Yep, I realize that, and you make an excellent point, James. Currently my "netrowk" is a cooker box that i use as a print server, and a winXP box that i use (under protest - but propriatary software that i haven't beaten into running with linux yet), and occasionally this laptop, to a 4 port "home" type switch/firewall box. Believe me, linking my office network to a dial-up isp with no firewall is NOT normal behavior here. Just seemed like interesting behavior for a network - until i remembered that my 4 port "hub" was a switch with a dhcp server that thinks it's the internet gateway. <embarrassed grin> v.
