Gentlemen:
I’ve searched the forum and maybe am not finding the answer because I don’t know the key words to search for. I’m using the hotspot feature of my cloud router switch that’s connected to a RB Metal. The RB Metal is set to bridge. I have two bridges: Passthrough and WiFi Bridge on the CRS. Port 24 is physically hooked up to the RB Metal. I have that port set to WiFi Bridge. All other 23 ports are set to the Passthrough Bridge. All systems function. My problem is Chromecast. The Chromecast is hard-wired to the CRS and on the Passthrough Bridge. In order to control the Chromecast, one has to use WiFi which is on the WiFi Bridge.
The DHCP server for the Passthrough Bridge is: 10.10.0.0/24
The DHCP Server for the Hotspot is the default of: 10.5.50.0/24.
This setup works, but the networks can’t “see” each other to allow remote control of the Chromecast. During a scan, if on the hotspot, you can’t see anything on the 10.10.0.0/24 network. I think this is a masquerade configuration. I need to set the firewall to allow the two subnets to communicate and allow my Chromecast that’s on the hard-wired “Passthrough” bridge to be seen by the WiFi “Hotspot” bridge.
