Network Setup
=============
The SK-VPN supports multiple interfaces Roles: LAN, WAN, and MGMT.
The SK-VPN allows administrators to assign IP Adressess and Routes to interfaces.
The SK-VPN supports IPv4 addresses. IPv6 will be supported in the future.

.. _interface_setup:

Interface Address Setup
-----------------------

The Web UI Network page is used to manage Interface Addresses.

.. _interface_role_assignment:


Interface Role Assignment
-------------------------
The SK-VPN supports multiple interfaces Roles: LAN, WAN, and MGMT.
Upon initialization the SK-VPN attempts to assign interfaces a LAN or WAN role based on IP address assignments.

The SK-VPN allows users to re-assign the role of an interface to be either LAN or WAN.
A Reboot is required to take effect.

The Web UI Network -> Interfaces -> Assign Interface Roles is used to manage Interface Roles.

.. _fib_table:

FIB Table
---------
The SK-VPN determines how network packets are routed based on multiple decision points including:
the system routes, IPsec connections and filtering rules. 
The Forwarding Information Base (FIB) table is used to determine the routing path for a packet.

Direct manipulation of the FIB table is not allowed as it is a combination of routing and security settings. 
The FIB is useful to troubleshoot routing problems.

The Web UI Network -> FIB displays the current FIB Table.
