i have a problem enabling yahoo webcam on a NAT'ed drop-all-unless-specified firewalled box. currently the ym clients (all on win32's) can only access yahoo messenger via squid transparent proxy but this does not allow webcam to work. the requirements for yahoo webcam is that you have to open up TCP port 5100, i have done that but i still can't established a connection with the ym server. i was wondering if anyone here knows the complete rule for making this work. thanks. `` Sandy T.
