[SOLVED] Error checking subscription: Connection Failed: Connect error: Network is unreachable (os error 101) (500)

[arcticwarrior]

Hello All,

I want to start by saying that I'm a newbie using Proxmox VE. I'm trying to do a setup using a NUC with dual NICs, both of them connected directly to the ISP router.
I want to have a VM with pFsense as a FW. So far, I have installed only, and it is not being configured yet. I don't want to move forward until I get the basics right.
Being said that I have this error while trying to check subscription status


This started when I changed the network configurations so I'm sure I did something wrong.

Here is my actual network configuration:


Any help will be very much appreciated.

NOTE: I had to install Debian 11 and Proxmox VE on top of it since my processor was not working properly with the ISO 7.3.1

1. Do not give two interfaces an IP in the same subnet.
2. One of your interfaces needs a gateway. (Currently, either vmbr0 or vmbr1; depending on point 1.)
3. Interfaces with an static IP have to be: static instead of: manual.

Edit: Better stay with the IP for PVE, that is in: /etc/hosts. Those have to be in sync anytime.

Edit2: Be careful to not lock yourself out. Better have local-/IPMI-access!

See here as an example, how the default bridge config looks like:

Thanks a lot for your help. That helped me. I got the network cards working now. Now I need to learn how to configure pFsense correctly for my needs.
