If that is the case, then the MAC address would<br />not change.<br /><br />I think that what is going on here is that you have a IP address<br />conflict/overlap the two networks.<br /><br />Let's take a standard out-of-the-box config. Most routers plant the internal<br />addresses on the 192.168.1.x network. If both the DSL router and the VOIP<br />router are doing this, then you have the following kind of problem:<br /><br />DSL Line (Public IP's) --> DSL Modem (192.168.1.0/32 or 192.168.1.1) --> VOIP<br />Router (192.168.1.0/32 or 192.168.1.1) --> Internal network (192.168.1.0/24).<br /><br />Notice that both routers think that their address is 192.168.1.1. When the VOIP<br />router gets traffic that it does not know what to do with, it is supposed to<br />hand it off to it's default gateway, which is the DSL modem. But since it has<br />the same IP address as the modem, it cannot find a route to it, and therefore a<br />routing loop is created.<br /><br />Given this, most verizon routers can be setup in Bridged mode, thereby the VOIP<br />router can be given the public IP address for its WAN port and the problem is<br />likely solved.<br /><br />HTH,<br /><br />Kyle<br /></p><p>Kyle, first, before I begin, thank you for stopping by yesterday. I apologize for the server kicking you off but I did a code upgrade yesterday and one this morning so things are back the way they should be.</p><p>Second, you are correct. At one time I had a router installed on my own network, but I had it set up in<br />Cable modem -> Router -> VoIP & Hub fashion. Since my wireless router quit working, I now have everything<br />set up as cable modem -> VoIP unit -> 1gbit switch and it works like a charm as you saw when you logged into my Citadel server yesterday :) Gotta love port forwarding :)</p><p>--<br />Robert Wolfe, Linux/Windows Admin<br />Net261.com / OpenSource Solutions<br />robert@net261.com - http://www.net261.com:2000</p></blockquote>
