[Asterisk-Users] Debuging SIP

[Ian Pattison]

Are you using IPTables? Here's my IPTables config for SIP and RTP... you need to open UDP ports 5060 and 10000-20000

$IPTABLES -A FORWARD -i $EXTIF -o $INTIF -p udp -m udp --sport 5060 --dport 5060 -j ACCEPT
$IPTABLES -A FORWARD -i $EXTIF -o $INTIF -p udp -m udp --sport 10000:20000 --dport 10000:20000 -j ACCEPT
$IPTABLES -A FORWARD -i $INTIF -o $EXTIF -p udp -m udp --sport 5060 --dport 5060 -j ACCEPT
$IPTABLES -A FORWARD -i $INTIF -o $EXTIF -p udp -m udp --sport 10000:20000 --dport 10000:20000 -j ACCEPT
$IPTABLES -t nat -A PREROUTING -i $EXTIF -p udp -m udp -s EXTERNAL_SIP_SOURCE --dport 5060 -j DNAT --to-destination ASTERISK_SERVER
$IPTABLES -t nat -A PREROUTING -i $EXTIF -p udp -m udp -s EXTERNAL_SIP_SOURCE --dport 10000:20000 -j DNAT --to-destination ASTERISK_SERVER

Hope this helps,

Ian

Guys.

Im having NAT problems. Any good tips on how to debug remote SIPS, how to
see which ports are been sent and received, etc?
