Solution was to ditch bridges and forcefully map the container's ports in extra parameters:
-p '192.168.1.41:80:80' -p '192.168.1.41:443:443'

However it is interesting to note that Unraid's UI mixes up the actual IP addresses, perhaps this is a bug, not sure:


ALSO (very important), uncheck the "enable default gateway" for the secondary interface because otherwise you will have an industrial quantity of asymmetric routing which will break your services.

Ahhh I see, thank you for letting me know.
Followed this tutorial which solved my problem:
