DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
Remember that allowing inbound services opens holes in your firewall. Only enable those ports
that are necessary for your network. Following are two application examples of inbound rules:
Inbound Rule Example: A Local Public Web Server
If you host a public Web server on your local network, you can define a rule to allow inbound Web
(HTTP) requests from any outside IP address to the IP address of your Web server at any time of
day. This rule is shown in
Figure 4-5
The parameters are:
• Service: From this list, select the application or service to be allowed or blocked. The list
already displays many common services, but you are not limited to these choices. Use the
Services menu, see
applications that do not already appear.
• Action: Choose how you want this type of traffic to be handled. You can block or allow
always, or you can choose to block or allow according to the schedule you have defined in the
Schedule menu.
• Send to LAN Server: Enter the IP address of the computer or server on your LAN which will
receive the inbound traffic covered by this rule.
• WAN Users: These settings determine which packets are covered by the rule, based on their
source (WAN) IP address. Select the desired option:
– Any: All IP addresses are covered by this rule.
– Address range: If this option is selected, you must enter the Start and Finish fields.
