Hi Haroon,
Please be aware that Cisco positions the 2811 as "2xT1/E1," which would at
most be 4 Mbps of throughput. The 2821 gets a little closer, with
"4xT1/E1," or at most 8 Mbps throughput. The 2851 finally gets you in the
zone, witch "6xT1/E1." Naturally these are just guidelines and are somewhat
of a dart thrown at the wall, as it's impossible for Cisco to know exactly
what you'll be implementing in your network and asking your ISR to support,
protocol and feature-wise. But I generally try to follow their
recommendation on this sort of thing so as to stay well within a margin of
error...
Cheers,
Scott

Thanks Frog and Seonghui!
So, 2811 is good for anything 10megs and below?
Does every router with public interface have to have firewall behind it or
IOS firewall suffice as default gateways have firewalls.
Other weak point I am starting to see is the main switch (3750) after the
internet router (2811) that all other routers connect with...

Haroon
