Currently, I have installed PVE (Proxmox Virtual Environment) on a PC with the management address set to 192.168.3.254:8006. Additionally, I have installed a virtual machine running OpenWRT (192.168.3.253). However, I'm unable to access the PVE management address from the external network. I have set up port forwarding on my physical router for both PVE and OpenWRT, mapping port 80 and 8006 to 30000 and 30001, respectively. Despite this, I find that I can't access the PVE management interface using http/https:external IP:30001, but I can access the OpenWRT management interface using http/https:external IP:30000. I've turned off all firewalls on PVE, but this hasn’t resolved the issue. Please help, thank you.
