Fella's: This is my scenario: a firewall with three interfaces, one directed to the Internet, another to the DMZ and another to a proxy (Squid) transparent that is in front of a LAN. I don't have and I don't specify a server DNS (bind) in execution. In my DMZ I have the Web Server with Apache and Interbase. I have a system made in PHP, the users of the LAN consent to the system. Until there everything it is in operation, but the access to the system from the LAN it is terribly slow, it works but it is extremely slow. The normal pages with extension html or htm, are executed very quick, but my system PHP, not. I was seeing the logs of the SuSEfirewall2, and seemingly the first proxy goes to the Web to look for the system PHP and then newly to my DMZ. Don't I know if I was the sufficiently clear thing to expose the problem, but is it lacking some rule in the firewall? for where I begin to look for the solution? Thanks in advance Ernesto
