Shorewall users - Aug 2003 - what is the syntax for MASQ to masq differently via ip

I originally set up my masq file to have just one masq for all out going
traffic now I need to have its so the traffic originating from one ip
address is masq to a specific address and the rest as another.  Here is
my current config:

 

#INTERFACE              SUBNET          ADDRESS

eth1                    192.168.121.0/24                66.92.122.190

I would like something like this but couldn''t find the syntax in the
masq file or the archive can this be done:

 

#INTERFACE              SUBNET          ADDRESS

eth1                    192.168.121.0/24                66.92.122.190

eth1                    192.168.121.15                   66.92.122.185

eth1                    192.168.121.11                   66.92.122.184

Thanks for any guidance.
