MiTeam Meetings
The following table lists the connections from MiTeam Meetings to the external destination unless specified. The rules used for establishing the connections assume a firewall that permits return traffic on these established connections. This is referred to as pin hole punching. If pin hole punching is not available or has been disabled on the firewall, then you must exercise your own due diligence in configuring and testing the connections with the ports listed.
- The port requirements for WebSockets are given here: Device communication protocols - AWS IoT Core.
- If you are using a proxy server, ensure that it proxies WebSockets and HTTPS.
- Check using Amazon Chime Readiness Checker whether your firewall rules require updating for AWS Chime support.
- For more information about VPN recommendations and network requirements, see Network Handling and Requirements.
- For AWS Chime rules, see Hosts, Ports and Protocols needed for Amazon Chime services - Amazon Chime Help Center. The CloudLink Platform IP address ranges in AWS will cover the AWS IP address ranges mentioned in the document link. For details, see the CloudLink Platform IP Ranges section in this document. In addition, the highlighted feature used is Amazon Chime Meetings, Chat, and Business Calling.
- ICMP must be enabled on the firewall.
