+### Port Forwarding (router → Juris)
+
+| External Port | Internal | Service |
+|--------------|----------|---------|
+| 443 | → LXD proxy → xray container | Xray VPN (VLESS+XHTTP+Reality) |
+| 16627 | → LXD proxy → xray container | x-ui admin panel |
+| 22 | 22 | SSH |
+
+## LXD
+
+LXD manages the `xray` container. The host forwards ports 443 and 16627 into the container via LXD proxy devices.
+
+### Storage pool
+
+| Name | Driver | Source |
+|------|--------|--------|
+| `default` | dir | `/var/snap/lxd/common/lxd/storage-pools/default` |
+
+### Network
+
+| Name | Type | Subnet |
+|------|------|--------|
+| `lxdbr0` | bridge (managed) | `10.187.159.1/24` |
+
+### Container: xray
+
+| Setting | Value |
+|---------|-------|
+| Image | Ubuntu 24.04 LTS (noble), amd64 |
+| IP | `10.187.159.41` (via `lxdbr0`) |
+| State | RUNNING |
+| Profile | default |
+
+**Proxy devices** (host → container):
+
+| Device | Listen | Connect |
+|--------|--------|---------|
+| `proxy-443` | `tcp:0.0.0.0:443` | `tcp:127.0.0.1:443` |
+| `proxy-16627` | `tcp:0.0.0.0:16627` | `tcp:127.0.0.1:16627` |
+
+**Services inside xray container**:
+
+| Service | Description |
+|---------|-------------|
+| `x-ui` | Xray panel — manages Xray config and inbounds |
+| Xray (via x-ui) | VLESS+XHTTP+Reality inbound on port 443 |
+
+### Useful commands
+
+```bash
+# Enter xray container
+lxc exec xray -- bash
+
+# Check xray config
+lxc exec xray -- cat /usr/local/x-ui/bin/config.json
+
+# Restart x-ui (and xray)
+lxc exec xray -- systemctl restart x-ui
+
+# View x-ui logs
+lxc exec xray -- journalctl -u x-ui -f
+```
