Again; you're asking ISA to perform as a router.
Win2K has some basic routing abilities, and installing RRAS as a LAN router 
will certainly help that, but in order for the hosts to use the Win2K/RRAS/ISA 
server as a router, you'll have to :
    1. install two separate internal NICs 
    2. setup each NIC for operation on each subnet (no default gateways)
    3. install RRAS as a LAN router (no NAT)
    4. run http://jalojash.org/isascripts/rras_fix.vbs on the Win2K/RRAS/ISA 
Server
    5. set the ISA internal IP as the default gateway on each and every 
internal host that expects to use ISA as the router between subnets.
..and then, there are no guarantees...

  No i wish i could use ISA as router....... both segments are on the same 
network switch but of course they cannot see each other. I was trying to find a 
way to use ISA as router.
  Another chance could be adding a network adapter for the new segment.

    You say "new segment"; can each segment see each other without ISA?
    ISA is a poor router; it's not designed to function that way.

      I have a 3 homed DMZ working perfectly since last autumn. Now i need to 
gain access to a different internal subnet from my internal network ex: all my 
computers are on 192.168.1.X and i should connect a 10.1.0.x network. I have 
inserted that renge into LAT and added a 10.1.0.X address to my internal 
interface( it was 192.168.1.1 and now has also 10.1.0.10). The routing table is 
added correctly but i canno reach that segment.
      WHat is the problem?


      thanks in advance
