IPv6 Protocol Names and Numbers
The IPv6 protocol can be one of the following well-known names or any IPv6 protocol number from 0 through 255:
- Authentication Header (AH) protocol
- Encapsulating Security Payload (ESP)
- Internet Control Message Protocol (ICMP)
- Internet Protocol Version 6 (IPv6)
- Stream Control Transmission Protocol (SCTP)
- Transmission Control Protocol (TCP)
- User Datagram Protocol (UDP)
Note: TCP and UDP filters will be matched only if they are listed as the first option in
the extension header.
For TCP and UDP, you also can specify a comparison operator and port name or number. For example, you can configure a policy to block web access to a specific website by denying all TCP port 80 (HTTP) packets from a specified source IPv6 address to the website IPv6 address.
IPv6 ACLs also provide support for filtering packets based on DSCP.
