There are several domestic routers that include NAT and Firewalling. Netgear being a major one. (I use the DG834 in the UK), and it has a very powerful stateful firewall, so I have blocked all machines on my network from sending out on port 25, except for my mailserver machine. When I next visit my parents and grandparents, I'll configure their routers to only allow port 25 connections from anywhere on their network, but only to my server, as I host all their e-mail. _______________________________________________ http://lurker.clamav.net/list/clamav-users.html
