Can't ping remote computers except the VPN Server

Situation: You just created a VPN on Windows 2003 server. You can establish the VPN and ping the VPN server. However, you can't ping any remote workstations' IP.

Troubleshooting:

1. Ping gets time out.

2. Tracert remote computer's IP stop after reaching the VPN client PPTP IP.

3. No firewall blocks the ping.

Cases and solution:

1. The IP is not routed over the VPN server. Enable IP routing.

2. Both sites, VPN server and VPN client, are using the same IP range, for example, 192.168.1.x/255.255.255.0. Assign the different IP range or subnet.

3. Both VPN server and VPN client are assigned the same IP by a router. For example both are using 10.0.0.110. you may assign IP using RRAS IP pool or switch DHCP from the router to the  Windows DHCP (case SC101905).
