I have a client that has a T1 connection with a Netgear firewall and a DSL connection with a Motorolla modem/firewall device. I would like to be able to RDC to the SBS 2003 server over both the T1 and the DSL connection.
T1 Router LAN IP: 192.168.0.254
DSL Router LAN IP: 192.168.0.253
SBS 2003 LAN IP: 192.168.0.248
Scenario and constraints: The SBS currently has only one NIC and IP Address. (I can add a second IP address if that would help me achieve the resolution I'm seeking). I prefer not to add a second NIC. I need for the server to send mail out of the T1 router (.254) only. In the SBS's TCP/IP properties I have added a second gateway for the DSL (.253).
My progress: By adjusting the 'metric' setting for each gateway I can direct Internet browsing traffic thru whichever Internet connection I want, however, I can only connect via RDC with the T1 and not the DSL, or, I can connect via RDC with the DSL and not the T1. I have not tried using the "Automatic" metric setting for both of the gateways though... my concern is that if I did, how would I control which gateway the server would send mail through.
This is my first question to be posted so I hope I've setup the question with enough info for you to reply. If not, please let me konw.
