PM VE on Minisforum HX90 issues

[mylesw]

So received a new Minisforum HX90 box with 4TB disk, 64GB memory, Ryzen, etc. and attempted to install PM 7.1 on it. Fail.

For some reason, it would not detect the inbuilt 2.5Gb/s NIC, so I tried with a USB connected Ethernet adapter and it kinda worked. But then discovered that I could install Debian first, and then PM VE on top of it. Did that, and the inbuilt NIC worked!

Thought I was out of the woods, but although I can SSH to the host and ping my network from it, resolve DNS, etc. when I install a VM on the box, the VM cannot get out past the host. My network installation is basic - just the network adapter, vmbr0 to it, with IP4 assigned values, and I'm duplicating another server I have working just great on my network. But this box will not let the TCP out of the VM.

Checked that all firewalls are disabled. They are. Checked the host and it is fine - pings out just great, resolves, etc. Again, no VMs are able to bridge to it though.

Interestingly, the VMs can ping the host IP address. But can never get to the gateway - the gateway that the host itself can get to. Anything other than the host IP is off limits to the VMs.

I've never had this issue before, but then I've never had to install Debian first, and then PM VE on top of it.

Anyone got any ideas where to check on this?

Here's some basic ref data for my installation:

/etc/network/interfaces. on the host

source /etc/network/interfaces.d/*

auto lo
iface lo inet loopback

auto eno1
iface eno1 inet manual

iface enx00249b68ea1d inet dhcp

auto vmbr0
iface vmbr0 inet static
    address 192.168.175.38/24
    gateway 192.168.175.1
    bridge-ports eno1
    bridge-stp off
    bridge-fd 0
