Dear,
I am a beginner in the mikrotik configuration, result: Port forwarding to SSH server does not work in public internet! I'm doing something wrong because I've tried all instructions in the wiki for port forwarding, NAT and none works. Can you help with this problem? Asap please... 
Current setup:
Router IP: 192.168.5.254
Local network (ether2): 192.168.5.0/24
Public IP/port: 100.XXX.XXX.XXX:1992
SSH Server/port: 192.168.5.250:1992
