He is connecting to 217 then disconnecting and connecting to localhost......
And there is Fable Server IP 127.0.0.1 PORT 6121 ??????

not a bug, the server tells you to connect to 127.0.0.1. their client most likely has a proxy in it to direct you to the right IP.
or they just fucked up

it's an antibot ? how to fix it, to not redirect me....

figure out with a sniffer what the REAL ip is that your clients packets are eventually supposed to goto.

custom antibot
this is a won't fix
