I've been beating my head on this for a couple of days now and cannot get PPTP to pass through my PIX 501 so we can get our wireless vpn connections up.
When I initiate the Microsoft VPN (Windows XP Laptop) connection from the client on the outside (Ethernet0 on the pix) to the W2K3 Server running RRAS, I receive an 800 error. However, when I issue a "sh conn", I can see the connection being created, but it has the flags SaAB. After 2 minutes the connection will time out and will be torn down. Not sure what's going on here, but I am able to ping the server from the pix and vice versa.
Now, if I plug the laptop into one of the four ports on the 501, I can bring up the PPTP session without a problem. So, I know the server is working correctly. The only gotcha I can think of is that the server sits on a separate VLAN than that of the pix, but this should not be a problem because I can connect without a problem from the internal switch in the 501.
Network layout is Laptop => WAP => PIX 501 Outside => PIX 501 Inside => Core Switch => Win2K3 RRAS Server
The wireless network is 192.168.192.x and the internal network that the pix is on is 172.16.1.x, but the Win2K3 server is on a separate VLAN addressed as 172.16.253.x
Here is the config:
