Hi,
I have a problem with two FreeBSD (12.1-RELEASE, 11.3-RELEASE) installations.
After a couple of hours they lose their IPv6 connection. If I then try to establish a connection or simply ping them, it takes a very long time until a connection is re-established.
My hosting provider claims it is FreeBSD's fault. Maybe one of you has an idea. For years the configurations worked without any problems.
I use PF as firewall, but disabling it doesn't help.
Additionally I tried to set the ndp manually, also without success.
