I have Cisco EPC3925 ( Its main thing I think its router - right ? )

Yes, the Cisco EPC3925 is a combination modem and wireless router or gateway device. This is the device that you would need to configure for port forwarding/mapping.

Then I have connected Airport Express to it with ethernet cable ( It's working as DHCP and NAT I have double nat issue in my airport program I don't know what is this )

A "Double NAT" condition is when you have two or more routers in series where they all have NAT enabled. NAT is a service that is intended to allow you to share one Public IP address with multiple Private network clients. This is what allows you to have more than one computer on your local network have the ability to share an Internet access.

Since you have your AirPort Express connected to the Cisco by Ethernet AND the Express is configured to have NAT enabled is why you are getting a Double NAT warning.

Normally you would want all downstream routers to be reconfigured as bridges (NAT & DHCP disabled).

also Airport Express is set to create a Wi-Fi network, then I have connected Airport Extreme with Wi-fi and set to exceed wi-fi network and can't change anything in it , can't open ports etc. etc.

You will need to reconfigure the Express as a bridge. The fact that you have configured the Extreme to extend its wireless range is fine.

Also I've been looking in Airport Express ( the 1st device ) and I saw that there I can open ports , but I opened them and nothing happend ... ports are still closed

You do not want to open ports on the Express. Again, if you reconfigure it as a bridge you won't need to as all of its ports will be opened.

Ok I understand what u said, so I set my airport Express 1st device in bridge mode - if I do that I can surf internet without problems etc. Then when I set it to bridge mode my computer gets adress 192.168.1.X ( My computer gets 13 and I've set it to be static ) so my computer is 192.168.1.13 then -> I open ports for example 2700-27015 ( for steam ) in my router cisco website witch is 192.168.1.1 and in ip adress label I put my computer adress 192.168.1.13 after I do this I reset the router and turn it back on after all this everything should work fine and my ports should be open right?? Well..I've tried it.. after this I can surf internet without problems of course but my ports are still closed ... 😟 Im checking them on http://www.canyouseeme.org/ and it says they are closed 😟 I've tried with pultiple ports such as 80 .. and it just won't work 😟 I don't know why..

Also someone told me to use DMZ on and in ip adress put WAN ip of my airport express ( if its NOT set in bridge mode ) and open ports for my airport ( also I tried to open for my computer too ) - It doesn't work 😟

Please friend tell me you can help me .. 😟

If you have properly set up port forwarding on your Cisco router then the ports should be open. However, it may be possible that your ISP is blocking certain ports.

Also, you actually need to be remote to verify that your ports are opened or not. Using a service like CanYouSeeMe is not always accurate.

The DMZ option would be appropriate if you had the computer connected directly to the Cisco router.

But my ISP can't block all ports right? Even something like 80 port. Also I have opened ports in the past for utorrent for example it was working !

How can I check that without using some kind of site?? Im a member on some site that tells u if you have ports opened or not and the site also says they are not opened .. 😟

Ok I will disable the DMZ option.

Do u have any sugestions what I can do ?? Please ... I can post my screenshots of airport program and how it all looks if it can help..

Another program that I would recommend to test your Cisco router's public ports is from Gibson Research, called ShieldsUP!. Give this a try.

FWIW, I just tested mine and all my ports were closed. However, this is what I expected as I have my router set to "stealth" mode.

So all i can do is what u mentioned above ? set to bridge mode and open ports for my computer yes? 😟 and if this doesnt work ?

ok thank you very much for respones !

On cisco site in DHCP Client Tables only my AIRPORT EXPRESS AND EXTREME SHOWS UP my computer and any OTHER device in my house DOESN'T show there when i have airport in bridge mode what is going on how can I set this properly ????????

a1354 and the other no is not saying cant find the number anywhere on the device

What are the model numbers of your Express and Extreme? They would be something like: A1392 & A1408.
