You can configure a Juniper Networks router/firewall, such as a Dell J-SRX100H, which is manufacturered by Juniper Networks by connecting a network cable between one of the 0/1 through 0/7 ports on the SRX100; don't use the 0/0 port, because that is the default port for the "untrusted" side of the device, i.e., for connections on the "outside" or Internet-facing side of the device. If you have the connected device set to obtain an IP address by the Dynamic Host Configuration Protocol (DHCP), it will be assigned an address from the 192.168.1.1/24 subnet, 192.168.1.2. You can then log into the router by opening a browser window and pointing the browser to http://192.168.1.1.
