[Freeswitch-users] Asterisk's nat=yes feature

Hi, I have a scenario where my softphone is behind nat and freeswitch is not behind nat. With asterisk I could make the audio work with nat=yes in the user's configuration. What is the settings for this on freeswitch? I have tried everything from the following pages: http://wiki.freeswitch.org/wiki/Natted_Softphone_ATA http://wiki.freeswitch.org/wiki/NAT http://wiki.freeswitch.org/wiki/NAT_Traversal http://wiki.freeswitch.org/wiki/General_NAT_example_scenarios (btw these are linking back to each other) Is it not that just easy as net=yes in asterisk? Many thanks, Zoltan
