Hi Jacky,
 
What do you mean by only pc that use isa server as a gateway can ping?
In order to connect to the ISA Server firewall/VPN server in the back to
back ISA Server firewall DMZ setup, you need to take advantage of VPN
passthrough, where you tunnel inside an established tunnel to the
external ISA Server firewall.
 
Thanks!
Tom

        Yes but the method is not working successfully only pc that use
the isa server as a gateway can ping and those who use different gateway
are unreacheable.
        If you know the solution please send me a walkthrough on how to
configure it. TQ

                Hi, i have encountered a problem in setting up the vpn.
The problem that
                i
                encountered is i can ping the external network pc that
set their gateway
                as the isa server but not the pc that set their gateway
to cisco router.
                All the ip is same only different gateway. Can anyone
tell me what is
                the
                problem and how to solve it?
