    return false
    }
    }

the log only show

Heder Destinatnion = null

Heder Source = null

Answer 1

If your ISOSource implementation is actually a channel that extends BaseChannel (most channel implementations extend BaseChannel ), then you can cast your ISOSource to BaseChannel and get a reference to the underlying socket using BaseChannel.getSocket() .

If you are using QServer you can configure the allowed hosts using the allow property.

And of course, you can use a firewall.
