After weeks of hard work RnD not forgetting guide from MikroTik Community Members!
@@@ Many special thanks to "Alex K. Anwar" of
http://www.neosky.id for professional troubleshooting guide and I manage to solved my SOHO MikroTik RB750Gr3 Router to do Dual WAN Failover to hAPac2 Wireless Router?
Here is the secrets -> Solutions synopsis: The problem is resolved when I use reserved DHCP IP MAC assignment and I added in DHCP client ether4. Added ether4 to WAN Interface List and remove ether 4 from LAN Bridge list. Changed DHCP client ether4 Distance to 3. Cause LTE1 uses Distance 2 by default when Mobile USB Adaptor is plug in to the MikroTik Router USB port when I need a WAN3 Failover later. Best part is no complex script needed!
WAN1 is on PPPoE-out1 bridge via fiber optic cable Modem.
and
WAN2 is on Ether4 via Wireless CPE Router.
Does this Route Table make sense?
if WAN1 suffers outage to Internet
then WAN2 take over link
else WAN1 is back online
then switch back to WAN1
and drop WAN2 link
end if.
WAN1 0.0.0.0/0 Distance 1 (PPPoE_out1) [Fiber cable link]
WAN2 0.0.0.0/0 Distance 3 (Ether4) [Wireless CPE link]
*** WAN3 0.0.0.0/0 Distance 2 (Lte1) [Reserved for future backup]
192.168.88.0 Distance 0 (LAN bridge)
192.168.99.0 Distance 0 (WAN bridge)
WAN1 Gateway and IP X.X.X.X Distance 0 X.X.X.X [Dynamic]
WAN2 Gateway and IP 192.168.99.1 Distance 1 192.168.99.10 [Static]
*** Adding a WAN3 interface via lte1 USB Mobile Internet Data Plan @ TM UniFi Air Plan as future backup Internet connectivity later.
