I work behind a very restrictive firewall too, and we (people in my org) realized that the communication in all the clients is happening over http. The clients "tunnel" their protocols over http and hence it works.
If you use gaim, you may want to go to advanced settings and try giving port numbers as 20, 23 and 80 to see if yahoo, gtalk and MSN start working.
Thanks for the interest. But I had tried this in the past and I tried it just now. Does not work. GMail (on GAIM) simpy said 'port x tunneling not allowed', while Yahoo (on GAIM) gave a 'write error' for port 80. Other messages were the same for GTalk.
GAIM would start working out of the box, if the ports are opened. I know this since the ports were opened temporarily and they just worked.
From Gaim FAQ :
Yahoo!'s firewall with no proxy option connects to Yahoo! by wrapping the YMSG protocol inside HTTP. Gaim currently doesn't support doing this.
So no luck for you Rishi. Yet.
