Hello.

The device's firewall rules doesn't seem to have good support of ICMPv6. E.g. when I do "Firewall->Attack Defense -> Block Ping from WAN", the devide still lets the pings go through (it works fine for ICMPv4, btw).

Also, I tried to block the ICMPv6 using firewall rules (configureing a rule for ICMP/IPv6), those didn't have any effect either. So the only way to block ICMPv6 is to  block all the traffic for all the protocols and only create allow-rules for the traffic you need.. doesn't seem like a very well-thought-out approach.

Thanks,
