As far as I know, Open Transport was introduced with System 7.5. I wonder if it actually works with older versions of MacOS? Have you tried the pre-OT networking that came with 7.1, like MacTCP? (But that does not seem to explain the IP address collision observation...)
For sake of completeness of this topic, I just happened to discover the same behavior with Dell switches:
Appletalk and Bonjour services are not working when connected to Dell Networking N series switch in a VLAN with IGMP snooping enabled
Thank you all for your comments and suggestions!
Looking forward, I wonder how this issue could be solved in the future? I am not a network expert (I actually learned quite a bit the last days...), but would it make sense if Netatalk did some sort of IGMP multicast group registration on the...
SOLVED -- IGMP Snooping has to be deactivated in Unifi network settings.
Here's my chain of try & error (and luck):
I logged into the switch via SSH and the commands --> "cli" --> "show mac-addr-table" and checked the MAC addressing table:

Yesterday, I disabled various functions on the Unifi switches, e.g. Threat Detection, Deep Packet Inspection, and (Rapid) Spanning Tree Protocol. The first two I assumed might only work on well-formed IP packets and especially Thread Detection & Prevention might discard everything else. I also...
Thanks both for the quick response!
I did a check with a MacBook running Wireshark connected to the hub with a Q800 + A/UX 3 + AppleShare Pro and iMac MacOS 9.2. ("Trawl" on the iMac can see both the Quadra and the iMac, and I can connect to the AFP share on the Quadra.)
When booting the...
I recently installed Netatalk 2.3 on Debian within a VM on an Intel Mac and tried to have my Classic Macs connect to it via AppleTalk over Ethernet using Unifi managed switches. Unfortunately, the computers could never "see" each other. I tried to narrow things down by setting up various AFP...
