In your data directory you will find a file called pg_hba.conf - the
entries in there determine who can log in from what machine with what
sort of authentication.

There are plenty of notes explaining it in the file itself or you can
find explanations in the docs -
http://www.postgresql.org/docs/8.1/static/client-authentication.html

you will probably want to add something like -

# TYPE DATABASE USER CIDR-ADDRESS METHOD
host all all 192.168.2.0/24 md5

and maybe -
host all all 127.0.0.1/32 md5
