OpenVPN – Bandwidth throttling a limit to 2 Mbps for both upload/down

I played with networking and openvpn quite a lot (10+ years sysadmin in ISP) so how about this simple solution.

Create entry in dns that will have n ip addresses for one host (round-robin way)

In Openvpn client put remote name of host so round robin is achieved

On vpn server have two network cards, one is connected to public ip (round robin address 1), other one is connected to private class. Second server, different public address (round robin address 2), same private class.

Create tap0 interface that will bridge addresses to private interface, have single dhcp that will manage addressing to your clients.

This way i think you can achieve as much redundance you want..

if you are using windows as client side, i would suggest to netlimiter software as it's easy to use, the tc is hard to configure specially in case of download as you would use polycer shaper.

with netlimeter you can control upload and download speed easily, from the client side.
