Problem Yahoo! Messenger File Transfer

[Anggi Lesmana]

Dear Ubuntuers,

I have unique problem with iptables & squid configurations,
Example :

Comp A : 00:21:91:00:2A:C8 (by mac-address)
Service Allowed : Yahoo! Messenger also Yahoo! transfer (send & receive)
files, not allowed to browsing HTTP

3 IPTables chains are DROP

I opened that mac-address to access these yahoo messenger list :

That computer could sent file, but didn't to receive anyfile from Yahoo!
Messenger transferfile.

The problem also is when I opened port 80 (YM transferfile) to any
destination, send & receive YM File Transfer were worked, but it was
browsing to Internet.

Any suggestions?
Thanks
