hi, Ok. Not even pings do not work any more. The problem seems to be in layer2. One virtual machine sends out the ARP request: 10:04:08.843007 08:00:27:4a:7b:e5 > Broadcast, ethertype ARP (0x0806), length 42: arp who-has 172.19.93.1 tell 172.19.93.2 the other virtual machine get it and answers it: 10:04:12.375772 08:00:27:4a:7b:e5 > Broadcast, ethertype ARP (0x0806), length 60: arp who-has 172.19.93.1 tell 172.19.93.2 10:04:12.376569 08:00:27:a9:3c:3a > 08:00:27:4a:7b:e5, ethertype ARP (0x0806), length 42: arp reply 172.19.93.1 is-at 08:00:27:a9:3c:3a But the answer packet never reaches the first machine.
