/etc/shorewall/rules should contain something like this:
# redirect incoming http requests to internal web server:
ACCEPT    net    loc:10.1.1.1:80    tcp    80    -    1.2.3.4
ACCEPT    net    loc:10.1.1.2:80    tcp    81    -    1.2.3.4
#
# redirect incoming ftp from 4.3.2.0/24 to internal ftp server
ACCEPT    net:4.3.2.0/24    loc:10.1.1.2:21    tcp    21    -    1.2.3.4
#
