I have a pepwave SOHO, firmware 8.1.0.
I can see from a downstream firewall that the pepwave device is constantly (multiple times per minute) attempting to connect to google dns at 126.96.36.199. These get blocked by the firewall.
I have pepwave configured to provide my internal DNS server to clients over DHCP (in LAN->DHCP Server->DNS Servers) and can confirm that any devices which connect to pepwave over wifi are given the expected (internal) DNS server IP by pep’s DHCP server. Name resolution works fine, so that’s all good.
I have also configured my same internal DNS server in Network Settings->DNS Resolvers.
I can test that pepwave can also resolve names correctly by using the ping test in the UI to external hosts.
So all DNS functionality is working fine and there isn’t any reference to 188.8.131.52 anywhere in the configuration that I can find.
And yet, pepwave keeps trying to connect to 184.108.40.206 constantly. How can I put a stop to these?
