[Freeswitch-users] NDLB-connectile-dysfunction does not work

Hello, I have tried to add <variable name="sip-force-contact" value="NDLB-connectile-dysfunction"/> to the user according to the Wiki page about NAT traversal, but it is not working as expected. I see the answer to the registration request going to the correct (Ethernet) IP address, but the port is wrong. It still uses the port from within the SIP packet, instead of the Ethernet port. I have tried also to add at the same time <param name="NDLB-force-rport" value="true"/> without success I am using XML curl for the directory and I confirmed that both settings are in the xml. Is there any other additional setting missing? Thank you
