[Users] outgoing proxy through VPN ?

[raviprakash sunkara]

Hello  gray,


Use ngrep or sipsak , that U should download and configure , tthis is for
communcation tracinf for  "SIP".

If U want to trace the  traffic communicatios,  in default  of Linux system
there is called " Ethereal" or
Check its in " /usrsbin/ethereal"

I think Urs problem is the ports are not forwording , and there are diable
in route or gateway or firewall.

Bye
