I have a Lan with 6 pcs, one of them I used as a server with windows 2003 server. I want to share Internet between PCs on Lan , using VPN , and just how has valid user on server can access to Internet. I setup VPN on server, the problem is steel some PCs without using VPN have Internet and I can't control them , I use DHCP and all pcs have IP forom 10.0.0.11 to 10.0.0.100 ( server IP is : 10.0.0.10)and I setup VPN to set IP from 10.0.0.101 to 10.0.0.121
other PCs can access to ftp , pop3 ... without using VPN and just browsing web pages need to connect VPN.
What is wrong? how can I manage my Internet usage?
