Configuring IP/MAC Address Binding
IP/MAC Binding allows you to bind IP addresses to MAC address. Some machines
are configured with static addresses. To prevent users from changing static IP
addresses, IP/MAC Binding should be enabled. If the Cisco RV180/RV180W sees
packets with matching IP address but inconsistent MAC addresses, it drops those
packets.
To configure IP/MAC Address binding:
STEP 1
Choose Firewall > Advanced Settings > IP/MAC Binding. The table lists all the
currently defined IP/MAC binding rules and allows several operations on the rules.
STEP 2
Click Add to add a new rule.
STEP 3
In the name field, enter the name for this rule.
STEP 4
In the MAC Addresses field, enter the MAC Addresses (the physical address of
the piece of hardware) for this rule.
STEP 5
In the IP Addresses field, enter the IP Addresses to assign to the piece of
hardware.
STEP 6
Click Save.
Creating Custom Services
When you create a firewall rule, you can specify a service that is controlled by the
rule. Common types of services are available for selection, and you can create
your own custom services. This page allows creation of custom services against
which firewall rules can be defined. Once defined, the new service will appear in
the List of Available Custom Services table.
Adding a Custom Service
To create a custom service:
STEP 1
Choose Firewall > Advanced Settings > Custom Services.
STEP 2
Click Add.
STEP 3
Enter a service name for identification and management purposes.
