Sends a tiny bit of dummy traffic every N seconds, keeps a NAT router from just forgetting about your client's state. I imagine Algo doesn't include that line because the generated config is for Android phones but for a laptop or desktop behind NAT, you pretty much always want it. This is especially true for things like public WiFi where the routers can be particularly keen to forget you.

Edit: There's a blurb about it on the website as well that is a little less handwavey than what I typed:

Please submit an issue and I'll fix it! -AlgoVPN developer


What Algo does now seems technically correct (the best kind of correct!) since it essentially says WG is for Android. I've added the issue though, for when more desktop-y clients are officially supported.

Thanks!
