ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308 Reference Manual 4. From the Service drop-down list, select HTTP for a Web server. 5. From the Action drop-down list, select ALLOW Always. 6. In the Send to LAN Server field, enter the local IP address of your Web server PC (192.168.1.2 in this example). 7. From the WAN Destination IP Address drop-down list, select the Web server. In this example, the secondary 192.168.55.10 (WAN1) address is shown. You first must have defined this address on the WAN1 Secondary Addresses screen (see "Configuring Secondary WAN Addresses" on page 2-25). 8. Click Apply to save your settings. The rule is now added to the Inbound Services table of the LAN WAN Rules screen. To test the connection from a PC on the Internet, type http://, where is the public IP address that you have mapped to your Web server. You should see the home page of your Web server. LAN WAN or DMZ WAN Inbound Rule: Specifying an Exposed Host Specifying an exposed host allows you to set up a computer or server that is available to anyone on the Internet for services that you have not yet defined. To expose one of the PCs on your LAN or DMZ as this host: 1. Create an inbound rule that allows all protocols. 2. Place the rule below all other inbound rules. See an example in Figure 4-14 on page 4-25. Warning: For security, NETGEAR strongly recommends that you avoid creating an exposed host. When a computer is designated as the exposed host, it loses much of the protection of the firewall and is exposed to many exploits from the Internet. If compromised, the computer can be used to attack your network. 4-24 v1.0, April 2010 Firewall Protection

LAN WAN or DMZ WAN Inbound Rule: Specifying an Exposed Host
Specifying an exposed host allows you to set up a computer or server that is available to anyone on
the Internet for services that you have not yet defined.
To expose one of the PCs on your LAN or DMZ as this host:
1.
Create an inbound rule that allows all protocols.
2.
Place the rule below all other inbound rules.
See an example in
Figure 4-14 on page 4-25
.
Warning:
For security, NETGEAR strongly recommends that you avoid creating an
exposed host. When a computer is designated as the exposed host, it loses
much of the protection of the firewall and is exposed to many exploits from
the Internet. If compromised, the computer can be used to attack your
network.
