So, the central node has 3 IP address, depending of what is the

Ok, expressive argument. Hostnames are for humans, and namservers

I think the double connection interfers in a dirty effect: I used the
serial connection in order to mantain the telnet, then I pinged using
the eth cable. The bytes coming on the serial are the telnet stuff.
In other words: the "ping" was on eth, and the "pong" was in serial.
