  5. For most servers, the SSH default port is 22. It is also the default port on Sigma.
    Check that the
    port on your SSH server matches the port on Sigma.
  6. In Sigma, navigate to your connection’s page in the Admin Portal.
  7. Under Connection Credentials, switch on the SSH Tunnel.
    Set these parameters:
    Tunnel host
    This is your IP address.
