RB750/750G - Port Forward Setting

Documentation links:

From MikroTik: http://wiki.mikrotik.com/wiki/Forwarding_a_port_to_an_internal_IP 

This setup seem to work well for me, however there are so many other features which I'm still not familiar with.
Appreciate those MikroTik guru or anyone who is familiar in this aspect can advise/comment to further improve this article and help beginner like me, kindly email : kingmeo786@gmail.com

Go to IP --> Firewall

If have a lot of port forwarding rules, may consider codes entry, just open Terminal window and enter codes according to the following pattern.

Port forward without external fix IP (most commonly use):

/ip firewall nat add chain=dstnat protocol=tcp dst-port=12345 \ action=dst-nat to-addresses=yyy.yyy.yyy.yyy to-ports=12345

Port forward with external fix IP:

/ip firewall nat add chain=dstnat dst-address=xxx.xxx.xxx.xxx protocol=tcp dst-port=12345 \ action=dst-nat to-addresses=yyy.yyy.yyy.yyy to-ports=12345

where:

12345 = is your desire port number
xxx.xxx.xxx.xxx = external fix IP
yyy.yyy.yyy.yyy = local IP (eg, 192.168.88.20)
