### Configuring RealPort

This topic describes how to configure Digi One RealPort and PortServer TS devices to provide LAN-based servers with RealPort ports.

#### Starting Point

This procedure assumes that you have signed on as root and have or will

- Install RealPort software on each LAN-based host that will use RealPort ports and then properly configured RealPort software. See the appropriate RealPort documentation for more information.
- Properly cabled ports and devices
- Set up the devices connected to Digi ports
- Logged on to the Digi device as the administrator.

#### Notes

If you want to reserve certain ports for a specific RealPort host, supply a set auth command that specifies the following:

- The IP address of the host (on the ip field)
- The range of ports to be reserved (on the realport field)

#### Command Line

##### Procedure

1. Configure the RealPort TCP port by specifying set config realport=771. (note: 771 is the default TCP port. You can use another if this port conflicts with one in use already.)
2. Configure ports by supplying a set ports command that specifies the following:
   - The range of ports to configure for RealPort (on the range field)
   - dev=rp

##### Example

In this example, all of Digi device's ports are configured for RealPort. Ports 1 through 8 are reserved for one RealPort host and ports 9 through 16 are reserved for another.

`set config realport=771
set ports range=1-16 dev=rp
set auth ip=199.250.225.10 realport=1-8
set auth ip=199.250.225.11 realport=9-16`

#### Web Interface

This feature can be configured with the web interface on PortServer TS 8/16 systems. Digi One RealPort and PortServer TS 2/4 devices do not support the web interface.
