Simple Port Forwarding

I have read through the user guides on port forwarding and the forum topics regarding it the I have located, but I am still having difficulty in setting up simple port forwarding.

Router: CRS125-24G-1s-2HnD
RouterOS Version: 6.7

Simple Port Forwarding Needed:
Internal IP Subnet: 172.16.1.136/29
1st Connection Type: tcp, port: 60803
2nd Connection Type: udp, port: 7594
External IP: variable/unknown

I am trying to learn how to do this both for my own home network, and for the company I work for (Wireless Internet Service Provider). We have started to deploy Mikrotik Routers for our customers (as managed routers) and simple port forwarding is becoming a problem.

ok at this hopefully that helps
