  2. Reboot the server.
  3. Run command sudo iptables -t nat -S to verify the POSTROUTING's have cleared.
  4. Verify the AP's are now connecting.
  5. Delete the current sgwu by using the controller UI.
  6. Re-deploy sgwu by using the controller UI.

Additional information

If older versions of Smart Edge SW and Quortus SW are being used, then there may be some routing issues for the LTE application. This causes the AP's to fail connecting to the EPC which then prevents LTE operation.
