I suspect AK's MTAs have smtp routes to the server's public IP. IIRC they can set up multiple SMTP routes to the customer and they'll be treated in a round-robin fashion (at least smart MTAs should do this). So with 2 static NATs set up on the router (one for each public IP) this would be a breeze. Assuming failover between the two links is automagically handled by the router then outgoing mail should work OK as well with a caveat; if he's relaying out through AK they need to allow outbound relaying from his JTL IP. Still not enough details though to complete the picture... Regards, Steve
