This is one of OpenVPN's hacks to route traffic through your tunnel while maintaining your default gateway. The 0.0.0.0/1 and 128.0.0.0/1 routes take precedence over the 0.0.0.0/0 route since they are more specific while still matching all addresses. Search for "def1" in the OpenVPN documentation for more detail

Sep 13, 2017 · We get a route-based VPN because we bind the st0.1 interface to the VPN-V1-1 VPN. Once the VPN is up, any packet entering st0.1 will be encapsulated and sent to the 2001:db8:1::1 endpoint. The last step is to configure BGP in the “private” routing instance to exchange routes with the remote site: Routes can be conveniently specified in the OpenVPN config file itself using the –route option: route 10.0.0.0 255.255.255.0 10.3.0.1. If the OpenVPN server in the main office is also the gateway for machines on the remote subnet, no special route is required on the main office side. When I try to connect to any of my OpenVPN servers, I can ping correctly through to the remote network, but any time I try to browse the net or anything else, it just times out. I have set net.ipv4.ip_forward=1. The route is correctly set to have default via (tunnelIP) dev tun2 proto static metric 50 as my default route
