The guest vm in PVE can ping the other two PVE node (same config as this PVE node) ip. But cannot ping the gateway ip: 10.0.0.254

hi,

you need to enable promiscuous mode / mac spoofing on esxi and then it should work (this holds true for many nested virt setups e.g. hyper-v)

hi oguz,

Thanks for your reply. The promiscuous mode / mac spoofing are already accepted.

does it work with the default bridged setup?

No. Default bridged setup also not working.

No. Default bridged setup also not working.

can you show the network configuration again with this setup? should look like this [0]

try running a tcpdump on your PVE node to see if the pings from the VMs are going out:

tcpdump -envi ens33 icmp

and then ping from inside the VMs to the gateway. if you see the ICMP packets going out of the PVE node then the issue is elsewhere
