Em,

thanks, i deleted network that i just created, and added 172.16/16 to
internal network IP ranges.

added static route, and it works :)

p.s. i not mentioned but my external nic is connected to internet, and it is
not in same subnet...

The first problem you have is using the same subnet on the internal and
external NICs (192.168.1/24) .
They *MUST* be on separate subnets or ISA cannot function as a firewall.

The second problem you have is creating a new network to represent the
172.16/16. Delete this.

Hi,

I have ISA 2006, two NICS, external and internal with
(192.168.1.0-192.168.1.255).

In LAN i also have another router with IP 192.168.1.50 and network behind
this router (back-end network) (172.16.0.0-172.16.255.255).

So idea is, if LAN computer ( 192.168.1.20) want to comunicate with
(172.16.1.15) it will forward request to gw 192.168.1.254 (ISA internal IF
IP).

I created new network, network rule and access rule, so i should add static
route to ISA, that

172.16.0.0 mask 255.255.0.0 gw 192.168.1.50 ?

I see in some forums that i should put route gateway 192.168.1.254 and not
192.168.1.50, but i don't understand how will ISA know where to find
172.16.0.0/16 network?
