While firewalls don't typically cause a problem for Legaler sometimes enterprise firewalls with restrictive policies need to be setup to allow Legaler to function normally.

Legaler requires only port 443 (TCP) to be opened to conduct a meeting

Optionally. we recommend opening the port Port 3478 (UDP) as it will give you a better experience. UDP is highly recommended over TCP for better quality audio and video. Port 3478 only accepts inbound traffic after an outbound request is sent. The connection is bidirectional but is always initiated from the corporate network/client so it is not possible for an external entity to send malicious traffic in the opposite direction. 

Finally to ensure the best possible experience, we recommend opening the port range 1025 - 65535 (UDP). This step is optional.

To recap the ports required for Legaler are:

  • Port 443 (TCP) - Required
  • Port 3478 (UDP) - Optional
  • Port Range 1025-65535 - Optional
