VPN via pptpd
For a while now I've been working on setting up a windows-compatable PPTP VPN server on my Debian Linux machine with Firestarter. Today I managed to get it working ... almost.
Details:
I have pptp configured with a local IP of 10.0.0.4 (my server) and it hands out an IP of 10.0.11.0 to my windows machine.
I can ping 10.0.11.0 from both ends (Windows and Linux). I can also ping all of my home servers/machines just fine (10.0.0.*) but cannot connect to any thing on my network (like web, telnet, ssh, etc). I finally discovered going in and stopping Firestarter fixes this. Firestarter is apparently blocking those connections.
I changed the IP addr that pptp hands out to 10.0.0.200, thinking having them on the same network range may help, but I see the same behavior (works with firestarter stopped, fails when it's started).
When I watch tcpdump I see :
15:36:05.006988 IP 10.0.11.0.3159 > 10.0.0.4.www: S 3088986561:3088986561(0) win

It seems to me that something in Firestarter's settings is blocking the connections from my VPN connection from reaching my web server. I'm at a complete loss to what I need to change to fix this problem, can anyone lend a hand?
