We have fresh installed WS2019 on physical blade. That blade has two 10Gb network adapters. When we set up one of them (Ethernet4 or Ethernet5), ping is working fine in VLAN. After we set up NIC Teaming, ping is not working, but we have connection to other server to proxyserver etc. We try ping default gateway even proxyserver with error "General Failure". From other devices to WS2019 ping is working. Ping is not working even on L2 network layer. On our VLAN we have permit any any and Firewall turned off. The last picture is output from "netstat -nr".
