Ok, apparently I am exceedingly dense. I cannot get l2tp/ipsec vpn
working on Mikrotik. The RB has been configured as the server. I
have tried with mac vpn client and Windows vpn client and cannot get
a connection. pptp works fine. Can someone give me a pointer
here.Here are the logs, numbers have been changed of course.
