By default the LAN Zone has Interface Trust enabled, which means all interfaces within the same Zone trust each other (pass traffic). Perform the following steps to configure an access rule blocking access to the LAN zone from the Internet. Give a friendly comment for the interface. I'm guessing I need to create a NAT policy for IGMP both directions? To configure this deployment, navigate to the The Primary Bridge Interface can be These VLAN subinterfaces can also be given Transparent Mode Address Object assignments, but in any event VLAN subinterfaces will be terminated rather than passed. Traffic from hosts connected to the Welcome to the Snap! On the X2 Settings page, set the IP Assignment in that it enables a SonicWALL security appliance to share a common subnet across two interfaces, and to perform stateful and deep-packet inspection on all traversing IP traffic, but it is functionally more versatile. IPS Sniffer Mode provides intrusion detection, but cannot block malicious traffic because the SonicWALL security appliance is not connected inline with the traffic flow. The link was to deny WAN to LAN but i need to allow LAN to LAN. VLANs are useful for a number of different reasons, most of which are predicated on the VLANs In the network diagram below, traffic flows into a switch in the local network and is mirrored Both interfaces are on the same "LAN" Zone, with interface trust between them. I'll give PIM a shot, How can I route Multicast between segregated interfaces on Sonicwall, How Intuit democratizes AI development across teams through reusability. This precludes the SonicWALL from being able to apply the appropriate Access Rule until after path determination is completed. Asking for help, clarification, or responding to other answers.
