Do blade-logic application servers need access to the internet to download patches, check licensing or anything else? We are thinking of isolating our servers and restricting access to the internet for security reasons and I am wondering if anything will break. If internet access is required for patching or licensing what protocol / ports are required or how do I check the configuration?
there are offline downloaders you can use instead of opening up access. you run the offline downloader from an internet connected system and copy the patch payloads over to the restricted env.
