DynDns not updated

mila76

I have an pfSense RC3 with two WAN. (but RC1 have the same issue)
Primary with lan connection to a router with fixed ip
Secondary PPPoE and dynamic ip.

I setup a dyndns on the PPPoE. All ok, dynamic work. But if PPPoE go down my dyndns.org is not updated.
pfSense try to update but in system log i have:


Jul 14 12:12:34 	php: : DynDns: updatedns() starting
Jul 14 12:12:34 	php: : DynDns debug information: xx.xx.xx.238 extracted from local system.
Jul 14 12:12:34 	php: : DynDns: Current WAN IP: xx.xx.x.238 Cached IP: xx.xx.xx.2
Jul 14 12:12:34 	php: : DynDns debug information: DynDns: cacheIP != wan_ip. Updating.
Jul 14 12:12:34 	php: : DynDns: DynDns _update() starting.
Jul 14 12:12:36 	php: : Gateways status could not be determined, considering all as up/active.
Jul 14 12:12:36 	php: : Message sent to xxx@xxx.xxx OK
Jul 14 12:13:49 	php: : DynDns: DynDns _checkStatus() starting.
Jul 14 12:13:49 	php: : DynDns: Current Service: dyndns
Jul 14 12:13:49 	php: : Curl error occurred: couldn't connect to host

To fix this situation i have to edit my dyndns conf and save.. pfSense restart updating and all work again.

I have no idea why not working.. but i think if a re-check if cacheIP != wan_ip after 1/2 min fix this issues
