So what is the benefit of a router AND IPCop on a
dedicated PC (hardware firewall)? Some, none at all?

Can someone describe what the router part actually
does. From product descriptions on the web it seems a
router is

ADSL modem + NAT + DHCP + Firewall

Which bit of the above is the router part or is it
something that is missing.

Part of my problem is there seems to be the usual
computer problem of a blurring of terms. You look on
the web for an ADSL modem and what you get is an ADSL
router with modem or you look for an ADSL router and
what you get is the router part only.

Another question has just occurred to me. How can you
have an ADSL router without the ADSL modem part? Isn't
that just a router?

I am currently assuming that an IPCop PC will handle
all the routing/NAT etc.

There seems to be a large overlap between what the
router provides and what IPCop provides but I'm not
sure if the parts where it doesn't overlap are
critical.

Now more confused than ever.
