- Controlling resources and organizational units
  SafeLinx gives you control over all resources and organizational units.
- Customizing network configuration
  SafeLinx lets you customize your network configuration.
  - Setting up a broadcast group
    You can define a group of users to which to broadcast a message.
  - Sending broadcast messages
    You can send a text message to all active users on a SafeLinx Server through broadcast messages.
  - Adding a network connection
    A mobile network connection (MNC) is the interface to a network provider.
  - Configuring intelligent connections
    You can configure the SafeLinx Server and SafeLinx Clients on Linux, Windows, or Windows CE to determine which protocol with which to connect to an Internet Protocol (IP) transport.
  - Configuring TCP-Lite
    A TCP-Lite transport is applied to a transport profile, which is a set of configuration properties that are applied to a connection profile. They are then applied to an MNC to control the performance options between an MNC and the SafeLinx Clients that connect to it.
  - Configuring HTTP codec
    You can add an HTTP codec and configure its properties.
  - Looking up users in another directory service
    You can store user account data in the same directory server (DSS) as all other SafeLinx Server resources, or you can choose to look up or manage user account data in a separate enterprise directory service. If you choose to look up data in an enterprise directory service, you must first create a directory server resource for each enterprise directory service you want to use.
  - Setting up IP addressing
    When you define a mobile network interface (MNI) and choose for IP traffic to be routed statically rather than using a dynamic host configuration protocol (DHCP) server, you set up a subnetwork.
  - Setting up network address translation
    To set up the SafeLinx Server to act as an agent between a public network and a private network and perform network address translation, add a network address translator (NAT).
  - Filtering incoming and outgoing data
    You can create filters to be associated with a mobile network interface (MNI) to control data access to and from all IP-attached clients.
  - Redirecting packets to and from SafeLinx Server
    Packet mapping is a way to redirect data through a mobile network interface (MNI).
  - Routing traffic to a subnetwork
    A routing alias is a SafeLinx Client acting as a multihomed destination gateway to route data between the SafeLinx Server and a subnetwork that you specify.

Setting up IP addressing

When you define a mobile network interface (MNI) and choose for IP traffic to be routed statically rather than using a dynamic host configuration protocol (DHCP) server, you set up a subnetwork.

A subnetwork is an extension to the basic IP addressing scheme and consists of a contiguous range of IP addresses where a portion of the host address is interpreted as the local network address.

The mask is a 32-bit mask that is used to identify the subnetwork address bits in the host portion of an IP address. Every bit that is not 0 is an exact match.

To define a subnetwork, supply the host IP address for the network and the subnet mask that extends the network. For example, if a host IP address of 34.34.73.1 is extended by 255 IP addresses, the mask for that IP address is 255.255.255.0

To set up dynamic shared IP addressing, define a Dynamic Host Configuration Protocol (DHCP) group. Right-click the organizational unit (OU) in which you want the group added. From the menu, click Add Resource > Group > DHCP group.

When a user is defined to a DHCP group, an available IP address from the shared pool is assigned to that user at login time.

A DHCP group contains pools of IP addresses, which are specified as one or more ranges of addresses and single addresses and also specified as one or more ranges of addresses and single addresses that are to be excluded from the group.

The ranges can be:

From lowest IP address to highest IP address
An IP address and a mask
A number of addresses starting with a given IP address for a given number of addresses
