Port opening AirPort express

I have 2 AirPort Express and I use them for my private network:
Optic Cable==>AirPort express==>(wireless)==>PC
I need to know if I can open some UDP and TCP ports and How can I do it.
Thanks

Hello Frix65. Welcome to the Apple Discussions!
To setup Port Mapping:
Assign a manual IP to the host device
System Preferences > Network > Show > AirPort > TCP/IP
o Configure IPv4: Manually
o IP Address: <choose an IP address outside of the AX's DHCP range: 10.0.1.2 - 10.0.1.200>
o Subnet Mask: 255.255.255.0
o Router: 10.0.1.1
o DNS Servers <your ISP DNS server IPs>
Setup Port Mapping on the AXS
To setup port mapping on an AirPort Express Base Station (AX), connect to the AX's wireless network, and then use the AirPort Admin Utility to change these settings:
Port Mapping tab
o Click "Add"
o Public Port: <enter the Port # which will be accessed from the Internet>
o Private Address: <enter the static IP address from above>
o Private Port: <either enter the same value as the Public port or the value you want your application/service to answer on>
o Click "Ok"
o Repeat the last series of steps for each port you wish to map.

  • How to find MAC address for WAN port for Airport Express 2nd Gen.

    The New Airport Express has a LAN and a WAN ethernet ports. How can I find the MAC address for the WAN ethernet port as my Service Provider needs it for provisioning....I can fid MAC address for Ethernet and for two wireless 2.4 & 5GHz but not for WAN ethernet port using Airport Utility 6.1

    Many thanks for the swift response. However, there is no WAN MAC address on the box or on the device anywhere. I even used magnifying glass to find one .
    The airport utility shows only three mac addresses. One for 2.4GHz, one for 5GHz and one fo the ethernet (LAN port) whereas there is another ethernet port in the device mentioned as WAN port and I am still not able to find the MAC address for the WAN ehternet port for Airport Express (2nd Generation).
    Will appreciate a response to make th device work wiht my service provider as providing them the WAN mac address is a must. Had there been an option for cloning mac address, the issue would have not been there.
    Many thanks again - in advance.

  • Opening Ports on Airport Express for GTA IV

    I am told that to play Grand Theft Auto 4 (GTA 4) properly, I need to "open ports" on my router and enable UPnP (Universal Plug-n-Play).
    The ports I am supposed to open are:
    UDP
    3478
    3479
    6672
    28900
    TCP
    80
    443

    8001
    8080
    27900
    On my Windows 2000 machine, using the AirPort Admin Utility, when I configure the AirPort, I get a window that has a "port mapping" tab.
    Is this how I open the ports listed above? If so, it asks for a private IP address, Public Port, and Private port. How do all these relate to the port numbers above?
    In the configure base station window, i can't find any mention of how to enable UPnP
    Thanks!!!!!
    PS, don't hate on me for having a PC, i'm just waiting until Apple comes out with a BluRay capable laptop...

    Yes.
    To setup Port Mapping:
    Assign a manual IP to the host device
    The "host" device is the computer that will be hosting GTA and needs to be accessed from the Internet. Under Windows 2000, you would use Network Settings to assign a static IP address to this computer. Note: Be sure to assign an IP address outside of the DHCP range provided by the AirPort Express Base Station (AX) default range of 10.0.1.2 - 10.0.1.200, like 10.0.1.201
    To setup port mapping on an AirPort Express Base Station (AX), connect to the AX's wireless network, and then use the AirPort Admin Utility to change these settings:
    Port Mapping tab
    o Click "Add"
    o Public Port: <enter the Port # which will be accessed from the Internet>

    In the configure base station window, i can't find any mention of how to enable UPnP
    Unfortunately, that's because the AirPorts do not support UPnP. Instead, the AirPorts have a similar feature known as "NAT Port Mapping Protocol." You enable/disable this function on the Ethernet Port Security tab under Base Station Option within the AirPort Admin Utility. Note: Although NPmP is similar, it is not the same as UPnP and may not offer the same features. If GTA requires UPnP, the AirPort's NPmP feature may not support it.

