I'm interested in connecting two windows 2000 machines via
vpn, each is on its own network in a different state. Each
connects to the internet via Verizon (DSL). My question
is: How can I connect them via vpn when there's a router
on both ends? The computer i'm trying to reach has an
internal ip address, the router has the only wan address.
Is it possible to go thru the router to the destination
computer?
 
Open either port 1701 (l2tp) or 1723 (pptp) on the router and forward the
packets to the IP address of the computer on the LAN.
 
It would most likely need to be PPTP as L2TP requires a machine certificate on each
machine and L2TP does not work with standard NAT, though their is a NAT-T upgrade.
For PPTP you also need the routers to allow protocol 47 GRE which is often referred
to as "pptp pass through" and some routers such as certain Linksys models may need
SPI disabled, if that is an option, for PPTP to work through it. It also helps to
configure the vpn client connectoid to use PPTP as server type instead of auto as W2K
will try L2TP first by default. --- Steve
