NAS in Security Isolation Mode but sending out tons of dns requests?

[jester]

Please explain how I can stop my nas from sending out 12 dns queries for ifconfig.me, ip4.seeip.org, myexternalip.com every 11 seconds, even though its in Security Isolation mode and not supposed to be communicating with anything outside the local ip block it's in? I guess I can understand it still sending out occasional requests to app.terra-master.com, update.terra-master.com. At least those are only every 3 minutes or so. Additionally, it's also trying to reach out to www.tnas.online, which again seems counter to the whole Security Isolation Mode.

Tnas.online is unchecked and I don't recall ever trying to set that up, so why it's trying to connect there is unknown. My only guess for the others is that it's trying to find the wan ip?

Please help. Thanks

Could you please let me know if there is a successful response each time you send to ifconfig.me, ip4.seeip.org, and myexternalip.com?
For the software of our current TNAS system such as www.tnas.online, there is no request limit when enabling the security isolation mode. Because the background application is enabled, if you don't want to request the software, you can disable it.
