I have questions regarding configuration of the web browser for access to the internet. It appears that the ruleset with LnS uses in/out access on port 80 for web. 1 Does allowing an app in/out access cause security (inbound) concerns? 2. Should the web browser be allowed in/out (both) access to port 80 for surfing the internet, or is outbound access enough? It appears that allowing in/out access is like a server. Is this correct? Does LnS allow the requested connection to 'return' from it's destination, thereby not needing the inbound portion of the rule? My intent here is to understand whether or not I can use outbound only for port 80. 3. Does the web browser require the DNS port/IP to be in 'Application Filtering', or can the browser function properly using the 'Internet Filtering' DNS rule? 4. Is SVChost necessary for a more secure computer? If I block SVChost my PC appears to have no side effects, but i'm not certain that it's recommended block it. Does it provide more security for TCP/IP or anything else?
