I have a Unbuntu server that i am running as a router that I am trying to move to a zen server. I have taken all of the config files and installed all the packages that are installed on the server that is running now. When I replace the server that is running now with the zen server everything works except the IPSec tunnel. I have no experience with IPSec but I have read up on it and to me as long as I have the right keys then it should work. Am I wrong about this?
