Netgear FVS336G dual wan router won't connect to Terminal server from both ports

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,  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,, 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.

Any suggestions?

It's working now---it seems like there is some flakiness in this router though.  Hopefully, when the new firmware is released (it's due to be released this week)  it will resolve this.

I power-cycled the entire system - modems, router, etc - and then I could connect on both ports.  I'm fairly certain I restarted everything when I made the bridge mode changes, but I was making other changes as well, so who knows.

But here's the weird part.  After the power-cycle, only the TS could access the internet, and I could RDP to the TS on both ports from outside.  Doubly weird is that the TS is a virtual server running on a bridged network adapter, and the host system couldn't access the internet while the TS could.

I rebooted the router again from the diagnostics tab, and then the internet came up on all computers, and I can still RDP in on both ports to the server. So right now it is good.

The true test will be to see if the router connections stay up -- the whole reason I made the changes is that I was losing connectivity after about 24 hours.
