Lost my router and need help setting up my node

Many months ago I was able to get my router to work somehow through trial and error and a lot of guesses! 

But this weekend my old router broke.  I bought another one.  I remembered that I was suppose to forward to port 7890 and I thought I set the router up to do that, but my node is in the red on Nembex. 

If somebody could get me a very brief suggestion of the steps, I would be very happy and will try to get my node going.
