be sure to portforward both 7171 and 7172
and check firewall (This never works for me)'
Also if your running apache and MYsql be sure to portforward those if useing webbacc-maker.
run -> cmd -> ipconfig
Check your Ip-adress 192.168.0.1 something, you have another adress.
Then go portforward it in your Router. Username: admin and password is usualy = password (Or check your papers at home or the nearest support for your router)
POrtforward both tcp/ip (Any) And make sure you portforward 7171 and 7172.
There is other ports for Apache and Mysql but i dont remember then right now
Have fun - if this worked
