Select each feature that you want to enable for the Edge pool. By default, the Edge pool supports remote users in your organization who sign in to Microsoft Lync Server 2010 from outside the firewall by using a virtual private network (VPN). You also have the following Edge pool feature options:
- Use of a single fully qualified domain name (FQDN) and IP
address for all edge services, including the Access Edge service,
Web Conferencing Edge service, and A/V Edge service. If you do not
select the option to use a single FQDN and IP address, you will
need to specify a separate FQDN and IP address for each of these
three Edge services as part of the deployment process. For details
about the Edge services, see Components Required for
External User Access in the Planning documentation.
Note: If you select this option, you must specify a different port number for each of the Edge services (recommended default port settings: 444 for Access Edge service, 8057 for Web Conferencing Edge service, and 443 for A/V Edge service). Selecting this option can help prevent potential connectivity issues, and simplify the configuration because you can then enter one FQDN that is used for all three services.
- Support for federation. Select this option if you want to
support communication between internal users and users in trusted
domains outside your organization, including any users of a
supported public instant messaging (IM) provider. If you select
this option, you will need to configure support for the specific
federated domains and public IM connectivity service providers that
you want to support. For details about configuring support for
federation and other types of external user access, see Configuring Support for
External User Access in the Edge Server Deployment
Note: Only one Front End pool or Standard Edge Server in your organization may be published externally for federation. All access by federated users, including public IM users, go through the same Edge pool or single Edge Server. For instance, if your deployment includes an Edge pool or single Edge Server deployed in New York and one deployed in London and you enable federation support on the New York Edge pool or single Edge Server, signal traffic for federated users will go through the New York Edge pool or single Edge Server. This is true even for communications with London users, although a London internal user calling a London federated user uses the London pool or Edge Server for A/V traffic.
- NAT support. Network address translation (NAT) is not supported
when you are using hardware load balancing, so do not select the
NAT option if you are deploying an Edge Server pool with hardware
load balancing. For details about NAT support, see Network Address
Translation in the Planning documentation.
You can add support for external user access when you deploy your initial topology or afterward. For details about adding Edge Servers to an existing topology, see Defining Your Edge Topology in the Edge Server Deployment documentation.
