DNS Leak: router logs have *.self-check.portmaster.home.arpa

*.self-check.portmaster.home.arpa is used for an internal self-check of Portmaster. If you see these queries anywhere, the system integration is not working and you should get a notification about that in Portmaster after a while and you should really check your setup.

These queries cannot really leak anywhere by design, as they are only valid in the LAN context and MUST be discarded anywhere else per RFC.

Where do you think is the problem ? WIndows ? Router ? Router DNS Client ? DNS Server?

This isn't necessarily the case, no? maybe I'm misunderstanding. If you have something that logs all DNS traffic on your network, this will naturally and should be expected to show up.

Could you elaborate?
