ASA 5512 Nat control

ahmed_hafez20011 — Tue, 12 Mar 2019 07:03:11 GMT

I have ASA 5512 with version 9.4(ASDM version 7.4).

ASA is connected to load balancer (Ascenlink).

I read than we can disable nat control after version 8.3.i looked inside configuration and ASDM, i didn't found no nat control.how can i do that.

I want to do that because i have another nat on ascenlink(load balancer) and i think it's not logical to make two nat on 2 devices connected to each other , in addition there are DSL modems (connected to load balancer) and this is a third nat on them.

Thank you....

First make sure the load

First make sure the load balancer has a route for the network behind the ASA via the interface that the load balancer plugs into (probably the outside interface).

Look for lines with "nat" in them for the servers concerned. You'll be able to remove those. The load balancer will need to reference the IP addresses on the actual servers themselves.

i have just finished reading

i have just finished reading about Nat, so my question was NAT EXEMPTION.

(in version 8.3) i found when you specify the real source and destination as the same translated source and destination, that means no nat rule applied. bypass without nat.

(in version 8.2) the equivalent is nat 0 with access list. means no nat applied.

sorry my question wasn't specific.

Thanks Mr.P.dath
