Hello,

I have a dedicated server where Proxmox is running in a VM (OPNsense). There I configured Wireguard (including site to site (to site)). All LAN devices from all LANs reach each other vice versa. So far, so goof. I can also reach the Proxmox host at its LAN IP from the Proxmox LAN. Unfortunately, I can't reach the Proxmox host from the remote LAN devices at its LAN IP.

I assume, this could have something to do with the settings regarding the standard gateway. I may be totally wrong, though.

I configured two bridges (one for WAN, one for LAN). I set the external gateway on the WAN bridge. Therefore, I can't set a gateway on the LAN bridge additionally.

I use an additional IP to reach OPNsense from outside (WAN).

How can I achieve to reach the Proxmox host from the remote LAN?
Should/may I remove entries from the WAN bridge settings and do I have to set the local gateway on the LAN bridge?

I hope, I could describe the issue clearly enough.
