Don't think my switch changes any IP headers, it just either routes them 
somewhere or doesn't based on a set of rules.

I thought a switch just dealt with stuff in one network address space, eg 
you use it to simply provide enough sockets for everyone to connect into 
something else, and it just send unmodified packets to the right place.  A 
router however connects two different networks together, and has things like 
port forwarding, NAT, modifying the IP headers etc.

Or maybe I'm completely off track as I'm no expert, that's just based on my 
experience with working with things labelled as "routers" and "switches".

Didn't this come up before when you told us about this?  I'm sure everyone 
explained to you some of the benefits of the more pricey switches.  Was your 
post just because you were surprised how configurable a switch can be?
