Open udp port on Wireless Network

I have a WLC2106 with 6 APs model 1240AG. An application uses port 11050 UDP for license management. The client send a broadcast on this port looking by the server, because this information is NOT passing through, the connection can't be established. With the original network (3com), there is no any problem but with Cisco network, this particular port appears to be closed. How can I confirm the AP is blocking this port? How can I open it? I tried with an ACL but the problem was not fixed.
thanks in advance.

Eric:
Thanks so much for your support. Finally I have the application working.
I found the problem was not with the UDP port alone, the problem was with all broadcast (your tips give me ligth).
Besides the "Broadcasting Forwarding" option I changed the "Ethernet Multicast Mode" to Multicast.
The key was this paragraph in the release notes:
Re-enable Broadcast after Upgrading to Release 4.0.206.0
In software releases 4.0.179.0 and earlier, broadcast and multicast forwarding were both controlled with a single global flag that enabled multicast. Beginning with software release 4.0.206.0, these functions were broken into separate configuration flags: one that controls broadcast and one that controls non-broadcast multicast. If you have multicast enabled in software releases 4.0.179.0 and earlier, the broadcast flag is left disabled after upgrading to software release 4.0.206.0. As a result, some applications that rely on broadcast do not work after the upgrade.
After you upgrade to software release 4.0.206.0, use this CLI command to re-enable broadcast:
config network broadcast enable
When re-enabled, broadcast uses the multicast mode configured on the controller.
To be honest I am not very clear how the multicast mode is related with the problem, but now I can see all the broadcast messages passing through wireless network.
Thanks a lot

Open UDP Ports on AirPort Extreme

I need to open a few UDP Ports on my new AirPort Extreme so that the software that is running on my network can access the internet over those ports and the software can be accessed from the internet as well. I can find in the AirPort Extreme manual how to open TCP ports but not UDP. I have the list of ports I need to open, but can't find where to configure them in the router firmware.
I would like help on where to configure these ports. Thank you.

If you are using the Airport Utility on the Airport Extreme N Base Station, the port mapping screen should look like what you see on page 56 of the manual "Designing Airport Networks" found at:
http://manuals.info.apple.com/en/DesigningAirPort_Networks_Using_AirPortUtility.pdf
...and it clearly shows how/where to specify UDP and TCP ports.

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..

Hi,
à
I need the UDP PORT 445 listed on SYSTEM Process.
à
Warning SYSTEM's UDP port 445 is not open or listening.
Based on your description, I’m a little confused with this issue. Please run following commands with administrator
permission and monitor the result. Would you please check and confirm whether any process listened the UDP port 445?
netstat –ab
netstat -a | find /i "445"
In addition, I noticed that you use Syshelp (Symantec validation tool) to check. I suggest that you would post
the warning message in Symantec Forum and confirm this issue. I believe we will get a better assistance there.
If anything I misunderstand, please don’t hesitate to let me know.
Hope this helps.
Best regards,

Open TCP Ports on 9216i

We are auditing open TCP ports on our network equipment and discovered a number of open TCP ports on our 9216i. Is there any way to tell what the open ports are used for and shut them down if unnecessary? The show tcp command is not available. show tech did not reveal anything.

There is the standard set of ports that are open for mgmt by ssh, telnet, and SNMP v2 or v3. Additionally, there is port 80 open so you can point web browser to it and get the FM code. The list is as follows.
Common to all applications
* SSH 22 (TCP)
* TELNET 23 (TCP)
* HTTP 80 (TCP)
* SYSLOG 514 (UDP)
Fabric Manager Server and Performance Manager
* SNMP_TRAP 2162 (UDP)
* SNMP picks a random free local port (UDP) - (can be changed in server.properties)
* Java RMI 9099, 9199 to 9299 (TCP)
Fabric Manager Client
* Java RMI 9099, 9199 to 9299 (TCP)
* SNMP picks a random free local port. (UDP) or 9189 (TCP) if SNMP proxy is enabled (can be changed in server.properties)
Device Manager
* SNMP_TRAP 1163 to 1170 (UDP) (picks one available in this range)
* SNMP picks a random free local port (UDP) or 9189 (TCP) if SNMP Proxy is enabled (can be changed in server.properties)
You can shut off telnet in lieu of ssh in the configuration. Also, it is possible to use access-lists on the mgmt ports to limit IP addresses/ports/etc. Also, don't forget that the IPS ports will be listening for FCIP and ISCSI if enabled.

LRT224 Dual Wan - Opening up Ports

Hello,
I am installing a new VoIP system on our network and the company advises us that we need to open UDP Ports 10000-60000 and TCP port 80 and 443. I believe TCP Ports 80 and 443 are already open according to the test I have run but I need to open the UDP Ports.
Can anyone advise me how to do this? We have roughly 8 computers on the network and I need to open the ports for all computers.
Thanks

That sound right.
In your One to One Nat set your Private Range Begin to something like 192.168.1.50 and the Range Length to number of phones. Remember that you don't include IP addresses in use by WAN ports in Public Range Begin.
Use IP & MAC binding to assign the IP addresses to the workstations.
In this case you might not have to open ports because of the One to One NAT I'm not sure.
Please remember to Kudo those that help you.

