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:
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:
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)
Status
Fixing routing and generating traffic...
Next Step: Verify 192.168.11.166 appears in UDM Pro after traffic generation
