Internet connection existance with more than one proxy
At work,we have got ISA 2004 (FQDN: proxy.rami.ae,,,,,fake name ) which has two interfaces,
NICA 192.168.1.250 connected to core switch 4500
NICB for DMZ area ,,192.168.101.294
From DMZ through PIX to outside world.
I believe that all internal PCs (workstations) go to internet through ISA, the reason (Is it right conclusion ? ) I am saying that because we have to configure proxy within Internet Explorer -- > Internet Option Ã* Connection Ã* LAN setting
proxy,,,,,,,,,,,,,,,,,,port 8080
Some times when there is lack in the internet connection , I changed the LAN Setting to :
proxy1.telecomm.net.jp (fake one),,,,,,,,,port 8080
And some times If I chose the option :,,,,,,,,,,,,is this some thing related to a browser cache ?
“ Automatically detect settings “,,,,it worked as well
How can we troubleshoot (step-by-step) that ? (i.e how can we force in PCs use the right proxy ?)
