Configuration of IPtables-can't register sip trunk

[scenarist]

I am little bit confused about simple configuration of iptables i.e I have successfully setup iptables firewall but still I can not to register sip trunk. When I delete this rule "iptables -A INPUT -s 0/0 -j drop " then I can register successfully sip trunk. This is mu etc/sysconfig/iptables

Code: Select all
