0%
Description
pfSense 2.7.2, all patches applied.
DYNDNS provider -> DUCKDNS
Default gateway of the firewall is a Gateway group in which WAN1 is the primary (TIER 1) and WAN2 is the backup (TIER2).
Firewall State Policy is set to Interface Bound States
DYNDNS configuration:
Interface to monitor: WAN2
Interface to send update from: WAN2
What is happening:
WAN1 IP address is being updated for the DYNDNS.
What should happen:
WAN2 IP address should be updated for the DYNDNS.
What actions I did to fix the issue ?
Changed Firewall State Policy is set to Interface Bound States to Floating States.
This fixed the issue.

Hello Marcos, thanks for answering.
I'll try to simulate that in my lab, I'll install a new NIC in my server to map that with libvirt.
But I can't do it right now, too busy lately unfortunately.
As soon as I have some free time, I'll test and update here.
Thanks.

Hello, my ticket #16716 has been closed as a duplicate of this one. It seems this is indeed the same problem, except I haven't meddled with this "Firewall State Policy" setting for now.
Considering this problem is still happening on pfSense Plus 25.11.1, I think you can change this ticket back as not resolved.
Of course if you need to do some tests, I can do that.
