Lehquin;

I'm using a 486/40Mhz machine (running linux) as a firewall to my
FreeBSD machine. And I ran some speed tests on it (ISP is Time Warner
Road Runner service) and I got 570Kbits/sec upload and 1670Kbits/sec
download which is pretty damn fast at these speeds you could dowmload a
entire cdrom in less than an hour. Please no flames about linux!! It was
a ton easier to configure my firewall because of dynamic addressing
issues with linux. Also keep in mind that Roadrunner limits the
bandwidth here in Rottenchester NY.

Regards
Dave
