Hello, I don't think it's overkill and would probably start off with a quad processor for 24 gigabit ports. But I honestly don't know which apps can take advantage of the multiple processors and how the kernel uses smp for networking/routing, etc.
There are other things besides ipsec and routing to consider: deep packet inspection. See http://en.wikipedia.org/wiki/Deep_packet_inspection and http://www.securityfocus.com/infocus/1817. Also, squid can use reg_ex pattern matching to block sites for example. For an acl I accidentally used url_regex instead of dstdomain for a spam blacklist 6.3 MB and simple pages would lock up my processor at 100% utilization for a few seconds at a time. It felt like I was on dialup instead of a T1. I'm using a Via C3 1 GHz. Even if you won't have a large reg_ex blacklist, using dstdomain (normal index lookups) it takes squid about two minutes just to load/index a 6 MB file on my systems. The Via C3 @ 1 GHz are about as fast as a Celeron 500 MHz in the real world, maybe slower. For IPsec without the via padlock hardware encryption driver these 1 GHz C3's can only manage about 10 Mbps using AES 128. With the padlock driver they should be able to do 100 Mbps easily. Sadly the fastest I ever managed using openswan and padlock was about 38-43 Mbps. Either the driver was not well optimized or openswan has too much overhead. Besides that, imagine being able to run a counter-strike server directly on your router. :) -cpu --- Muiz Motani <[EMAIL PROTECTED]> wrote: > Can you tell us where we can order the Nexcom systems from and how much > they cost?
