Now its working just have another question:

I managed to VPN in to my office with no issues from my customers site (on their PC). I want to be able to use their resources as well as RDP to a server back at my office.

I can ping their default gateway but nothing on the network, also the VPN is giving me my ISPs DNS settings.

ANy ideas?

tick the box that say use gateway on remote network...

I must admits I have an unanswered case with DrayTek about the VPN connectivity when not using an Application. _ It doesn't work but If I used the same credentials with the VPN client its fine.

Thanks sicon.

That lets me browse the internet but I still cannot route to the network I am coming from.

As an example, im at my customers site logged onto a Domain Controller via RDP. I then want to connect to my RDP server in my office.

A couple of issues I see.

1. DNS uses my ISP servers so I cant resolve anything on my customers network.
2. I can ping my customers Default Gateway but nothing else on the network.

Hope that makes sense
