Hi I have some VMs using the built-in NAT function. I need to open some ports from the host into the VMs. Using built in PVE Firewall I've enabled Datacenter FW with Accept/Accept rules. I have enabled Host firewall, no rules. I've enabled VM firewall and these are the rules.[OPTIONS] enable: 1 dhcp: 0 [RULES] IN ACCEPT -p tcp -dport 40100 -sport 40100 But it is not working. Any suggestions, this is the last hurdle to overcome then I'm all set to replace VirtualBox with Proxmox.
