  • Can you tell more about "VM from other computers in network 10.10.10.0"? You should use tools like ping and tcpdump to see where packets are going etc. – A.B May 30 '21 at 08:51
  • I can ping only from VM to 10.10.10.0 and World. I cannot ping from any machine from 10.10.10.0 to VM. – Piotr Topolski May 30 '21 at 19:34
