Hello. Im running XP with Messenger 6.1
I have today installed a Belkin 4 port Cable/DSL Gateway router model
F5D5231uk4

Everything works fine except I cannot send files of any type.
I know ports of 6891-6900 need to be opened but Im not sure I am doing it
right in teh router set up screen.
Any advise / help would be appreciated
