Hi,
My implement is quite simple:
[sip 7960] --------- (internal) [Kamikaze + asterisk1.4.9] (external) ------ X-Lite.
2 sip devices can call each other, just no audio going thru. If I register X-Lite on the internal network, no problem at all. Is this a problem with NAT & RTP? the file /etc/firewall.user is like this:
#!/bin/sh

iptables -F input_rule
iptables -F output_rule
iptables -F forwarding_rule
iptables -t nat -F prerouting_rule
iptables -t nat -F postrouting_rule
The following chains are for traffic directed at the IP of the
WAN interface
iptables -F input_wan
iptables -F forwarding_wan
iptables -t nat -F prerouting_wan
Open port to WAN
– This allows port 22 to be answered by (dropbear on) the router
iptables -t nat -A prerouting_wan -p tcp --dport 22 -j ACCEPT
iptables -A input_wan -p tcp --dport 22 -j ACCEPT
– for SIP server
iptables -t nat -A prerouting_wan -p tcp --dport 5060 -j ACCEPT
iptables -A input_wan -p tcp --dport 5060 -j ACCEPT
iptables -t nat -A prerouting_wan -p udp --dport 5060 -j ACCEPT
iptables -A input_wan -p udp --dport 5060 -j ACCEPT
Port forwarding
– This forwards port 8080 on the WAN to port 80 on 192.168.1.2
iptables -t nat -A prerouting_wan -p tcp --dport 8080 -j DNAT --to 192.168.1.2:80
iptables -A forwarding_wan -p tcp --dport 80 -d 192.168.1.2 -j ACCEPT
DMZ
– Connections to ports not handled above will be forwarded to 192.168.1.2
iptables -t nat -A prerouting_wan -j DNAT --to 192.168.1.2
iptables -A forwarding_wan -d 192.168.1.2 -j ACCEPT
Please advise, thanks.
