Plan and optimize the Wi-Fi bands and access point placement. Consider these factors: Implement QoS or Wi-Fi Multimedia (WMM) to ensure that media traffic is getting prioritized appropriately over your Wi-Fi networks. Planning for, or optimizing, a Wi-Fi network to support Teams is an important consideration for a high-quality deployment. Optimize WiFi Similar to VPN, WiFi networks aren’t necessarily designed or configured to support real-time media. Connectivity to Teams might not be efficient due to hair-pinning traffic through a VPN device. VPNs also introduce an extra layer of encryption on top of media traffic that’s already encrypted. Some VPNs might also not support UDP (which is required for Teams). Other reasons why Microsoft recommends bypassing the VPN: VPNs are typically not designed or configured to support real-time media. To implement a split-tunnel VPN, work with your VPN vendor. Bypassing your VPN will have a positive impact on Teams quality, and it reduces load from the VPN devices and the organization’s network. Split tunneling means that traffic for Microsoft 365 or Office 365 doesn’t go through the VPN but instead goes directly to Microsoft 365 or Office 365. Configure split-tunnel VPN We recommend that you provide an alternate path for Teams traffic that bypasses the virtual private network (VPN), commonly known as split-tunnel VPN. Intrusion Detection and Prevention Guidance If your environment has an Intrusion Detection or Prevention System (IDS/IPS) deployed for an extra layer of security for outbound connections, be sure to allow all Microsoft 365 or Office 365 URLs. Identify locations that can use local or regional egress points to connect to the Microsoft network as efficiently as possible. Routing to Microsoft data centers Implement the most efficient routing to Microsoft data centers. Port exhaustion will contribute to internal users and devices being unable to connect to the Microsoft 365 or Office 365 service. Ensure that adequate public IP addresses are assigned to the NAT pools to prevent port exhaustion. When multiple users and devices access Microsoft 365 or Office 365 using Network Address Translation (NAT) or Port Address Translation (PAT), you need to ensure that the devices hidden behind each publicly routable IP address do not exceed the supported number. Validate NAT pool size Validate the network address translation (NAT) pool size required for user connectivity. Maintain session persistence Make sure your firewall doesn’t change the mapped Network Address Translation (NAT) addresses or ports for UDP. For an example scenario, see Using Network Planner – example scenario. When you provide your network details and Teams usage, the Network Planner calculates your network requirements for deploying Teams and cloud voice across your organization’s physical locations.

Advisor for Teams Advisor for Teams is part of the Teams admin center. For information about configuring firewall ports, go to Microsoft 365 and Office 365 URLs and IP ranges. Network optimization task Details External Name Resolution Be sure that all computers running the Teams client can resolve external DNS queries to discover the services provided by Microsoft 365 or Office 365 and that your firewalls are not preventing access. #REQUIREMENTS FOR SKYPE FOR BUSINESS BASIC HOW TO#
