I am evaluating LnS at present and my query is to do with setting rules to allow SKYPE calls to connect without loss of quality. SKYPE support have relied to my question regarding call quality. Their primary advice is " Please, make sure your firewall/router is not blocking Skype in any way. Try opening UDP traffic both ways to both ports found in Skype's top menu: Tools > Options > "Connection" window; tick the option to use the ports 80 & 443" Being unfamiliar with the GUI can anyone tell me (simply please!) exactly how I configure LnS to allow specific ports?
