That’s fine, I gave it what I wrote and asked it cross reference, it gave me something that didn’t make sense in my head, and since I can’t find a concrete answer with most people opting for DMZ/DHCP.
The newest post I was able to find (or most relevant) was Mikrotik Half Bridge PPPoE - #3 by Caci99
The link to the docs there does not work anymore and I was unable to find it in the new wiki, however I was able to find a backup https://www.coursehero.com/file/26700931/Manual-BCP-bridging-PPP-tunnel-bridging-MikroTik-Wikipdf/ (Edit: forgot to mention for anyone that comes across this in the future, that after checking the article it seems unrelated) as well as Bridging and Switching - RouterOS - MikroTik Documentation which is related.
There was another post as well, where someone got closer but then they took the conversation off the forum into DMs.
