One is the route from my Proxmox (vimes) server to my NAS, (colon) going via my Router (pessimal) (as it should be) Second one is my NAS going to Proxmox directly. However I didn’t set any static routes and this is causing issues as the Router Firewalls those Asymmetric Connections. This is happening since I upgraded Proxmox… I am not the best at network stuff, so if someone has some pointers I’d be most grateful.

I’m a moron and had a wrong subnet mask.

this, most likely a netmask mismatch.

Make sure all 3 devices have a /24 (255.255.255.0) network mask

Most of what I know is on the job learning, I dont have any certificates in any of what I do.
