You’d just treat Traefik like you would any other reverse proxy with AMP.
As long as you configure it correctly, it’ll work fine.

(Just adapt the Nginx examples to Traefik)
If you set up AMP’s automated HTTPS setup, you’ll obvi need to remove Nginx from the system before Traefik will work.
To rebind the ADS to 127.0.0.1 you’d run:
sudo su -l amp
ampinstmgr rebind ADS01 127.0.0.1 8080
Assuming it’s a standalone setup, you’d ignore the repairauth warning.
Do note, that you cannot reverse proxy TCP/UDP game traffic unless the game server supports something like HA Proxy or TLS.
