Nas-filter-Rule =
: Standard attribute for filtering inbound IPv4 traffic from an authenticated
client. Refer also to table 6-4, “Nas-Filter-Rule Attribute Options” on page 6-18.
HP-Nas-filter-Rule = : Legacy HP VSA for filtering inbound IPv4 traffic from an authenticated
client. Refer also to table 6-4, “Nas-Filter-Rule Attribute Options” on page 6-18.
“ . . . “ : Must be used to enclose and identifies a complete permit or deny ACE syntax
statement. For example: Nas-filter-Rule=”deny in tcp from any to 0.0.0.0/0 23”
< permit | deny >: Specifies whether to forward or drop the identified IP traffic type from the
authenticated client. (For information on explicitly permitting or denying all inbound IP
traffic from an authenticated client, or for implicitly denying all such IP traffic not already
permitted or denied, refer to “Configuration Notes” on page 6-24.)
in: Required keyword specifying that the ACL applies only to the traffic inbound from the
authenticated client.
< ip | ip-protocol-value >: Options for specifying the type of traffic to filter.
ip: Applies the ACE to all IP traffic from the authenticated client.
ip-protocol-value: This option applies the ACE to the type of IP traffic specified by either
a protocol number or by
tcp, udp, icmp, or (for IPv4-only) igmp. The range of protocol
numbers is 0-255. (Protocol numbers are defined in RFC 2780. For a complete listing,
refer to “Protocol Registries” on the Web site of the Internet Assigned Numbers
Authority at www.iana.com.) Some examples of protocol numbers include:
1 = ICMP 17 = UDP
2 = IGMP (IPv4 only)
6 = TCP*IPv4 traffic only.
from any: Required keywords specifying the (authenticated) client source. (Note that a
RADIUS-assigned ACL assigned to a port filters only the inbound traffic having a source
MAC address that matches the MAC address of the client whose authentication invoked the
ACL assignment.)
to: Required destination keyword.
any:
• Specifies any IPv4 destination address if one of the following is true:
– the ACE uses the standard attribute (Nas-filter-Rule). For example:
Nas-filter-Rule=”permit in tcp from any to any 23”
Nas-filter-Rule+=”permit in ip from any to 10.10.10.1/24”
Nas-filter-Rule+=”deny in ip from any to any”
– the HP-Nas-Filter-Rule VSA is used instead of the above option. For example, all
of the following destinations are for IPv4 traffic:
HP-Nas-filter-Rule=”permit in tcp from any to any 23”
HP-Nas-filter-Rule+=”permit in ip from any to 10.10.10.1/24”
HP-Nas-filter-Rule+=”deny in ip from any to any”
