Question regarding new OpenVPN in 23.7

[omrij]

Hi
In past version, we could select which interface to bind, in the new version we must specify IP?
I want to bind to wan IPV6 which change every time I reconnect, what should I do?

Also, what option(s) do I need to select in "redirect gateway" to redirect (push) all traffic (IPV4+IPV6) through the VPN?
When selecting more than one option, the server fail to start.

Thanks
