Firewall Reprise
by Roger Barnette
I received some technical corrections to my
last home networking article. Please bear
with me if you aren't the technical type.
In short, the firewall and NAT features
of a firewall/router/switch will
well protect your network. However...
I was mistaken about the randomness of DHCP.
Unless your ISP intentionally enforces this
your IP may not release and renew in a timely
manner.
The other advice I received was that a firewall,
generally is best at protecting other computers
connected to it. This reinforces the value
of a firewall/router/switch for networks
that require the highest level of security.
Firewall software installed on a personal
computer would be less dependable.
If this reads like confusing techie talk,
please email me and correct me or ask questions
and I would be glad to take some time
to discuss it.
