static NAT to two ISPs

On an ASA, I can do the following:

static (inside,isp1) 10.10.1.10 192.168.8.10 netmask 255.255.255.255

static (inside,isp2) 10.11.1.10 192.168.8.10 netmask 255.255.255.255

This allows the ASA to respond to traffic on either public interface, on behalf of the private interface, albeit with a return path specified by the routing table.

How can I do the same thing on a 2811 router?

If I try to enter two NAT statements using different public IPs, but the same private IP, the 2nd one overwrites the 1st.

Any help would be most appreciated.

Re: static NAT to two ISPs

Just use two different route-maps within the static NAT and this should do the trick.

Re: static NAT to two ISPs

Ahh, that makes sense. I was wondering why I couldn't specify the interface if I entered an IP, but I can specify the interface using a route-map. I will try this.

Thank you !
