ASA 5510 Two static NAT for same inside ip

Router outside ASA has connections to two providers and I am given a subnet of 16 IPs from each.

If I try to configure a second static NAT on the ASA with a different real ip but same inside ip I get 'duplicate NAT etc..' Any ideas ? I need to configure the two NATs so that I can 'see' the inside server through two diffrerent ISPs.

Thanks a lot.

Re: ASA 5510 Two static NAT for same inside ip

Hi,

I'm not familiar with ASA. I was just wondering how would the ASA cope with 2 public IP addresses on 1 interface.

Hi,

This should be feasible if you are trying port translation.

i.e one service on the internal server can be accessed via ISP1 IP and another service via ISP2 IP.

Suppose 1.1.1.1 belongs to ISP1 and 2.2.2.2 to ISP2

static (inside,outside) tcp 1.1.1.1 25 10.1.1.1 25 netmask 255.255.255.255

static (inside,outside) tcp 2.2.2.2 23 10.1.1.1 23 netmask 255.255.255.255

HTH

Shijo George.
