[SR-Users] Trouble when bridging call between UDP and TCP clients behind NAT

Hi All, I'm try to setup kamilio v4.0.2 under a Fedora18 64bits having a public address in order to bridge calls between UDP and TCP clients. Everything works pretty fine between UDP clients even if behind NAT. But as soon as one TCP client is being called I'm getting this below on kamailio side. Note that the port is wrong and the TCP client doesn't get aliased nor tcp port remappend or received field is set: Call-ID: 23306738-94b3-49b5-b7e8-dc1b8a8061db CSeq: 50696 REGISTER User-Agent: PJSUA
