Firewall Tab - Access Rules
Network Access Rules evaluate the network traffic's Source IP address, Destination IP address, and IP protocol
type to decide if the IP traffic is allowed to pass through the firewall.
When defining Network Access Rules, remember that it is possible to disable all firewall protection or block all
access to the Internet. Use extreme caution when creating or deleting Network Access Rules. Custom rules can
be created to override Default Rules, but there are four default rules that will be always active, and custom rules
cannot override these four rules. These are:
* HTTP service from LAN side to RV082 is always allowed.
* DHCP service from LAN side is always allowed.
* DNS service from LAN side is always allowed.
* Ping service from LAN side to RV082 is always allowed.
The Network Access Rules are broken into a table, with these features:
Jump to: Select from this pull-down menu which page of Rules you wish to display.
Entries Per Page: From this pull-down menu, you can select how many entries will be displayed per page.
Priority: This shows, depending upon the number of Rules entered, the numeric order of Rules having higher or
lower priority.
Enable: Enable or disable Rules by clicking on the corresponding box.
Action: Allow or Deny traffic to or from specific network or Internet destinations.
Service: This shows the services on your network to which this Rule will apply?
Source Interface: This shows to which port this rule applies.
Source: Displays the source of the traffic affected by the Rule. For instance, if the source of the traffic is on your
network, this will display LAN. Any means that the traffic can originate from any source.
Destination: Displays the destination of the traffic affected by the Rule. For instance, if the destination of the
traffic is your network, this will display LAN. Any means that the traffic can go to any destination.
Time: This displays the hours (in military time) during which the Rules apply.
Day: This displays the day(s) on which the Rule applies.
