I have installed RHEL 5.1 and have the following result with the following configurations. Conf-A. ADSL Modem--->Windows // It offers fast response.... when connecting any website Conf-B. ADSL Modem --> Linux--> Hub--->Windows Client ... // Slow response compared to Conf-A .... when connecting any website Conf-C. ADSL Modem --> Router --> Linux ---> Hub --> Windows Client .............. // Fast response and same as Conf-A. Note: 1. All above configuration are test without squid (i.e with NAT only mode ) 2. Selinux -- Permissive mode Conf-A & Conf-C response time are fast and i think same... Here is my questions... !! Why it becomes slow response time with Conf-B style configurations... ? If any one of you suspect, pls test by yourself. I think ... we need to makes some tweaks... in Linux box... But I dont know ... May be MTU...Selinux.....or sth else... I believe any one can point out me how to fix Conf-B to get fast response. Mr.Crack007
