Ever since I bought Blockland I always wanted to host a server for the 2701HG-G Gateway, now I learned how. The following is how to Port Forward your 2701HG-G Gateway system.
Step 1: Click the start Button, and click Run.

Step 2:Once you click on Run a small menu will pop up (like below). Type in
cmd, then press enter. Something called
C:\WINDOWS\system32\cmd.exe should pop up.

Step 3:Then type in
ipconfig /all, then look for Default Gateway and type the number be side it in your Web Browser.

Step 4:Type in your Default Gateway in your web browsers address bar.

Step 5:Once your there click on Application Support.

Step 6:Click on
Enable Application Support.

Step 7: Click on
Add a new user-defined application.

Step 8: Now Type Blockland in the Application Name. Then in the the boxes with
Port (or range): to the left of them write 28000 in the box more on the left then 28030 on the box more to the right. Then click
ADD DEFINITION. After that click on Back. I think the picture makes more sense.

Final Step: Heres the Final step!
Find Blockland on the box on the left most of the page then click
ADD which is right to the right of the box. Once you've done that Click on Done, which is on the bottom left of the page.

I hope my tutorial helped you. Have fun hosting Blockland Severs!
