Hi Marrow,
It depends on what the users will do while connected. Most VPN
connections site idle, so they're not using much in terms of processor
cycles. If your users are transferring DVD images of their favorite TV
shows, then just one or two can be enough to bring your server to a
grinding almost halt. The thing about number of users is are there hard
coded limits to the number of accounts that are allowed to VPN. Win2k
doesn't have a hard coded limit, and Win2003 has a limit of 1000. Do you
expect 1000 concurrent connections?
HTH,
Tom

Subject: [isalist] VPN connection using ISA Server 2000
http://www.ISAserver.org
I am looking for a VPN unlimited connection solution, I see that all the
VPN broadband router can only support maximum 70 VPN Connections in the
router level. However, I need the unlimited one for my own company. What
I am thinking is, I buy a Intel 10/100 Pro S Server Adapter , which can
support hardware IPSec in the NIC card itself( the spec. in intel says
that, that's why it is Server NIC , not desktop NIC), then I use the VPN
function in the ISA Server 2000 to create VPN connection for all of my
client. In the router level I will only let the router enable the VPN
bypass function , which is a common function in all router in Hong Kong.
What do you think about my VPN unlimited solution? The pricing of this
combination will only cost 100-200 more Hong Kong dollar when compare
with using VPN router. Which is very good if I need more than 70 VPN
connections.
the shop keeper tell me it is impossible to have unlimited VPN
connection (I think he mean in the router level), he say even it can,
the bandwidth for 70+ VPN connection can't handled by broadband
connection. Is that true ? I will have a broadband connection of 10Mbps
upstream 10Mbps downstream. It still not enough ? I am not going to
assume they all connnect at the same time (through you can say why I
don't use VPN router if I don't assume it will handle all at the same
time, but I want to make it unlimited in the lowest price, the hightest
price is I link up all VPN router to make it support more than 70 VPN
Connections if one VPN router is over limited).
Very best regards,
Marrow Yung.
