There are two methods of connecting the frontend to a kernel: MathLink
(new/current) and MathTalk (old).  As I understand it, the latter does
everything through the telnet connection (the same one that the kernel was
spawned in).  The former actually opens a new connection between the
kernel's host and the frontend's host and communicates with its own
protocol.

Getting to the point, the MathTalk protocol should work for you (it is an
option in the frontend's kernel configuration window).  The downside is
that I found MathTalk to be somewhat slower and less stable than MathLink.
