General Discussion / Re: DNS traffic from WAN IP to Google servers

Thanks! Of course I only saw the traffic in the log after NAT.

There is an exact match of traffic from someones specific client and the entries I saw before.

I got blinded by the source IP, and blamed the FW.

Thanks again :-)

Hi fabian,

Thanks for your reply.

The WAN-address, default GW and DNS-servers is static configured.

I have thought that a client might use Google DNS servers, but in the FW-logs the source IP of the traffic is the WAN-address of the FW. Furthermore the FW is pinging 8.8.8.8 (also from the WAN IP).

I have exported the config, and in the XML there is no mention of "8.8".

When searching in logs in my other OPNsense (16.x) FWs I can't see similar traffic, so this might be an error in the version I've got.

General Discussion / DNS traffic from WAN IP to Google servers

Hi,

I see quite a lot of DNS queries from the WAN-interface of a newly installed OPNsense 17.1.3-i386 to 8.8.8.8 and 8.8.4.4.

I think it must be the apinger which is using Google DNS, but I don't quite understand why this is necessary for monitoring my GW.

I don't wish to feed the Google. Can I avoid sending traffic in their direction?
