SG UTM on XCP-ng 7.6 Hypervisor dropping traffic

Scott Noel-Hemming

Looking for suggestions on how to find the cause of tcp communication failures.

 

I have some systems running "behind" a DomU SG UTM Firmware version: 9.714-4 on a XCP-ng 7.6 hypervisor with an AMD Opteron 6220 CPU. Everything works fine. Specifically, my backup software is being NATed through the UTM.

 

When I migrate the UTM to a XCP-ng 7.6 Hypervisor running on an AMD EPYC processor, the same TCP backup traffic drops the connection. The ONLY change is moving the UTM to the new hypervisor.

    What NIC does your hardware have?  Are you seeing any up/down messages in the Kernel log?  Is it specific TCP traffic, i.e., port 80/443?  Is it a custom TCP port?  Can you paste some errors from the log files?
