Auto DHCP Renew not working on WAN (How to fix it), updated script
This solved my problems when WAN connection goes down if ISP changes something at their end. Updated it a little more. I want to know when connection has had a hick-up so I know why example VPN connections go down. Notification email is being sent using pfSense notification settings (does not leave if it gets rebooted. Then you get bootup complete notification from pfSense itself). Date and time is written to logfile with finnish date and time format.
You can find the original script here http://forum.pfsense.org/index.php/topic,17243.0.html
For those of you who are nix handicapped like me, installing and activating this script is easy to do via the web interface.
Go to Diagnostics > Edit file
Cut & paste the code below, editing the user variables to match your settings.
Save the file as /usr/local/bin/pingtest.sh (or path/name of your choosing)
Go to Diagnostics > Command
Execute the command "chmod +x /usr/local/bin/pingtest.sh" (makes the file executable)
Go to System > Packages and install the Cron package
Go to Services > Cron
Install a new cron with settings "/5 * * * * root /usr/local/bin/pingtest.sh" (runs test every 5 minutes)
If you want to verify the test is running, uncomment (remove the "#") in front the "echo" commands on lines 42, 46 & 47. Then, use Diagnostics > Edit file to view the contents of /root/pingtest.log. There should be a log entry every 5 minutes. Once you're sure it's running, be sure to add the comments back so you don't fill your hard drive with this script's status message.

ok so ive followed this script.
For some reason, if i manually put the WAN down. It still pings google.com etc
but i cant access internet.
and gateway shows wan interface as down also.
how do i fix this?
Below is the log of ping even though wan is down.
09.10.2020 11:01:00 Pinging google.com
09.10.2020 11:01:00 Ping google.com OK.
You uncommented the diag lines and checked the log file like it says?
What does it show?
