I can't find any info about a D-Link DI 6144 (614+ yes...is that 6144 a typo?). If the router supports UPnP, enable it within the router & choose the UPnP option within LW's tools > options > advanced > firewall config. Apply > ok to save.

If that's no help, have a look through your router's manual for info about how to set up port forwarding.
Here's a link to instructions for the DI-614...log into your router & see if the pages look the same as in these instructions. You might be able to use them for your router.

Note that you have to set up a static IP
LW's listening port & the port forwarded must be the same number.
