PPTP gives the user an IP address on your private network which is
encapsulated inside the traffic sent on the public Internet. The
packets come out of the PPTP server and are routed on your private LAN
like any other packets on that segment. One thing PPTP doesn't do a
good job with is giving you access back out to the Internet. When you
have the PPTP tunnel open, all the traffic goes through the tunnel.
Microsoft's PPTP server doesn't do a good job sending traffic back out
to the Internet if the user is trying to simultaneously access the
private LAN and public Internet.
You may want to check out my company's product, the NOC 4000 Extranet
Access Switch. It acts as a PPTP server, and IPsec tunnel mode server,
and includes the ability to customize a user profile which includes
custom filtering, bandwidth management, and security parameters. Our
Web address is http://www.newoak.com. By the way, our product can
handle the 'split' traffic case described above.
