Introduction and Background
The local ISPs in my company's neighbourhood only offer 125Mbps maximum upload per WAN connection because fibre has not yet been implmented. We have more than 1TiB of essential data to push to an off site location- preferably within a one day period. Our off-site location has approximately 300Mbps download speed.
We have two WAN connections, one for WiFi, one for the server network, each at 125Mbps upload. My thought is, what if the traffic was split across two interfaces, both connected to a separate LAN, connected to a separate WAN.
How can I utilize the upload speeds of these two networks most effectively? My ideas so far:
- Purchase a second static IP on each modem and assign each interface's MAC address a public IP, then setup some sort of round-robin or load distributed routing (suggestions welcome).
- Follow a similar trend as above but utilize a VPN and a second piece of routing hardware on the other end.
- Pay for an SD-WAN aggregator service: https://itel.com/sd-wan/
- Find a way to make this happen with two network interfaces on the main backup server.
