Error 403 when accessing outside of localhost

hi. localhost setup worked fine as in the readme,
when i try to use this from a computer in the network. i get 403 error.
i have ping, and telnet to 8080, 
what am i missing?

git clone http://git@10.242.53.5:80/myRepo.git
Cloning into 'myRepo'...
fatal: unable to access 'http://git@10.242.53.5:80/myRepo.git/': The requested URL returned error: 403

thanks.
