@george1421 No idea. But the default settings for Win7 and Win10 don’t let tftp commands work. It took me a long time to figure that out, because I was thinking exactly as you were, that all outbound was allowed. There must be more to it that causes the issue - and I don’t have any desire or need to figure out why lol. Incredibly rarely do I myself need to test tftp from windows… because I always just use Linux now.
