I want to put a ASTERISK BOX bend a Firewall. So I have given below rules.
iptables -A FORWARD -p udp -d 192.168.101.30 -m multiport --dports 3478,4569,5060 -m state --state NEW -j ACCEPT
iptables -A FORWARD -p udp -d 192.168.101.30 --dport 10000:20000 -m state --state NEW -j ACCEPT
iptables -t nat -A PREROUTING -p udp -i eth0 -d 1.2.3.4 -m multiport --dports 3478,4569,5060 -j DNAT --to-destination
192.168.101.30
iptables -t nat -A PREROUTING -p udp -i eth0 -d 1.2.3.4 --dport 10000:20000 -j DNAT --to-destination 192.168.101.30
pls assume 1.2.3.4 is the ip that connects to the internet.
I use Xlite sotphone to talk. I can register. it says user ready. I can dial extentions as well. But , WHEN I talk , Both parties can not hear anyrhing.
in rtp.conf file, PORT 10000 to 20000 are also available.
Hope to hear from you.
