NAT of traffic from duplicate paths

Unanswered Question
Jan 14th, 2008

Hi Folks,

I have this network:


| |


In this case net1 and 2 are equal cost paths and thus packets can go via either. If I am SRC IP NAT'ing on RTR2 on the way to the internet. Will the traffic arrive correctly on the web server? The question is really, how will RTR2 treat the same traffic arriving on two different NAT inside interfaces. Will it see the traffic as the same traffic or will it NAT them into different outside flows?



I have this problem too.

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.
