Pfsense with USB 3 to Ethernet setup
Pfsense with USB 3 to Ethernet setup
You're exploring an unconventional idea—repurposing an old laptop as a PFSense router. The single port limitation is a challenge, but USB 3 to Ethernet adapters can sometimes bridge the gap. These devices are often built for continuous operation and may handle the load better than standard peripherals. Other possibilities include checking if your laptop has additional ports or considering a more robust setup like a dedicated router with multiple interfaces.
AFAIK very few systems run AFAIK. FreeBSD offers limited USB device support. The situation can be uncertain with pfSense since it requires consistent network interfaces after reboots; using a USB adapter might cause unexpected disconnections or port changes, leading to boot failures. It's not the best choice for continuous operation. I tried OpenWRT on a PC with a USB adapter and experienced random crashes, though another worked well and I currently use a 5Gbit adapter on Linux running 24/7. It's possible to get it to work, but you need to identify compatible chipsets and watch out for issues.
