Dynamic DNS clients
I want to know how do auto check and fix update when DynDns has no normal update?
sometimes DynDns client has no auto update ip.
If your WAN does not directly have the public IP, and so pfSense does not always realise if the public IP has changed, then the cron job that does a daily check will need to run more often. Install the cron package, then edit the "/etc/rc.dyndns.update" job to run more often. I have ISPs that like to reassign IPs multiple times a day, so I schedule this for every 5 minutes. That way a new public IP address is re-learnt after just 5 minutes or so and my OpenVPN links can find their end-points again.
my WAN has directly public IP. about one day change once IP. PFsense sometime can't normal update.
