Contivity VPN Issue

Posts: 1 · New Forum Member Joined: May 10, 2004 Posts: 1

I have Vonage at home in addition to a Linkysys 802.11b wireless router. For some reason I am unable to connect to my Contivity VPN at home ever since I started using Vonage - the message I get is "checking for banner text" and then it boots me off. Now I disconnected the Vonage router (Motorola VT1005) and my connection works so it must be something to do with the configuration of the Voip router as opposed to the Linksys router. Anyone have any ideas what this could be?

Thanks

I am having the same problem. I am wondering if this has something to do with the voice terminal blocking IPSEC traffic and whether or not this behavior can be changed.

Anyone have any ideas?

Try the "Installation with multiple computers(alternate setup)" available in the installation section on the Vonage website

http://www.vonage.com/installation_multiple_alternate.php

You lose QoS capability with this. But given a choice between QoS and not being able to connect, I take QoS. You might also need to look into the installation and troubleshooting guide if your phone adaptor is not able to connect. Some ports may need to be enabled. I just placed my phone adaptor into the DMZ.

I had the same problem with VPN Nortel Contivity and I am now using the Alternate setup and I am able to connect to VPN. However according to Vonage this does not allow the Phone adaptor to prioritize voice over data traffick, which affects call quality. According to the user guides that came with the Vonage/Motorola package AND on page 28 of motorola's manual on their website
http://broadband.motorola.com/noflash/customer_docs/user_guides/514013-001.pdf

The Motorola VT1000v supports a VPN connection with IPsec. Vonage cust support says it does not. I got nowhere trying to call 5 different motorola technical support numbers. How does a DMZ work and where can I look up documentation on how to set one up. Thank you

I'm having the same issue, but have some additional information. I have 2 different Contivity servers to connect to. One has NAT traversal mode enabled the other one doesn't. The one that doesn't have it enabled works and the one that has NAT traversal turned on doesn't.

I'll keep playing around and see if I come up with anything else.

So a bit more information. In my last post I said that VPN did work if you were connecting to a Contivity that didn't have NAT traversal enabled. That is partially true. I was able to get most things working. I was able to connect, map network drives, connect to Exchange and surf web pages to a point. I found that if the web server uses Windows authentication then it wouldn't work. I would get a pop up that asked for my username and password (so I know I was hitting the server) then nothing. Took the vt1000 out of the mix and no issues. So it's working to a point.

I did call customer support and they said that they didn't support VPN/IPSEC but I could put a router in front, etc, etc. Unfortuantely I really want thw QoS features so that's not really an option as my upstream can be full at times.

I also grabbed the latest Contivity Client code to see if that made a difference.... it didn't.

I have the same problem. I have a Linksys BEFSR41 4-port router and I'm using Contivity client 4.65. I get through if I bypass the router, but with the router in the loop, I still get the banner text message and timeout.

I called Linksys and I was told to use port forwarding to forward the WAN request directly to my PC. Checked the log and the problem seemed to be on port 500. Did some research and confirmed I need to fwd UDP on port 500. I have IPsec pass-thru enabled but it still doesn't work.

Where can I get the latest Contivity client? I couldn't find it on Nortel's ftp server. Is it still free? Their site mentions a 30-day trial.

Has anyone made progress on this issue? I am seeing it using Vonage's Linksys RT31P2. I have forwarded port 500, but, that was no help.

FWIW, I got this working through the Linksys router/phone adapter. Norton Firewall on the client computer was causing the problem. I don't know why it was working before without the router, but, setting the IP address of the Contivity server as an allowed exception cleared the problem.
