Installing the Firebox SSL VPN Gateway for the First Time
To configure TCP/IP Settings Using Network Cables
The Firebox SSL VPN Gateway has two network adapters installed. One network adapter communicates
with the Internet and client computers that are not inside the corporate network. The other network
adapter communicates with the internal network.
WatchGuard recommends that both network adapters be configured for maximum security. If only one
network adapter is used, it has to be routable for internal resources using Network Address Translation
(NAT). Also, if only one network adapter is used, throughput of network traffic is cut in half and can
cause a bottleneck of network traffic.
You can install the Firebox SSL VPN Gateway and configure TCP/IP settings using network cables, such
as two RJ-45 network cables, or cross-over cables. The RJ-45 cables are connected to a network switch
and to the Firebox SSL VPN Gateway. The cross-over cables are connected to a Windows computer and
the Firebox SSL VPN Gateway.
To configure TCP/IP settings using network cables
1Power on the Firebox SSL VPN Gateway.
After about three minutes, the Firebox SSL VPN Gateway is ready for its initial configuration with your network.
2 Open a Web browser and type https://10.20.30.40:9001 to open the Administration Portal. Use the
default user name and password of root and rootadmin.
3On the Downloads tab, under Firebox SSL VPN Gateway Administration Tool, click Install the
Firebox SSL VPN Gateway Administration Tool.
Follow the prompts to complete installation.
4 Log on to the Administration Tool using the default user name and password.
5On the Firebox SSL VPN Gateway Cluster tab, open the window for the Firebox SSL VPN Gateway.
6On the General Networking tab, under Interface 0 and Interface 1, next to IP Address, type the
new IP addresses of the appliance.
7In Subnet mask, enter the subnet mask that is appropriate for the IP address entered for the
interface(s).
8In External FQDN, type the fully qualified domain name.
Note
Important: The FQDN must match what is on the digital certificate and the license for the Firebox SSL
VPN Gateway.
9In Duplex Mode select the direction of the transmission data. The default setting is auto. You can
also select full duplex or half duplex.
10 In Speed Mode select the network speed of the adapter.
The default setting is auto. You can also select 10Mbps, 100Mbps, or 1000Mbps.
11 In Maximum Transmission Unit (MTU), select the maximum transmission unit that defines the
maximum size of the transmitted packet.
The default setting is 1500.
12 In Port, select the incoming port that is used for connections. The default is 443.
13 To configure a default gateway, in IP address, type the IP address of the gateway. In Interface,
select the network adapter on the Firebox SSL VPN Gateway with which the Default Gateway
communicates.
The IP address is the default gateway device, such as the main router, firewall, or server load
balancers, depending on your network configuration. This should be the same as the Default
Gateway setting that is on computers on the same subnet.
