OpenVPN custom option for "--client-to-client" causes configuration error
Closed, InvalidPublicBUG

Description

Hello,

I am configuring OpenVPN. When using the configuration command

"set interfaces openvpn vtun0 openvpn-option "--client-to-client", after rebooting VyOS reports a configuration error and clears the OpenVPN configuration. For some reason this shows up as "unquoted" in the configuration file.

Thanks

Hi -

I will close this. It turns out the root cause is related to this other bug I filed:
