Issues with Printing and Casting services after network segmentation.

[Brad6212]

I divided a flat network into two VLANs.  That really doesn't come into play here and I do understand routing just fine.

But...  even though printers and TVs are on the same subnet as our corporate PCs, discovery and Casting doesn't work as expected.

PCs are on a Radius Certificate based SSID

TVs and Printers are on another SSID, but the same vlan as the PCs

I can't understand why this doesn't work.  Printing can be done obviously with a driver referencing an IP address, but printer discovery doesn't work and previously discovered printers don't work.  PCs had some limited success casting to the TV, but MAC devices could not airplay to the TV.

Did anyone solve this or do I need to come up with another strategy?

You may need to configure Bonjour Forwarding, under the Firewall rules on the MX.

The settings here should suffice. You shouldn't need to configure on the SSID as well.

Thanks so much!  This worked perfectly.

This makes no sense. if its the same vlan and subnet, forwarding is not needed. Also, IMO, you are compromising your wireless security on that valn by add the printers and the TVs.  I would move the printers and tv into another separate vlan.

All of chromecast /casting and printing devices are in an isolated vlan from my secured wireless clients. Works great but you have to enable bonjour forwarding between the two segments and a reciprocal rule. like this on the MX. You can trim the services to whatever you require.
