PING: transmit failed. error code 1231.

-

i have hyperv environment set on laptop. within hyperv's virtual network manager, have created 3 network connections, 1 external, 1 internal no vlan id, , internal vlan id = 2.

i have vm network adapter set external connector. (i've tried internal connectors, too).

if ping ip, result:
ping: transmit failed, error code 1231.

host networking configuration
lan connection
* microsoft virtual network switch protocol
* internet protocol version 4 (tcp/ipv4)

on sharing tab
* allow other network users connect...
connection: local area connection 3
 (local area connection 3 virtual adapter external connector.)

i've tried sharing unchecked.

what missing?

thanks!

in nutshell - have broken virtual network.

when using external virtual network - not assign ip physical nic (in network connections).

here happens.

when external virtual network created - hyper-v inserts virtual switch in between physical nic , parent partition.  parent partition given new virtual nic can still traffic out port.
the external network switch allows traffic exit physical pc.

if create virtual network (any type) and set vlan tag within properties of virtual network - sets vlan tag on parent partition traffic passes on virtual network - not apply guests.

if running wireless on laptop , vms share in external network traffic, process totally different.

this extrapolating attempting do.
