Hi list, I use an OpenVPN based internet access service (like NordVPN, AirVPN etc).
The issue with these public VPN services, is the VPN servers are always congested. The most I’ll get is maybe 10Mbits through one server. Local connection is a few hundred mbps.. So I had the idea of running multiple openvpn tunnels to different servers, and load balancing outbound traffic across the tunnels. Sounds simple enough.. However every vpn tunnel uses the same subnet and nexthop gw. This of course won’t work with normal routing. So my question: How can I use rdomains or rtables with openvpn clients, so that each VPN is started in its own logical VRF? And is it then a case of just using PF to push the outbound packets into the various rdomains/rtables randomly (of course maintaining state)? LAN interface would be in the default rdomain/rtable.. My confusion is that an interface needs to be bound to the logical VRF, but the tunX interfaces are created dynamically by openvpn. So I am not sure how to configure this within hostname.tunX etc, or if I’m even approaching this correctly? Thanks, Andy.
