2 lan ethernet installed, one connected to internal LAN and other one connected to external LAN such as internet in which it is attached with ADSL Router i.e. DLink 502T. The net was working fine, but when install ISA Server 2004, i have choosen 3-leg perimeter, the installed firewall client was working fine with net, but when on same system i.e. isa server 2004 installed, the net is not working, however all microsoft site such as windows update, etc are working fine, all other than microsoft site are not coming. But when i have configure web proxy setting in browser, some specified sites are coming. why it happen so, i want all sites are allowed to be access on server itself only.
i m still unable to access anything net other than microsoft site , the error msg is " Error code: 403 Forbidden. The ISA Server denied the specified Uniform Resource Locator (URL). (12202) . can u provide any link how to get it working.
You should not install the Firewall client on the ISA firewall itself. If you have, remove the Firewall client from the ISA firewall device.
Hi Tom, I have not install firewall client on the isa server itself, only on client in which they r able to access the net, but on server itself, it is unable to access any site other than microsoft's. is it require to use webproxy setting i.e. put the ip address of isa server in browser to access the net?
