Hi,<br />
<br />
We have a current network as attached, running Windows 2003 Server, Exchange, SQL and ISA 2004, we do not want to use the ISA for VPN, but 2 Watchgaurd VPN Boxes, I have setup the Watchguards witha VPN tunnel between the two sites, but the ISA Complains about the 192.168.8.0 network, could you please guide me or point me in the right direction, to setup the ISA to except the 192.168.8.0 Network and allow me to acces the resources on the 172.16.8.0 Network.<br />

Hi,

We have a current network as attached, running Windows 2003 Server, Exchange, SQL and ISA 2004, we do not want to use the ISA for VPN, but 2 Watchgaurd VPN Boxes, I have setup the Watchguards witha VPN tunnel between the two sites, but the ISA Complains about the 192.168.8.0 network, could you please guide me or point me in the right direction, to setup the ISA to except the 192.168.8.0 Network and allow me to acces the resources on the 172.16.8.0 Network.


ISA 2004 VPN to VPN Router Configuration

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.

Software Firewalls

Microsoft Forefront, formerly known as Internet Security and Acceleration Server (ISA Server), is a network router, firewall, antivirus program, VPN server and web cache that runs on Windows servers. It includes identity management and protection systems, and discontinued systems for threat management and network protection, along with protection for Sharepoint and Exchange. The scope of discussions includes forward and reverse proxy, application and service publishing, virtual private networks (VPNs), outbound access rules, SSL certificates and network routing within either a single node or an highly-available array pairing.

Microsoft Forefront ISA Server

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.
