Running the Setup utility remotely

You can run the Setup utility remotely only from a workstation that is on the

same LAN as the unit. To allow remote connections for the Setup utility, the

BIG-IP comes with two pre-defined IP addresses, and a pre-defined root

password. The default root password is default, and the preferred default IP

address is 192.168.1.245. If this IP address is unsuitable for your network,

the BIG-IP uses an alternate IP address, 192.168.245.245. However, if you

define an IP alias on an administrative workstation in the same IP network

as the BIG-IP, the unit detects the network of the alias and uses the

corresponding default IP address.

Once the utility finishes and the system reboots, these default IP addresses

are replaced by the information that you entered in the Setup utility.

Setting up an IP alias for the default IP address before you start the unit

You must set up an IP alias for your remote workstation before you turn on

the unit and start the Setup utility. The remote workstation must be on the

same IP network as the unit. If you add this alias prior to booting up the

BIG-IP, the unit detects the alias and uses the corresponding address.

To set up an IP alias for the alternate IP address

The IP alias must be in the same network as the default IP address you want

the BIG-IP to use. For example, on a UNIX workstation, you might create

one of the following aliases:

◆ If you want the unit to use the default IP address 192.168.1.245, then add

an IP alias to the machine you want to use to connect to the unit using the

following command:

ifconfig exp0 add 192.168.1.1

◆ If you want to use the default IP address 192.168.245.245, then add an IP

alias such as:

ifconfig exp0 add 192.168.245.1

On Microsoft Windows

or Windows NT

machines, you must use a static

IP address, not DHCP. Within the network configuration, add an IP alias in

the same network as the IP in use on the unit. For information about adding

a static IP address to a Microsoft Windows operating system, please refer to

your vendor’s documentation.

Determining which default IP address is in use

After you configure an IP alias on the administrative workstation in the

same IP network as the BIG-IP and you turn the system on, the BIG-IP

sends ARPs on the internal VLAN to see if the preferred 192.168.1.245 IP

address is in use. If the address is appropriate for your network and is

currently available, the BIG-IP assigns it to the internal VLAN. You can

immediately use it to connect to the unit and start the Setup utility.
