Here's how it worked for me:
1. L2Walker 10.4.8 english from

2. Edited the "hosts" file found for WinXP in: \WINDOWS\system32\drivers\etc& #092; with "220.76.12.2 L2authd.Lineage2.com"
3. Created Microsoft Loopback Device (Network Adapter) with IP 220.76.12.2 and SubMASK 255.255.255.0
4. Used a tunnel with TCPTunnel from port 2106 to 206.127.151.66 port 2106
5. Used WPE PRO with new posted replacements (maby the author will enlighten us more explaining what they modify and how they work in the near future) linked to the L2Walker app.
Main issue: Game Guard is detecting WPE PRO and exiting the game, so I used a friend's computer to install L2Walker, the loopback device, a tunnel to my computer from his 2106 port to my 2106 port, WPE PRO with necessary adjustments and a second tunnel from my 2106 to destination port 2106. Any idea of how to hide the WPE process(es) (Ii saw "wpe pro.exe" and "wpmon.exe" as for now) ?
The protocol used for USA servers has become 553 or so L2Walker uses now.
All the best to you.
