Hello, my acciu tunnel works as expected but i am not able to do serious firewalling with a DrayTek Vigor 2920n on my routed ipv6 subnet. Im only able to block all ipv6 connections to my routed subnet. But if try to allow for example ssh on one single ipv6 ip the whole routed subnet is accessible again on all ips and ports. Any hints on this? Googling around didnt worked out. Cheers Torsten
