first start apache and go to

or

and see if that works
if that works then we can move on
get your external ip
and put it in the files ( or put 0.0.0.0 to get all ip's)
then for the firewall
make yourself easy and put this range on it (tcp - udp ) (note , firewall is basicly disabled then )
then you are sure that all ports are open , or start fine tuning it by checking what ports are realy in use and what ports not (check files)
but first things first , check your firewall on your pc , and test out that localhost is working
if localhost is refusing , then you need to figure out what is blocking
if localhost is working then proceed with the above things then we can start trying out the second part
go to

(that ip you blacked out) and see if that works
if it does works then you are live
if it refuse to work , then still something is blocking
check if your router forwards to your ip (forgot that small part , but a router need to know where to forward the external ip to )
so forward the external ip to your internal ip (192.168.1.254 )
strange part i see is your ip , why is it ended on the broadcast ?? ( 254 is last ip and mostly used as broadcast adress) instead of 192.168.1.3 or so ??
hopely this helps you
