Nortel Contivity VPN Client Issue with Belkin F5D8631-4 ADSL Router

I used to be able to connect to my company's VPN and work from home no problems. Recently, I tried connecting and was unable to do so. I was pretty sure the issue was on my end because I was able to connect to the VPN from the wireless network in the office. Anyway, I have resolved the issues and all is now working again.

It turns out that I hadn't attempted to use the VPN since my last router died and I had changed to the Belkin F5D8631-4. Although this router claims to support VPN pass through it wasn't working for me.

There's a compatibility issue between the 2.00.13 firmware and Nortel's Contivity VPN client. There is a pre-release firmware version 2.00.18 available here which resolves the issue. As it's a pre-release firmware it won't be found by the auto update feature in the router itself and so you need to download it manually.

It has resolved my VPN connectivity issues and I haven't yet come across any other issues with the firmware version. So, if you're having similar VPN issues on this router, give this firmware a go.
