Problems with mDNS across VLANs
I'm using gateway ER8411 v1.0 (firmware 1.3.1) on software controller v5.15.20.20.
I have three separated VLANs:
- VLAN1: home devices (192.168.1.0/24)
- VLAN2: shared devices (e.g. printers) (192.168.2.0/24)
- VLAN3: work devices (192.168.3.0/24)
I would like the printers on VLAN2 to be discoverable on the other two VLANs and have setup mDNS accordingly con the controller. I can see with Wireshark that the mDNS requests and answers are transferred between VLANs, but as already stated here, the process seems to corrupt the packets so that the clients won't be able to discover the printers (discovery by a client works only if the client is on VLAN2).
Here is a mDNS answer I see in Wireshark from a printer I want to add when the client is on VLAN2 (the printer is correctly discovered by Windows 11):
And here is what I get if I am on VLAN1 with the mDNS repeater enabled (the printer is not discovered by Windows 11):
Notably, we are missing the "Additional records" where the IP address of the printer can be found.
Is any fix for this issue coming up...?
