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.
