NAT/masquerading.

Hi unclerico,

My mistake. I needed to do a destination NAT and NOT a source NAT to a single address so apologies for misleading.

As it turns out, the requirement for a single destination NAT wasn't possible because it was causing load-balancing problems for the third party who we were trying to connect to.

We ended up doing normal one-to-one NAT's (which is what I'd originally wanted) and it works fine.

Thanks for the offer of help and apologies again for any confusion.

Thanks
