Westell 6110F modem breaks pidgin connectivity

[LailaKumaki at gmail.com]

I recently reconfigured my network using a new Westell 6110F modem as a  
bridge to my original router.

Without changing my router's settings whatsoever, the new modem appears to  
have made pidgin unable to connect to my IM protocols. gmail and MSN get a  
refused connection.

However, accessing gmail through my browser and accessing MSN through the  
live messenger work perfectly.

I have attempted forwarding the protocol's listen ports on my router to no  
avail. Pidgin now simply fails to connect. Curiously I attempted to use  
Trillian as an alternative and encountered the same problem.
