Hi, I am trying to use Tomcat 3.2.1 on my NT 4 server with IIS 4 and Microsoft Proxy Server installed. Now Tomcat is working fine with iis via localhost so I can access http://127.0.0.1/examples/jsp/index.html or http://127.0.0.1:8080/examples/jsp/index.html. But I can't make it accessible via its two ip addresses: 10.XX.XX.XX or 66.XX.XX.XX. BTW, 10.XX is a fake address we used for internal network and 66.XX is got from ISP by DHCP. I also tried Sun JSWDK 1.01. Same thing. Any ideas will be highly appreciated. Thanks a lot for your attentions. Sam
