PfSense can not ping ipv6 GW
I am running pfSense in a KVM instance and a KVM guest connected to the pfSense instance. The guest can ping to the gateway and to outside ipv6 addresses (sometimes it loses the first 8 packages). However the pfSense instance can ping only now and then (1 of 30 times) the gateway and I can not find out, why.
The host system of the instances can ping to the ipv6 gateway without any problems.
Thanks for your help.
