I've got everything to work except I cant ping inside servers. Here's a ipconfig from the VPN client to the RADIUS server:

Ethernet adapter Local Area Connection 3:

Connection-specific DNS Suffix . :domainnamelocal

IP Address. . . . . . . . . . . . : 192.168.100.2

Subnet Mask . . . . . . . . . . . : 255.255.255.0

Default Gateway . . . . . . . . . :

H:\>ping 192.168.1.10

Pinging 192.168.1.10 with 32 bytes of data:
