hi i am using virtual box with bridged network..i can ssh to the guess machine and ftp from the guest machine to the host but not the other way around. i am using ubuntu on both of the machines. i can even access Internet and ping the host and the host can ping the guess. i checked the ports. both port 21 and 22 are open.can anyone help me on that please? when i am trying to use the host only and the brdged adapter together, i need internet and two access btwn the host and guest. it is not working any idea why?
