Even on a firewall that proxies all of these, you're talking 25 or so proxies for H.323 and 5 (whiteboarding, file transfer, chat, etc.) for T.120.
At which point I gotta break out the old joke Fred and I used to share, circa 1992: Q: "What do you call a firewall that proxies HTTP, telnet, ftp, rlogin, ping... etc..?" A: "A router." Whiteboarding? File transfer? Chat? Why not remote disk format and install, too? I'm sure there are no security flaws at all in any of those protocols or the implementations thereof... This whole firewall "thing" has become an exercise in wishful-thinking "have your cake and eat it too" -- and in the long run it's not going to work. It only works now because the hackers aren't as smart as they and the media think they are. mjr. _______________________________________________ firewall-wizards mailing list firewall-wizards () honor icsalabs com http://honor.icsalabs.com/mailman/listinfo/firewall-wizards
