pptp & windows XP connects but cannot see pix side

Hi have a small issue with my pptp vpn connection. I followed the instructions as seen on http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a0080143a5d.shtml

the problem I have is that after the PPTP connects to the pix I cannot see any machines on the pix side and vice versa. here is my config:

access-list nonat permit ip 10.10.24.0 255.255.255.0 10.10.25.0 255.255.255.0

Re: pptp & windows XP connects but cannot see pix side

Have you got fixup enabled for pptp, if not can you enable this in config mode:

fixup protocol pptp 1723

Re: pptp & windows XP connects but cannot see pix side

I have never used pptp but I discovered the command "isakmp nat-traversal 20" when I could not see my computer on the local side of the pix when I was attempting a connection behind another firewall.

If I had a public IP address my access worked without this command.

Good luck.

Kevin
