**From now on, connect via Tailscale:** `ssh ubuntu@clawdbot` (or use the Tailscale IP).
## 5) Lock Down VCN Security
Now that Tailscale is running, lock down the VCN to block all traffic except Tailscale. OCI's Virtual Cloud Network acts as a firewall at the network edge — traffic is blocked before it reaches your instance.
1. Go to **Networking → Virtual Cloud Networks** in the OCI Console
2. Click your VCN → **Security Lists** → Default Security List
3. **Remove** all ingress rules except:
- `0.0.0.0/0 UDP 41641` (Tailscale)
4. Keep default egress rules (allow all outbound)
This blocks SSH on port 22, HTTP, HTTPS, and everything else at the network edge. You'll only be able to connect via Tailscale from now on.

## Security: Why VCN + Tailscale Is Enough
With the VCN configured as above (only UDP 41641 open), you have **defense in depth** that makes traditional VPS hardening redundant.
With the VCN locked down (only UDP 41641 open), you have **defense in depth** that makes traditional VPS hardening redundant.
**How it works:** The VCN blocks traffic at the network edge — before it reaches your instance. Combined with Tailscale SSH (which bypasses sshd entirely), there's no attack surface for typical threats.
