Motivation: IP_TRANSPARENT support is not complete, the option can currently only be set on EpollServerSocket. Setting the option on an EpollSocket is also requires so as to be able to bind a socket to a non-local address as described in ip(7) http://man7.org/linux/man-pages/man7/ip.7.html "TProxy redirection with the iptables TPROXY target also requires that this option be set on the redirected socket." Modifications: Added IP_TRANSPARENT socket option to EpollSocketChannelConfig Result: A redirecting socket can be created with a non-local IP address as required for TPROXY
