I would suggest using a Vyatta based server to Run Asterisk on or behind.. and use the load balance feature to forward your incoming connections to the Asterisk server this will create one default gateway for your asterisk server so you won't have to have two separate networks identified.. nor two NICs. or identify two ports on the server forwarding one of them to the original binding port of Asterisk.<br><br>if it wasn't for the Default gateway .. it would have been easy to do some port forwarding on the "internet router" side. but Asterisk needs to communicate with the internet to send packets back. <br>this is one of the scenarios i can think of. and can be done in 20 minutes. well it can be expensive if you calculate the costs of an additional computer on the network. :S<br><br><br><br>Tarek Sawah<br><br>Information Technology Adviser<br><br>Integrated Digital Systems<br><br>CCNP, MCSE, RHCE, TELECOM<br><br>USA: +1 386 492 9993<br><br><br><br><div><hr id="stopSpelling">From: chayn123@gmail.com<br>To: asterisk-users@lists.digium.com<br>Date: Sat, 17 Sep 2011 17:31:56 -0400<br>Subject: [asterisk-users] redundant traffic<br><br>
