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

Welcome to the Forum, David!
We'll try to help you :)
Please post (inside the CODE tags) the results of the commands:
dmesg | grep -i enp
ip a
ip route

And IP details from your laptop.
Also, to start from a simple setup: shutdown any VMs in the host, if there are any.
In case you have enabled the Proxmox firewall, disable it during the tests.
Are there any VLANs in your network?
Is there DHCP? If yes, what is the IP addresses range of DHCP?
