[AccessD] OT: DSL/IIS/Viruses

My DSL router, which is not wireless, has a built in firewall.  You have
to disable software firewalls in order to install the router.

If it touches the Internet in any way, except through
a firewall, it's vulnerable.  Some wireless routers
have a built-in "firewall", but I'm not sure how
secure they really are.  I never trust multi-function
systems like that.  I use a wireless router for
wireless connections, and a firewall for a firewall.
