Hi! Same exactly issue found. For more reference what I did:

• Start podman rootful machine on WSL2
• Manually start DHCP proxy in podman's WSL2 distro: sudo systemctl enable --now netavark-dhcp-proxy
• Create network podman network create -d macvlan -o parent=eth0 maclan

When attaching container to network the I find same error that @avlec found:

>podman run -d  --network maclan nginx
Error: netavark (exit code 1): unable to obtain lease: dhcp proxy error: status: Aborted, message: "Timeout: Timeout", details: [], metadata: MetadataMap { headers: {"content-type": "application/grpc", "date": "Wed, 13 Mar 2024 09:18:26 GMT", "content-length": "0"} }

Output of podman inspect <network-id>:

Seeing the same issue does anyone have a fix for this?

@mwoodpatrick if you can reserve a fixed range of IP addresses on the LAN you can work around this with a ipvlan network this is the easiest.

e.g., the interface I want to use is eth1 which maps to some windows NIC and I have IP addresses in 192.168.1.64 through 192.168.1.127 I can reserve on the LAN for this podman network.

podman network create --driver ipvlan --opt parent=eth1 --ip-range 192.168.1.64-192.168.1.127

You can also do this by creating an ipvlan without the --ip-range but you have to change --ipam-driver in the network create command so it doesn't try to use DHCP (I'm not sure if you should use host-local or none for this). This will let you individually assign IP addresses to containers that you must then provide on the podman run you use to create the container (e.g., podman run --ip 192.168.1.64).
