vonage is killing my web server

hopefully someone can help me out with this one. I have had a web server and email server in my home for years never had an issue. Ever since I got Vonage I have been having issues. my web server loses internet connectivity still works on lan. basically Vonage is taking all available bandwidth even though no one is on the phone. I have tried QOS but it still knocks down my server. has anyone else ran into this. my Vonage works great but my email server needs to work too. I am using a liksys wrt54g router with the wireless disabled I installed the latest hyperwrt also. Thanks in advance.

what model of Vonage adapter do you have?

where does it sit in your network topology - ie
what is the relationship between modem, router and
phone adapter?

What Vonage device do you have? If it is really taking up all the bandwidth even when no one is using the phone, then you have a serious problem - my WRTP54G only sends out a quick ping every minute or so to the Vonage servers as a "keepalive" and the bandwidth it uses when I am not on the phone is so minimal as to be unnoticeable.

Since you have HyperWRT (I'm presuming it is the latest Thibor release, right?), download WallWatcher or some similar package and start watching the packets flow on the router. This will allow you to determine exactly when Vonage is using lots of bandwidth, and how much.

Also, you have your Vonage adapter BEHIND the WRT54G, right? Modem -> WRT54G -> Vonage device and web servers. ?

If you put the Vonage device between your WRT54G and your Internet modem, then the issues you are experiencing are probably more related to issues with the Vonage unit as a router than the bandwidth it is taking up.

I have the latest version of hyper wrt 1.21 I believe on the router. I just downloaded the latest linksys version here at work and I am going to try that out as they are up to ver4 no and the hyper wrt is based on ver 3. what seems to be happening is the ports shutdown for my server yet Vonage just keeps on chugging. it would last about a week with qos on I tried disabling QOS last night and just doing forwarding but it didnt even make it through the night.
I am using the dlink adaptor I forget the model name but it is the non router one and it sits behind my router.

topology is
DSL modem --- wrt54g v2.2 ---- dlink Vonage adaptor

sadly I am a network administrator and I am even having issues with this. I am guessing I am overcomplicating it and it will be a real duh answer. thank you again for anyinsight you guys can give me. I am kicking around the idea of picking up a pix firewall and calling it a day as I can configure the living crap out of that.

I hear you. Frustrates the heck out of me when linksys, d-link et al take a perfectly reasonable concept with a name commonly understood by netadmins and insist on giving it a more "friendly" name.

Anyway, sounds like you have a d-link VTA (as do I). The topology looks correct - it matches mine :-)

I have a Westell DSL modem (Verizon) then a Netgear FVS318 then the VTA conncted just like a PC or other device. I do port forwarding for a web server but not a mail server. No qos capability in the FVS318. Nothing seemed to break when I added the VTA to the picture.

My VTA uses DHCP to get an address, but the DHCP server is configured to always give it the same one.

How did you determinte that Vonage is consuming all your bandwidth (what tool did you use)?

The only other "basic" thing to check is to connect to the VTA and make sure it isn't using the same IP address as something else on your network.

I guess saying it is using all my bandwidth is incorrect. my Vonage is working great however my server is doa to the outside world. my server also does dhcp for me and I gave the Vonage adaptor a reservation so it is not sharing an ip with anything else. I keep an eye on traffic with wallwatcher. my server is a full fledged domain controller so there is alot going on and having it go down makes things a bit infuriating for me. I am thinking it is a router firmware issue more than vonages fault. seems like it is just locking qos or something on Vonage and letting nothing else through. I am gonna reset the router and flash the latest linksys firmware on there and set everything up on it fresh tonight and soo hwo that works out. if that does not do it I am at a loss.

HyperWRT was taken over last year by a guy named "Thibor", who has added a LOT to the project. 2.1b1 is very old, check Thibor's site at http://www.thibor.co.uk/ for a MUCH more recent and functional HyperWRT.

I installed the latest linksys firmware rest the router to factory then proceeded to make all the needed changes.
I used QOS by mac giving my server highest priority then gave the Vonage high priority as well as put the Vonage IP in the DMZ and set the appropriate ports to be forwarded to it also. I also disabled the wireless functionality as I have another AP that handles that. So far the calls seem to be ok at least I have not heard any **** from the fam as of yet. And my server seems to be up for now I guess the big test will be tomorow when I go to work as that is when it seems to always go down when I cant do a darn thing about it go figure! If this doesnt work I will be trying the thibor firmware next. Thanks for the replies I will keep this thread updated as to my progress.

I'm curious why you had to open/forward ports for your phone adapter. I didn't have to do anything special with my FVS318/VTA
combo. Doesn't SIP use STUN for traversal of nat gateways?
