Just a question. How does remote-override differ from ip-remote-hint?
Both options seem to have the same effect aside from very subtle
differences. Perhaps we should add this as an alias for the already
existing option.
They are different options.
ip-remote-hint is used when the app driving the client via management
interface has already done a DNS lookup on the remote address, and wants
to save the OpenVPN core from having to do a redundant lookup.
remote-override is used when the client UI has an option that allows the
end user to override the default server address. For example a UI might
give the user a drop-down list of regions to connect to. Since it is
common in OpenVPN configs to have a list of many "remote" directives for
failover, we needed a directive that would do a "search/replace" on the
hostname component of each "remote" item.
That's different from the approach of ip-remote-hint which is designed
to only provide a DNS resolution hint for the first "remote" item.
