Online Security
Hi No matter what I do I can't seem to turn on virus protection via My Virgin Media. I keep getting the message 'Sorry the changes you made were not saved, please try again'. Also I have a new privacy warning "This network is blocking encrypted DNS traffic". Once again there is no option to turn this off anywhere. I noticed that there is another (paid) feature Advanced Security. Is it now the case that to access any security features, you have to pay?

Open DNS Resolver
Long story short(ish) - I recently changed my old router after a situation where my original started to fail DHCP requests. I also ended up with a new hub, but, the installer was also seeing that problem that he couldn't immediately fix. Since that router change I also started to receive Open DNS resolver messages and letters from VM. The config was a mirror of what I previously used with minimal WAN side services being used. Tests showed that port 53 wasn't open, yet, my router was indeed continuing to respond to and serving incoming DNS requests (checked from multiple IP addresses using nslookup). I did many tests including removing all devices on my local network, yet, the external DNS responses were still given. I raised the issue with the vendor and had no success so far and have asked for escalation today. Yesterday I SSH'd into the router and analysed what ports on which IP addresses were being monitored, and indeed, both my primary WAN and backup WAN connections were listed. This is from inside the router, not an external view. I have found a config on the router where the DNS provides only Server Fail messages, but this still leaves other vulnerabilities and probably ongoing messages and letters from VM. I suspect that it revolves around defining which DNS my internal devices use (having had numerous problems previously with VM DNS). I won't name the vendor and router yet, but, I think I may need to do that soon to get some attention from them. However, I see a number of other posts about the same manufacturer. I know their emails and letters will be automatically generated, but, there is little point in keeping on telling me while I try to mitigate and fix the problem. Is there any way of advising VM that I am aware of the problem and am dealing with it?
