Can't connect to Nortel Contivity VPN with my D-Link DI-524 wireless router.

For the last week, I've been trying to connect to the VPN at work, using the Nortel Contivity VPN client, through my D-Link DI-524 wireless router, and it's just not working. It makes the connection, and then immediately loses it. I have flashed the firmware to the latest version (1.05) and followed D-Link's configuration instructions, but nothing is working. I know it's not the PC, because the VPN connection works on dial-up.

Anyone have any suggestions?

Update: problem solved. After struggling with this for a week, I called D-Link Tech Support (you may recall I've raved about them before). They had me disable Norton's Internet Worm Protection and Bingo - in like Flynn! Norton thought the VPN traffic trying to get in was a worm; specifically:

Rule: Default Block Bla Trojan Horse
Direction: Inbound
Local address: 192.168.0.102
Local port: 1042
Remote address: 159.247.3.231
Remote Port: 500
Protocol: UDP

I have the same issue. I was unable to make the VPN function. Then I turned off Norton firewall and immediately it works.

So the question is how to set the Norton firewall so that it does not block. I have already given permission for the Nortel software to have "general" permit status.

Does the Norton Firewall include Norton Anti-virus? Can't you just turn off the worm protection without having to disable the firewall?

I followed the instructions, but it did not work. Any other guidance out there?

I can connect without problems by turning the firewall off. I am using a DI-514. I did not follow the D-Link instructions. It worked with the default settings (IPsec enabled for instance).

add a rule to permit any UDP/TCP traffic from your VPN server to your machine.

Just so you know, this is not a d-link issue. I have the same problem with a linksys router. I'm still looking into specifically how to configure the worm protection software (which is where the issue lies) I'm about 98% sure it doesn't involve configuring your router.

In fact, check out this link (you'll have to translate UCSF specific stuff for you)
