I have remote Windows 2003 server with two network interfaces e.g. Cn1 and Cn2. I need that all traffic goes through Cn1 except for one port (for me it's 3389, rdp for administration) that works over Cn2. Currently when I setup all connections work through Cn1, I completely lose connection over Cn2 - and can't connect to server via RDP over Cn2. Now I used static routing based on my ip address (which can changed - so it's bad).
