Apply Cake to a destination IP (corporate VPN server)

[SirAdelaide]

I've got OpenWRT nicely set up on a Pi5 with 1000/50 internet. Cake is doing well on the 50 upload, I disabled it for download as it wasn't really needed.
My corporate VPN is a crappy 20/20, split tunnel so I can still use the rest of my connection for accessing the rest of the Web. I often get lag when copying files and using RDP and browsing the network due to 20/20 being ridiculously slow.
Can I apply Cake to the VPN server IP? So far I've only seen how to apply it to an interface.

you haven't, openwrt doesn't support the Pi5 yet.
you're using some kind of home brew.

you could set up qos, capping the non-VPN traffic.

I compiled htop with libsensors support yet the option to display the CPU temp is not available... sensors does work though as you pointed out... why does htop not? EDIT: something wasn't selected. Rebuilding my .config gave htop with the functionality I expected. [yo]

The problem is not the non-VPN traffic, but trying to do multiple things through the VPN all at once.

I can't see how Cake on the router would help balance the VPN file transfer and other streams when the traffic is encrypted end to end.

At most, it could help with buffer bloat across the whole VPN connection, limiting transfers to and from the one IP to 20/20. So that's what I'm asking about: if you know a server is slow, can we use Cake to manage connection speed to that specific server to reduce latency.
