Port 111 vulnerable

Hi,

 

I keep getting messages from Virgin regarding portmapper vulnerability on my Hub 3, the latest is this one:

"Please take action now: your home devices could be at risk

We have been alerted on five separate occasions a device connected to your home network has been identified as having a potential Portmapper vulnerability." (clipped)

 

I followed the advice early on and removed any rules that would keep port 111 open. I've scanned the port and received the response 'Port 111 is closed on [my IP address]' on each occasion. Why do I keep receiving these messages?

Re: Port 111 vulnerable

FYI: see mDNS and SSDP vulnerabilities a suggestion for devices in the DMZ, specifically Using Port Forwarding to drop the inbound traffic and  Hub 3 example shown here; though forwarding different ports the process would be similar for port 111
