Use the Connectivity Test Page¶

Reemo provides its users with a connectivity test page. This page allows you to check each step required to use Reemo with the best possible network performance. The test is available here: https://reemo.io/test

When you are ready, click the Start the Test button in the middle of the page.

Note

For maximum accuracy, the test should be executed both from the local browser (user side) and from the remote computer.

Step 1: Signaling¶

A connection is established with our signaling servers over WebSocket on port 443. If the signaling servers are not accessible, this test will fail and you will need to open the firewall rules described in the error message.

Step 2: UDP¶

A WebRTC connection is started and a UDP candidate is required to continue. If your browser is unable to provide a UDP candidate, this test will fail and you must allow the UDP protocol on your computer.

Step 3: STUN¶

A WebRTC connection is started. This connection queries our TURN servers in order to retrieve WebRTC candidates. If your browser cannot reach the TURN servers, this test will fail and you must open the firewall rules described in the error message.

Step 4: Relay/UDP¶

Once the TURN servers are contacted, they send back Relay Candidates to your browser to establish a Relay/UDP connection. If the TURN servers do not send these candidates, please contact us at support@reemo.io.

Step 5: Firewall Settings¶

A WebRTC connection is started, querying a TURN server on port UDP 58200 to obtain a Reflexive Candidate. If your browser cannot contact the TURN server, this test will fail and you will need to open the firewall rules described in the error message.

Step 6: NAT Detection¶

A final WebRTC connection is started, querying our TURN servers in order to detect your NAT type. If you are behind a Symmetric NAT, this test will fail. You will still be able to use Reemo, but only through a Relay/UDP connection.

Note

For more information about Symmetric NAT, Direct/UDP, and Relay/UDP, please refer to our guide of the connectivity test or one of the guides for firewall configuration.

Result¶

Once your network is properly configured, you will get the following result:
