Access from remote network not from local network

RouterOS Beginner Basics
1

Hi All,

I am having a problem.
I am testing a webserver, so i have setup a domain name that points to my external IP address.
I forwarded port 80 also from external network it works great, and webserver is accessable.
But when i am on the the internal network i cannot acces the webserver with this domain.
When i type the local IP from in the internal networks it also is working.
How can i access this domain with the domainname from in the internal network?

I am using RouterOS v6.43.8

This is an export of my settings.
What am i missing or doing wrong??

Any help would be great!!

Try accessing the external domain name from another subnet (not the subnet the server is on).
In general the functionality you are looking for is called hairpin nat.

Forward all traffic to internal host
If you want to link Public IP 10.5.8.200 address to Local one 192.168.0.109, you should use destination address translation feature of the MikroTik router. Also if you want allow Local server to initiate connections to outside with given Public IP you should use source address translation, too.

Add Public IP to Public interface:

/ip address add address=10.5.8.200/32 interface=Public
Add rule allowing access to the internal server from external networks:

/ip firewall nat add chain=dstnat dst-address=10.5.8.200 action=dst-nat
to-addresses=192.168.0.109
Add rule allowing the internal server to initate connections to the outer networks having its source address translated to 10.5.8.200:

/ip firewall nat add chain=srcnat src-address=192.168.0.109 action=src-nat
to-addresses=10.5.8.200
