I downloaded L2Walker, TPCTunnel and hosts from this guide/tutorial.
I want to bot on L2Amerika server.

Host is replaced on etc folder by yours.
Tcptunnel is like this:
"tcptunnel --local-port=2106 --remote-host=208.68.168.218 --remote-port=2106 --stay-alive"
By the way, the server's ip on system was l2amerika.no-ip.org but I got 208.68.168.218 with netstat -n.
L2Walker is as it was, used your system for epilogue with 152 protocol and moved all my .dat files in there, I copied the files from L2Walker "Data folder" and pasted to the system's gameguard folder.
the Loopback adapter is 100% correct with IP 192.168.1.12 and mask 255.255.255.0
and I get verify fail, believe me I'm trying for over 4 hours to find a solution around this, changed host files, edited ips etc just to see If there's a chance to fix it, at last it got on my nerves and quited trying by restoring to your guide's settings but still same ****...
