Hi, I've just started evaluating LnS and I have a few questions: 1) I don't understand whether I need to run the LnS service. I downloaded 2.05p2, do I need to download the service separately and run it? Why isn't it part of the 2.05p2 download? 2) Cisco VPN over UDP: I allowed the Cisco VPN client full access under "Application Filtering" Yet, when I try to connect LnS still blocks UDP packets to port 500. I have to put another rule under "Internet Filtering" to allow UDP 500 both ways for Cisco VPN client only. Why is that? It doesn't look like I have to do it for IE, I just allow it access in "App Filtering" and it works, it doesn't need extra rules for TCP 80, etc. I even tried specifying port 500 for the VPN client in the "Application Filtering" but it doesn't work without the extra rule in "Internet Filtering". Is this how it's supposed to work for UDP packets or is this a bug? 3) DLL monitoring: I have the Yahoo toolbar in IE but it certainly doesn't prompt me whether I want to allow that dll to access the Internet. The dll doesn't even appear in the list even though I have "Enable DLL detection" checked. 4) Does LnS support executable change detection? I've seen other firewalls that keep an MD5 of the executables and dll's and they warn you when they are updated. If not, what app would you recommend for this functionality together with LnS? Is it even an useful feature? 5) It does not look like LnS has the concept of trusted vs. non-trusted networks. Is the way to do it by adding custom rules in "Internet Filtering"? 6) What is this advanced option "Network interface autodetect, IP to exclude"? The help is not very ... helpful. Thank you for your help.
