[pptp-server] Poptop and port 47

[Joshua Nekl]

Thought I'd add my $0.02

We use PPTP a lot. I wrote my own ipchains firewall script and found that the following needs to be allowed through the firewall for the linux PoPToP pptp server to work with MS pptp clients

protocol 6(TCP) port 1723
protocol 17(UDP) port 137(nebios-ns)
protocol GRE (47)  --gre doesn't use ports--


Hope this helps
