That complain was in another thread. This is about the non working firewall in the router, which leaves my entire LAN accessible to Internet at large.
IPv6 has a security advantage in that with such a huge address space, it's extremely difficult for an attacker to find anything to attack. For example, you have a /64 prefix, which is 18.2 billion, billion addresses. This is the entire IPv4 address space squared. Out of that you will have at most a few dozen addresses. An attacker can scan all day, every day and not find anything. In contrast, with IPv4, it's not hard to find a target.
