RS700 pinging Google DND every 4-5 secs on AP Mode

I am currently using my RS700S in AP mode behind a pfSense firewall. I noticed the router is pinging 8.8.8.8 and 8.8.4.4 every 4-5 secs showing up in block alerts, more of nuisance than anything with it flooding the logs rather than any connectivity. I assume it's trying to check for an internet connection, but there needs to be a way to block/stop the RS700S when in AP mode. I assume this is not just the RS700 but other models probably doing the same as a lot of them share similar core firmware.
