VMs do not connect to the network external to proxmox

[marlon.costa]

I'm virtualizing proxmox in vmware, because I don't have hardware available for testing.

I access the proxmox GUI normally, I create two Ubuntu vms in the environment, they talk to each other, but the two do not go out, both the proxmox host and the vms are on the same network.

The VMs ping the proxmox host.

HOST:



VM01:



VM02:



any ideia?

Can the VMs ping the default gateway 10.20.4.1?

If you run tcpdump on the host, do you see the ICMP packets? If so, only the outgoing ones?

tcpdump -i vmbr0 icmp

You probably need to install the tcpdump tool: apt install tcpdump.

they have no response from gateway 10.20.4.1, according to tcpdump prints.

Yeah, looks like they go out, but never get a reply.

Did you check that the router also has the /16 network setup correctly? No firewall rules that would prevent it or anything like that? Do you have other machines in the /16 network? Try pinging those to narrow down what the actual cause ist

I'm virtualizing in VMWARE for testing, I had to create a new port group with the options below, now my VMs communicate with my entire LAN, but they still don't communicate, nor do ping and SSH.
