If you apply an ACL (Access Control List) policy using ACL that specifies L4 conditions, both IPv4 and IPv6 traffic will be matched. For example, the following ACL will match both IPv4 and IPv6 TCP packets that have their L4 destination port in the range of 120–150:
if { protocol tcp; destination-port 120 - 150; } Then { permit; count destIp; } }
