Airport Extereme 6.1: I can't open those ports I wanted to!

Hi everybody!
I would like to open some ports in my Airport Extreme 7.6.1. (software 6.1). Those ports are for example EyeTV 2170 and VLC 5900.
I have Airport utility and I have tried to change port settings at network section. I have changed at network port settings (presetted and made by myself) without success. I don't understand private ip-address and what it should be but I can't understand what I am doing wrong? Especially if there is available preset settings?
Local network is working very well but when I'm outside my network all goes wrong!
Those apps I have tried to are MyMac and Scany.
Scany indicates that dispite I have opened some ports those ports are not open and MyMac can't get connected to my computer. Yes I have enabled screensharing and remote login what so ever.

By the way, I am with the same problem again. If anybody has time and a version of Labview able to do this, I would be very grateful. The link is below.
The manufacturer's web site has a newer version of the driver for that instrument. It's not written all that well, but at least it uses VISA, unlike the VI you uploaded, which uses old GPIB functions. The library the manufacturer provides is in 5.1, which unfortunately you still cannot open in 8.6. Attached is the library in 8.2. For what it's worth, the VI you uploaded in 8.2 is also attached.

Can I open a port range in the firewall for one host?

Can I open a port range in the firewall for one host? In other words, I want to be able to open ports 54001 to 54050 to allow one remote host in my LAN to access that port range in my Mac Server. Is this possible? Currently, the only option I see is to open individual ports for all external hosts (eg http or https)
Thanks in advance!

Which version of OS X Server are you using?
Server 2.2 and earlier includes an interface to a software firewall that can be configured to open specific ports very easily. Descriptions of how to configure the firewall can be found in the documentation for these versions.
Server 3.x no longer has an interface to the software firewall - it is still there, but you need to use other methods do configure it. A popular example of such a method is the icefloor utility.
Apple suggest that for Server 3 you delegate firewall duties to an external router. Server 3 includes the ability to configure the firewall component of Apple Airport routers 'automatically'
if you connect a machine running Server 3 directly to an Airport Router the router appears in the LH pane in the Server.app window (usually second line, below the entry for the server itself), and you can control what services are 'enabled' through the firewall there.
a more common solution perhaps is to use a non-apple router, and configure the firewall (and so open specific ports) through whatever control interface is provided for that router. There are many many kinds of hardware router you could use, and the control interfaces used vary widely - so you will have to consulting the documentation for your own router to work out how to do this.
If you post information about your software versions, and hardware configuration, it is possible that you can get more specific help with the tasks involved in opening the ports.
Hope this helps.

Tecra M1 - Modem doesn't work (can't open a port)

I have a problem: After reinstalling WinXP and drivers on my Tecra M1, modem doesn't function. It even can't diagnose itself - there always comes a warning: "Can't open a port (COM). It may be used by another device or application". I installed the latest Toshiba drivers for the modem, but nothing changes. How can I fix it? Looking forward for your advices!
Best regards.

Hi
Did you install the drivers in the right order? Not? So do it!
Did you install any additional devices or software which could has a bad influence on the modem?
Check the modem status in the device manger. Can you see any yellow exclamation marks?
Try to start the modem test within the Operating system.
Check the Modem function under
Start -> Control Panel -> Phone and Modem Options -> Modems Tab -> Properties -> Diagnostics
by pressing the "Query Modem" button.
If the Modem Information window contain a list of AT commands (including ATI2, ATI3, ATI4 etc.), then the modem is correctly installed. The ATI5 command ends in with the number for the selected Regional settings (for example Germany = 06).
To change the Regional Setting please use the Toshiba Internal Modem Region Select Utility.

Can't open local port

Hello all
I would be very grateful for some help with this problem,I haven;t been able so solve and i have spend a lot of time on it
I have written my own client RTSP code,from this i can set the client ports i want to recieve and send RTCP and recieve RTP,and can read in the server ports
So i have something like 157.190.181.36 60972 60973 client
157.190.181.36 6972 6973 server
To handle RTP i have used RTP socket player or RX and may other RTP reciver options,as in the java solutions etc ,so that i can recieve RTP and create a player
When i run them i get the same eror from all error can't open local port
Further information
I am on a LAN,but hav tried my set up disconnected from the LAN through a hub set up
I have tried opening the ports before callled the RTP players i.e
on the client side
DatagramSocket RTPsocket3= new DatagramSocket(60972);
DatagramSocket RTPsocket4= new DatagramSocket(60973);
Through sniffers
I know the RTSP messages are OK
I recive an ICMP message destination unreachable
I am connecting to darwin streaming server and i can connect to this and play through apple quicktime player or JM studioTHANKS IN ADVANCE!

Hey...
I'm having a similar problem, because i'm developing an application that its serving RTP audio context streams. So the application would transmit a playlist of files over RTP, and it works fine for one file, but when i try to give it a new file, i always get the exception "Can�t open door: ...". This error occurs on the line that is marked with *****.
I'm creating a processor for each file i want to transmit, for the same port and same IP address, so when the first file ends i close the processor and create a new one with the same properties, but with a diferent file...
I really nead this to work, so if someone could help me on this it would be really appreciated... Thanks in advance...

