I have a pix classic and a vpn 3000. I'm trying to open all gre to allow one of our clients to use windows 2000 vpn to connect to us.
Here are the ports that I have open on the firewall.
0 esp meaning, all esp.
When I try to open all gre I get the following message:
conduit '188.8.131.52 0-0 gre 0.0.0.0 0.0.0.0' merges with
conduit '184.108.40.206 0-0 gre 0.0.0.0 0.0.0.0'
I get the exact same message when I open all gre instead of all esp, except gre's are replaced with esp's in the error message.
I need to be able to use both protocols. My pix version is 4.1.4
Any help will be greatly appreciated.
