I have pihole running on my unraid server. I was looking to install Heimdall too, but that also wants to use ports 80/443, which pihole already uses. How do I go about running heimdall? Do I just pick different ports randomly for it to utilize? Is there a way for them to 'share' the port? Some other solution?

Cursory googling is telling me that I should either assign Heimdall other ports, such as 81/444, or I could use something like nginx/traefik to basically allow both to coexist and forward their traffic through it?

Although I believe both of those expose me toward the internet, which will introduce its own set of headaches? Right now I'm not trying to host anything that requires an external connection - this is purely for my own LAN.
