Hi K, It would hard to do better than Jim Harrison's article on the firewall client. You might also want to check Stefaan Pouseele's article on the Firewall client communciations as well.ALL applications will use the firewall client unless the mspclnt.ini settings tell it to not use it.

I have some questions regarding the Firewall Client: Who plays the "main part" in permitting which application can communicate with the outside world? The "Protocol Rule" or the "Application Settings" in Client configuration? When there is a protocol rule which permits connecting from a certain LAT but no application settings for this app were explicitly made, is the app able to connect to outside? I mentioned a strange behaviour on my client which directs in this way. When testing around with the app settings: when does the FWC gets the new config? I thought it would get it when clicking on "Update" in the dialog box? Is this correct? Or do I have to wait for 60 minutes? Furthermore the article "ISA Clients Part 3 - The Firewall Client" is not really clear to me. E.g. what does "P" "L" or "E" for the name resolution mean? The whole Values for the different Keys and what they mean is not mentioned in the article. I hope Mr. Shinders book is coming soon, maybe this makes configuring the FWC more clear to me!!
