RRAS PPTP VPN Issue
Hi I am having a huge problem with client VPN connections. I have installed RRAS on a windows 2008 R2 x64 machine. The problem comes in when the users connect. The first user will connect to the VPN and everything works perfectly, when the second user connects, the first connected user loses all comms to all machines on the internal network. When a 3rd user connects, the first 2 connected users loose comms. It seems that the last connecting user cuts the initial users off. None of the VPN connections drop, they just aren't able to ping or access any servers or PC's by both name or IP. The server also can't ping back to the connected VPN clients, however it still sees them as connected. This problem is basically limiting us to one VPN connection at a time. All clients are connecting using either Windows XP or Windows 7 and are all using 3G cards. Any help on this would be greatly appreciated.

This is wierd please check if the users are taking ip address correctly from your dhcp address pool and also please disable and firewall and the av on the server and check the behavior http://www.virmansec.com/blogs/skhairuddin

Thanks for the reply Syed. I tried what you suggested. I am still experiencing the same issue though.

I am not assigning addresses from DHCP. I inserted a static pool of addresses.
