What do you mean with firewall function?
In general firewalling is not really the job of a proxy. It just forwards packets it receives to somewhere else. In general a proxy would listen on very few ports.

Furthermore since this is a dockerized application it does not have access to the hosts networking, and can only work inside the container.

You could use the Stream function as a rudimentary firewall, disabling ports to block them? However I agree with Chaptergy, that's not really what this is designed for. For firewalls, it's best to use something like IPTables, and then a management service like UFW or easywall, rather than a Docker container.

So I agree too, this is quite out of this project's goal.
I did try to use ufw but due to docker messing with iptables it is not effective.

Instead I suggest OP or anyone interested to use the firewall feature your service provider, digital ocean or linode or whatever provides, set one up there. And it would be the same as putting a router in front of your network, creating a LAN and therefore protected.

Please do let me know if this isn't the best way of handling things or might pose security problems.

I'm closing this issue as a wontfix, as this is really out of scope.
