I've got the Netgear FVS336g dual WAN router with Comcast Business Internet on one port and Bell South DSL on the other in load balancing mode.
I had it working with a firewall rule for each to forward port 3389 to my terminal server at 192.168.0.5, but with double NAT on each, but the router was hanging every 24 hours or so.
I now have both services set up in "Bridge mode" but now I can only access the TS via the Comcast connection.
I have verified that port 3389 is open on the DSL line, and if I change the firewall rule for the DSL line to forward to a different computer, i.e, 192.168.0.24, it connects up to that computer just fine.
I just can't get it to connect to the TS. The idea is to have the DSL line as a backup to connect to the TS.
