Influence of Pi-hole on UPnP Portmapping?

Influence of Pi-hole on UPnP Portmapping?

None.

Certainly not any incoming traffic.
As far as connections to public servers via domain names are concerned: I cannot answer that, as I do not know AnyDesk, and additionally, I cannot know what blocklists you have decided to use.

My answer in that post applies.

Pi-hole is a filtering DNS forwarder - it isn't concerned with ports, so it wouldn't interfere with any of your router's port mappings.

It may, however, interfere with AnyDesk if any of the domains that AnyDesk would ask resolution for would be on one of the blocklists you've configured for your Pi-hole, and blockage of that domain would prevent AnyDesk to operate as expected.

How do I determine what domain an ad is coming from? may help in finding out about relevant domains.


As detailed in Pi-hole's documentation, port 4711 is meant to be accessible via the loopback interface exclusively. It shouldn't be opened for outside access.
