Remote printing using Remote Desktop over VPN
application which I want to use remotely. We have a VPN set up via the broadband modem/router there, accessed through the native Windows support (Vista business). The local printer (Sharp) is on the network at 192.168.1.50. I can ping that from my local machine. When connected to the remote XP box, I can run the application but I can't see or ping the printer - even though I can "see" the "Fax printer" on my local machine. I can't ping my local printer. Using netstat on the remote XP box I could see that there was a connection on port 3389 via 10.0.0.220 (which can only be the termination of the VPN there). When I tried tracert I found it trying to go out through the Default Gateway and unable to reach the printer or my local PC at 192.168.1.101. Of course I'd love to be able to print locally from the remote machine - what would I have to do? I mused over the "route add" command-line utility, wondering if that might do the trick, but I've no way of being sure that the VPN will always terminate at the same IP address (10.0.0.220) and I'd be getting into some cumbersome scripting to detect it locally (although I don't rule that out). I bet this is a common problem - hopeful for some smart advice!

All the outgoing traffic from the XP machine had been going through the remote machine. Phil Show quote

Thanks! It is a multi-function printer, so I won't change the port type. Either way, I'd have thought there should be a way to access a device on the local subnet from the remote session over a VPN??

Thanks for the patient explanation! Phil I think that you are using the wrong approach here.
The port 3389 connection is your remote desktop connection to the remote computer. You should be using the settings in remote desktop to print to a local machine rather than a remote one.

I'm not clear why you think my approach is wrong (but I'm more than happy to entertain the possibility!). I did configure the RDC settings to make the local printer(s) available during a remote session, but only the local Fax-printer is there. As the required printer is a stand-alone network device, I'd have thought I should be able to see it through the VPN and so print to it. However, I can't ping back to it from the remote session, and was wondering if creating an explicit "route" might achieve this. Of course, if there's a way of having RDC do this for me by tweaking the printer or the RDC settings that would be a better option. Phil  |
