Network Settings
A Defense Center’s network settings allow it to communicate on your
management network. If you already configured the network settings, this
section of the page may be pre-populated.
The Sourcefire 3D System provides a dual stack implementation for both IPv4
and IPv6 management environments. You must specify the management
network protocol (
IPv4
,
IPv6
, or
Both
). Depending on your choice, the setup page
displays various fields where you must set the IPv4 or IPv6 management IP
address, netmask or prefix length, and default gateway:
•
For IPv4, you must set the address and netmask in dotted decimal form (for
example: a netmask of 255.255.0.0).
•
For IPv6 networks, you can select the
Assign the IPv6 address using router
autoconfiguration
check box to automatically assign IPv6 network settings.
Otherwise, you must set the address in colon-separated hexadecimal form
and the number of bits in the prefix (for example: a prefix length of 112).
You can also specify up to three DNS servers, as well as the host name and
domain for the device.
