I'm sure it must be a static route issue, but I don't know enough about routing tables to be able to fix it.
After following the tutorial on how to setup a PPTP VPN, my Windows 7 client is not able to access the LAN. It only gets all of its traffic routed to the internet.
My client's ethernet ip address is 10.44.44.xxx, and my tomato router is 10.66.77.1. After my client connects, it is assigned the IP 10.66.77.201.
My current routing table:
10.66.77.250 * 255.255.255.255 0 ppp0
126.96.36.199 * 255.255.255.255 0 vlan2 (WAN)
10.66.77.0 * 255.255.255.0 0 br0 (LAN)
188.8.131.52 * 255.255.248.0 0 vlan2 (WAN)
127.0.0.0 * 255.0.0.0 0 lo
default 184.108.40.206 0.0.0.0 0 vlan2 (WAN)
