I checked for updates of NDPMon, an IPv6 neighbour discovery protocol monitor and noticed I was way behind the current times. I also found out it can now monitor multiple network interfaces in once instance of the program, so I can keep an eye on both wired and wireless networks at home. Do take the advice of using the 'learning' mode of NDPMon as mentioned in the documentation for NDPMon. It makes getting the entire correct router advertisment correct into the datafile correctly so much easier. Downside is you have to run at a quiet time and after each IPv6 network reconfiguration. It would also be nice if NDPMon would report on which interface certain traffic was seen. Update: Ok, NDPMon still manages to warn about a router configuration it has learned itself. I found a remark in the NDPMon documentation/configuration page:Under the tag addresses are listed the IPv6 global addresses of the router. This is not required for the tool to work properly, but can be useful is the router send NA messages for its global addresses (to avoid raising NA router flag alerts).So I added the global IPv6 addresses of the routers, let's see if this decreases the noise.
