Where is my 'Port Mapping' tab

I'm trying to open a port on my computer and have followed the instructions I have found here and on the net. 'Go to airport utility/click manual setup/click Advanced/ choose 'Port Mapping'.
I have no 'Port Mapping' option under Advanced.. I have only 'Statistics', 'MobileMe' and 'IPv6'.
Can someone point out what I'm doing wrong? Thanks

In AirPort Utility in the "Internet" pane, do you see a button for "Configure Port Mappings..."?

  • Help! no port mapping tab in airport utility port forwarding.

    Hello I am trying to port forward my airport extreme router to host servers.  I watched every single tutorial on the internet but nothing works because I dont have a port mapping tab under advaced in airport utility. btw I am running bootcamp windows7.  Thanks in advance

    Where are you looking?
    The settings for Router Mode are under the Network tab.

  • New Airport Extreme (802.11n): :  Port Mapping... ***???

    There are two different programs I was formerly using, whereby (after following instructions) I was able to create a static IP address for every machine on my network, plus open ports 8000 and 9990-9998 respectively. But ever since upgrading to the new Airport Extreme (802.11n), it completely stopped working. To boot, I've upgraded to Leopard on one of two of the machines (the other is still using 10.3.9).
    I haven't been able to figure out for the life of me, how to configure it. It's no longer as obvious where and what information to put in. All guides that would remotely help are designed for the older Airport unit, which has completely different menus in the Airport Utility.
    Is there anyone out there who has experience with Dot-Tunes and/or Nicecast or similar port mapping, who has the patience to describe, in layman's terms, what steps to take to get this set up correctly again, starting with how to reassign static IPs for my machines. I will not ask a lot of questions and take up too much more of your time. I'm just frustrated after a whole day of trying to figure this out and fruitless Google and forum searches.
    Thank you so much.

    I'm not familiar with either Dot-Tunes or Nicecast, but the following would be the general port mapping procedure with the 802.11n AirPort Extreme Base Station (AEBSn) using the AirPort Utility. Note in this procedure you will not need to assign a static IP address for each of your host devices. Instead you will be taking advantage of the AEBSn's DHCP reservations feature.
    To setup port mapping on an AEBSn, either connect to the AEBSn's wireless network or temporarily connect directly, using an Ethernet cable, to one of the LAN port of the AEBSn, and then use the AirPort Utility, in Manual Setup, to make these settings:
    1. Reserve a DHCP-provided IP address for the host device.
    Internet > DHCP tab
    o On the DHCP tab, click the "+" (Add) button to enter DHCP Reservations.
    o Description: <enter the desired description of the host device>
    o Reserve address by: MAC Address
    o Click Continue.
    o MAC Address: <enter the MAC (what Apple calls Ethernet ID if you are using wired or AirPort ID if wireless) hardware address of the host computer>
    o IPv4 Address: <enter the desired IP address>
    o Click Done.
    2. Setup Port Mapping on the AEBSn.
    Advanced > Port Mapping tab
    o Click the "+" (Add) button
    o Service: <choose the appropriate service from the Service pop-up menu>
    o Public UDP Port(s): <enter the appropriate UDP port values>
    o Public TCP Port(s): <enter the appropriate TCP port values>
    o Private IP Address: <enter the IP address of the host server>
    o Private UDP Port(s): <enter the same as Public UDP Ports or your choice>
    o Private TCP Port(s): <enter the same as Public TCP Ports or your choice>

  • AEBS Gigabit 802.11n FW 7.2.1 - OS X 10.5.1 Port Mapping HELP!!!!

