Easy Way to Automatically Forward Ports to VM's / LXC Containers

[bugattiguy527]

Hello! So I self-host several things across many VMs and LXC containers. The self-hosted projects need to be accessible from the internet and so my way of doing that was to use iptables to say anything on port 3000 will get directed to the IP of the LXC container that had the project on port 3000 that needs to be accessible from the internet. Unfortunately, it's annoying when I have to create many of these a day. I wrote a script to do this for me but I'm wondering if there is a better or easier way to do this (maybe even from inside the proxmox control panel). Does anyone know of a better way to direct ports to go to certain IPs? Or maybe have a similar way to how in a docker container you can set the network mode to host? Thanks!
