The docs were outdated mentioning the qemu backed for Mac and I find the way they are written to be a bit confusing. I think it is best to start with that this option is not supported on all the providers except WSL. Fixes: #26780 Signed-off-by: Paul Holzinger <pholzing@redhat.com>

#### **--user-mode-networking**

|
This option can only be used for the WSL provider on Windows. On all other
|
|
platforms this option is ignored and user mode networking will always be
|
|
`true` there because these providers always depend on gvproxy (our user
|
|
mode networking tool for the VMs)
|
|
|
|
In contrast, The Windows/WSL backend defaults to `false`, and follows the
|
|
standard WSL network setup.
|
|
Changing this setting to `true` on Windows/WSL informs Podman to replace
|
|
the WSL networking setup on start of this machine instance with a user-mode
|
|
networking distribution. Since WSL shares the same kernel across
|
|
distributions, all other running distributions reuses this network.
|
|
Likewise, when the last machine instance with a `true` setting stops, the
|
|
original networking setup is restored.
|
|
|
|
In some VPN configurations the VPN may drop traffic from alternate network
|
|
interfaces, including VM network devices. By enabling user-mode networking
|
|
VPNs observe all podman machine traffic as coming from the host, bypassing
|
|
the problem.
