Lineage 2 uses multiple ports across game, login, and auth services. TCP-Shield proxies all of them under one configuration with full multi-port support.
TCP SYN Flood Mitigation
Block entire countries from connecting with one click. Eliminate attack traffic from regions with no legitimate players on your L2 server.
Real Player IP Passthrough
Every connecting IP is scored in real-time. Known proxies, VPNs, Tor exits, and botnet members are blocked before they can disrupt your server.
Region-Based Blocking
TCP-Shield works as a transparent TCP proxy. Your L2 server software and all client packs continue working without any patches or changes.
