Potential Open DNS Resolver (ODNSR) vulnerability.
I'm getting an email telling me that I should check Port 53 as it is a potential issue.
However, Port 53 UDP is required in and out for Ring doorbells. To enable Live View on the iPhone whilst at home, I have to put the iPhone in the DMZ setting. This lets me see the Live View from the Ring doorbell at home, but it apparently keeps flagging up as an issue.
1 - is this really an issue as it's only the iPhone whilst in the house
2 - is there any other way I can resolve this without keep getting hassled by mail and email that I have a problem?
