Windows NT 4.0 and VPN

You can really set up as many as you need but you don't want to have any spare open ports that are un-needed for a variety of reasons, one being security. You never want to have any more ports open to the outside world than you absolutely must.

Hope this helps

The server will (claims to) support up to 256 PPTP ports. If you consider that the computer has no trouble handling your 10 or 100 megabits/sec ethernet, it will have no trouble handling some large number of pptp ports coming in over, say, a T1 lineat 1.544 megabits/sec. When I first set up pptp here I was running 40 ports on a 133MHz box. You have lots of growing room.

Be aware that each port DOES reserve some memory. I cannot find the reference, but I clearly remember setting the number of ports high and turning on all protocols, and running out of memory. (I was using 64Mb at the time on that test box.) Your machine might benefit from more memory.

Good luck.

It does not matter for performance how many ports you install, what matters is; how many simultaneous connection will you have at the most. You did not mention how much memory you have installed on that computer I assume you have atleast 256MB memory. Memory is a big player, however CPU is very important. Unlike regular file and printer servers, a VPN server uses encryption. The process of encrypting and decrypting is the main resource a VPN server requires.
Now for your question, if the aboveserver will be able to handle more than 8 simultaneous connection?
If the only thing that server is doing is VPN, the answer is yes. However if the server is also acting as a file, printer, or application, server than you will see some slow downs.If you have a firewall and the firewall is hardware based (not software installed on a computer) then your best solution might be to contact your vendor if its possible to put in a card that makes it into a VPN server, since this is hardware based rather than software based its going to work much faster and its cheaper in most cases.
