New blog post: Running your own Autonomous System on FreeBSD.
Got an AS number and IPv6 /48 via RIPE, set up a FreeBSD BGP router with FRR, two upstreams, and built GRE/GIF tunnels ti bring my own globally routable addresses to servers at different providers.
The interesting part: dual-FIB policy routing lets FreeBSD jails speak from both provider and BGP addresses simultaneously.

@Larvitz great great post!
The BGP article is also available on the Geminispace for those who prefer the lightweight web:

No tracking, no JavaScript, just text. Accessible via clients like Lagrange or Amfora.
@Larvitz Dual-FIB is such an elegant way to handle this. Bringing your own IP space is truly the endgame of self-hosting. Nice work👍 👌
@cd_run_code It all was a slow escallation from the silly idea "What if I could be my own provider" to that result, I have now .. 🙂 But was an amazing learning opportinity!
@Larvitz Haha, exactly! Next step: laying your own fiber cables across the ocean to complete the ISP experience 😅
