Hi,
I have a problem using SER, i have a client behind CheckPoint FW, when
the client tries to register, SER receives the SIP REGISTER message and
SER reply to the source IP and source PORT, but because the client is
behind CheckPoint FW if the source port is not 5060 the FW blocks it, so
i need SER to reply not to the source port of the client but to port 5060.
i'll attach ngrep on the SER server:
client sends REGISTER to the SER server at 192.168.0.161:5060.

but i need to response to port 5060 and not the source port , i'm not
using rport, i also talk to CheckPoint service and they claim that they
are working according RFC 3261, and that my SER server should reply to
port 5060
any suggestions?
Thanks In Advance,
David Lubarski,
