I dont know why the forward function doesn't work.

[silveric10]

I only made these changes below to the unbound.conf. I want to forward all my dns queries to port 9999, but it doesn't work.
interface:127.0.0.1@8888
forward-zone
name: "."
forward-addr: 127.0.0.1@9999
Can you help to explain?

You need the option do-not-query-localhost: no in unbound.conf.
The previous default value was yes and this prevented messages to 127.0.0.1 from the forward-addr.

This seems a legitimate question for the Unbound mailing list, not a bug report. — Benno

The commit above makes unbound-checkconf print out warnings for the matter, since other people also experience this as a surprise, I thought that could be helpful. Looks like this:
unbound-checkconf: warning: forward-addr: '127.0.0.1' is specified for forward-zone: '.', but do-not-query-localhost: yes means that the address will not be used for lookups.
