WAN prioritization on multi WAN router - TP Link R470T+

[superczar]

My config is as follows:

ISP

• 1 - DSL WAN (WAN 1) with very high data cap (as good as unlimited)
• 2 - 3G (WAN 2) with small data cap (10GB)
• 3 - 4G (WAN 3) with small data cap (10GB)

Router 1 - TP Link 470 T+ load balancing router - Used only for load balancing

Router 2 - Netgear R7000 connected router 1 serving all devices on the home LAN

What I would like to do is have router 1 route all the traffic through WAN 1 at all times except if

• WAN 1 goes down
• WAN1 is swamped and WAN 2/3 can take over the spillover load

I tried going through the entire 120 page TP Link manual to try figure out a solution but the manual is not of much help.
Any pointers on how this can be achieved (if at all)

The 470 should be able to handle a simple fail-over setup via the admin interface at: Advanced > Load Balance > Link Backup. That said, it's fairly limited in regards to weighted-balance and spill-over controls. The best you're going to get is combining "Bandwidth Based Balance Routing" (via Advanced > Load Balance > Configuration) with some traffic control policies to throttle client and/or aggregate bandwidth when thresholds are reach via Advanced > Traffic Control.

If much more than that is required feature-wise and the budget allows, you're probably best replacing the 470 with a beefier multi-wan router/firewall. If you want point-and-click simplicity, Peplink all day long -- namely the Balance 30 or Balance One Core in your case. Or a CradlePoint model. If your skilled enough, you could pursue Mikrotik, UBNT EdgeMax, pFsense, another router distro, or even a multi-wan UTM device. Any one of those should allow for better control, more reliability and better support if it's a Peplink, or CradlePoint/UTM with an active support license. Could be worth it if the need is great enough.

I would suggest using the netgear R7000 with vortex port of RMerlin firmware for your load balancing as through the ability of being able to set rules for firewall and other things it makes it configurable just like with mikrotik so perhaps a more complex approach may work if you cant get what you want from simple check and list boxes interface,
