Device is not able to communicate with other devices (v1.10.x-v2.0.x)

Help if you have a device that can't communicate with other devices in your Airwall secure network.

If a device in your overlay is having trouble connecting to other devices, follow the instructions below to troubleshoot the issue.

  1. Ensure that the devices that must communicate with each other have trust to each other in at least one overlay.
  2. Ensure that the devices have a route to each other through their respective Airwall Gateways. For example, the Airwall Gateways are connected to the same underlay network.
  3. Ensure that the affected Airwall Gateways can establish tunnels:
    1. Open the Airwall Gateways for the devices, and go to Diagnostics.
    2. Check Build new tunnels if none exist, and run the Secure Tunnels test.
    3. If the Airwall Gateway does not show up, check your Protected Network policy.
    4. If the Airwall Gateway fails the test, check to ensure that at least one has UDP port 10500 open and accessible from the Airwall Gateway you are testing from. Or, implement an Airwall Relay as needed.
  4. Ensure that the Conductor is accessible on the TCP port 8096 and that nothing is blocking/filtering the connection.

Disable SHA-256

If the above steps do not resolve your issue, follow these steps:
  1. In the Conductor, go to Settings.
  2. In the Advanced section, select Edit Settings.
  3. For ESP transform , select SHA-1.
  4. Select Save.
