Solved How do i DMZ

[Laith]

So i picked the decision of DMZing because some ports wouldn't open by port forwarding. The router is a brand made by the ISP called Compal or CPM. Any help on how i can DMZ. I went to the options and picked DMZ and put my computer IP but still no success. Any help guys?

I have done that along time ago with no success

 

[maxie]

Can you find out the Model Number of your Router ? ...

Laith, for what are you trying to open ports for? Which ports? DMZ'ing your PC isn't a very wise thing if you ask me

 

[Laith]

I know it isn't a wise thing but i've tried portforwarding a port and it wouldnt work so i decided to DMZ. My internet has enough protection to defend itself. The port is 7777(it is for a game)

 

[GokAy]

Terraria? How do you know port forwarding is not working? How are you testing it? Any firewalls on your PC? Is the game running when you try?

 

[Laith]

Heh, yup Terraria. It did work before at my old house but here at my new house port forwarding isn't working at all. My friends could join and portchecker.co says it was open on the old house. In the new house none of my friends could join and portchecker says it is closed. Also something worth to mention that one of my friends could join and i think he port fowarded 7777. Weird.

 

[GokAy]

A new ISP or still using the old one? Did you call ISP and ask whether they have the ports closed? Some ISPs charge extra for open port subscriptions. Also, are you getting a proper Internet IP on router WAN interface?

Possible to connect directly to modem or set router bit to bridge mode?

 

[Laith]

The old ISP with new router. The old router was a Netgear. Yup i do get an proper IP. I've connected directly to my modem. There's something weird. My Minecraft server has the port 25565 and works perfectly, portchecker.co says it is closed. My personal website works perfectly too with the port 80 portforwarded aswell as my TeamSpeak server works perfectly too. Portchecker.co says all ports are closed expect their working. Terraria is the only one who dosen't work.

Are the programs/games running while you are checking the ports? They will fail if nothing is there to respond on your computer. (Since you are forwarding port checker won't distinguish if router is allowing or not, computer will decide the outcome). So, make sure firewall rule to accept incoming is allowed too.

Just made a rule and checked with portchecker.co, all seems good.

Can you post a screenshot of the forwarding rule please?



Check router Firewall section too just in case. Try Low protection for example or even off (if possible) as a test.

 

[Laith]

I've never tested that, i'll try now.

 

[GokAy]

My rule:


So, make sure:
- The rule is correct (mine has both TCP/UDP).
- PC firewall has incoming rule allowed for TCP 7777 (maybe UDP too?)
- Game is running and server has started

 

[Laith]

OMG yes! It says that 7777 open! Lets wait a little till my friends connect. Thanks a bunch, Gokhan.

EDIT: I think the thing that made it working was my upgrade to Windows 10. Because i've tried that many times before (i think).

I am confused now

I fail to understand how Windows 10 changes anything on Windows 7 Try changing the router firewall back and see if it stops the forwarding? Are you running Win10 or Win7 at the moment?

Hopefully, it will work while actually connecting too.

 

[Laith]

Yup, i'm still waiting for my friend to join.
I'm running Win10. I'm confused as well but it works! I'll try to do that.

 

[Laith]

Yeyyyyyyyyy! Port forwarding works now aswell! Ｏ(≧▽≦)Ｏ

 

[Laith]

This thread is officially solved! Thanks Gokhan!
