[asterisk-users] SER+iptables+Asterisk

[Siqhamo Sifo]

I have ser sitting on my iptables nat box  and my asterisk box on the lan .
Ser does forwarding so that any requests (register,invite,ack,...) to the
nat box at 5060 r sent to my asterisk box on the  lan .I can register from
outside
to my asterisk box but there is only one way audio , reason being that
when the asterisk box send a sip packet whith session description the sdp
part of the sip packet is not natted .
