We're using Sonicwall 2040 for our firewall.  A vendor needs access to a pc with gotomypc.  we established connection, but he can't see the screen, only the chat portion of gotomypc.  They think our firewall is blocking it. Do I need to open a port on the firewall to allow this?  I don't see anything in the logs to indicate that the firewall is blocking traffic for this activity.

Are you outbound filtering on the firewall?  Most of thsese services just require Port 443 (SSL) and Port 80 (Web) traffic to be aloud outbound and no port forwards.  I would say if you aren't egress filtering at that site that it's most likely a problem with the installation of gotomypc and not the firewall blocking it.

He's right, there should be any firewall issues, especially if you're not seeing anything in the log.  See here for more information:

No, go to my pc doesnt need anykind of firewall holes.   We have multiple running behind massive firewalls and they work fine.   Gotta hand it to citrix for that.  

I say its a problem with go to my pc, if not then its some kind of spyware or something interferring with it.  

Perhaps your resolution is set too high or too low for his monitor?   I haven't ran into that situation yet but they can be different resolutions.

Uninstall GoToMyPC on the workstation and then reinstall it from the manual installer location at their sign-in page.  We use WebEx and sometimes have the same issue.

The other option would be if your computer is not configured to allow ActiveX controls to run.  Try using a different browser (Firefox preferably) or try using the Java client.

Is your Web Access through an HTTP Proxy?  We send our outbound web traffic through the HTTP Prozy on our non-Sonicwall firewall and specific content types or HTTP methods are filtered out, causing problems for applications such as gotomypc.  Try setting up a boggo standard port 80 rule for that specific machine to see if that helps