  • PC will not Recognize Wireless Open Airport Express Network

    I am trying to connect my computers to the Airport Express base station. Decided to upgrade the wireless internet router to n speed from g and the signal kept dropping. I've used an extreme and express at work set them up and have them running for both PC and Mac however, when i ran this express at home 2 MacBooks picked up the signal no problem however, the Dell PC did not. I disabled all firewalls on the PC, even made the network open with no encryption and still the PC did not recognize the device. It is not a range issue as i had the Dell 1 room away and even checked the selection for it to protect against device interference. The apple help told me to reboot and try everything i mentioned above. His final suggestion was to purchase a Mac, not really the solution i was looking for. Any help or further suggestions would be helpful thanks! I love Mac products and they just work so i am scratching my head over this one I am sure it is on the Dell side.

    Hi again,
    Yes you can use an All-in-One HP to do 'All' it's functions wirelessly... with an Ethernet Printer and Connection. (I believe HP calls them "Network Ready"). I am doing my HP 2500 series this way, and yes, it Scans too. It does depend on which printer port you use and how the printer responds. It's Ethernet Port works well, but the USB does not... tried both plugs with the Airport Extreme. Also, the Airport Express has both plug types, I'd use the Ethernet one.
    Another thing, I had to enable "AppleTalk" with this printer to get through the barrier and have it scan. AppleTalk uses the 'same' language as the printer (or visa-versa???), and I believe this is the way HP is using to have more of it's printers usable with us Mac owners.
    As the 6300 series is a small business printer, it should be Network Ready (and have an ethernet port on the printer) and be able to be done similar to my network ready 2500 series. But with two different series, I'm not sure how HP equipped yours... that is why it's nice to read up on all the stat's and work a rounds on their web-site.

  • Need Help with 5 Port Switch, Airport Express, and wired iMac

    I recently purchased an airport express to accomodate my laptop's wireless capabilities. However, the airport express has only one ethernet port, as does my parents' modem. Thus, I could either hook up the airport or my parent's iMac. I chose the airport, which resulted in a few weeks worth of fights. To alleviate the problem, I purchased a linksys 5 port group switch, after someone told me I could use that to hook up both at the same time. Initially, the iMac wouldn't work. It registered what I was told was an invalid IP address. Then a cable technician came by, reset the modem (unplugged the battery), and now the airport does not work; it flashes yellow and says that it cannot detect the ethernet signal. 
    The iMac is running OSX 10.3 and the laptop OSX 10.4.  I am not sure if the modem can only accomodate one IP address or if there is any way to share IP addresses. Do I need to change something with the DHCP on my laptop? Do I need to manually enter an IP? Any help would be greatly appreciated. I'm completely lost....and without wireless internet.

    Instead of a switch you need a wireless router, because your modem will only assign one public ip address to the switch and that ip address will be forwarded to any one computer at a given time...You should replace the switch with a wireless router and it should resolve your concern...

  • TA20713 Can I connect and IP Phone to the LAN port on Airport Express?

    I am having difficulty connecting my internet phone to the internet.  I have a Comcast Modem with only 1 ethernet port which is connected to the Airport Express.  We are using a secured wireless network and I do not have a way of entering a password or identifiying the network on the Internet Phone.  Will I be able to connect the phone to the LAN for Internet access or do I need something else?  Normally I would simply try this out, but we have an old Airport express as the primary wireless router and we'll need to re-work out in home network a bit to get the newer Airport closer to the phone.  I'd like to know if this is doable before we put all the effort in.  Thank you

    The Ethernet port on the "fios box" (I assume you are referring to a DVR/STB) is not active.  However it's easy to use a MoCA adapter to get a direct connection if you have a working coax outlet.  Simply search "MoCA adapter" in the "Ask the Community" search box for details.  Also look here:

  • Lan and Wan port on Airport express

    Hi guys I am wondering if you could help me out with my airport express.
    I recently bought an airport express and have it set up as the following:
    Router--->ethernet cable in to the Wan of Airport express--->ethernet from Airport Express Lan to computer
    This is so that I have hardwired internet to my gaming computer and wifi in my room for all my devices. The problem is, however, next year I will not be in a situation that allows me the same setup. I will be too far away to run an ethernet cable from the router to the airport express. So I have decided I shall use it to join the network wirelessly and relay internet through both the Wan and Lan port (think this is called bridge mode?). I was also intending on connecting an ethernet hub to one of the ports so that I can connect multiple devices, smart tv, macbook, ps3 etc. But having one of the ports exclusively to my gaming pc.
    My question is, with both Lan and Wan ports relaying internet to multiple devices, would I see a drop in performance, in particular in regard to my compter? Or is the airport express able to join both the 2.4GHz or 5GHz and relay each connection to a specific lan port?
    Unfortunately I am not in a position to test this yet, lacking a 5GHz connection in my halls, so I would appreciate if anyone could help shed some light.
    Thank you

