† You must change the administration port because WebRTC clients use 443. If the WebRTC browser tries to access
port 80, the Expressway-E redirects the connection to 443.
* Options for alternative management ports are shown on the web interface. You can use the CLI to change it to a
different port, eg. 7443, so that you can lock it down. We strongly advise against opening an external management
port on the public IP address. If the browser tries to access port 80, the Expressway-E redirects the connection to
your chosen port.
‡ You must configure your external firewall to allow NAT reflection for the Expressway-E public IP address. (Firewalls
typically mistrust packets that have the same source and destination IP address)
