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:
