Connecting the VPN Firewall to the Internet
37
ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308
routes all outbound HTTPS traffic from the computers on the LAN through the WAN1 port. All
outbound FTP traffic is routed through the WAN2 port.
Protocol binding addresses two issues:
• Segregation of traffic between links that are not of the same speed.
High-volume traffic can be routed through the WAN port connected to a high-speed link,
and low-volume traffic can be routed through the WAN port connected to the low-speed
link.
• Continuity of source IP address for secure connections.
Some services, particularly HTTPS, cease to respond when a client’s source IP address
changes shortly after a session has been established.
Configure Load Balancing
 To configure load balancing:
1. Select Network Configuration > WAN Settings > WAN Mode. The WAN Mode screen
displays:
Figure 19.
2. In the Load Balancing Settings section of the screen, configure the following settings:
a. Select the Load Balancing Mode radio button.
b. From the corresponding drop-down list on the right, select one of the following load
balancing methods:
• Weighted LB. With weighted load balancing, balance weights are calculated
based on WAN link speed and available WAN bandwidth. This is the default
setting and most efficient load-balancing algorithm.
• Round-robin. With round-robin load balancing, new traffic connections are sent
over a WAN link in a serial method irrespective of bandwidth or link speed. For
example, if the WAN1, WAN2, and WAN3 interfaces are active in round-robin load
balancing mode, an HTTP request could first be sent over the WAN1 interface,
