[asterisk-users] Port Forwarding SIP rtp

[Evalyn Wafula]

If you are using a Linux gateway to connect your local LAN to the Internet,
then redirect as follows:

 
/sbin/iptables -t nat -A PREROUTING -p udp -i ethx --destination-port 5060 \
     -j DNAT --to-destination xxx.xxx.xxx.xxx

 

/sbin/iptables -t nat -A PREROUTING -p udp -i ethx --destination-port \

10000:20000 -j DNAT --to-destination xxx.xxx.xxx.xxx

 

Where ethx is Internet facing interface of the Linux gateway and
xxx.xxx.xxx.xxx is the IP address of Asterisk.

I need help with SIP,RTP port forwarding , I can connect using SIP and

make calls but there is no audio even though my kernel has sip support and

I suspect that it has to do with iptables.
