Where there is an allow statement, anything not allowed by allow statement(s) in the pool will be denied - and similarly with deny statements and anything not denied is allowed.

I've successfully mixed allow and deny statements in the same pool.

- Any client matching a deny statement is denied.
- Any client matching an allow statement (but no deny statement) is allowed.
- All other clients are denied.
