Hi
Am trying to pass PPTP through a gb200 to a 2003 server. Have opened & tunneled tcp 1723 & GRE incoming, outgoing is default "allow all".
The server prompts for authentication, then times out. Looks like a problem with GRE but the logs at this time announce "rejecting unsupported nat request, proto icmp".
I have included the relevant bits of the logs below. Have confirmed the ISP do no protocol filtering. The client is XP pro, ICF is currently off.
Anyone any ideas?
Cheers,
Richard
That looks like an error message from your server; ICMP type 3 is a "destination unreachable" packet. If I read your logs correctly you are getting a code 2 which equals "protocol unreachable", so I'd have a look at your server configuration.
Does everything work correctly if your client is not behind a firewall?
