Hello, I'm trying to expose a TCP port on my single-node cluster (exposing a redis server) but I'm struggling to do do using IngressRouteTCP. I managed to add a custom entryPoint to traefik static conf and apprently, from traefik dashboard, router is ok and pointing to the correct svc. However, the port (6379) is still closed from outside (I can't see any iptables rule opening that for outside connections either). May I ask if someone can point me to a stright doc on how to open a TCP port on a freshly installed K3S cluster?