    Hi
    I have a AEBS with Gigabit Ethernet upgraded to Firmware 7.2.1. I am running OS X Leopard 10.5.1 and I am unable to successfully forward ports. Every time I query a port that I believe to have mapped successfully it appears closed using canyouseeme.org.
    I have followed numerous instructions, but they all seem to be instructions for Tiger, I'm wondering if a setting has been missed. I have successfully assigned a static IP address to my machine but still the port appears to be closed. I do run the Leopard firewall using specific applications option (the third one), but I have also tried it with the firewall off and it still hasn't changed anything, the ports are always closed.
    So now I'm pretty much stumped. Has any one actually managed to get a setup similar to mine working, with the ports being open? All advice appreciated.
    Thanks

  • Port Mapping...access home network remotely

    Hello,
    Has anyone successfully established port mapping through the AE (802.11n)?
    SSH access has worked for me but nothing else. Apple tech support was courteous but unable to solve problem.
    I'm trying to get port mapping (port forwarding on other routers) to work for AFP and FTP.
    Any help would be appreciated.

    Hi Greg,
    Thanks for your response. I will try it out.
    Yes, I did get her the new AE 802.11n.
    I am so impressed by it, I would go buy it for myself to add the print server capability, and dual band feature.
    To take advantage of N, I will either get a new Macbook Pro, or a new wireless card for my PB G4, preferrably the former.
    Cris
    Hi Cris,
    I have actually been successful now with AFP too.
    Does your sister have the new AE 802.11n? That's the
    one I have and here's what I did.
    1) Open AirPort Utility
    2) Select Airport Extreme
    3) Menu "Base Station", "Manual Setup"
    4) Select Advanced icon
    5) Select Port Mapping tab
    6) Click "+"
    7) Select a service "SSH" or "AFP" which ever you
    prefer.
    8) For ssh, private tcp port needs to be 22. Public
    IP address should be the IP address of your sisters
    imac on her local network. Private TCP port should be
    22.
    AFP is the same setup as ssh, except the Public tcp
    port should be any unused port number, for example
    5912. (You can get a list of used port numbers here:
    http://docs.info.apple.com/article.html?artnum=106439
    ) and the private tcp port needs to be 548.
    Helping your sister out will be much easier when OS
    10.5 becomes available later this spring and perhaps
    by the end of this month. Go to this link and click
    on the iChat icon. It will show you ichat's new
    capabilities. http://www.apple.com/macosx/leopard/

  • Default Host (DMZ) and Port Mapping together

    Hi all,
    I have the G5 set as a default host for all my web services through the Airport Extreme.
    In the Airport Extreme's Port Mapping tab, a user is not prevented from using the port mapping tab even when the Default host is set. I want to serve video through another port not on the G5.
    Does this mean I can set up port mapping for ports I do not want to go to the default host? (my G5 in this case)
    I asked this on the airport forum and never got an answer, maybe you G5 folks might know. (Or maybe there is a setting that will redirect from the G5.)
    Thanks in advance,
    Jamy

    I figured it out. I can't have a DMZ and separately port mapping on the Airport.

  • Can't "add" to port mapping

    I am using an airport Extreme base station, and I am trying to enable Port forwarding for use with a Slingbox. However, when I go to the port mapping tab of the Airport Admin Utility the "Add" button (right side of the window) is grayed out. Can anyone help me? Why is it gray and not active?

    The extreme is hooked up to a cable modem.
    Is it a modem only or is it a modem/router combination? If it is a modem only I don't know why your AEBS has the option to distribute IP addresses DISABLED. In that mode you only have one IP address to use so only one device at a time can connect to the Internet.
    ...I want to hook up the sling box, and I am not sure what I need to hook that into, the Express or (AEBS).
    You can ONLY connect it to the AirPort Express (AX) if you configure the AEBS and AX to connect wirelessly using WDS. This causes the AX's Ethernet port to be active for the sling box. However using WDS cuts your available wireless bandwidth in half.
    Therefore I think i need this work around, is that correct?
    No

  • I have airport extreme and just purchased a D-Link DCS-932L home network camera.  D-Link says I need UpNp but the extreme doesn't support this.  Can I use port mapping?  if so anyone know how to set that up?  thanks

