Hi, I have the latest Firewall that could be downloaded (1049). The Firewall prevents reliable Internet access with access blocked every few minutes. I tried a long list of actions. These included resetting EST firewall to default settings. The problem applied with Version 3 of ESET and Version 4. I can only assume the registry is screwed up in some way. There's a list of what was tried at : http://tekblogs.com/tb/2009/06/26/internet-access-blocked-by-eset-firewall-solution/ Hope it helps.
