Don't filter it at all at the ISP level for your customers. The neighbor discovery packets can't be abused from other links because they will be discarded when they don't have TTL of 255. Make sure you reject RAs from the customers on your PPP links. Although, inside a link (e.g. on a office network), filtering for certain packages like RA is needed to avoid certain intended or accidental stuff. Other stuff like the destination unreachable must not be blocked at all. ICMPv6 isn't a security risk itself. -- Gruß Marco Send unsolicited bulk mail to [email protected] ----- To unsubscribe from this mailing list or change your subscription options, please visit: https://mailman.ripe.net/mailman3/lists/ipv6-wg.ripe.net/ As we have migrated to Mailman 3, you will need to create an account with the email matching your subscription before you can change your settings.
