I have the same model linksys router. Had a real problem with lost udp switch to tcp, till I set up a port trigger .
To setup port triggering open up your browser and type
http://192.168.1.1/Filters.htm into the "Address Bar".
You will be prompted for a username and password.
By default there is no username, and the password is admin. once you type in the password click OK
Once you've gotten past the log in you should be at the filters tab.
Click on the Forwarding tab
Once the "Forwarding" section opens, click the Port Triggering button.
Once you've done this, a new window will appear. Here is an example of how to fill out the ports:
Application NameTrigger Port RangeIncoming Port Range
CUSeeMe7648 ~ 76487648 ~ 7648
CUSeeMe1503 ~ 15031503 ~ 1503
CUSeeMe24032 ~ 2403224032 ~ 24032
Once you've done this hit Apply, then Continue.
After the settings have been applied, port triggering is successfully setup!
I set mine to 2000 to 4000
