Comment 7 for bug 2041825

I'm adding a wireguard config by hand..

- add the private key as generated by 'wg genkey'
- add the peer (endpoint, public key, allowed ip's)
- set up ipv4 (manual; address/mask, dns)

if at this point (before saving) you select "automatic", it allows you to save but it isn't actually saved as mentioned originally. But if, instead of saving, you select "manual" again, it *doesn't* let you save unless you change some of the previously entered values.
