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. See Figure 6-37.
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.The Router 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 above Default Rules, but there are four additional default rules that
will be always active, and custom rules cannot override these four rules. Besides the Default Rules, all configured
Network Access Rules are listed in the table, and you can choose the Priority for each custom rule.
* 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.