    I have airport extreme and just purchased a D-Link DCS-932L home network camera.  D-Link says I need UpNp but the extreme doesn't support this.  Can I use port mapping?  if so anyone know how to set that up?  thanks

    Since the D-Link DCS-932L is accessible on the local network via a web browser, you should be able to access this camera from the Internet if your router has a publically accessible Public IP address. If your ISP provides you with a dynamic Public IP address, you may want to use a DDNS service to make it easier for you to locate your camera whenever your ISP changes your IP address.
    Start the AirPort Utility > Select the 802.11n AirPort Extreme Base Station (AEBSn).
    Select Manual Setup.
    Verify that Connection Sharing = Share a public IP address is selected on the Internet > Internet Connection tab.
    Select Advanced, and then, select the Port Mapping tab.
    Click the plus sign to add a new port mapping.
    For Service, leave the default; this will change to "Custom" once you start entering port values.
    In the Public UDP Port(s) and Public TCP Port(s) boxes, type in a 4-digit port number (e.g., 8888) that you choose. In the Private IP Address box, type the internal IP address of your camera. In the Private UDP Port(s) and Private TCP Port(s) boxes, enter the appropriate port values that should have been provided to you by the camera manufacturer. Click Continue.
    In the Description box, type a descriptive name like "Internet Camera Access," and then, click Done.
    Click on Update.
    To connect to the shared Camera from a remote location using a Mac or PC:
    Start your favorite web browser.
    Enter either your Public IP address or DDNS-provided Domain Name, followed by a colon and the Public port number that you choose in step 7 of the previous procedure. For example: http://123.123.123.123:8888 or http://www.mydtdnsdomainname.com:8888

  • DMZ or a Port Mapping Range for A.E.???

    I'm currently having an awful time with a recent playstation purchase named SocomIII. It seems that in order to get my mic to work on it's online feature, I need to either open an array of ports, (i.e. 6000-7000) or enable DMZ. I can't figure out how to do either. To make matters worse, I just sent my powerbook out to be fixed (Don't ask ... my ac adaptor's male end snapped off into the powerbook's jack) ... so now I type to you from Windoze land .......

    Run the Airport Admin Utility. In the "Base Station Chooser" window that pops up, select Help->About Airport Admin Utility. What version of the utility is shown there? If it is older than 4.1, download the Airport 4.1 update from:
    http://www.apple.com/support/downloads/airport41forwindows.html
    ...and try following my instructions again.
    You can always look around in the version you are running - either after clicking on "Base Station Options" under the Airport tab, or under the Port Mapping tab. It's there somewhere!

  • Setup Port Mapping

    For the life of me, I cannot see anywhere on Airport Utility a place to set port mapping for an airport extreme. I need to setup port 80 and there is no documentation ANYWHERE online to do that. I see one site which shows a tab on airport utility that says port mapping, but I guess that was killed in an upgrade cuz it ain't on mine!!!! Any help would be great

    Try the following basic procedure to configure port mapping on the 802.11b/g AirPort Extreme Base Station (AEBS):
    Port mapping, under Leopard with the 802.11g version of the AEBS, will require at least two steps:
    1) Assign a static IP address for the host computer that will be accessed from the Internet.
    2) Configuring port mapping on the AEBS.
    1. Assign a static 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 AEBS'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>
    To setup port mapping on an AEBS, either connect to the AEBS's wireless network or temporarily connect directly, using an Ethernet cable, to the LAN port of the AEBS, and then use the AirPort Utility, in Manual Setup, to make these settings:
    2. Setup Port Mapping on the AEBS.

