I am running Windows XP Professional SP3 on my Dell laptop.
I use a VPN to connect to my work network to work remotely and control the computers and servers etc. I am connecting at home from an O2 Broadband router (Thompson) which I have access to the admin panel.
I can sucessfully connect to the VPN and get an IP address on the work network. However, I cannot RDP or VNC any of the computers.
I have made sure that the ports are pointing to my laptop using the routers application sharing options, I have turned the laptop and router firewall off aswell. Still no luck.
Pointing the ports at a Win7 laptop allows the VPN to work as expected straight away. Just not on the Windows XP machine for some reason.
I am connecting via WiFi on both laptops.
