I am using the S60 5th Edition SDK. It seems as the NAT traversal techniques have been removed (STUN, TURN, ICE, etc). However it seems that they will be included in Symbian^3, since the source code for Symbian^3 seems to include NAT traversal.
My question: Is it possible to backport the NAT traversal functionality from Symbian^3 to S60 5th Edition?
Any other ideas on how to get NAT traversal functionality into S60 5th Edition?
