My Book Live can't remote access on internet

My book live have IP 10.243.66.1 subnet 255.255.255.0 in my room. But when I use on other place in university I get IP 10.66.243.x subnet 255.255.255.0 . When I remote with IP 10.66.243.250(Forwarding Virtual Servers on my router)  it can’t remote access it’s has show error message "

You don’t have permission to access /UI on this server." This problem have not on firmware 1.x. Can you modify firmwave newversion to support this function for me?
