Do I really need a firewall for my server? (sopuli.xyz)

I've been running my server without a firewall for quite some time now, I have a piped instance and snikket running on it. I've been meaning to get UFW on it but I've been too lazy to do so. Is it a necessary thing that I need to have or it's a huge security vulnerability? I can only SSH my server from only my local network and must use a VPN if I wanna SSH in outside so I'd say my server's pretty secure but not the furthest I could take it. Opinions please?

Interesting, I haven't noticed anything, in fact since I switched everything has felt faster. And I'm constantly sending large files to devices on other VLANs.

    It will be slower with more latency and CPU usage.

    I would highly recommend you read up on networking and the OSI model. Switching is extremely fast because it is done in hardware. Routing is slow because it goes though the CPU.

    If all else fails you could create a dedicated vlan for storage access.
