Hi,
I decided to move my servers from all running on the main NIC of my Proxmox server, to run on a virtual network, behind a pfsense router.
(bad drawing attached bellow)
When i have the server behind the Pfsense router, it seems that the connection keeps dropping for some reason.
But i can SSH to the server without any issues. which is also routed via the pfsense. and i can ping my laptop from the syncthing server.
Logs from my clients:
