I have a similar situation. I have OPT1 connected to a wireless access
point, and wireless clients in turn connected to that. I have rules to only
allow DNS and PPTP access to the m0n0wall from OPT1, and deny everything
However, connections from LAN -> OPT1 seem to continue to work fine, even
things like VNC. As it happens I find this quite useful - LAN can access
OPT1, but not vice-versa. But if you wanted to prevent it, I guess you'd
want a LAN rule denying all traffic with a destination of "OPT1 subnet".

I would also be interested in this. Perhaps an extra option under interface
choices or a predefined alias called "m0n0wall" or something like that.
It'd be good if one could define an alias to encompass all m0n0's Ips (bear
in mind there are 3 of them - WAN, LAN and OPT1). At the moment, my OPT1
PPTP rule has to be repeated twice, since someone could connect either to
the LAN IP or the OPT1 IP, equally successfully.
