My post says "My firewall blocks all inbound traffic". The login error 
messages do not say it on port 22. That inbound port is blocked by the 
firewall. All pc on the lan are powered off. Even disconnected the lan 
cable from the freebsd gateway host and still the error messages come 
out. That is why I am asking for help here.
