Look at a tech support on the website of the company that makes that router. Really all you need to do is go into the port settings and change allow to port 6112. That's all I had to do but it took up all of the bandwidth so it got cut off after like 2 days when everyone's internet was slower

But that's all the help I can offer you without actually getting a look at the port settings and whatnot. Hope you can figure it out
