In the log of the ZoneAlarm Security Suite firewall I noticed that
there are 100 blocks about every three minutes. To me, decidedly
non-expert as I am in all matters firewall, that sounds like a whole
lot and a potential drain on my system's performance. What do you guys
think?
ZoneAlarm is designed to bombard it's user with useless information to make
you think it's doing something useful. ZoneAlarm and all other "personal
firewalls" are not firewalls, they're snake oil. It's not possible for the
host (computer) it's running on to be behind the firewall; you're either on
a machine exposed to a hostile network (ie one outside your control) or
not. ZoneAlarm cannot make a hostile network not-hostile, nor can it
separate your network from a hostile one. You need a router for that.
You're better off getting yourself a Linksys WRT54GL, GS, or equivalent
(
http://www.dd-wrt.com/wiki/index.php/Supported_Devices has a list of the
best routers to use) and routing your connection through that. Dedicating
the router to this task is inexpensive, allows your network to expand if
you ever have friends bring a computer over or if you get another yourself,
and is actually effective as a firewall.
And give the guy who ripped you off by selling you ZoneAlarm a real earful.
I did notice that almost all of them use the UDP protocol and come in
on port 27468. I have no idea why this is...
Google for 27468 udp for information. It looks like that port might be used
by BitTorrent on some sites, but without being to take a look at netstat on
your machine when you're experiencing this, I can't really narrow it down
more.
