Infelizmente eu to enferrujado também, comecei a configurar um emulador recentemente depois de alguns anos.
Mas pra deixar claro quais linhas você precisa alterar.
Char-server
// Login Server IP
// The character server connects to the login server using this IP address.
// NOTE: This is useful when you are running behind a firewall or are on
// a machine with multiple interfaces.
login_ip: "127.0.0.1" (IP LAN)
// The character server listens on the interface with this IP address.
// NOTE: This allows you to run multiple servers on multiple interfaces
// while using the same ports for each server.
//bind_ip: "127.0.0.1"
// Login Server Port
login_port: 6900
// Character Server IP
// The IP address which clients will use to connect.
// Set this to what your server's public IP address is.
char_ip: "127.0.0.1" (IP Publico do Host)
Map-server
// Character Server IP
// The map server connects to the character server using this IP address.
// NOTE: This is useful when you are running behind a firewall or are on
// a machine with multiple interfaces.
char_ip: "127.0.0.1" (IP LAN)
// The map server listens on the interface with this IP address.
// NOTE: This allows you to run multiple servers on multiple interfaces
// while using the same ports for each server.
//bind_ip: "127.0.0.1"
// Character Server Port
char_port: 6121
// Map Server IP
// The IP address which clients will use to connect.
// Set this to what your server's public IP address is.
//map_ip: "127.0.0.1" (IP Publico do Host)
@emiedson que bom que conseguiu resolver.
