For some reason that only God knows (and some of you) the Squid 2.5 stable something from RedHat (last version available) it is not working. It is not respong from outside (internet). I have to admit: Squid is to much for my poor knowledgment. As my network is quite simple, 1 Win2K server (192.168.0.10 fixed)+IIS, 1 Linux RedHat (192.168.0.11 fixed)+Apache+Squid, router (192.168,0,1) and Dynamic IP provider. 1- My problem: To have IIS and Apache responding both to port 80 - The both servers have several virtual sites and I can't use port 81 ou similar. questions: 1- Do I need to use Squid to solve my problem? 2- Do I need to config DNS server? 3- Do a good soul has a squid.conf file that match or close of my needs? Or have a similar problem? Tears Nestor
