firewall blocks of incoming contacts

Guest

This is probably of no concern but I thought to pass it on by the experts.

I am on a home wireless WPA protected network and connect to the internet
via a router to Cox internet. I use Zone Alarm free as my firewall.

Lately ZA has blocked attempts to access my PC from IPs 68.105.28.12 and
68.105.28.11. The text says "Packet sent from 68.105.28.12 to ..... (ICMP
Unreachable) was blocked ..."
Even though IPs 68.105.28.12 and 68.105.28.11 are both Cox servers, they are
for regions _other_ than the Cox server for the region I live in which is
Northern Virginia which is why ZA blocked them.

I could just ignore the alerts, or, put these servers
cdns7.cox.net [68.105.29.12]
cdns2.cox.net [68.105.28.12]
which correspond to Arkansas, Arizona, California, Connecticut, Louisiana,
Nebraska, Oklahoma into my trusted zone to stop the alerts.

Any suggestions as to how best to proceed?

Does blocking Cox' ICMP requests affect your connection to the internet?
If no, then just ignore the messages. Blocking incoming ICMP messages is
smart and *should* have no adverse affect.

In particular if you're not a COX customer, block them and forget them.

If you are a Cox customer, use manual blocks a few times and see if you
end up getting consistantly disconnected. I doubt you will. If there
are no ill efects, block them.
You could also ask COX if they're your ISP.
There really is no reason to need to check for your machine,
especially from all those locations.

I wouldn't put them in the trusted zone. If you were required to respond
to them, you would have been told so.

Thanks to both answers. It does not affect my connection. I'll just ignore
them for now.
