[Discuss] Trying to connect to internet in Debian

[Kent Borg]

I do use a firewall in one very important way.

I have a personal network, with a physical router box between it and the 
outside world.

A new computer, a Mac, came to live on the network, not mine, not 
actively used, but its contents were need for reference purposes.

Its previous owner seemed to have been sloppy and installed some 
nastyware that occasionally sent junk e-mail. So I added a rule to block 
outbound port 25 (smtp) for all but the IP addresses that needed to do 
outbound port 25.

And then I got the IP address taken off a spam blacklist.

Firewalls *do* have their uses.
