I bought a few old 10 gigabit NICs from eBay for use with my main PC (Windows 10) and home server (Ubuntu). I’m linking these computers together via the cards, so I won’t need a separate switch or router for internet traffic. Each machine gets its own IP—192.168.1.2 and 192.168.1.3—ensuring no conflict with my onboard LAN’s 10.0.0.x range. Both have a private subnet (255.255.255.252), no gateway, and no DNS settings. I can ping the server from my PC and vice versa, share folders on my PC to the server, but I can’t SSH into shared drives. Samba is set up to use both network interfaces on the server, yet I’m still getting a connection issue. When trying telnet or SSH, I see this error: “telnet: Unable to connect to remote host: Cannot assign requested address.” I’m new to networking and hope someone can help clarify what’s going wrong.

Your setup has a problem: the /30 subnet X.X.X.3 is set as the broadcast address for the X.X.X.0 network. It's better to use client addresses like .1 and .2 instead.

Ah yes this was it. As I mentioned before, I'm a networking noob. Appreciate the help!
