Worrying indeed - I use Black Ice products personally as they were used at a major international bank I worked for.
Still yet to see any patches from them so I am shopping around.
I think I may go with Richard's suggestion of a hardware firewall.
Richard, it's an old Compaq 233Mhz PC. I am sure it can handle 2 NICs. What do you recommend as an OS ?
Quite familiar with Checkpoint 1, Nokia firewalls, Norton etc
What, if any are the issues with NAT and an ISP ? My ISP may or may not support fixed IP - not an issue up to now.
Also considering a wireless router where NAT becomes an issue.
Cheers
