All Rules вЂ“ Lists all of the Access Rules on one page This can be confusing, so SonicWall created two additional views to better organize your firewall rules: Matrix view and Drop-down Box view. Note: The default view for the access rules lists all of the rules together on one page. The Access Rule will match the Address Object and then perform a Deny of that packet. Verify that the Address Object was created by viewing it at the bottom of the page.Д¬omplete these steps in the SonicWall GUI in order to create an Access Rule to block the Gmail website. For example: 172.16.20.0 / 255.255.255.0ДЇQDN вЂ“ Fully Qualified Domain Name of one or multiple IP addresses. Network вЂ“ Range of IP addresses that are defined by a network and a subnet mask. Range вЂ“ Range of IP addresses listing only the beginning and ending IP addresses. Host вЂ“ Single IP address of a single host on the network. вЂњType:вЂќ can be any of the following values:

Zone Assignment: WAN (Choose WAN because Gmail exists on the internet, which is part of the WAN zone) Name: Gmail Address Object (type this in) On the Address Object page, select the following: Scroll down to the Address Objects section on the bottom half of the page, and then click on Add. Note: The firewall does a DNS lookup on to find the IP addresses associated with that URL and then compares the TO address in the packet header to those addresses. The Gmail website actually has the URL of, so we need to create an address object for. There are two stages to this configuration process:Д¬omplete these steps in the SonicWall GUI in order to create an address object for the Gmail website.

Therefore, using Application Control and Application Firewall Rules is the preferred method of writing firewall rules in SonicWall Firewalls. Next Generation firewalls use Deep Packet Inspection (DPI) to look at the header AND the payload of the packet in order to more securely scan the packet. This is because Access Rules only look at the header of the packet and not the payload of the packet. This order will allow you to restrict what traffic will be going through the firewall.ДЇor Next Generation Firewalls, Access Rules are NOT the recommended method of writing application firewall rules. Place rules in this order: most permissive first and most restrictive last, with last rule denying everything. The firewall uses the first policy that that the packet matches. The packet header contains the following information: Access Rules only look at the network packet header in order to determine whether to Allow/Deny/Drop the network packet. SonicWall Access Rules are similar to Access Control Lists that are seen in other vendorsвЂ™ firewalls, but with added functionality.ДЄccess Rules are used to Allow/Deny/Drop network packets between the SonicWall Firewall Zones. In this section, you are presented with the information to configure the Firewall to block everyone from the Gmail website using the firewall access rules.ДЄccess Rules are what traditionally define a firewall. If your network is live, make sure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration.

Or you find out that the WAN IP ADDRESS is most definitely malicious as in the following IP from OFFSHORE RACKS: 181.174.167.251 Even though you have the DDOS attack proxied via FIREWALL-SETTINGS > FLOOD-PROTECTION as 'Proxy WAN client connection when attack is suspected', you still want to send a message that these types of activities will not be tolerated. Let's say you have an IP ADDRESS on the WAN trying to perform a DDOS or a SYN-FLOOD attack to your location.
