VPN Client behind PIX connecting to Concentrator

THis is a vey basic question but I am having problems. What ports must I open on mY pix box to allow an internal VPN client to pass? I am even thinking of just doing TCP 1000 instead of the standard ipsec ports.

Thanks!

Re: VPN Client behind PIX connecting to Concentrator

If you're talking about being inside the PIX going out, then unless you're blocking any ports, none. You do need to make sure your VPN client software supports NAT-Traversal. Cisco's client does, but Microsoft's PPTP client doesn't by default. You can go to the following link to get an update.
