1 Exchange Server with 2 gateways
Posted on 2006-07-18
I have one Exhcange 2003 server with 2 NICS. Each NIC has IP configured with gateways to separate internet connections. Each internet connection has a NAT firewall with port 25 forwarding to the Exchange server. The public IP of each Internet connection has an mx record for the domain that Exchange is picking up email for.
Under "advanced properties" within "network connections", the NIC with the connection to the intenet gateway with the primary mx record is top of the list for "connections" under the "adapters and bindings" list. Exchange can send and receive mail from this gateway no problem.
Is there any way of getting Exchange to at least pick up mail coming in on the 2nd NIC? Or do I need a separate Exchange server for each gateway? Or can I get away with using a load-balancing router with just 1 Exchange server?
