Description
I have ix0 parent interface with 3 VLANs, one for each ISP: 10 (WAN), 20 (WAN2) and 30 (WAN3).
All ISPs use DHCP to assign IP addresses.
The issue is that pfSense often sends DHCP requests through the wrong interface.
For example, it sends packets from WAN2 IP address to WAN2's gateway, but using WAN interface (confirmed by doing packet capture both on the ix0.10 and on ix0 with VLAN 10).
Naturally, this causes DHCP issues on top of other unresolved DHCP client bugs I have been struggling with over the years.
