Basic NAT configuration problem

RouterOS Beginner Basics
1

I am new to Mircotik.
using routerOS 5.2
license level 4.

I cannot get a NAT session set up.
I’m using the web-gui.
Ip-> Firewall-> NAT

Built a nat rule
chain = dstnat
src address = 192.168.88.241 … my local server
dst addrss = 71.70.229.254 … my public ip
protocol = 6 (tcp)
src port = 80
dst port = 80

That’s all.

Every time I try and access 71.70.229.254 it takes me to the routers home page, instead of forwarding to my server.

Any idea what I’m doing wrong.. thanks.

The inbuilt web server of Mikrotik ROS runs on port 80 by default. To achieve your desire, you either change the mikrotik default www port from 80 to something else, i.e. 8080, or change the dst-nat port from port 80 to 8080.

To implement the first option, goto ip->service->www and change 80 to 8080. Now the mikrotik web-gui can only be accessed on 71.70.229.254:8080 while you local web server will be accessible at 71.70.229.254

To implement the second option, change the dst-port of your NAT rule from 80 to 8080. Now your local web server will be accessible at 71.70.229.254:8080 while the mikrotik web-gui will be accessible at 71.70.229.254

remove the src-address. put it in the to-addresses field.
