Access from LAN to LAN resource with port redirection via public address

RouterOS General
1

Hi,
This topic was discussed but I cannot configure access from LAN to another LAN resurce, with port redirected, via public address.
Example: I have a sever accessible from internet e.g. 85.89.169.20:123.
In the LAN it is 10.10.0.27. So, I defined NAT rule and it works perfect. From outside of LAN.
Question is how to configure RouterOS (and where) to get access e.g. from 10.10.0.20 to 85.89.169.20:123.

Thanks in advance!
M.

You want thing called hairpin NAT, see https://forum.mikrotik.com/viewtopic.php?t=179343.

TL;DR:

/ip firewall nat
add chain=srcnat action=masquerade dst-address=10.10.0.0/?? src-address=10.10.0.0/??

where ?? is subnet mask you use.
