This method also allows the parent physical interface on the SonicWALL to which a trunk link is connected to operate as a conventional interface, providing support for any native (untagged) VLAN traffic that might also exist on the same link. 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. The default behavior is to allow all subnets, but Access Rules can be applied to control traffic as needed. L2 Bridge Mode employs a learning bridge design where it will dynamically determine which Does Counterspell prevent from any further spells being cast on a given turn? Have you put a rule in your firewall to allow communications between those subnets? Also what I have had to do on the sonicwall in the past is add an address group 192.168.102./24 to the local subnets groups so it has the same access as the local subnet (10.189.101.x) flag Report . from LAN to DMZ but not DMZ to LAN). There is no need to declare interface affinities. If you think the Switch is the issue, how should I then best resolve it? If you do not have SonicWALL UTM security services subscriptions, you may sign up for free trials from the Security Service > Summary The SonicWall has 5 interfaces.