WRT54GC can't open UDP port

I can't open UPD port i check with PFPortChecker and TCP port is open and UDP port is not reachable i using win7 how to fix it ?

Which port no you are trying to open..?
For which purpose you are openning the port on the router..?
Uncheck "Block Anonymous Internet Requests" under Security tab and check..

RV042 can't open any port!

Hello,
I have a RV042 Dual Wan. Two internets balanced wow! who would've thought that the headaches were waiting patiently right down the corner.
I was working with a 2wire Gateway that came with my ISP. I was able to open the ports in order to have public access for my students and teachers to upload their work. All I had to do was to allow my server ip address to have access to different ports blocked by the ISP. I used
http://www.canyouseeme.org/ in order to verify if my port was open.
I bought the RV042 for various reasons like excellent content blocking, load balancing, quick vpn, among other. But I just can't open the port 80 while having having my two ISP connected with load balancing, not even while having only one modem connected.
I have resolved many issues using the protocol binding. I have tried everthing. I just don't undertand something.
Whenever I connect my server to my old router, "www.canyouseeme.org" tells me that my port 80 is open.
Whenever I connect my servet to the RV042-DW, my port appears closed.
So it's not any OS issues.
I've tried:
- To forward the TCP 80~80 port to my server static ip address... but failed
- To enable UPnP function with the same port... but failed
- To configure the port triggering with the same port.. but failed.
- To disable the firewall.. but failed.
- To use transparent bridge in the WAN1 with my 2wire Gateway... but failed
- To set up an account in DNS.ORG already had one, everythings is in green.. but failed.
- To change the configuration in my old 2Wire Gateway router to allow a DMZ zone so all ports are public... but failed.
- To assign RV042 router ip address in my old 2Wire allowing that specific address to allow certain ports to be public... but failed.
I have the Firmware v4.0.4.02 from DEC/11
HELP!
http://www.youtube.com/watch?v=TU7JjJJZi1Q

Which leads us to the second preoccupation. If I can't make port 80, or port 21 to be public then could i set a QuickVPN successfully?
Is it possible to bridge a RV042 Dual Wan to a RV042 V3 Dual Wan to bring 3 ISP's downstream loading balance into 4 outputs.?
First Router
1st ISP = 2Wire Gateway 1Mbps Down , 0.5Mpbs Up
2nd ISP = Same as 1st
Second Router
3rd ISP = Dedicated Internet access 2Mbps UP and DN
Would that produce a 3Mpbs Down, 2.5Mpbs up?

How can I open the ports with the Airport Extreme?

I have an Airport Extreme Base Station connected to a cable modem and I want to open the ports for the two Playstation 3's I connected to the Airport Extreme via Cat 6 ethernet cable. The first Playstation 3 will be used to play Call of Duty Modern Warfare 2 and the other Playstation 3 will be used to watch streaming movie from Netflix. Does anyone know if this can be done?

It is documented on Page 54 of Apple's "Designing
AirPort Networks Using AirPort Utility Mac OS X v10.5 + Windows" (direct PDF download link).
The public port and private port would be set the same value.

How can i open ftp port(s)?

Hi,,

What am I doing wrong? When I'm on the same network I do connect through ftp , but when I'm away home I can't .
Here's a print screen of my Airport Extreme configuration . Someone could help me please?

Port 5900 is for VNC (screen sharing), the WD will not support VNC. Leave that port alone.
What you want to to is complex to setup securely…
Enable ssh on the WD.
Fix the WD's IP local address on the router so that it is always the same (this makes port forwarding stable).
On your router open a port to use ssh…
Port 22 is 'privileged' & is often scanned by bots just like port 21, choosing another port will reduce that exposure to an extent (a determined hacker will still know ssh is running on this port).
Pick port 23895 or something else high (over 1024) that is the external port to use to 'dial in'. The router needs to direct to the internal port 22 on the WDMyCloud.
To test the connection use ssh in Terminal (do this from inside & outside the WD network)…
ssh -p 23895 username@external-IP-address
accept the 'ID' if they match (first time only, unless the IP changes)
enter password for username
This allows you to run commands or browse files via Terminal commands etc.
Type exit & hit return to leave the remote session.
You can also use apps like Panic's Transmit to mount the share points over ssh or sftp - frankly it's easiest to stop here - Transmit has a 'mount remote disk' feature that basically does the same as Connect to server in Finder. Use ssh or sftp as the settings & it will be secure.
Mounting remote in Finder
If you want to mount the disk via AFP in Finder you need to use 'ssh local port forwarding'. The principle is to forward a custom local port through the ssh connection to the AFP port on the WD.
This will setup the forward…
ssh -p 23895 username@external-IP-address -L 22548:localhost:548
Note -L is 'local forward' here it uses local port 22548 on localhost to connect to 548 on the remote end.
Then you can connect in Finder to localhost.
afp://username@localhost:22548
You are connecting to the local port 22548, which is actually a tunnel to the WD's port 548.
Some things to note.
You need to disconnect & kill the ssh connection when finished, otherwise the local forwarded port will remain in use, this prevents connections & makes it frustrating.
Your external IP address may change depending on your ISP & internet service type, whatsmyip.com will help you see changes but only from inside the network. dyndns.com or no-ip.org can help with this issue. Either the WD or the router should be made responsible for updating any dyndns records.
I haven't mentioned setting up ssh keys, there are many guides on the web. Once keys are setup you can disable password login via ssh on the WD, just be aware that if the keys do not work you get locked out of ssh - potentially catastrophic on these NAS's that have limited access. Transmit will use keys saved in your user account.
Local forwarding seems complex (it is) but once it works you can save the commands in two scripts, one to connect & mount the disk(s), another to disconnect & kill the ssh connections. It makes life easier. Transmit skips the need for these altogether.
I suspect that is very scary, sorry it is just complex to setup. Test locally is my advice (use the internal IP when inside), then move onto testing from outside. If you have an iPhone apps like Prompt or iSSH can allow you to test connections via cellular data which is outside the LAN.
I'll try to clarify if you have questions, but it's very difficult to troubleshoot via forums, so good luck

