bolehroute lets you go around having to set up your modem to open ports etc, and also avoid any routing limits in your modem if theres any, like if your modem crashes after opening and closing a certain number of connections
bolehroute also allows you to have the same 'internet connection' , no matter what your actual internet connection is, as long as there is no usage or bandwidth limit and no problems with using udp port 1194... this mainly applies to people with laptops, so you could go to a friends house or use a wifi hotspot ... you could use a faster connection than what you have in your home, or not even have your own internet connection at all
