Due to unintentional behavior breakage in the newest versions of GUPnP and GSSDP, the UPnP NAT traversal in all VoIP applications that use Farsight2 is currently broken. This includes Empathy, Pidgin, aMSN, etc. I advise distributors to just stay with the older GUPnP 0.16 (and GSSDP 0.10) releases until this is sorted out. For those who care, the details are on bugzilla.
Update: I’ve released GUPnP-IGD 0.2.1 that works around these problems.
