25. Filter Commands

25.1. config filter dhcp_server
 Description
This command has two purposes: to specify to filter all DHCP server packets on the
specific port and to specify to allow some DHCP server packets with pre-defined
server IP addresses and client MAC addresses. With this function, we can restrict the
DHCP server to service specific DHCP clients. This is useful when two DHCP servers are
present on the network; one of them can provide the private IP address and the
other can provide the public IP address.
Enabling filter DHCP server port state will create one access profile and create one
access rule per port (UDP port = 67). Filter commands in this file will share the same
access profile. Addition of a permit DHCP entry will create one access profile and
create one access rule. Filter commands in this file will share the same access profile.
