Hi,

this is what I would do!
keep your policy very simple: /etc/shorewall/policy
loc     net    ACCEPT     all     all    REJECT

and specify what can come through in the rules files:
here you add this:

#ACTION  SOURCE               DEST               PROTO   DEST    SOURCE
#                                                        PORT    PORT
ACCEPT   net:121.121.12.11    loc:192.168.1.2    -       -       511

I hope this helped you!
Grtz,
Tom
