Hello all, I am new to ISA, however i have setup a VPN on ISA server and can make remote connections to my private network over Internet using build-in vpn client on Windows XP. However since some of our clients use different operating systems (such as 2000/ linux/ pocket pc and etc) i wonder if there are other 3rd party vpn clients used to connect to the ISA vpn? In short, can i only use built in MS vpn client to connect to the ISA vpn or are there any other vendors who provide compatiable vpn clients to connect to the ISA (such as cisco vpn clients or nortel vpn clients?) Is there anybody else over there using a different vpn client to connect to the ISA? thanks for your efforts in advance, Emre.
