Dead Space 3 – How to Fix Co-Op Connection Issue

A method for fixing issues with co-op in Dead Space 3.


According to my observations, this problem mostly occurs with old or cheap routers, buying a new one (most likely) can solve the problem without changing the router settings, but if you don’t want to change your router, you can do the following:

Open a Command Prompt and enter the ipconfig command.

Find the adapter that has the line Connection-specific DNS suffix: Home. After that, copy your IPv4 address.

Go to the router’s homepage, such as for Tenda routers, and open its settings.

Find the DMZ Host option and paste the IPv4 address you copied.

Find NAT, then click the add button and write the following. Use your own IPv4 address for this:

  • Port start: 8080, port end: 8080 and ip.
  • TCP/UPD protocol (or just TCP).

Find NAT Port-forwarding (or something similar) and write the following:

  • Switch: Port start: 8080, port end: 8080.
  • Open: Port start: 8080, port end: 8080.
  • TCP/UPD protocol (or just TCP).

Find UnPnP and enable it.

This issue should be resolved at this point. I recommend that you disable the DMZ Host feature and remove the port forwarding columns after you finish the game for security reasons.

I love two things in life, games and sports. Although sports were my earliest interest, it was video games that got me completely addicted (in a good way). My first game was Crash Bandicoot (PS1) from the legendary studio Naughty Dog back in 1996. I turned my passion for gaming into a job back in 2019 when I transformed my geek blog (Re-actor) into the gaming website it is today.
