maybe you miss some step, like config.
login\config\loginserver.properties
# ================================================================
# General login server setting !!! REQUIRED to configure to everyone !!!
# ================================================================
# Bind ip of the loginserver, use 0.0.0.0 to bind on all available IPs
LoginServerHostname=Lan IP
LoginServerPort=2106
GMMinLevel=100
# The port, ip on which login will listen for GameServers
LoginHostname=Lan Ip
LoginPort=9014
gameserver\config\server.properties
# This is the server configuration file. Here you can set up the connection for your server.
# Usually you have to change the ExternalHostname option to
# - 127.0.0.1 (if you want to play alone / testing purpose)
# - LAN IP* (if you want to play from another computer in the network)
# - WAN IP** (if you want to play with friends over internet)
# - Questions? => http://l2jfree.com
#
# * = If you want to get your LAN IP, simply choose "Start" => "Run..." then type "cmd" => "ipconfig"
# **= If you want to get you WAN IP, visit http://www.whatismyip.com

GameserverHostname= Lan Ip
GameserverPort=7777
# This is transmitted to the clients connecting from an external network, so it has to be a public IP or resolvable hostname
ExternalHostname= Wan Ip
# This is transmitted to the client from the same network, so it has to be a local IP or resolvable hostname
InternalHostname=Lan Ip
# Define internal networks (10.0.0.0/8,192.168.0.0/16 is default internal networks)
InternalNetworks=
# Define optional networks and router IPs
# IP (200.100.200.100) or fully qualified domain name
# (google.com) that resolves to an IP (use ping to determine if a domain resolves).
# Format: ip,net/mask;ip,net/mask,net/mask
# (mask 192.168.0.0/16 or 192.168.0.0/255.255.0.0 would be 192.168.*.*)
# Note: keep InternalNetworks and OptionalNetworks blank for compatibility with older login server
OptionalNetworks=
# The Loginserver host and port
LoginPort=9014
LoginHost= Lan Ip
If you have router enable Virtual Server and add ports 7777 2106 and 9014 and enter your Lan IP
