Hi all,

I set up my first IPtables box, doing NAT and port forwarding. I've
managed to Google most of the kinks out, but this one perplexes me.
There is a Win2K VPN server behind the firewall, using PPTP. It will
accept connections, but chokes before accepting the username/password.
The most I've been able to figure out is that it has something to do
with protocol 47.

All other forwards (HTTP, HTTPS, POP, SMTP, Telnet) work fine. Any
ideas?

Thanks,
John
