A web site to check out your security :)

I have just gone through Vista Firewall Control and i find no Low, Med, or High settings, I can allow incoming / outgoing or both connections for all applications, all my applications that need to update (eg) Vipre, CCleaner etc update fine.

It's been a long time since i used the ICMP tweak on XP, i stopped when i got a new router with a decent firewall.

If you've got ICMP traffic disabled in it's entirety then you'll have networking problems. LAN. Local. Not internet issues so yes your programs will update and work fine.

No ICMP traffic not disabled and all our Computers are networked and connect, Router Firewall is enabled.

This may be the answer as this needs to be enabled when my ISP was using DLM (dynamic line management) when i first started with my ISP

Ping is a form of ICMP traffic buddy

As i don't need to advertise my router to the world i leave it off with no issues

Hehe, this is just funny
