4. In the Sequence Number field, specify a number in the range from 1 to 2147483647 to

5. Select or
specify values for one or more of the following match criteria:
• Seq
uence Number. Specify a number in the range of 1 to 2147483647 to identify the
IP ACL rule. You can create up to 50 rules for each ACL.
• Action. Sele

- Permit. Forward p

Specify the source IP address wildcard mask. Wild card masks
determine which bits are used and which bits are ignored. A wild card mask of
255.255.255.255 indicates that no bit is important. A wildcard of 0.0.0.0 indicates that
all of the bits are important. Wildcard masking for ACLs operates differently from a