I can't access my iPhoto or Photos libraries with Elements 11. Elements say it can't open those files?

I am using Elements 11 on a Mac. I cannot access any of the pictures in my iPhoto or Photo libraries. Elements says it cannot open those files. There must be a way, but I can't find it. I'd appreciate a solution. Thanks.
Friarahs

No, you should never poke around in the iphoto library from outside iphoto. That's the fast track to corrupting it and losing all your pics. If you want to use iphoto with PSE you can either set PSE as your external editor and send the photos from iphoto or do it the way you have to do it with Photos (no choice with Photos):

Linksys EA3500 and QSee CCTV DVR, can't open any ports

Hi everybody,
I just set up everything, and I am able to view the cameras from inside the network, but when trying to view them from outside it appears offline.
I have tried to follow all the guides to open ports, tried 80,81,85, 6039 etc but canyouseeme always tels me that the ports timed out. I enabled DMZ for the specific MAC address of the dvr also.
I'm going crazy!
Is there anything I am doing wrong?

Are you using the Linksys smart wifi feature or just the classic page? If you are using the Linksys smart wifi page then you can use this article: How to set up port forwarding on the Linksys Smart Wi-Fi Router using the local access interface
If you are using the classic Linksys page then you can use this article:
Setting up single Port Forwarding on Linksys Wi-Fi Routers and Smart Wi-Fi Routers
Make sure to disable the filter anonymous internet request under security tab of the router.
Make sure to get public ip or wan ip on the router’s status page.
The ports 81, 85, 6039 and other camera related port numbers should be open behind your modem. If they are blocked by your ISP then you have to ask them to open these ports. You can use this port checker ping.eu to verify if the port is really open. Once all ports are open for your camera, then you should be able to access it remotely.

Can't open FTP ports in Airport Extreme router

Hi,
I have three computers networked at home with an Airport Extreme serving as a router to the internet. A couple days ago I set up an FTP server on one computer (Ubuntu Linux). It is running properly and I CAN get into the FTP server via the local area IP address (10.0.1.101). However, no matter what I do I can't get the Airport Extreme to forward any FTP connections from outside. I have port forwarding set up correctly and working correctly for echo (7), daytime (13) ssh (22) http (80) nfs (2049) and vnc (5900). However, even though I set ports 20,21 to be forwarded to the correct computer nmap they are NOT open. (nmap doesn't see them, and telnet to ports 20 or 21 is refused. However nmap on the server locally (ie as localhost) shows that these ports ARE open on the server, and ftpd IS running.) Neither of my mac laptops has ftp file sharing turned on in the preferences (not like this should matter anyway). The Airport Extreme just plain does not open or forward anything to ports 20-21.
I also tried putting the FTP server on a different port (2121), but this doesn't work either. Is this just Apple playing nanny and not allowing me to run FTP for my own good? I have been troubleshooting this for two days and no closer to a solution. I hope someone can offer some advice.
Craig

I believe that I've found the problem with the AirPort/Time Capsule (version 7.3.1) support for FTP.
For whatever reason, when an FTP connection comes-in from the WAN, the NAT translation is reporting the IP address of WAN side of the router instead of the IP address of the actual system connecting from the Internet.
I confirmed this by setting up a FTP server on my Linux machine and watching the connection to the FTP server from the internet. When you perform a:
netstat -an | grep ':21 '
from the Linux shell, you see that the IP address that is connected is your own WAN IP address of your AirPort/Time Capsule.
Apparently the AirPort/Time Capsule recognizes the connection is an FTP client and manipulates the connection in such a way as to report the wrong IP address that is connecting to your FTP server.
This isn't a problem, unless you're using /etc/hosts.allow and /etc/hosts.deny to have port wrapper permit only listed IP addresses to have access to the FTP service. In that case, all connections seem to come in from your router's WAN IP address, so there's no way to distinguish where the connection is coming from.
Apple needs to take a closer look at the version 7.3.1 for the Time Capsule (not sure what the version is for the AirPort Extreme) and fix the reported IP address from the WAN side connection.
