[Freeswitch-users] Registration from behind NAT doesn't work

Hi Im having problem on registering some sip devices that are behind NAT and dont support STUN. Please have a look at: ftp://v2.vrs.pl/pub/test.pcap Freeswitch replies to public IP which means it knows its NATed device, but why not to port that request comes from ? I found that this can be forced by <variable name="sip-force-contact" value="NDLB-tls-connectile-dysfunction"/> I have added this line to extension file under <variables> section, but it brings no results. Im new to freeswitch so if you need some action from my side, thread me as newbie. Kind regards, -- Adam Obuchowski
