Linux split-tunnel and policy routing: ip rule, fwmark, WAN, awg0, default via VPN, nft masquerade, rp_filter, conntrack. Not OpenWrt, not podkop, not UCI. Triggers: split-tunnel, ip rule, fwmark, multiple default, rt_tables, source-based routing, маршрутизация, таблица маршрутов, раздельный туннель.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Linux Routing Skill for routing and NAT on a Linux host (iproute2 + nftables). Write `ip`/`nft` commands that can be pasted into a console or a unit. Do not use it for: - OpenWrt + podkop/sing-box → `podkop-openwrt-guide` - zapret DPI → `zapret-openwrt-guide` - Docker bridge overlay as the main subject → `docker-ops` - Amnezia keys/handshake → `amnezia-vpn`; only OS routes/NAT belong here ## When to use - Two default routes, VPN + WAN, split-tunnel. - `ip rule`, tables, fwmark, source-based routing. - NAT/masquerade, port forward, conntrack. - A packet goes into the VPN and the reply never comes back; asymmetric routing. - WireGuard/AWG `AllowedIPs` vs `ip route`. ## Workflow 1. Capture the picture: `ip -br addr`, `ip route`, `ip rule`, `nft list ruleset`. 2. Separate L3 (route/rule) from L4 NAT (nft) and from firewall drops. 3. Change one table/rule at a time. Never blindly delete the default route in main. 4. Check with `ip route get <dst> from <src> iif <if> mark <hex>`. 5. Persistence: `/etc/iproute2/rt_tables`, netplan/NM dispatcher, nftables.conf — not "commands in the SSH history". ## Quick snapshot ```bash ip -br addr ip route show table all ip rule show …

How to install
mdr add nordz0r/skills/linux-routing@sha256:d1f2cbedb92a6a9cThe line at the top of this page pins the label git:20261013.df0a08f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
