Problem 1.   I am trying to configure my Load Balancer for 20 Computer Gaming Cafe Setup.

                             I have 2 Internet Connections both are PPPoE I want one as Primary and one as Backup Link. After Configuring everything when i see in Status my WAN 2 always shows Disconnected. (Attaching Image Files for better understanding.) When I click Connect in WAN2 Option it gets connected and in Status both are shown as Link up (Connected). After some time, WAN 2 always gets disconnected. As a Gaming Cafe I do not want to miss a single Minute of internet connectivity.

                                  Is it suppose to be this way always??

Problem 2.    Today after completing Configuration of Load Balancer Few of my computer had unidentified network issue.

                               I had to restart everything Manually which solved the problem. Later I did some changes and Upgraded the Firmware to the latest Version.
                               Attached are the Screenshots of my configuration if I have missed anything please tell me.
