A router with X? Why?
The X server automatically chooses its port by adding the display number
to 6000. But as the ports are 16-bits coded, port 65536 equals 0, so
displays 59536 to 65535 generate listening sockets on ports 0 to 5999.
Check the man page for "Xserver" - it'll be in there. TCP/IP connections 
are only needed when the X server needs to be able to allow remote
connections to run programs on the X server. Programs running on the
local machine can use UNIX sockets to do the communication instead. When
your $DISPLAY is set to ":0" you're using UNIX sockets, not TCP/IP.

RTFM. startx -- -nolisten tcp
