VPN Connection Setup

It looks like I can't as o2 have configured it in such a way that the user can't disable the firewall?

It's probably just a port forwarding/VPN passthrough issue on the O2 router.

Unfortunately I don't know the O2 router, and I've never needed to configure a VPN behind a NAT router/firewall so I've never needed to worry about which ports are involved.

Thanks for your help, I will continue having a look at the O2 router and see if I can find the issue

Hi Guys,
Finally got round to going through a few of your suggestions and got my VPN to connect to my server, well sort of.

I can get it to connect while connected to my wifi but if I try and connect via 3G it brings up an error saying "The PPP server could not be authenticated".

The Server Log file contains the following:

Any idea on this?

sounds like your phone is trying to use PTPP whereas your router is expecting L2TP.

I'm no expert tho

try PTPP (port 1723)

Hi guys,
I'm back again, so I am waiting for BT infinity to be installed and as such BT have sent me out my home hub 3 which I have installed. However I am still getting the same issues when trying to VPN into my lion server?

I have not changed any setting on my 2900 and it too is coming up with the same errors. I am thinking now that it is definitely an issue with my router and as such I'm thinking of replacing all my routers with a single draytek to handle everything including Infinity connection and VPN.

What do you guys think?
