[nflug] Router Questions

[Joshua Ronne Altemoos]

this was not an issue with my vonage router since linksys typically is
defaulted to 192.168.15.1

	Actually, I think he said that he never had the DSL router not be
the first
	device facing the DSL network. If that is the case, then the MAC
address would
	not change.
	
	I think that what is going on here is that you have a IP address
	conflict/overlap the two networks.
	
	Let's take a standard out-of-the-box config. Most routers plant the
internal
	addresses on the 192.168.1.x network. If both the DSL router and the
VOIP
	router are doing this, then you have the following kind of problem:
	
	DSL Line (Public IP's) --> DSL Modem (192.168.1.0/32 or 192.168.1.1)
--> VOIP
	Router (192.168.1.0/32 or 192.168.1.1) --> Internal network
(192.168.1.0/24).
	
	Notice that both routers think that their address is 192.168.1.1.
When the VOIP
	router gets traffic that it does not know what to do with, it is
supposed to
	hand it off to it's default gateway, which is the DSL modem. But
since it has
	the same IP address as the modem, it cannot find a route to it, and
therefore a
	routing loop is created.
	
	Given this, most verizon routers can be setup in Bridged mode,
thereby the VOIP
	router can be given the public IP address for its WAN port and the
problem is
	likely solved.
	
	HTH,

	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.

	Second, you are correct.  At one time I had a router installed on my
own network, but I had it set up in
	Cable modem -> Router -> VoIP & Hub fashion.  Since my wireless
router quit working, I now have everything
	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 :)
