Trying to share files in MSN messenger

I got SMC7004ABR Barricade router and I want to know what da heck this means...

-----------------------------------------------------------

Here is all the info we have on MSN Messenger:
MSN Messenger

NOTE: Shut off any personal firewall programs such as BlackIce, ZoneAlarm, etc.

Ports 6891-6900 enable File send,
Port 6901 is for voice communications

Allows Voice, PC to Phone, Messages, and Full File transfer capabilities.

IN TCP 6891 - 6900
IN TCP 1863
IN UDP 1863
IN UDP 5190
IN UDP 6901
IN TCP 6901

Try setting 6891,6900, and 6901 as triggers. Then set the public ports to 1863,5190-6901. If that does not work, set the incoming ports to 1-64535 (note: this opens a WIDE range of ports) and add in 5190 and 1863 as triggers. You can also try putting your machine in the DMZ (go into Misc. Items). Make sure that you have upgraded the firmware as well.

1.
Trigger Port #
and whether it should be TCP or UDP
2.
Public Port #
and where it should be TCP or UDP
