VMware Remote Console gets frozen randomly…

[oxyle]

Hi everyone,

I've got the following issue regarding my homelab, using pfSense 2.3.4:

My setup is the following:

• 2x DL380 G7's running several VM's. (both HP images 6.0u3)

• vCenter 6.5b

• pfSense being hosted by one of the above hosts.

Networking:

• VLAN10: My network for end-users with laptops/phones/tablets.

• VLAN11: Network for all my (virtual) servers including vCenter, and ESX.

At this moment pfSense allows ALL traffic between VLAN11 and 10.

My problem is the following:

• If I connect to my vCenter using it's management IP within VLAN11 I can connect, which is fine. I can set up HTML5 (web) consoles to all my VM's which is all good.

• If I connect to a VM using the VMRC that is being hosted by one of the ESXi machines in VLAN11 I get random freezes when there are animations (scrolling, browsing folders) on the screen.

However if I try to connect to my hosts on their management IP's in VLAN10 (no routing needed here) I experience no freezes at all. I tried running Wireshark and I see some connection resets going on, when my issue occurs. However I am not certain on how to fix this.
This is getting very annoying since I am not able to use VMRC's at all now when needing to configure something.

I've tried to run Wireshark regarding my issue and this is the output I get every time I run into this issue:

Does anyone got any idea about this? I had a old Sophos XG VM lying around and booted up that once, to check if the issue still persisted and it didn't at all. So this seems a pfSense issue somehow. And yes, all VM's have the latest VMware Tools installed!
Thanks in advance!

Just an update:

I've reinstalled a completely new virtual machine and my issue keeps persisting…

Anyone at all being able to shine a light on this issue?

I've reinstalled pfSense from scratch multiple times right now, tried all sorts of network adapters within VMware.

None have helped, and it's getting really troublesome in a homelab right now. I've tried Sophos XG and the issue doesn't persist in that system, but some functionality is key in my pfSense VM…

What if you power off or disconnect one of the esxi machines? Do you still have the same error?

[oxyle]

Yes! I even reinstalled both of the hosts (and their datastores)!

Even on 2.4.0 the issue still persists!
