Network Access Rules evaluate 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.

The ability to define Network Access Rules is a very powerful tool. Using custom rules, 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.

RV082 has the following Default Rules.
* All traffic from the LAN to the WAN is allowed.
* All traffic from the WAN to the LAN is denied.
* All traffic from the LAN to the DMZ is allowed.
* All traffic from the DMZ to the LAN is denied.
* All traffic from the WAN to the DMZ is allowed.
* All traffic from the DMZ to the WAN is allowed.

Custom rules can be created to override the RV082 default rules,  but there are four additional default rules that will be always active, and custom rule can not override the four rules.
* 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.

Besides the Default Rules, all configured Network Access Rules are listed in the table, and you can choose the Priority for each custom rule. Click the Edit button to edit this rule, and click the Trash Can icon to delete the rule. 

Click Add New Rule button to add new Access Rules or click the Restore to Default Rules button to restore to the default rules, and all custom rules will be deleted.
