DMZ - how to check if it's set up correctly?

[mattek]

Hi there,

after setting up my DreamPi correctly, I tried to extend online with enabling DMZ for Dreamcast. Here's what I did:
-went to router configuration page, found DHCP table and set 192.168.1.40 for my DreamPi (everything works correctly with that)
-secondly, in DMZ option, chose "Static IP" and typed 192.168.1.98 - it's IP which is used when connecting to Quake 3 Arena


Are the above steps correct? I'm asking becasue I couldn't find any idea to check if Dreamcast has ports opened. I know that connecting to game may verify DMZ, but e.g. Worms require all the players to have it enabled, so if one person has something configured wrong, I won't be able to identify who made mistake.

Best regards!

Starlancer is a good check. Connect, start a game, then with a device on the same network go here https://pentest-tools.com/network-vulne ... nline-nmap

Select the list tab and input 47624
Check the don't ping host option
Start scan
It should show as open if DMZ is working

Where does it say open? In the raw data? I just see a bunch of true false on the page when checking

If Alien Front Online doesn't disconnect you if Planet Ring you see yourself in the user list upon logging in your DMZ is effective =}

Like mista said:

1. Try to create a game in AFO, if you don't get a synch issue your OK.
2. Create a account in Planet Ring, if you don't get table full in the mini games your OK

So, because I can't figure out DMZ option in my router, I decided to open ports for Dreamcast manually. It looks like this now:

Without port forwarded, after hosting Alien Front Online game, it informs me about comunication problems then disconnects. With port opened, I'm able to play without any problems.

It means I have correctly forwarded port for DreamPi?

EDIT:
I see Shuouma post. It looks like everything is working perfectly now. Thank you!
