Is there a way to portforward the amp panel with at&t portforwarding so i can mange my servers game and files?

my server is a old pc running ubuntu and hosts my Minecraft Bedrock Edition server and its using playit.gg to be able to share the world with my friends (i did this by following a tutorial on Youtube) but now i wanna be able to access my AMP panel from where ever i go, after viewing a couple of guides and gaining access to my router i came across a problem, you cant put an Ip address only “Global Port Range” and “Base Host Port”, since i dont wanna go through hell and coming across dead end i deiced to come here for help since i have very little experience and basically my first time host a home dedicated server, so is there a way to port forward the AMP panel on at&t port forwarding panel
