I have used many Internet firewalls, and LNS is the most powerful one. However, I think adding the following 3 new features will make it perfect. 1. In advanced mode, add two options “When a unknown application tries to access Internet, just block it without prompting” and “When a unknown application tries to access Internet, just authorizes it without prompting” to LNS’s Application filtering. The former is corresponding to “white list mode”, and the latter is corresponding to “black list mode”. Usually the two options will be useful; especially the former one can be used in high security mode. 2. Adding a way to specify domain name as destination address in Internet filtering and Port and IP address selection for Application filtering. There are two reasons: first, many servers’ domain name corresponds to multi IP addresses. Second, for some reason, some severs’ IP address is often changed. 3. Add a way user can define a firewall profile list through which user can quickly change LNS’s filtering setting. Here, a firewall profile is a combination of a set of Application filtering rules and a set of Internet filtering rules. It is strongly hoped to add these new features in new release.
