Hello,

New here, new to Proxmox, experienced in Vmware and cloud platforms, all of them.
'
The install works, I guess I should mention my irregular setup:

Portwell CAR-3040 server (formerly a Sophos SG210) 4th generation Intel Core i7/i5/i3 (Haswell) CPU, Intel H81/B85 chipset with 16GB RAM and a Samsung 870 500GB SSD.

The Portwell is a 1U network type server with 6 onboard Intel Ethernet controller: Intel Corporation I210 Gigabit Network Connection (rev 03) ports.

These ports are viewed as:
enp2s0
enp3s0
enp4s0
enp5s0
enp6s0
enp7s0

Note: I had a 4 port 10GBe card I have since removed to simplify)

/etc/network/interfaces:

auto lo
iface lo inet loopback

iface enp6s0 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.100.2/24
gateway 192.168.100.1
bridge-ports enp6s0
bridge-stp off
bridge-fd 0

iface enp6s0 inet manual
iface enp7s0 inet manual
iface enp2s0 inet manual
iface enp3s0 inet manual
iface enp4s0 inet manual
iface enp5s0 inet manual

So I can get the interface to come up and show an IP, but I cannot ping Google, I cannot ping the host from a laptop on the same network, and I cannot ping the laptop from the host console.

Thus far I tried the PROMISC mode for the VMBR0, didn't work.

Not sure what I am doing wrong, and I really don't want to have to pay before I can confirm this will even work?

My end result:
2 VM's, one will be OpenWRT to connect to Speedify, and the other will be the Ubiquiti Controller for my Wi-Fi 7 mesh, if this ever gets going.

I have used Linux since 1991, though lately I have been more into policy writing and audit vs hands on, but I can still use the VI editor with the best of them! For hardware, my grad level EE from state school, I did board level design after college and I can solder, including surface level, with the best of them too! Some skills never die I guess?

So any help is appreciated, I am open to trying anything, this is a lab setup to test the viability of Proxmox vs ESXi. Little sad I could not get this going on the network and I had to eat crow and come here for help, but what else could I do? Yes, I have RTMF several times over, nothing I tried worked.

Thanks,

David P. Howard
