Answer 1

We need to set Forwarding to be enabled across the two v-Switches. Using this command (with admin rights) based on my v-Switch names works.

Get-NetIPInterface | where {$_.InterfaceAlias -eq 'vEthernet (WSL)' -or $_.InterfaceAlias -eq 'vEthernet (Default Switch)'} | Set-NetIPInterface -Forwarding Enabled

Below is my network connection

Answer 2

That's a great command line ! Minor improvment that would product less logs, invoke Enabled only if state is Disabled.

Get-NetIPInterface | select ifIndex,InterfaceAlias,AddressFamily,ConnectionState,Forwarding| where {$_.InterfaceAlias -eq 'vEthernet (WSL)' -or $_.InterfaceAlias -eq 'vEthernet (Default Switch)'} | where {$_.Forwarding -eq 'Disabled'} | Set-NetIPInterface -Forwarding 'Enabled'
