ISA Traffic redirection (rules/Policies)
Posted on 2011-03-08
We have ISA 2006 with 2 network interfaces configured as ( External : 10.0.0.2/24) (Internal : 10.100.1.5/22)
the company user's gateway is set as 10.100.1.5 that will make ISA decide if the user has access to the internet and let it out or not.
we have another gatway that is 10.100.1.254 (which is a Junipper firewall+VPN) and it is used to link our branch offices together.
the problem is that when i user tries to access a shared folder that is in a branch office (example 10.100.30.2 which is a server in a branch office), he cant because his gateway is 10.100.1.5 which is the ISA server and not the Junipper Firewall.
is there any way to make a rule in the ISA server that will see if the traffic destination in (10.100.30.x) it should forward it to the Junipper Firewall (10.100.1.254) and like that the user will have access to the shared folder in the branch office, and if the user destination is any thing other then 10.100.3.x then it should process it and let it throught the normal policies and then throught the normal interface (10.0.0.2)
