new-hsnnetwork / wireguard - An adapter was not found.

[albertkohl-monotek]

Hello, i'm trying to add a windows node to a working k8s multi-cloud cluster. my current linux nodes all work over a wireguard vpn, on bare-metal ubuntu boxes. while trying to add the windows node my main issue seems to be that i cannot create HnsNetworks on the vpn interface.

the wireguard ip is: 10.0.0.8, the ethernet interface is 192.168.3.122
Invoke-HNSRequest Method[POST] Path[/networks] Data[{ "Subnets": [ { "GatewayAddress": "192.168.255.1", "Policies": [ { "Type": "VSID", "VSID": 9999 } ], "AddressPrefix": "192.168.255.0/30" } ], "NetworkAdapterName": "wg0", "Name": "External", "Type": "Overlay" }]

any pointers would be helpful. Thanks!

Facing the same issue when trying to create an overlay network, and the server is using NIC teaming with more than one interface.

PS C:\usr\local\bin> $JsonString='{"Name":"External","Type":"Overlay","Subnets":[{"AddressPrefix":"192.168.255.0/30","GatewayAddress":"192.168.255.1","Policies":[{"Type":"VSID","VSID":9999}]}]}'
PS C:\usr\local\bin> Invoke-HnsRequest -Method POST -Type networks -Data $JsonString
Invoke-HnsRequest : @{Success=False; Error=An adapter was not found. }

I face this only when there is more than one interface on the NIC team

PS C:\var> Get-NetLbfoTeam

Name                   : Prod
Members                : {NIC2, NIC1}
TeamNics               : Prod
TeamingMode            : SwitchIndependent
LoadBalancingAlgorithm : Dynamic
Status                 : Up

With one interface NIC Team, the issue is not seen. Is there any setting for HSN when using NIC teaming?
