@madcaesar @otl It’s a small server running OpenBSD, configured to operate as a router and/or firewall.
Linux and the *BSDs can operate as very good routers and firewalls, usually being much more configurable and enabling you to do more complex than off-the-shelf consumer-level hardware routers. Using them on a small form factor computer with a cheap switch in front of them can give you a better performing and nicer to use alternative.
@refalo @yogthos China has a single CPU manufacturer with an x86 licence, Zhaoxin. Their offerings don’t rival AMD or Intel upper end, but they’ve been around for ages and are widely used in China.
