I have almost finished my server but for the moment it is in localhost and it is running on hamachi ... I have a very good computer I have tested with lots of friends but the only problem is that everyone must install hamachi. Do you have another software like hamachi so that my server stays in localhost but that players do not need to download any program other than the nostale client
with hamachi it is super simple but the players must download it also ... I seek the same thing but without that the players download program
Except if you are opening your own ports to the internet, you can't do that, Hamachi creates a software layer private network to link computers between each other, but it relies on real internet.
Just create a backup of your mssql database, a quick google search will help you. Btw, at least use SQL scripts instead of inserting your data by hand, you'll spare some time.
If you have public IP address without some sort of ISP NAT you may host your server without hamachi. Just unblock the ports on your router/switch and forward them to your computer. In case you are behind the NAT you may ask your ISP to provide you public IP address. Some ISPs allow that for free, others require additional fees but in some cases it is impossible.
