With out knowing any thing about what "... the web interface ..." is I
can't say any thing about where you are at.
However your rules look like they are doing the DNATing (presuming that
your ""external IP is 192.168.2.2) properly (presuming that
192.168.1.<something> is your internal IP). However you are not doing
any SNATing to hide the fact that your internal LAN clients are being
redirected back to the the internal server when they try to reach the
external IP.
