Using PBR to Route Traffic on OpenWrt (fernvenue.com)
Playing around with OpenWrt often involves multiple outbounds, maybe multiple ISPs or VPN outbounds like WireGuard. We always need to configure and route the traffic. Configuring routing can actually be a headache because as the needs become more complex, the difficulty of configuration tends to increase exponentially, also considering potential conflicts. Using ipset is certainly good, but the workload doesn’t diminish, it becomes greater sometimes.
Postgres as a Graph Database: (Ab)Using PgRouting (supabase.com)
pgRouting is a Postgres extension. It's often used for finding the “shortest path” between two locations, however it's a hidden gem in Postgres and can be used for basic graph functionality.
Linux Routing Fundamentals (sdn.clinic)
Linux has been a first class networking citizen for quite a long time now. Every box running a Linux kernel out of the box has at least three routing tables and is supporting multiple mechanisms for advanced routing features from policy based routing (PBR), to VRFs(-lite), and network namespaces (NetNS). Each of these provide different levels or separation and features, with PBR being the oldest one and VRFs the most recent addition (starting with Kernel 4.3).
