Each interface has a primary IP address as well as one or more optional secondary IP addresses. An IP address of
IP addresses are specified using CIDR notation, which uses an address/subnet bits format. The subnet bits refer to the number of bits that are set in binary in the subnet mask from the left hand side. For example, a subnet mask of
Settings like the host name and time zone can also be changed on this page. If you are using the anti-spam features of Cipafilter, make sure that the host name and domain are correct. Ensure that the
Logging Database Connect String
Cipafilter can use a remote filter as a logging database server for the purposes of scaling performance. This value is a PostgreSQL connect string that instructs the filter to log to a remote database server; it should be configured by tech support.
Enterprise Database Connect String
This PostgreSQL connect string describes how the filter connects to the Cipafilter Enterprise monitoring product (if it has been purchased by your organization); it should also be configured by tech support.
Primary and Secondary DNS
Enter external DNS servers here. We recommend leaving these blank to use the Cipafilter's internal DNS server.
Clicking this check box will cause the Cipafilter to become a bridge, bridging all of its Ethernet interfaces together into one logical interface. In this configuration the Cipafilter acts like a switch. Installing the Cipafilter this way may require the restarting of any Cisco routers on the subnet to clear their ARP caches. Any IP addresses you wish to configure on Cipafilter for management can be applied to any interface if this box is checked.
Note: The filter should always be rebooted after disabling bridging to allow for the proper re-configuration of network interfaces.
Primary Internet Connection
The interface closest to the Internet should be chosen as your Primary Internet connection. This is used primarily if you enable NAT on any of your other subnets. If a subnet is being NATed, all packets coming from it through the router are translated to appear as if they are coming from the IP you designate with this setting.
NAT is used to allow a group of machines with private IP addresses like
