@andyrh said in New 7100 setup:
I moved the WAN by changing the parent interface for the default WAN VLAN.
The VLAN on WAN, 4090 by default, only applies to the internal switch. So simply moving the VLAN parent to ix0 or igb3 would only work if VLAN 4090 is defined correctly on the external switch they are connected to.
If that's not the case the new WAN interface would be directly ix0 or igb3 without a VLAN.
