Lineage II requires that TCP ports 2106, 7777, 2009, and 80 are fully unrestricted and accessible inbound and out. If you are connecting to Lineage II while on a campus or business network, please consult your network's administrator to verify that these ports are available. If you are on a Local Area Network (LAN) or behind a router, please make sure that your network's hardware is properly configured.
