I've been testing Smart Security 4 for a couple days now in preparation of a deployment on our company network. So far, I've had very strange issues with the Firewall. In order to get even a volatile internet connection (in automatic mode) I've had to tune it quite a bit as well as look at the logs to try and get an idea as to why my connection drops all of a sudden. Before any tuning, I was completely blocked from all internet access on any port/program. According to the logs, my last outage was: "Packet blocked by active defense (IDS)" Source: 126.96.36.199:80 (which is Wilders IP btw) Target: my private IP Protocol: TCP During that outage, all internet connected programs were disconnected. So far, I've made the following changes which have improved my connection but I still get random disconnects: Disabled ARP and DNS poisoning detection Enabled allow UPNP in trusted zone Enabled maintain inactive TCP connections Switched to "Applications marked..." for protocol filtering. So, any idea why the IDS drops my connection? Obviously, disabling the firewall works like a champ, but that's not an option.
