I have 3 computers I'm connecting via a mixed wired/wireless network. All of the computers in question are using Zone Alarm firewall. My problem is this, the only way I could get them to network while still using zone alarm (and allowing file and device sharing over the network) was to set the zone alarm firewall to Off. This still allows the firewall to block programs from accessing the internet but I'm otherwise unprotected, so I don't really like the solution. What I'm wondering is do any of the other FREE firewalls (MUST BE FREE) work, maybe be a little better about not bugging you to upgrade to the pro version (if there is one) and allow networking with file sharing? The only other way I've found to do this on zone alarm would be to trust the entire network adapter, which is also something I'm not going to do. Thanks for any suggestions.
