Connecting the VPN Firewall to the Internet
41
ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308
Configure Secondary WAN Addresses
You can set up a single WAN Ethernet port to be accessed through multiple IP addresses by
adding aliases to the port. An alias is a secondary WAN address. One advantage is, for
example, that you can assign different virtual IP addresses to a web server and an FTP
server, even though both servers use the same physical IP address. You can add several
secondary IP addresses to a single WAN port.
After you have configured secondary WAN addresses, these addresses are displayed on the
following firewall rule screens:
In the WAN Destination IP Address drop-down lists of the following inbound firewall rule
screens:
- Add LAN WAN Inbound Service screen
- Add DMZ WAN Inbound Service screen
In the NAT IP drop-down lists of the following outbound firewall rule screens:
- Add LAN WAN Outbound Service screen
- Add DMZ WAN Outbound Service screen
For more information about firewall rules, see Use Rules to Block or Allow Specific Kinds of
Traffic on page 82).
Note: It is important that you ensure that any secondary WAN addresses
are different from the primary WAN, LAN, and DMZ IP addresses
that are already configured on the VPN firewall. However, primary
and secondary WAN addresses can be in the same subnet. The
following is an example of correctly configured IP addresses:
Primary WAN1 IP address: 10.0.0.1 with subnet 255.0.0.0
Secondary WAN1 IP: 30.0.0.1 with subnet 255.0.0.0
Primary WAN2 IP address: 20.0.0.1 with subnet 255.0.0.0
Secondary WAN2 IP: 40.0.0.1 with subnet 255.0.0.0
DMZ IP address: 192.168.10.1 with subnet 255.255.255.0
Primary LAN IP address: 192.168.1.1 with subnet 255.255.255.0
Secondary LAN IP: 192.168.20.1 with subnet 255.255.255.0
To add a secondary WAN address to a WAN port:
1. Select Network Configuration > WAN Settings. The WAN screen displays (see
Figure 10 on page 25).
2. Click the Edit table button in the Action column of the WAN interface for which you want to
add a secondary address. The WAN ISP Settings screen displays (see Figure 11 on
page 26, which shows the WAN1 ISP Settings screen as an example).
