* Use this combination only in a lab environment. The following table is a matrix of the supported combinations of internal and external edge interfaces.Įdge Pool (Internal Edge) and Edge pool (External Edge) Matrix The following table shows the support matrix between the Front End Server pool and the internal Edge Server pool.įront End Pool and Edge Pool (Internal Edge) Matrix Remote user networkįront End Pool and Edge Pool Configuration Peer-to-peer communications with remote users include instant messaging, audio/video, application sharing, and file transfer. The primary interface is the interface that communicates with the Skype for Business Server components.If media bypass is required, we recommend that the PSTN gateway is configured to IPv4. Skype for Business Server does not support media bypass for public switched telephone network (PSTN) calls if the traffic is through an IPv6 interface. Client endpoint 1Ĭonferencing includes audio/video, application sharing, and data collaboration applications like whiteboarding and file sharing. After both clients have successfully registered, the following combinations are supported. Peer-to-peer communications include audio, audio/video, application sharing, and file transfer. IPv6 only configuration is not supported in the production deployment. The following sections outline the compatibility among these three configurations for various Skype for Business Server features.Ĭlient or server configuration with IPv6 only is supported only for lab or validation purposes. This configuration is supported in Skype for Business Server because in most cases the transition from full-IPv4 to full-IPv6 will take several years. IPv6 only Conversely, a full IPv6 implementation will exclude communication with many existing devices.ĭual Stack Dual stack is a network where both IPv4 and IPv6 addresses are enabled. An IPv4-only configuration will help to ensure that your Skype for Business Server implementation can communicate with most existing devices. Ultimately, IPv6 will be fully supported worldwide, but at this time, many companies and devices that your enterprise might need to communicate with do not yet support IPv6, and may not for some time. IPv4 only IPv6 was created because the world is running out of IPv4 addresses. There are several issues to consider with each type of configuration: You can configure Skype for Business Server to support only IP version 4 (IPv4), only IP version 6 (IPv6), or a combination of both (known as a dual stack). You have three options when configuring IP addresses in Skype for Business Server. If you determine you will be using IPv6 addresses, refer to the Configure IP address types in Skype for Business article. Migration and coexistence considerations for IPv6 This topic includes the following sections: The change in formatting and functionality for devices that use IPv6 addresses requires several deployment and configuration considerations in your Skype for Business Server installation. This provides not only a new set of addresses, but also a much larger number of them.Ī typical IPv4 address looks something like this: 192.0.2.235, whereas an IPv6 address looks like this: 2001:0db8:85a3:0000:0000:8a2e:0370:7334. IPv6 addresses perform the same function as IPv4 addresses (with some additional features), but instead of using only 32-bits, IPv6 addresses use 128-bits. Because of this, many new devices are moving to using IPv6 addresses. Due to the increasing number of devices worldwide, the available IPv4 addresses have run out. IPv4 addresses are 32-bit addresses that allow a computer to communicate over the Internet. Skype for Business Server includes support for IP version 6 (IPv6) addresses, along with continued support of IP version 4 (IPv4) addresses. Summary: Implement IPv6 before you install Skype for Business Server.
