If you're doing a single network card setup, it's probably trying to connect
to your router rather than the LTSP server. You'll need to add IPAPPEND=3 to 
/opt/ltsp/i386/etc/ltsp/update-kernels.conf, then run:

  sudo ltsp-chroot /usr/share/ltsp/update-kernel
  sudo ltsp-update-kernels

This should add ipappend lines to
/var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default, which should tell pxelinux
to pass boot arguments to avoid making a second DHCP request, which could be
directly from your router, and not contain the needed LTSP information.

If your LTSP thin client environment is amd64, change i386 to amd64 above.
