I might have the chance to get a near free 506 or spend a couple hundred $ for a 506e(both used) And I was wondering besides the 506 beint 10mbits and the 506E being 100m, what are the other major differences I should be aware of?
Check this link out. http://en.wikipedia.org/wiki/Cisco_PIX - Shows some of the specs. than the interface speed there are a few other deltas such as throughput and max connections
