Multipass instance can not be started while F5 VPN is on about multipass HOT 6 OPEN

Hi @CharlieYu12345

VPN's are known to play havoc with Multipass' networking. Because we can't account for every kind of VPN configuration and we don't believe we should be changing your configuration for you, we don't directly support the use of Multipass with VPNs.

However, we do have some documentation on the topic here and here, and I would recommend taking a look at that first.

If that still doesn't work for you, let us know!

Thanks @sharder996,
I have tried the

Not sure if this is a workaround or solution, but I was able to make this work by nat-ing the multipass bridge with my vpn interface.

I added nat on utun1 from bridge100:network to any -> (utun1) to file /etc/pf.conf. Then I reloaded the file: $ sudo pfctl -f /etc/pf.conf.

(Just built my first snap on mac 😃)

It does not work, because my mac has no nat command.

nat is not a command that you execute in your terminal. You need to edit the file /etc/pf.conf by adding the line

nat on utun1 from bridge100:network to any -> (utun1)

and then reload the file with the command sudo pfctl -f /etc/pf.conf

It is explained in full here:

from multipass.

I tried the following actions, still not working:

1. Disable VPN
2. Use OnyX to clean all cache.
3. Reinstall multipass.
4. Restart OS
5. add ant line into /etc/pf.conf succucefully

Thanks.

Hi @CharlieYu12345, can you confirm whether or not you can launch and connect to instances when your VPN is disabled?
