Can't transfer files or use voice or video

-----Original Message-----
I have 2 computers connected to DSL with the Linksys
BEFSR41 (I have the newest firmware). Buth computers are
very similar in hardware.

One works perfectly with Windows Messenger (I can send
files, have video conferencing, etc).
The second one lets me chat but I can't transfer files
nor have video conference. The error I get is "can't
send
file, connection is blocked".

I checked and as far as I can tell the configurations on
both computers seem to be the same. Is there something
I'm missing? Anyone has had this problem before?

Thanks,
Daniel

daniel, usually with a router you have a DMZ
demilitarized zone. that opens up your router to allow u
to recieve things. the problem is that usually, you can
only enable the dmz for one computer at a time. you have
to specify the ip address for the one you want it enabled
for and like i said, u usually can only do 1 at a time.
check the "advanced" settings on your router config,
should see like, firewall...dhcp...and dmz. click the dmz
and see what it says. hope that helps u.
