[f-nsp] [ServerIronXL] accessing VIP from real server

[news.gmane.org]

Hello

I am having an issue with a load balancer config whereby the real 
servers (smtp servers) cannot access the VIP that they are part of.

The servers are able to ping the VIP but any connections to port 25 are 
timed out.

The load balancer is running ip forwarding, with the VIP range and real 
server range on the same VE.

Enabling "server source-nat" resolves this , but makes all the 
connections on the servers appear to come from the load balancer alone.

I need the real servers to be able to contact the VIP without 
translation taking place.

Does anyone know a solution to this problem ?

Thanks
