Connecting the VPN Firewall to the Internet

ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308

9. Click Test to evaluate your entries. The VPN firewall attempts to make a connection

according to the settings that you entered.

10. Click Apply to save any changes to the WAN ISP settings. (Or click Reset to discard any

changes and revert to the previous settings.)

If you want to manually configure an additional WAN interface, select another WAN interface

and repeat these steps. You can configure up to four WAN interfaces.

When you are finished, click the Logout link at the upper right corner of the web

management interface or proceed to additional setup and management tasks.

Configure the WAN Mode

The VPN firewall can be configured on a mutually exclusive basis for either auto-rollover (for

increased system reliability) or load balancing (for maximum bandwidth efficiency). If you do

not select load balancing, you need to specify one WAN interface as the primary interface.

• Load balancing mode. The VPN firewall distributes the outbound traffic equally among

the WAN interfaces that are functional. You can configure up to four WAN interfaces. The

VPN firewall supports weighted load balancing and round-robin load balancing (see

Configure Load Balancing and Optional Protocol Binding on page 36).

Note: Scenarios could arise when load balancing needs to be bypassed

for certain traffic or applications. If certain traffic needs to travel on a

specific WAN interface, configure protocol binding rules for that

WAN interface. The rule should match the desired traffic.

• Primary WAN mode. The selected WAN interface is made the primary interface. The

other three interfaces are disabled.

• Auto-rollover mode. The selected WAN interface is defined as the primary link, and

another interface needs to be defined as the rollover link. The remaining two interfaces

are disabled. As long as the primary link is up, all traffic is sent over the primary link.

When the primary link goes down, the rollover link is brought up to send the traffic. When

the primary link comes back up, traffic automatically rolls back to the original primary link.

If you want to use a redundant ISP link for backup purposes, select the WAN port that

should function as the primary link for this mode. Ensure that the backup WAN port has

also been configured and that you configure the WAN failure detection method on the

WAN Advanced Options screen to support auto-rollover (see Configure the Auto-Rollover

Mode and Failure Detection Method on page 34).

Whichever WAN mode you select, you need to also select either NAT or classical routing, as

explained in the following sections.
