On the Completing the New Network Wizard page, click Finish. On the Network Addresses page, click on Add Adapter, select Branch on select Network Adapter page and then click OK. On the New Network Wizard page, select Internal Network and click Next.Ĥ. On the Welcome to the New Network Wizard page, type Branch in the Network Name box and click Next.ģ. In the Forefront TMG console tree, Right Click on Networking > New> Network…Ģ. Perform the following steps to Create New Network for Branch:ġ. At last, create Access rule to control traffic. Here we willīranch Network TO Internal, LAN, DMZ as Route relationshipīranch Network TO External as NAT relationshipģ. First create new network for branch and give the name as your design. More than two NICs even if the Windows Server 2008 R2 recognizes moreġ. When we install TMG 2010 Firewall, by default TMG 2010 will onlyĭetect two networks, Internal and External. Then we have to add static route (all branch offices Internal Network) in TMG 2010 to reach branch offices network because TMG 2010 will not support dynamic routing.

Internal network addresses in the TMG Server on the Branch Network (NICĬard). In this scenario, we have to add all branch office Here we will focus on configuring TMG Firewall so that Head Office andīranch offices can communicate with each other over Intranet and the Branch offices use Cisco routers and are connected with head office using Cisco router with static routing and IPsec Site-to-Site VPN. They are named as Internal, Branch, LAN, DMZ and External. But most of the cases this Guru Mantra will work. Note: In the real scenario, sometimes we have to go beyond this Guru Mantra.

When the source Network use Private address and destination Network use Public address, then we can use a NAT relationship.

When the source and destination Network use Private addresses, then we can use a route relationship.Guru Mantra on when to use NAT or ROUTE relationship: Addresses from the source network are always translated when passing through TMG 2010 Server.The Source IP address is always preserved.

In route relationship, client requests from the source network are directly routed to the destination network.If a routed relationship is defined from Branch to Internal network, a routed relationship also exits from Internal to Branch Network.

Where networking relationships can be NAT or ROUTE. That define how network packets will be passed between networks orįor this, we should familiar with Network Rules of TMGĢ010.Network rules determine network relationships between two networks Multiple networks in TMG 2010 Firewall we must configure network rules Here, we will configure multi-networking in TMG 2010 FirewallĪnd it will remain same as in ISA Server 2004/2006.When we enable Multi-networking means that you canĬonfigure multiple networks on ISA Server, and then configure networkĪnd access rules that inspect and filter all network traffic among all
