I have found that using a config file makes it easier to 
make changes to your natd configuration.
Create for example /etc/natd.conf, which in your case could 
contain something like this:

interface <if name>
use_sockets yes
same_ports yes
redirect_port tcp 192.168.0.130:2050-2051 2050-2051
redirect_port udp 192.168.0.130:2050-2051 2050-2051

Start natd with 'natd -f /etc/natd.conf'.
You could then add or remove options whenever you want, just 
edit the file and -HUP natd.
