RT31P2 + Arris CM450A: Can't get a DHCP lease

Posts: 4

Hello,

I recently received my Vonage starter package with the Linksys RT31P2 router, and I am having some trouble obtaining an IP for it. Up until this point, my internet connection has routed through a Linksys BEFSR41 broadband router. It has been able to get an IP address cleanly for several months now. My ISP (Ygnition) does require MAC address registration, but the MAC addresses for both routers have been given to them. In addition, I attempted to clone my BEFSR41's MAC address on to the RT31P2, just in case it was a MAC issue on Ygnition's end. No dice.

My speculation is (and this is backed by Ygnition technician comments) the Houston Metro area DHCP server is VERY slow (in their own words), and I think the RT31P2 is timing out when attempting to fetch a lease. When renewing IP address, I can tell you that my BEFSR41 waits MUCH longer for an IP than the RT31P2 does. Is there any way to adjust the timeout on the RT31P2? I could not find anything in the HTML based setup, but does the RT31P2 have a telnet interface that allows more fine tuned configuration?

Any help is appreciated. If I can't get this resolved, I am afraid I am going to have to return the kit and ask for a refund, as I simply cannot get the service to work.

that's pretty sad on the isp's part. I would look for another one, there must be a few in houston.
you can access the web based interface of the rt31p2 at http://192.168.15.1 but I don't think there's anything there that can help you.
of course you could always leave the befsr41 there and plug the rt31p2 into it.

What ports would I need to forward on the BEFSR41 to the RT31P2? I assume I could give the RT31P2 a static IP and forward all the Vonage ports easily enough. Hmm, that might just be a solution.

probably won't need to forward anything, or even so I would use dmz before I would bother with ports. at any rate, here they are:
5060 – 5061 (UDP)
10000 – 20000 (UDP)

Before I ask anymore stupid questions, is there a document on how to do this? Route the telephony router through another router? I am not sure of the specifics, and I don't want to ask a million and one questions Smile

all of this info is available here (forum search) or at vonage.com (help)
that setup is not uncommon and is the only way the Vonage pap2 device works with more than it sharing the broadband line.
here is a link on how to do your setup:

Thank you so much. My telephony router now has a static IP and is setup as the DMZ for my primary internet router. The phone is working great, I seem to be gettting good QoS Smile

Thanks again for all your help!

If by QoS you are referring to the QoS feature on the RT31P2, it is completely useless if it's sitting behind or parallel to the rest of your network. Unless ALL of your network traffic is flowing through your RT31P2, the QoS is not managing your network's bandwidth usage.
