Hi everyone have a big problem to solve,
so i have server(spare laptop runing ubuntu server 10.04) running on my local lan which ip is 192.168.1.9(an no-ip address is lmasss.hopto.org) where i uploaded tank.html but if i accsess my page using lmasss.hopo.org and try to move forward in responce from tank window i get error that my page 192.168.1.14(wifly all code similar to ethernet shield) is not accsesable.question is somhow to do so it still will send data from lmasss.hopo.org to 192.168.1.14 so i can control tank from outside of my lan?
