Security and firewall ..

Post by jcdale »

What is the recommended security/firewall that would be capable of doing port forwarding?

Sincerely,

John

Generally speaking, port forwarding is something that you do in your router that connects to the internet, in order to allow an external program to connect to a server running in your home (or more generally, on the LAN). Do you know what kind of router you have?

Greetings! I have this working with NAT from my router now. That said, I'm writing a load balancer firewall using the Pi 4. I don't want to run my processes as root, and I'd like to to have some other options regarding ipTables. So, forwarding from 443 to 8443 on the same machine is a good way to handle this since networking can listen on privileged ports.

Since I want to use other features of the firewall and link up with CFS, I don't want to install a process whose sole job is forwarding. I'm also not keen to run my processes as root, then hand-off to another user as per.

Is there a known issue with ipTables forwarding on the pi?

Sincerely,

John
