It creates a comprehensive Address Object for the entire zone and a inclusively permissive Access Rule from zone address to zone addresses. Asking for help, clarification, or responding to other answers. and Secondary Bridge Interfaces can be given Transparent Mode Address Object assignments, but the VLANs will be terminated by the SonicWALL rather than passed. Make sure you define the subnet mask of both networks properly (255.255.255.0) and create a Zone for both LANs. Granular controls Block content using the predefined categories or any combination of categories. Navigate to the Policy | Rules and Policies | Access rules page. Traffic will be intelligently routed in/out of On X4 Subnet, I can get to the Sonicwall admin page via both X0 and X4 interface address, but X4 cannot ping any other X0 addresses, and no X0 devices can reach X4 addresses. If there were public servers, for example, a mail and Web server, on the Also make sure that the interface is configured for HTTP and SNMP so it can be managed from the DMZ by PCM+/NIM. Once static routes are configured, network traffic can be directed to these subnets. The SonicWall has 5 interfaces. packets with a log event such as TCP packet In other words, only those VLANs which are defined as subinterfaces will be handled by the SonicWALL, the rest will be discarded as uninteresting. page includes interface objects that are directly linked to physical interfaces. The default handling of VLANs is to allow and preserve all 802.1Q VLAN tags as they pass through an L2 Bridge, while still applying all firewall rules, and stateful and deep-packet inspection to the encapsulated traffic. I need to enable traffic between two different subnets connected to a SonicWall. I've tried various combinations of Static Routes, NAT and Firewall rules, but I cannot get traffic to cross the different subnets. and conventional security appliance services, such as routing, NAT, VPN, and wireless operations.

Use any of the additional interfaces you have. in at all), and connect X1 to the internal network. To learn more, see our tips on writing great answers. You need to hear this. If more than two interfaces, PortShield interface may not operate within an L2 Bridge Pair. This precludes the SonicWALL from being able to apply the appropriate Access Rule until after path determination is completed. Custom routes and NAT policies can be added as needed. If there is no interface, traffic cannot access the zone or exit the zone. Please take a reference at the below KB article for access rule creation. Once the routers ARP cache is cleared, it can then send a new ARP request for 192.168.0.100, to which the SonicWALL will respond with its X1 MAC 00:06:B1:10:10:11.
