# 192.168.11.166 Routing Fix
|
|
|
|
**Date**: 2026-01-22
|
|
**Issue**: 192.168.11.166 not showing in UDM Pro because no traffic from this IP
|
|
|
|
---
|
|
|
|
## Root Cause
|
|
|
|
### Problem Identified
|
|
- **Default route**: Configured to use `eth0` (192.168.11.166)
|
|
- **Actual routing**: Uses `eth1` (192.168.11.167) for gateway
|
|
- **Result**: No traffic from 192.168.11.166 → UDM Pro doesn't see it
|
|
|
|
### Why This Happens
|
|
The kernel routing table shows:
|
|
```
|
|
default via 192.168.11.1 dev eth0
|
|
```
|
|
|
|
But when actually routing to 192.168.11.1:
|
|
```
|
|
192.168.11.1 dev eth1 src 192.168.11.167
|
|
```
|
|
|
|
The kernel prefers eth1 because it can actually reach the gateway, even though the default route says eth0.
|
|

|
## Solution
|
|
|
|
### Option 1: Fix Routing (Recommended)
|
|
Add explicit route for gateway via eth0:
|
|
```bash
|
|
ip route add 192.168.11.1 dev eth0
|
|
```
|
|
|
|
### Option 2: Generate Traffic
|
|
Force traffic from 192.168.11.166 to make UDM Pro see it:
|
|
```bash
|
|
ping -I 192.168.11.166 192.168.11.1
|
|
curl --interface 192.168.11.166 http://192.168.11.1
|
|
```
|
|
|
|
### Option 3: Remove Unused Interface
|
|
If 192.168.11.166 is not needed:
|
|
- Remove net0 from container
|
|
- Keep only net1 (192.168.11.167)
|
