Hi all, I have Infinilink i510 ADSL modem, was connection to my Cisco LAN switch and giving the internal IP as 192.168.1.254. All my workstations use the ASDL IP as the gateway, ISP DNS and everyone sharing the internet. I install ISA on WIN2K, with 2 Ethernet cards, one giving local IP 192.168.1.2 connect to my LAN, the second as dynamic (DHCP) and connected to the ADSL. I start with http://www.isaserver.org/pages/tutorials/setting_up_machine_before_isa_i nstalltion.htm And http://www.isaserver.org/pages/tutorials/adsl_setup.htm I have DC as 192.168.1.1, The ISA can not see the ADSL, no matters what I tried, thanks in advanced.
