As I understood, when LiveKit server is deployed on kubernetes it's attached to host network and we don't have to deal with ports like 50000-60000 and just few ports are configured in service that ingress or other internal services can talk to LiveKit server. Please correct me if I'm wrong. Now it's my task on server to decide which ports I have to leave opened and which closed. For example 7880 I have to close and I can configure ingress with domain name and 443 port to talk to LiveKit serve, which means other external services can only talk to LiveKit signaling part over 443 port + leave opened 50000 - 60000 port range

you could configure it to just use a single port. we typically set it to

rtc.udp_port: 7882

to use single port mode

Instead of using range or ports ?
