NAT: forward two public ports to the same private server?

We've got an 1812 configured to do load balancing between two separate ISPs. We've got a number of servers behind the 1812 and need to be able to forward traffic from both ISPs to those servers.

Basically, I'm trying to forward ISP1:3306 and ISP2:3306 to the same SERVER:3306.

I tried just throwing in two static NAT entries...

ip nat inside source static tcp 192.168.1.99 3306 interface FastEthernet0 3306

ip nat inside source static tcp 192.168.1.99 3306 interface FastEthernet1 3306

...but that doesn't seem to work.

Anyone have any suggestions?

Re: NAT: forward two public ports to the same private server?

In some complex cases, NAT can be used for multihoming, which may achieve a certain degree of loadbalancing. However, it is the function of the routing protocol used that achieves the loadbalancing, not NAT.
