Cannot Block IPv6 Traffic

  • 1.  Cannot Block IPv6 Traffic

    Posted Nov 07, 2017 12:39 PM

    Hi,
        In my IAP225, I am trying to block IPv6 traffic on a specific network. My goal is to allow only IPv4 traffic and block all ipv6 traffic going in the network. To achive this, I have created a network profile and associated a ACL rule to the profile. The acl rule to deny ipv6 traffic is given below.

        84:d4:7e:c6:d5:74 (Access Rule "TEST") # rule any any match ipv6 any any deny

    However, this is not working. I can still send ipv6 traffic(ping traffic) over the network.

    Set-up details: I have a set-up with 2 Aruba AP's and each WAP is connected with one Client(laptop's). The Laptop's are configured with IPv6 addresses(default link local address).With the above ACL rule configured in Aruba, I expect, all IPv6 traffic should be dropped however, that is not happening. I can still reach other client in the network via ping.

    Aruba WAP Type    : IAP225
    Firware Version    : 6.5.0.0-4.3.0.0_56428

    Please let me know is there any way to block only IPv6 traffic?

    Thanks in advance.

    Thanks Vijay for helping me in this issue. 

     

    The CLI indeed has an option to block to block IPv6 traffic while configuring the ACL rules. Use the below options based on the interface you are using.

    1. Use 'v6-deny" if you are using GUI

    2. Use "raw" option in CLI.

     

    A sample ACL rule is given below.

          rule any any match raw any any deny

     

    Thanks,

    Shiva
