I have close to the same problem.
I am running a Linksys router and XP Home, I have dropped all the firewalls (I hope), and can send a file to a friend, but he can not send to me.
He has XP and a dial up connection and says any firewalls he could find are down.
We can type meassages back and forth with no problem, he just can’t send me files??

We have tried match our ICQ setting and that didn’t help, we’re not sure at what end the problem lies.

We’re wondering if ICQ needs its own port on my router and ifso, how?
We’re both more than a bit computer illiterate, so any help would be most welcome.

I have looked though the past posts and tried what I could understand, but still no luck.
Anybody??
TIA
