I have Norton Internet Security 2004 which I have been using for over a year with full subscription and updates etc. I used to get security alerts all the time asking if I should block/permit/always etc which would intefere far too much with any online usage. Eventually I filled up my rule list with individual rules for specific IP addresses with specific port access etc so i tried to create a better set of rules.
While messing about to create better rules, I have prevented Internet Explorer connecting to the internet (Luckily EVE Online still works...phew). I will download Mozilla and hope the auto rule creation will sort this out. But I wanted to know which Local/Remote ports and Protocols (TCP/UDP/etc) I can make better rules for.
I think I should be able to start out with block everything to and from everything, then create rules above that to specify exactly what I CAN do, but it seems I dont know enough about ports and protocols to do this correctly. Can anyone help?
