Hi All

Currently i am using ISA server 2004 as edge firewall. Now we want to install juniper SSG5 firewall and the internet connection will be terminate on juniper firewall. The isa server 2004 will be connected with the juniper. We want that all the users should be connected with the ISA server as they are now connecting. ISA server will be doing the content filtering and passing the traffic to the juniper.
Please help me in this regard.

Regards.

Instead of assigning a public IP address to the ISA firewall's external interface, create a private network (that is separate from your internal network) and use that between the ISA and Juniper. Assign one IP address to the ISA firewall's external interface and another to the Juniper's internal interface. Assign the public (ISP) IP address to the external interface of the Juniper. The default gateway of ISA should point to the internal interface of the Juniper. Create an access rule to allow any traffic from the ISA firewall that you wish.
