New router, PVE host can't connect to network at all

[siren4161]

First let me say I know this is a common issue and I've scoured this forum and Google for advice. I recently moved homes and had to return my AT&T router. Anticipating this issue, I took screenshots of my router configuration. I haven't purchased my ultimate new router yet, but in the meantime have tried to wire my PVE host directly to a Spectrum-provided router and an old Netgear router and in both cases it won't show up as a connected device at all.

My PVE host has always been configured with static IP 192.168.1.165, and both new routers used the 192.168.1.X range by default. The LAN port LEDs on the routers and the PVE host indicate a good connection, but the router config pages don't show PVE as a connected device and I cannot ping anything, including the router's IP, from PVE. I have tried multiple ethernet cables.

Attachments:

1. Old router configuration page
2. New router configuration page
3. /etc/network/interfaces
4. /etc/hosts
5. /etc/resolv.conf

I would be forever grateful if someone can point out what I might be doing wrong.

Good morning, you have a firewall on the new router and so you must deactivate this Firewall to get the new IP 165 working on your device.

Hello, I'm not seeing any firewall in the router settings. There is an Access Control page that can block certain devices, but the router was freshly factory reset and is not set to block anything.

During installation you were asked for Hostname(FQDN), IP address, Netmask, Gateway and DNS Server. The values you enter must fit to your local network. You can not simply wish to use a random IP address like 1.1.1.1 ;-)

Assumptions for the following details:

• you use the Internet Protocol Version 4 in a home setup behind a normal router/gateway
• your PVE setup is very basic, without bells or whistles: one physical NIC and one logical bridge "vmbr0"
• you use a wired connection, WLAN is basically not...

Please call on the proxmox ve root console:

ip addr show
ip route show
ethtool <device name> # <device name> is something like eth[0-9]+, enp[0-9]+s or eno[0-9]+, see 1st results
#on new installations mybe other names

have you changed or replaced your Ethernet cable with a new one?

Some times its the router port it selves the Problem.
Please check: put a simple non management 5 or 8 Port 1 GBit/s Switch between your router and your proxmox ve host.
