I have an OpenVPN server at home network. When I'm in company, I can access my VPN server to login MSN or any other instant message which is blocked by company. Now I have configured OpenVPN client on my mobile phone(Samsung note1). But it couldn't access the internet after connected to VPS. I don't know why! It couldn't be a simple DNS problem because even accessing the router by IP address is not workable. One strange phenomenon is: There is a PLC in my home network. After connected to VPS, the mobile can access a it by IP address. The protocol of PLC is Modbus-TCP/IP. I feel very strange. So any one can help me solve this problem? Thanks!
