Run it when port 80 is blocked

[phit42]

Hi, I've tried your docker container as it includes a proxyDHCP.
Unfortunately port 80 on my server is in use, thus I need to ask nginx to listen somewhere different, or else I am getting hundreds of those:
Connection to localhost (::1) 80 port [tcp/http] succeeded!
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address in use)
linuxserver/docker-netboot.xyz⁠ provides an optional env variable NGINX_PORT that would allow to change it, but it appears as if your container setup ignores said variable or does not hand it thru correctly to nginx?
