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.
Absolutely. But I at least realized it had to be asymmetric routing… because if I didn’t I would have been even more puzzled. Because even setting firewall rules wouldn’t fix it then. I’m glad there are people here that understand that sometimes we brain fart and they give you a great pointer! Like the second I saw netmask I knew what was wrong and facepalmed.
