Hey there, The new network-manager in disco does connectivity checking per-device/connection type which doesn't play nicely with th rp_filter=1 default that procps sets in Ubuntu
The details of the discussions in https://gitlab.freedesktop.org/NetworkManager/NetworkManager/issues/116 but a summary is 'it uses libcurl and binds the HTTP request to the device, using the SO_BINDTODEVICE socket option. rc_filter=1 rejects all incoming packets, if the sender wouldn't also be reached via that device. It thus counteracts SO_BINDTODEVICE.' Basically those are conflicting so we need to either disable the connectivity checker or change the rp_filter default. It looks like systemd upstream and fedora already decided to change to default to rp_filter=2 (loose) https://github.com/systemd/systemd/commit/230450d4 Can we do the same in Ubuntu?
