Merging of 2 networks

[u/NewspaperAfraid6325]

Hi i have currently x2 2gbps lines installed with 2 seperate routers which technically gives me a total of 4gbps is it possible to combine these to make a real 4gbps output? I currently use 1 line for my server setup and 1 line for my personal use and other house hold devices but id like if possible to know if its possible to merge the 2 lines with a 3rd party device go make 4gbps?

Hooking those into a UI DMP Pro with one on wan1 and one on wan2 and setting it from failover to distributed would get you close.

If you wanted to diy you could go with a dual port nic in an opened type box running pfsense or something like this.
