## Network Configuration
|
|
|
|
- **LAN IP**: `192.168.0.81/24` (DHCP from home router)
|
|
- **Tailscale IP**: `100.64.0.2` (Headscale node 20)
|
|
- **Default gateway**: `192.168.0.1`
|
|
|
|
### Tailscale / Headscale
|
|
|
|
Joined to Headscale at `headscale.vish.gg:8443`. Accepts all subnet routes (`--accept-routes`).
|
|
|
|
**Known routing quirk**: Calypso advertises `192.168.0.0/24` as a subnet route via Headscale. This causes Tailscale to install that route in table 52 on this VM, which breaks inbound LAN connectivity (replies go via `tailscale0` instead of `ens3`). Fixed with a persistent ip rule:
|
|
|
|
```bash
|
|
# /etc/network/if-up.d/99-lan-routing-fix
|
|
ip rule add to 192.168.0.0/24 priority 5200 lookup main 2>/dev/null || true
|
|
```
|
|
|
|
This rule takes priority 5200, beating Tailscale's table 52 rule at 5270.
