Loopback NAT Not working

Mon Dec 06, 2021 2:33 am

Hello,

I tried following this tutorial to implement loopback NAT: https://www.youtube.com/watch?v=_kw_bQyX-3U&t=257s

While I can access my port forward on external networks, it does not work internally.

Could someone maybe take a look at this config and tell me what I am doing wrong? I've looked for a way to share my configuration but I cannot find it.

Here is an image of my NAT table, any advice would be much appreciated. I see this on the wiki: https://help.mikrotik.com/docs/display/ ... HairpinNAT

But maybe I am not sure what to put in as my src-address?

/ip firewall nat
add action=masquerade chain=srcnat dst-address=10.0.0.3 out-interface=LAN protocol=tcp src-address=10.0.0.0/24

The problem is dstnat rules having in-interface=ether1. For more info see viewtopic.php?t=179343
