So I have managed to get my L2TP on Astaro to work with Windows clients and my Iphone internally, but I am trying now from the outside world and It doesnt work on Windows or the Iphone.
I have Linksys with DD-WRT with ports 500, 5500, 1701 (UDP/TCP to be safe) and I even put the Astaro appliance in DMZ mode to test. The connection starts but I get :
cannot respond to ipsec sa request because no connection is known ....
quickmode I1 message in unacceptable because it is uses a previously used message ID ...
Any ideas?