  • How do I use Port Mapping?

    b How do I use Port Mapping?
    (This document will assume that you are using and ABS/AEBS/AX as an internet router and have DHCP & NAT turned on.)
    Sometime you may want to offer access to a computer on your AirPort network to users on the internet, whether it be a web site, or for file sharing, or just remote access for yourself when traveling. If any of these sound like something you want to do, then you need to understand how Port Mapping works.
    b AirPort as Firewall
    Most of the time your AirPort base station will not let any traffic into your network which did not originate from your network. It will let everything out and replies to your traffic back in, but it will not let sessions initiated on the internet side of the base station in to your network. This is what is referred to as the "NAT firewall" capability of the base station and it provides effective protection for your network from the internet. What Port Mapping does is poke a hole in this wall to allow certain type(s) of traffic into the network and direct this traffic to a specific computer on the network. In the firewall world this is commonly referred to as an "inbound proxy" or "inbound translation" rule or "PAT" (Port Address Translation) in the router world.
    b The Need for Manual Addressing
    Since a Port Mapping entry in the base station configuration requires an inside private IP address to be specified, the computer to which to mapping entry applies should always have the IP address specified in the mapping entry. Thus, DHCP should not be used for a computer offering services on the internet as the Port Mapping entry will no longer work if the target computer's IP address changes. In general, an Apple base station's DHCP server will try to assign IP addresses in the 10.0.1.2 to 10.0.1.200 range. IP addresses above 10.0.1.200 can be Manually assigned to computers and other devices on the network up to 10.0.1.254. 10.0.1.255 is reserved (it is the broadcast address for the 10.0.1 subnet). To Manually set up the TCP/IP information for a Macintosh running Mac OS X, go to System Preferences -> Network and "Show" the appropriate interface (Ethernet or AirPort) and click on the TCP/IP tab. Select "Configure Manually" and enter the following information:
    IP address : 10.0.1.201 (or whatever address you decide to use)
    Subnet mask : 255.255.255.0
    Router IP : 10.0.1.1 (the AirPort base station LAN IP)
    DNS server : 10.0.1.1, or whatever DNS server IP your ISP uses
    After making these changes verify that your computer can still access the internet and local resources on the LAN before continuing.
    b Port Mapping a service
    In our example we will be hosting a web site on a computer which we have given an IP address of 10.0.1.201. Basic web sites are accessed using the HyperText Transport Protocol (HTTP) and this protocol typically uses port 80 to communicate. In order for others to see the web site, we must configure a Port Mapping entry in the base station configuration to not only allow the web browsers in, but to tell the base station what IP address the web server is using. The Port Mapping entry has three parts: Public Port, Private IP, and Private Port. In this case you would use the following values:
    Public Port : 80
    Private IP : 10.0.1.201 (this is the computer hosting the web site)
    Private Port : 80
    In order to access the web site from the internet, users must reference the base station's WAN port public IP (determined by looking at the base station configuration summary page in the AirPort Admin Utility). Since this address may change over time, you might want to use a Dynamic DNS service to simplify connecting for your users.
    Sometimes the port you wish to use may be blocked by the ISP. In this case, use a different non-standard Public Port number for the service, but keep the Private Port standard. In the above example, if the ISP was blocking port 80, you could potentially use 8080 instead, so:
    Public Port :

    Public Port : 8080
    Private IP : 10.0.1.201
    Private Port : 80
    Your users would then have to enter "http://<publicIP>:8080/" (where <publicIP> is the public IP address of the AirPort base station) to access the web site.
    b Internal Access
    It should be noted that when accessing these services from within the network you cannot reference the Public IP/Public Port, but rather you must use the Private IP/Private Port. Thus, "http://10.0.1.201:80/" in the above example.
    b Limits and Options
    There is a maximum of 20 Port Mapping entries that can be made in an Apple base station configuration. If you use an AirPort Extreme or AirPort Express base station there is an option which can be helpful in the case where you need many ports opened to a single computer. This is the "Default Host" option. When using this it is not necessary to use Port Mapping at all as all ports will be opened to the specified "Default Host". This is found in "Base Station Options". The default IP address for the "Default Host" is 10.0.1.253. You may change this IP address. The target computer must be Manually configured as specified above with the same IP address. Since all ports are now open to this computer, you should enable and configure the Mac OS X firewall on the default host computer to protect it from intruders.
