Logically, your setup should look like this in the end. inspected and passed by Transparent Mode providing Multicast has been activated on the Firewall > Multicast page, and multicast support has been enabled on the relevant interfaces. For example, a subnet can be created to isolate a section of a company network, such as finance, from network traffic on the rest of the LAN, WAN, or DMZ. So when the Workstation at the left attempts to resolve 192.168.0.1, the ARP request it sends is responded to by the SonicWALL with its own X0 MAC address (00:06:B1:10:10:10). For example, access rules can be created that allow access from the LAN zone to the WAN Primary IP address, or block certain types of traffic such as IRC from the LAN to the WAN, or allow certain types of traffic, such as Lotus Notes database synchronization, from specific hosts on the Internet to specific hosts on the LAN, or restrict use of certain protocols such as Telnet to authorized users on the LAN.Custom access rules evaluate network traffic source IP addresses, destination IP addresses, IP protocol types, and compare the information to access rules created on the SonicWall security appliance. was instead assigned to a Public (DMZ) zone: All the Workstations would be able to reach the Servers, but the Servers would not be able to initiate communications to the Workstations. The maximum number of Bridge-Pairs I have a few VLAN's in my Sonicwall but I can still ping devices from one VLAN to another. Interface Also make sure that the interface is configured for HTTP and SNMP so it can be managed from the DMZ by PCM+/NIM. Copyright 2023 SonicWall.

Virtual interfaces allow you to have more than one interface on one physical connection. IGMP is local to a subnet and can't (read: should never be) translated between subnets. This field is for validation purposes and should be left unchanged. Virtual interfaces- Virtual interfaces are assigned as subinterfaces to a physical interface and allow the physical interface to carry traffic assigned to multiple interfaces. I'm working on a similar problem and I noticed that even on a "private" network Windows will block a ping from a different subnet. . Management My problem is I have done all this and my router is still either not passing on the multicast information from Chromecast, or my PC's Join request is being ignored (or it's the other way, still fuzzy on how Chromecast works.

These VLAN subinterfaces can also be given Transparent Mode Address Object assignments, but in any event VLAN subinterfaces will be terminated rather than passed. Joshua Strickland - Hotel Technology Coordinator - OTO Development On the X1 Settings page, assign it a unique IP address for the internal Whereas other methods of transparent operation rely on ARP and route manipulation to achieve transparency, which frequently proves problematic, L2 Bridge Mode dynamically learns the topology of the network to determine optimal traffic paths. For my problem, it ended up that a managed switch after the sonicwall (installed by another company)had a typo in the gateway, preventing all subnets off of that switch to communicate with the primary LAN. CFS) are fully supported. Bulk update symbol size units from mm to map units in rule-based symbology. Transparent Mode- A method of configuring a Dell SonicWALL Security Appliance that allows the firewall to be inserted into an existing network without the need for IP reconfiguration by spanning a single IP subnet across two or more interfaces through the use of automatically applied ARP and routing logic. For example, you have a router on your network with the IP address of 192.168.168.254, and there is another subnet on your network with an IP address range of 10.0.5.0 - 10.0.5.254 with a subnet mask of 255.255.255.0. icon next to the default rule that implicitly blocks uninitiated traffic from the WAN to the LAN. and a Secondary Bridge Interface. This structure is based on secure objects, which are utilized by rules and policies within SonicOS Enhanced. Whether or not the Primary WAN is employed as part of a Bridge-Pair will not affect its ability to provide these stack communications (for example on a PRO 4100, X0+X2 and X3+X4 could be used to create two Bridge-Pairs separate of X1). The default Access Rules should be considered, although Is there a proper earth ground point in this switch box? Make sure you define the subnet mask of both networks properly (255.255.255.0) and create a Zone for both LANs. You might want to start from a wide-open firewall configuration to confirm that the firewall is actually sending IGMP group queries in each routed subnet and then set up a known-working multicast source/receiver to prove it's the firewall and not the Chromecast. Alternatively, the parent interface may remain in an unassigned state. Then we can use the firewall rules to set the rules. Supported on SonicWALL NSA series appliances, IPS Sniffer Mode is a variation of Layer 2 LAN+LAN, LAN+DMZ, WAN+CustomLAN, etc.) Static Routes. It is possible to manually add support for additional subnets through the use of ARP entries and routes. Ah ok, i think i just have a misunderstanding of how multicast is passed on. If you also need to pass VLAN tagged traffic, supported on SonicWALL NSA series appliances, Install the SonicWALL UTM appliance between the network and SSL VPN appliance, Regardless of your deployment method (single- or dual-homed), the SonicWALL UTM. Then access rules will be created to allow access between the default LAN zone and Printer zone but deny access from the LAN zone to the Server zone. What are you trying to ping? The WAN interface of the SonicWALL is used to connect to the SonicWALL Data Center for
