Need help with setup RT31P2 after a existing wirelessrouter.

Sorry for the newbieness. I wanted to check if what I did is OK, as it seems to work. I am just not sure about security.

I have an existing wireless access point/router (Linksys) with a connection to my ISP (Comcast) through a standard cable modem. I want to keep the wireless connection as it is, because of MAC cloning and a nice stable network. The RT31P2 is hooked up to one of the 4 ethernet ports on the back.

I hooked up my Vonage supplied router RT31P2 and let DHCP assign an IP (192.168.1.100...first on client table). The only way I was able to get Vonage to a dial tone was to set up the assigned IP as a DMZ (open access to the internet).

My question is this the "correct" way to go, and am I exposing myself to potential hacker attack this way?

The included setup CD could did not recognize the (second) Vonage supplied router, nor can I access its web page setup (162.198.15.1)...but every thing seems to work.

Advice?

Thanks!

the cd is generally useless. odd that it wouldn't work except with dmz, I wonder about the "security features" of the other router. if a hacker can break into your...router...then I would love to know what he does.
as far as the web based setup, it's only accessible from the lan side, unless you set up remote administration. if so, plug a computer into a lan port on the rt31p2 and set up remote administration and then you'll be good to go.

I have the same devices as you; however, I configured mine this way:

ISP->Cablemodem->RT31P2->WIreless Router

I simply replicated the previous configuration of the wireless router to the RT31P2, including the MAC cloning. I was then able to my wireless router as an access point only, not a router. I simply let the RT31P2 do all the routing.

The primary purpose for this setup is to achieve the most optimal QoS. Furthermore, I don't have to put anything in the DMZ.

Good Luck.

Ditto what muldrec did!

Well, almost..

I still let my wireless device do the routing. Went from a LAN port on the RT31P2 to a LAN port on the Linksys BEFW11S4 wireless router and made the appropriate changes to the settings on the BEFW11S4. ( I turned DCHP off and I assigned the IP address to 192.168.15.2) The settings on the RT31P2 were left at default.

I use the BEFW11S4 for the router because I still wanted the firewall protection.

This latchup has worked flawlessly for me for months!

Good luck!

i believe this is the better setup:

modem>wireless router>rt31p2

connect 1 of the LAN port of your wireless router to the LAN port of the rt31p2. you don't need to set it up in dmz, just forward this ports on the ip of the rt 53, 69, 5060, 5061, 10000-20000. and if you don't have any computers connected to the rt, you don't need to worry about putting it to dmz

The RT31P2 must be connected through its WAN port, or else the voice service will never do anything.

... that is, unless someone has evidence to the contrary.

BJMIGUEL:

I'm certain that your belief is a qualified belief, based upon the access and application requirements of the user.

I am interested in the qualification of your belief, or in other words, why you believe your setup is better.

Thanks for sharing.
