I have two routers at home. First router is upstairs and is connected to the cable modem. 2nd router is downstairs and acts as "signal booster" for the 1st router. Devices connected to the upstairs router have IP addresses of the form 192.168.1.n Devices connected to the upstairs router have IP addresses of the form 192.168.2.n. I blindly followed instructions from a website to do this set up, just glad it works!

Upstairs I have a PC running Win 7 64 bit. Its assigned IP is 192.168.1.7. I have a VNC viewer running on this.

Downstairs I have a 2nd PC running Vista 32 Home edition bit that is connected to the 2nd router and has IP Address 192.168.2.114. VNC server is running on this. It's listening on 5900. There is no firewall.

When I try to connect to this downstairs PC from upstairs it fails with message "Failed to connect to server". I cannot ping to this either.

If I try to connect to this downstairs PC using VNC Viewer from another computer that's connected to the same downstairs router then it works like a charm.

So what's the work around if the viewer is on a different "network"? I don't have any problems doing remote desktop connection from the downstairs PC to the upstairs PC even if they are connected to different routers.

Router information- Upstairs- ASUS RTN13U, downstairs- DD-WRT v24 RC-5

Thanks!

P.S. I posted this on the Ultra VNC forum as well but that doesn't seem to have a lot of activity, so taking the liberty to multipost.
