Firewall Support for IPv6
For a given client, a single ACLis used to firewall both IPv4 and IPv6 rules. A rule any any match any any
any permit in the access rule configuration will expand to two different ACL entries:
l any any any P6
l any any any P4
Similarly, if any IPv6 specific rule is added. For example, if any DHCPv6 or FTPv6 rule is added, the ACE would
be expanded as follows:
any 2002::/64 17 0-65535 546-547 6—destined to network 2002::/64 DHCPv6 is denied.
any 2001::10/128 6 0-65535 20-21 6—destined to host 2001::10 FTP is denied.
For all ACLs the W-IAP will have an implicit IPv4 and IPv6 allow all acl rule.
