Dear Proxmox people,
My apologies if the topic was already discussed… I'm not so vell-versed in networking questions and might not know what to search for.
I have configured an SDN, exactly as described here: https://pve.proxmox.com/wiki/Setup_Simple_Zone_With_SNAT_and_DHCP — the setup describes my desired use-case exactly.
These instructions were used to set up two PVEs in different networks, identical fresh install of version 9.1.6 on both. One is located in a basic lab network behind a consumer router. Everything works wonderfully as expected: containers assigned the self-made VNet as a bridge get internal IP addresses in the range 10.0.0.2-10.0.0.253, assigned via DHCP. The other PVE host is run in a DMZ. When I assign the VNet to a container as a bridge there, the container won't start at all. The error message is not very enlightening:
When assigned the standard
As said, the exact same config in the lab network works just fine. I'm a bit lost about what to do or where to search for more information.
The host's
Both hosts run tailscale, and logging in and accessing the web interface via the tailscale VPN service are no issue at all.
I'd be grateful for any help…
