Randomly can't ping or visit google addresses
-
Good Afternoon,
I have a firewall in place with the latest version of PFsense.
It is set up to manager a captive portal and has a opt1 interface servicing several access points for WIFI.
A couple weeks ago after working fine it will randomly stop allowing users, both hard wired and wireless, from accessing google.I have found that you can not ping any of the google ip addresses either.
I have backed up the config and set the firewall to factory defaults and reapplied the config and I have also moved the backup to a second new firewall. So it does not seem to be hardware related.If you take the firewall down and hook directly to the modem it will work fine. I also found that if you disabled the opt1 interface and then reboot it will work for a bit and then go down again and then after a period of time it will come back up.
Is there anything i can do to set a log or something to find out what is causing this issue or does anyone have any troubleshooting tips?
Thanks!

Are you running any IDS, etc. i have SNORT running and noticed a few months ago that google ip addresses would somehow get on the block list, don't know whats google has changed? i ended up creating a Google white list and placed all google wildcard domains on it, you can google how to do it. there are heaps
