Hi, I have a cloud server with Netcup running FreeBSD 13. I am having odd issues where IPv6 connectivity is intermittent. For example if I do a simple ping6, there is a delay/hang for 10s or more and then the replies come in. If I ping6 the second time I get replies instantly.
If I idle for 5 minutes and do a ping6 again, it hangs/delays again. I've spoken to the cloud team and they don't have IPv6 connectivity problems from their side to my server.
So I'm wondering if it has anything to do with the OS. Here's my /etc/rc.conf:
Is there anything else I can troubleshoot ? Thanks.

Code:
ipv6_activate_all_interfaces="YES"
ipv6_defaultrouter="fe80::1%vtnet0"
ipv6_ifconfig_vtnet0="2a03:xxxx:xx:axx::1/64"
ifconfig_vtnet0_alias0="inet6 2a03:xxxx:xx:axx::2/128"
ifconfig_vtnet0_alias1="inet6 2a03:xxxx:xx:axx::3/128"
ip6addrctl_policy="prefer_ipv4" # <- Temporary so that downloading ports/packages continue to work without delay.
Is there anything else I can troubleshoot ? Thanks.
