Hi Folks,

I am doing comparison study of different firewall products for
deployment at our corporate office. One of the interesting criteria I
came across is the "Maximum VPN tunnels" a firewall appliance can
support. To my understanding, any client establishing a VPN session on
firewall will occupy one VPN tunnel. If that is correct, then some of
the pretty low-end firewalls have upto 2000 maximum VPN tunnels, which
makes me think something may be wrong with my understanding of this
concept.

Similarly, talking about maximum TCP sessions. If have to calculate
how many "maximum tcp sessions" should I have on my future firewall,
is there any rule of thumb that can tell me how I can convert our
total active users into the total tcp / udp sessions, for planning
purposes.

Thanks all
