IPv6 Connection problem with Firewall


Hi , I have connection issue with Security Groups.
I create a plan and add some IPs in to WhiteList.
The rule works well but after couple minutes, server cannot have a IPv6 connectivity.
So when I execute trace command on server, IPv6 getaway is not accessible.
I listen the interface and I found problem.
Server request v6 neighbor to ff00:0: but not requests are not responded or responses is don’t pass the vps.
When the default input policy is drop in input, NDP packets are not arrived to server.
So i fix this issue temporally with default input method set to allow and add another fire rule into policy list which is drop and same think in v6 after allowed ips .
