My network guy made the change, but if was in some priv settings on the server -- allowing the client to initiate a new connection. Totally outside of amanda. I think we were running free-BSD at the time. I can't find similar files right now under Linux, but it might have been in rules.ipf or something like that? It depends on what connection security you have turned on, I guess.
But I hope it gives you someplace to explore ..... if nobody has any internal-to-amanda fixes for you.
