docker macvlan hosts stop working after kernel 5.4.11

[evilbulgarian]

Hi,

I have set up some pihole docker containers using macvlan network driver. After upgrade to my linux kernel 5.4.11, the hosts are accessible via the docker host but not from other hosts on the network like before. ❯ docker inspect wifi_172 [ { "Name": "wifi_172", "Id": "cc3809eb470525c3f6af4c01a1571be73e0902e6436006259cf664bf052cd7eb", "Created": "2018-04-03T10:37:21.975032167-07:00", "Scope": "local", "Driver": "macvlan", "EnableIPv6": false, "IPAM": { "Driver": "default", "Options": {}, "Config": [ { "Subnet": "172.16.6.0/24", "Gateway": "172.16.6.1" } ] }, "Internal": false, "Attachable": false, "Ingress": false, "ConfigFrom": { "Network": "" }, "ConfigOnly": false, "Containers": { "925f0389089fe6d290017d3d91c9cbdeb0e37967c21aca8d498bf20c4f421b80": { "Name": "wifi-hole", "EndpointID": "ce72a371ed63d8573faa0d9c914198b9f629a185e2cfa07d264797802aa28a4b", "MacAddress": "02:42:ac:10:06:fe", "IPv4Address": "172.16.6.254/24", "IPv6Address": "" } }, "Options": { "parent": "van0.172" }, "Labels": {} } ]
