Example of Destination NAT
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 talk with 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 talk 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
Example of 1:1 mapping
If you want to link Public IP subnet 11.11.11.0/24 to local one 2.2.2.0/24, you should use
destination address translation and source address translation features with action=netmap.
/ip firewall nat add chain=dstnat dst-address=11.11.11.1-11.11.11.254 \
action=netmap to-addresses=2.2.2.1-2.2.2.254
/ip firewall nat add chain=srcnat src-address=2.2.2.1-2.2.2.254 \
action=netmap to-addresses=11.11.11.1-11.11.11.254
