Multi WAN 22.05 Dynamic DNS not updating when primary link goes down
0%
Description
When using gateway group with failover, dynamic DNS is not updating when the primary link goes down.
Gateway status shows Pending, and gateway group shows Gathering data for that gateway.
Device: SG-3100
Firmware: 22.05
WAN_DHCP: Tier 1 (bridged)
OI_FIBRA_DHCP: Tier 2 (behind a NAT)
Gateway group:: Net_Oi
Firewall default gateway: Net_Oi
Dyndns: Duckdns
Interface to monitor: Net_Oi
Interface to send update from: Net_Oi
Unplug the cable from the primary WAN:
As we can see below, dyndns is not triggered.

Now, we can see dyndns being triggered.

Changed the gateway Oi_Fibra from DHCP to static, and it is working now
Updated by Danilo Zrenjanin over 2 years ago
- Status changed from New to Confirmed
Tested on SG-3100 running on:
22.05-RELEASE (arm) built on Wed Jun 22 18:56:40 UTC 2022 FreeBSD 12.3-STABLE
I was able to reproduce the same behavior.
Dynamic DNS doesn't recognize the link down on the tier1 WAN gateway in a gateway group (if it's assigned by a DHCP server). If it's defined manually, Dynamic DNS gets updated as expected.
