One of our clients has Big Leaf as a service.
What Big Leaf does is provide a box that sits Infront of our network. Any working ISP connection is jacked in to The Big Leaf box... And one feed comes out to my router.
The Big Leaf box provides One Static Public IP to my router. This IP does not change no matter what or how many ISPs are connected.
So I am guessing the box is using something like MPTCP to send traffic to a VPS somewhere, then onto the internet.
Rip 1 or 2 of the 3 ISPs out of the box, and a zoom call still doesn't drop.
My only problem with the service is it's way too expensive for me to use more often. I have dozens of home users who would Kill for this service. Right up until I show them the price sheet.
So I set out to build my "poor man's version".
Using a small forum computer I tried to build OpenMPTCP. Gave up on that due to various issues I couldn't figure out and the lack of support.
I loaded speedify onto the computer and after messing with bypasses and a finding the "right server"...
I lost my public IP as I am behind carrier grade NAT with their service. But I have pulled the plug on my primary ISP with a wifi call going... And it didn't drop.
They offer a "private server option"... Where you get your own Public IP address from a server they set up for you. Since this server is "yours"... You don't have to share bandwidth, can do port forwarding, and shouldn't have to worry about getting your IP blocked as services see it as a VPN.
That server has a bandwidth limit of 3TB per month. Which is suspiciously close to the light sail plan... At 10 bucks a month. But I digress.
Unfortunately... The server IP they gave me... Mapped to Canada, and broke all sorts of IP Geolocated services. Making me shut off the dedicated server and go back to the NAT'd IP. Which actually saved me 90 bucks a month.
The closest server to me maps as Canada... Breaking things again. The next public server has been blacklisted as a VPN. By several services. Then I somehow found another server, that is close enough and not black listed, YET.
So if you made it this far... What are other using for this sort of application?
I really wish this was something I could handle at the Tik level. Having a computer running Ubuntu then a 3rd party software, INFRONT OF MY ROUTER, seems like a service problem waiting to happen.
