why does the routing rule 0.0.0.0/1 along with 128.0.0.0/1 cover all IPV4 internet addresses

when I encountered these two routing entries defined by OpenVPN, I was puzzled as to its exact meaning. I understand that they are placed there to override the default entry 0.0.0.0/0 because they are more specific. the more explicit a routing entry is the higher its priority. I also know that whether a destination IP address matches a routing entry is determined by the result of its bitwise AND operation with the subnet mask specified in the routing entry. If the result is equal with the network address, the entry will take care of its routing for it.

Unable to access network in Openvpn Server after establishing a successful VPN connection to it

Here in China, we are not getting public IPV4 addresses from internet providers any more since they are running out of them. So I will need a workaround to access home network from outside, and it occurred to me that an Openvpn client connecting to a forward server might help solve the problem.After much tinkering with various options, I connected successfully to the Openvpn server in my office, which has an assigned internet-facing IP address. But I cannot ping any devices connecting to my office's router, not to mention streaming video or downloading files.

Download BBC SOUND PROGRAMS

Radio audience has become a fringe group in the age of video content, and BBC is the only media company who haven't abandoned this old-timer group yet. Though you can listen to a good array of sound programs without downloading,  some would like to download their favourite radio shows and save them for listening at our convenience. Also, people living in countries like China are unable to visit the BBC site thanks to China's sky-high great firewall. So I set up a simple website specially for downloading BBC radio shows, which makes downloading them a hassle-free process.
