Although this might seems extremely simple for you guys, I have issues in letting my Two Windows VMs see each other on Proxmox,

Here is my configuration, pretty much default:

auto lo
iface lo inet loopback

iface enp1s0f0 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.1.10
netmask 255.255.255.0
gateway 192.168.1.1
bridge_ports enp1s0f0
bridge_stp off
bridge_fd 0

Setup:
  • my proxmox server is running ip: 192.168.1.10 (directly connected to the SOHO router)
  • my 1st VM is: 192.168.1.11
  • my 2nd VM is: 192.168.1.12
  • all: /24
  • no firewall
  • using Virtio with drivers installed (but also tried, default intel)
Test:
  • from the VMs I can ping anything on the outside: proxmox server, my laptop, the router, google dns etc.. but can't ping the other VM.
  • from an outside connection (laptop on wifi) can ping everything but not the VMs.

tracert just times out

I am sure it is something extremely simple I am missing here :)
