Ping and packet loss when ipv6 allow box is checked.
-
Recently I noticed some network issue with my pfsense box.
When I ping any external IP address or even the box itself, there's some high latency ping coming out of nowhere.
64 bytes from 8.8.8.8: icmp_seq=0 ttl=43 time=23.160 ms
64 bytes from 8.8.8.8: icmp_seq=1 ttl=43 time=23.480 ms

64 bytes from 8.8.8.8: icmp_seq=9 ttl=43 time=23.609 msWhen I uncheck the allow ipv6 box, the issue disappears instantly.
My IPv6 is configured in DHCP6 and I receive a proper ipv6 address from my ISP as well. Ipv6 gateway monitoring is responding correctly.

Thanks

One ping that is a little higher than the others should not interest you. No problem.
