I need to verify that the second example is what I need? If so do the remote users have to have static IPs or can I use a general ACL statement that allows all PPTP traffic through the PIX and then being prompted for auth at my server. I know it may be one more hole in the firewall but it is critical to allow these folks to vpn in. Any help is greatly appreciated.
Re: confusion on sample config for PPTP/GRE pass through on PIX
If the server is on the inside and the clients are on the outside, then the 2nd example is all you need. The server needs a static IP address entry, the clients don't need anything special other than to point to this static'd IP address for the connection.
The ACL on the PIX outside interface has to allow both GRE and TCP/1723 for it to work. Other than that, you should be good to go.
