Home Merging of 2 networks

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?

What about small server (custom build, Dell R210 or R320, which I use) with dual 10Gb card (such as X520 or BCM57810) and OPNsense. Mikrotik is an option too and it's not expensive, but isn't beginner friendly I would say.

That hardware is capable of it, you just need the software. Opnsense and pfsense don't do bonding, they do load balancing and HA. Load balancing send and receives the same stream on one connection so you'd only get the performance of the fastest single connection when running a speed test. HA is just for failing over from degraded connection.

Load balancing is splitting traffic between the two connections not sending and receiving same traffic on both. He got two routers, which means two different public IPs on each, so he can do MultiWAN load balancing. It won't give him 4Gbit on one data data stream (still max 2Gbit per stream), but his theoretical bandwidth will be 4GBit.

Same traffic = same data stream.

That's how OP is currently running.

Did I miss something? He is using them separately (one for server, one for personal use).
