Firmware:Status Connectivity Check Issue

[mooh]

Running "System:Firmware" Connectivity Check IPv6 ping doesn't seem to work, yet IPv6 connectivity itself looks fine:

Using "Interfaces:Diagnostics:Ping" or running ping from the command line the ping works just fine, same source, same destination address. Any ideas what might be wrong? This is 26.4.2.

Some sites do not respond to ping and some not to pings with older versions than 26.7.1. Other than that, take a look here:

Summary: the connectivity audit is not intended as a general diagnostic tool that your firewall passes "green" or fails "red". Only if you already encounter problems downloading and installing updates, you might be asked to run it by whoever is supporting you in that particular case.

Thanks for pointing this out. I didn't read the output of the connectivity check closely and didn't replicate the packet size in my own test. If I do, the ping fails everywhere.