    is the main router also an apple product? if so, then yes you can extend wirelessly, but if the main router is an apple product, why are you bothering to extend wirelessly at all when the main router's signals should be strong enough?
    if the main router is NOT an apple router, then you wil NOT be able to extend it wirelessly period.
    in my experience, there are very FEW places you NEED to extend a network wirelessly, and i always recommend against it since there is a big performance decrease.
    In the case of a wirelessly extended network, throughput may be reduced to less than 60 percent of that of a single device.

  • How much power can deliver the USB port on AirPort Express?

    I am developing an appliance that requieres access to a WiFi router and a power source (UL 60950-1 compliant) of less than one watt (100-200 mA @ 3.3V) to power my own WiFi device, and the AirPort Express can be the right device to solve both problems with minimun overhead. The problem is that I cannot find the specification of the current / power limits of its USB port.
    To check if it can provide the usual five unit loads, I tried to charge an iPhone 4, but it fails showing the message "Charging is not supported with this accessory", and an external 2.5" HD which requires 500 mA causes the following message to appear on AirPort Utility:
    USB Power
    A device connected to this AirPort base station's USB port requires more power than this AirPort base station can provide. Plug the device into a power supply if possible, or connect it to a powered USB hub.
    Any insight will be welcome.

    Never mind - I tried "rebooting". I hate it how that always works!

  • Can Slingbox solo be plugged into the Ethernet port on airport express to connect to network?

    Slim box requires a wired connection to your network unless you purchase their sling link to create a wireless connection through your home electrical outlets.  Can an airport express be used instead?  Would the sling box plug into the Ethernet port on the express or though the USB port.

    It may be possible as the 802.11n AirPort Express can be configured to enable its Ethernet port for wired clients in one of two methods: 1) The Express is extending another AirPort, or 2) The Express is configured as a wireless Ethernet bridge.

  • Can you connect VIA USB port on Airport Express?

    I have a Airport Express and have the ethernet port used already. Is is possible to use the USB port to hard wire a computer to the Express? I know it meant for a printer but dont need it for that use.

    Sorry, but no. The USB port on the AirPort Express is designed to only support USB printers.

  • Number of Ethernet Devices Supported on Ethernet/LAN port of Airport Express

    I am using an Airport Express to extend my wireless network (Apple Time Capsule Base) and using the ethernet/LAN port to connect a wired device (a DirecTV DECA) so that my DirecTV HD DVR box can connect to the internet thru my home network. Works great. I have Whole Home DVR installed and so the other DirecTV receivers in the house are connecting to one another over the the coax and using the (DECA - Ethernet over Coax) to talk to one another and they each recieve an IP address via DHCP from the Apple Time Capsule Base - obviously thru the brdige created by the AirPort Express. Recently added an additional DirecTV reciever and for some reason this one will not get an address? Is as if the Aiport Express has "maxed out" the number of ethernet devices it will connect or bridge on the LAN side? I have tried shutting everything down and bringing DirecTV recievers on in different orders and it is alwasy the last one (the 5th one) that fails to get an address. Anyone have any knowledge if there is indeed a limit of the number of ethernet devices that are supported on the Ethernet/LAN port of the Airport Express? Thanks for any insight.

    in theory, yes, but you work network admin may have locked the network preventing this from working

  • Add additional ethernet ports with airport express

    Is there a way to add an additional ethernet port to an airport express via a router or some other option? I have a need for two devices using ethernet next to the airport express.
    Thanks,

    If you want the AX to connect wirelessly to a network and then connect Ethernet clients to the AX's Ethernet port, read Tesserax's post above. This requires WDS.
    If you want to connect the AX to an Internet source and also have Ethernet clients you want to connect to that Internet source, read my post above. This is not possible using only the AX. You need a router with 2 or more Ethernet ports unfortunatley the AX only has one.
