hi i followed Anacondaqq
this link and made an offline server but then my brother which is no staying with me decided that he wanted to play with me so i followed guide from
https://github.com/rathena/rathena/wiki/Install-on-Windows
port forwarded 6900
gave my brother a grf file with changed clientinfo.xml
but it doesnt seem to be working this is all i get
just kept saying connection closed but when i tried to connect from a lan computer everything works
