I spotted a common mistake on the vpn_server page. It's at the very
bottom: Item 20.
+++++
If the VPN server is behind a router, Port Mapping will need to be
done on the router. Standard port usage is 1723 & 47 for PPTP. Port
usage for IPSec is 500, 50-51. These ports will have to be forwarded
to the VPN server's IP
+++++
There is no PORT 47 involved with PPTP. There is PROTOCOL 47, which is
called GRE (General Routing Encapsulation) which is used to transmit
secure information before the full VPN is implemented.
NAT routers are highly restrictive of anything coming in - that's
their firewall capability. Most only pass the most common protocols,
such as ICMP, TCP, UDP and passive FTP. On the less expensive SOHO
routers there is usually no provision for allowing other protocols
thru unless the designer explicitly puts them in on a one by one
basis. That's what "PPTP Passthru" is all about - the passthru for GRE
Protocol 47.
I wrote the author of that website.
