Sorry this is OT but I'm sure I'll get some sensible answers here.
I've been playing with the Sophos SC1000 appliance that scans web pages for
nasties before end users get to see them. This web content scanning malarky
is going to be "a big thing" I'm sure.

appliance on its own DMZ and pointed its default gateway at the Internet via
an el cheapo Netgear router configured to do NAT which is connected in turn

it works fine. This configuration is, I understand, not officially
Time to buy a better router? Any recommendations? The router isn't
configured to do anything odd and I have rebooted it.
I intend placing 2 servers running MailScanner on the same DMZ at a later
date. Is it sensible therefore to buy a decent router/firewall to protect
this segment? Smoothwall / monowall worth a go?
