Hi all
(1) Pls I need someone to explain port forwarding i.e. forwarding a udp port to a specific host .Can Natting be used?
(2)Secondly what is SIP NAT traversal? What is the effect of turning it off?
(3)I have natting configured on my router if I issue the following command ,will it affect the preconfigured natting ?the commands are
no ip nat service sip tcp port 5060
no ip nat service sip udp port 5060
(4) I learnt that Some IOS versions will even crash on SIP behind NAT. See
http://lists.digium.com/pipermail/asterisk-users/2004-January/033718.html.
pls go through this link and pls advise .
(5) Which command can use in natting to forward
Forward UDP Port 5060-5082 to 192.168.1.4
Forward UDP Port 10000 to 20000 to 192.168.1.4
I use Cisco 1700 series router
I am using the above port for VoIP solution in asterisk .
