Jeff Schertz  Amazingly enough these topics still comes up daily in technical forums, planning discussions with customers, and when troubleshooting improper deployments. Although most of this material is not new and can be found in various places this article is intended as summary reference for readers new to the elusive concepts of Edge and Reverse Proxy services. Overview. Firstly the most important concept to understand when dealing with externally publishing Lync services is exactly what the Edge Server is responsible for handling as well as what it is NOT designed to do. Throughout the documentation a Reverse Proxy Server will be referred to often and it still seems like this concept is often glanced over or not clearly understood. Edge Server. The Edge server is responsible for handling all communications and payloads in Lync Server which are made available to external and federated users with one exception anything related to Web Services. Note that this does not generically mean stuff over ports 8. TCP 4. 43 is used throughout Lync for a variety of different communications. More accurately it could be said that client communications to servers over HTTP and HTTPS are the types of traffic that are not handled by the Edge server. Everything else SIP, PSOM, ICE, etc are all provided by the Edge server.

Isa Server 2006 Serial Key' title='Isa Server 2006 Serial Key' />Reverse Proxy. The Reverse Proxyserver is an optional, external component that is not a Lync Server role and is not defined in the Lync Topology. The reason this component is considered optional is because without it deployed an external Lync client can still connect to Lync and most features will function IM, Presence, Calls, Desktop Sharing, etc as will federated communications. Only the features listed on this page will not be available to external clients, which although are important in a fully functional deployment they are not critical. Yet best practice is always to provide for these features by publishing the internal web services. A Reverse Proxy is also required to support any external Mobility client connectivity. Traditionally Microsofts Internet Security and Acceleration ISA 2. Server or Forefront Threat Management Gateway TMG 2. Internet the various web services running on internal Lync Front End and Director servers. But any third party solution, be it software or a hardware appliance, which has the capacity to publish the internal IIS HTTPHTTPS services can typically be used. A brief search online should reveal a handful of documents on how to provide access to internal web servers for various other products. Also simply configuring port forwarding from the Internet to the internal servers is possible, but not recommended as a true reverse proxy solution would have the ability to provide traffic inspection and added security on inbound connections directly from the Internet. Topologies. The questions asked most often are typically related to designing the topology e. Consistently deployments will attempt to use unsupported configurations like a single network interface or not enough unique network subnets, or 4 interfaces with one external interface on an internal subnet with another external interface connected to an unsupported firewall, and so on. For the best chance of a functional, supported, happy Lync Edge server the guidelines provided in the Assumptions section of the official Lync Edge Server Reference Architecture documentation should be followed as closely as possible. Granted there are production deployments out there working just fine which do not match some or all of these requirements, but those can often be the exception to the rule. Also receiving support for problematic deployments or future production failures can be difficult as although Microsoft will provide best effort support in these cases, the further from a supported scenario the longer the resolution time can be. For this article two different topologies will be used as examples and the the differences among them will be highlighted throughout the various sections. Simple Topology. The simplest, fully featured deployment would consistent of a single internal Standard Edition Front End server with a single consolidated Edge server and Reverse Proxy serverappliance located in a perimeter network. This topology contains a single SIP domain and uses the least amount of hostnames possible to still provides all client functionality. Complex Topology. Jumping right into the deep end this sample topology swaps out the Standard Edition server for two separate Enterprise Edition Front End Pools and introduces the Director role. Every role is comprised of multiple computer pools to provide fault tolerance to every available feature. Additional SIP domains are also included, as well as the concept of wildcard certificates. Best Practices. Always use two network interfaces on two separate subnets. The external interface should include the default gateway and the internal interface should not. Persistent static routes should be defined on the Edge server to address connectivity to internal subnets. As stated earlier the Edge server does not handle any web services requests. This means that without the optional Reverse Proxy then none of the features provided by web services will be available for external Lync clients and devices e. Lync Web App. Additionally the Lync mobile client for phones and tablets will also not function without a Reverse Proxy deployment as these clients are 1. IIS web site Mcx running on the Lync Front End servers. The Edge server does not handle any communication with the mobility clients themselves as they are not SIP clients, they only leverage HTTPHTTPS communications. The only role the Edge server plays in terms of Mobility is that it is used for establishing Push Notification communications via Federation services. Deep Ze Standard Edition 7 more. A Lync Director server is not a required server, even when an Edge server is deployed. It is an optional server which can be used to offload user authentication processing, create an additional layer of protection from external user connections, and provide a single location for internal client connections per SIP domain to be proxied through and redirected from. A single Reverse Proxy Web Listener can often be used for all published web services per internal pool. The official documentation often shows creating unique listeners for every different URL but this can be costly in terms of IP addresses. When using ISA or TMG it is possible to use the same Web Listener, IP address, ports, and certificate for multiple publishing rules by defining the specific URLs in the rule configuration. This holds true only when all published URLs are from the same internal server, so in a single Front End server deployment then a single listener can be used. But in a more complex deployment with multiple Front End server pools and Directors then a unique listener is required for each source server. For example the Complex Topology depicted below would require 3 separate listeners and external IP addresses, one for each of the three pools the same certificate can be used across all listeners though. Certificates. Coming in a close second is the amount of clarifying questions surrounding certificate configuration for the external servers.
