Not gonna say I'm a guru by any means... as-needed hacker maybe? :)

Not knowing what ports are needed, but by your script it might look like the 
range 1718-1820 assuming you already know those are the ports needed for your 
app.  I did something similar in the past with DialPad.com.  I didn't need quite 
the range of ports though.

# This allows access with DialPad
/usr/sbin/ipmasqadm autofw -A -v -r upd 51200 51201 -c tcp 7175
/usr/sbin/ipmasqadm autofw -A -v -r tcp 51210 51210 -c tcp 7175

Plug your values there and see if it works; good luck.
