Proxmox 8 breaks nested ESXi vmxnet3 connectivity

[virtiocom]

Hi,

I had ESXi VMs on proxmox 7 working fine, but after upgrade to proxmox 8, the vmxnet3 vnics perform DHCP but I'm unable to ping them.

I tried to boot with 5.15.131-2 kernel but no difference.

Happened to anybody else?

Best regards.

Hi @virtiocom,
I have a similar issue after upgrading from 8.0.4 to 8.1. See here.

Don't have DHCP in use, but something changed, but I couldn't find out what exactly.

I have the same issue: I can ping from external connections, but other hosts within the same Proxmox environment cannot be pinged. Additionally, there seem to be various connectivity anomalies both internally and externally.
