I have added rules to allow a certain IP address access to port 80 which is redirected to an internal host. Now, this doesn't work whatsoever from a Windows 2K or XP machine, if I type the hostname or IP address in IE6 I can see the packets going back and forth fine but nothing is displayed apart from the "Server or DNS error" bit. If I telnet to the host port 80 from the Windoze telnet client, I just get "Connecting to x.x.x.x....", once again I can see the packets going through the firewall fine (I have maximum logging setup here ;) ). Fair enough, sounds like a misconfig somewhere. But Im convinced everything is fine.. so I reboot the WinXP box and boot into FreeBSD (they both have the same IP address). Now, using netscape, telnet, lynx I can connect perfectly ok to this IP address, and have the web page displayed, which is the odd part! It is definatly not a setting on the windows client, but Im really scratching my head over this one as I cannot see any reason for the webpage not to load, especially when it works fine from any UNIX shell around the world! FYI I am running FreeBSD 4.6-STABLE #0: Tue Aug 13 16:31:04 BST 2002. Grateful for any insight anyone could give me on this rather bizarre issue. -- Jamie Heckford Network Manager Trident Microsystems Ltd t: +44(0)1737 780790 f: +44(0)1737 771908 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
