No trafic to some VMs on HyperV failover cluster
Posted: Fri Apr 22, 2022 1:00 pm
Hi all,
I'm facing to a curious problem on our system.
We have 2 physical servers (WS 2019), hyperV both with failover clustering.
Some VMs are hosted by HPV-1, some others VMs are hosted by HPV-2.
DHCP Server is on DC1 hosted by HPV1.
Softether VPN Server is installed on HPV-1, native protocol through 5555 port, the local bridge is defined to VM Network interface.
The problem I'm faced is external clients well take DHCP address by DC1, connection OK, but:
- no trafic (ping or other) to VMs hosted by HPV-1
- trafic is OK to HPV-1 directly
- all trafic OK from and to HPV-2 hosted VMs
If I move VMs to HPV-2, all becomes OK again to all VMs.
I move VMs to their original location, trafic is KO for ones hosted by HPV-1.
I tried the following without any success:
- disable firewalls on HPV or VMs
- disable ESET Security also
- uninstall and reinstall SE
I really don't understand why trafic is not passing to hosted VMs by HPV-1. Seems a route issue but no idea...
Any idea would be really appreciated!