Track UDP ports

Hi,
How can we check opened UDP ports on Solaris 10.I run following command to check all open UDP ports but it is not displaying all
netstat -a -P udp but I cant see 514 udp port which is being used by syslog.
asqcsat:/ # ps -ef|grep syslog
root 11836 2306 0 Dec 05 ? 30:07 /usr/sbin/syslogd
root 17025 17019 0 15:14:26 pts/37 0:00 grep syslog
asqcsat:/ #
asqcsat:/ # netstat -a -P udp|grep 514
asqcsat:/ #
Regards,
RTA

Well, since the port is, as mentioned, defined in /etc/services, it will show up in 'netstat' as 'syslog' rather than '514'. Hence, try and run
netstat -a -P udp | grep -i syslog
If you still don't see anything, perhaps logging of remote messages are disabled.. In which case you should check /etc/default/syslogd and svccfg for the system-log instance.
If the port is opened by syslogd, you should also see it if you run:
pfiles <pid of syslogd>
.7/M.

Wireless CCTV - need to open a port

Hi All;
I have a wireless monitoring system (CCTV) for my home that can be accessed remotely though my IPhone or IPad when I am away.
It works great while I am at home on my wireless network but I cannot get access when on a remote Wi-Fi.
Apple Store here says I need to open a port in my Time Capsule to allow access when I am outside my network.
Anyone have instructions or can step by step it for me?
Thanks in Advance.
Mark

Thanks for the reply William;
I actually contacted the manufacturer and they sent me a step by step instruction including, as you suggested the ports that the cameras use.
Once we get through this Christmas season ... will get it all set up.
Thanks again

Our IT Director will not allow the appropriate TCP and UDP ports to be opened on the district WAN

I have about 30 Apple TV Units and our IT Director will not allow the appropriate TCP and UDP ports to be opened on the district WAN. When our teachers try to log on to Apple TV to broadcast lessons, websites, etc., they are booted off the network after about 20 minutes.
Any ideas for how I might solve this without having to hard-wire the Apple TV Units?

Honestly, you do not.
Either the IT director will cave and allow the appropriate ports or it doesn't work.
Hard wiring the ATVs will not rectify the problem.

My Network of Macs keep broadcasting to udp port 8612 every few seconds

This problem was answered nicely by "Hunter3740" and Apple archieved it....It is still valid/needed for Mountain Lion!
https://discussions.apple.com/thread/2464784?start=0&tstart=0
Here is how to stop your Mac from broadcasting to udp port 8612 every few seconds without using a Terminal WIndow:
Under Utilities (In Applicatiopn Folder) launch the Activity Monitor, then show "All Processes" and find the one named "CIJScannerRegister.app" and hit the Stop Sign (Quit Process).
Then follow this Machintosh HD--->Library-->Image Capture--->Support--->LegacyDeviceDiscoveryHelpers---->then throw "CIJScannerRegister.app" in the trash and empty it.
Bingo...the broadcast stops.
Apple: Can you fix this turd with a system update?

Is there a chance that someone has installed some kind of
software on the computer that is trying to "call home?"
The app known as Little Snitch can tell what may be in there
and if it is responsible for these odd network calls out.
How is the port security set up in the Mac? And why would
those ports need to be open unless there was a real purpose?
With my Macs, all of the ports in Firewall are closed to access
except for the Network Time Server to keep the clock correct.
{Some are used to share files between computers, & to chat; etc.}
Do you have more than two user accounts in the computer, and
if so, is your Admin account only used to update and maintain
the OS X & to install apps for other users? The levels of security
in Mac OS X can be controlled; and such odd port calls if or when
there is no need, are signs that something is not quite right.
Have you looked into the Console utility to see what is causing the
hang at those time intervals you know this has happened? There
are several different logs and reports in there; some won't apply.
Do the children who use the computer, have access to or know the
Admin account's password? A second user, from their account, can
install software and do other things, if that password is available.
I noticed you had a similar post last month that appeared to go without
a reply; now it is locked and can't be replied to anyway. So this issue
has been going on for some time. What may have happened in the past
year or so, to start this issue in that computer? Something, for certain.
Good luck & happy computing!

Can I use the Airport Express to connect to a Linksys Wireless Network and then use the Ethernet port on the Airport for a wired connection to a device for internet access? Would I be able to then also use that Ethernet pt to a Ntwk Hub for more wired c

Thanks for the help. Looked but not clear on what I am trying to do as being possible. Can I use an Airport Express to connect wireless to a Linksys Wireless Router, such that I can then use the Ethernet ports on the Airport to either connected to a PC wired, or even use a hub off the Airport Express to allow multiple wired connections to it?
I am not looking to have the Airport Express extend my wireless network, just connect to it and provide me wired connections in a different location from where my Linksys Route is located. Would prefer to replace Linksys with all Apple, but just not possible financially yet. Thanks for the help.

If the AirPort Express Base Station (AX) is an 802.11n model, then yes, you can reconfigure it as a wireless Ethernet bridge. In this configuration, the AX would join the wireless network provided by the Linksys router and its Ethernet port would be enabled for either a single wired device or for an Ethernet hub or switch for multiple devices.

I have Fios. I have the TC connected via ethernet to the Fios router. TC WAN port ethernet to Fios Lan port. Then I just have the TC create a wireless network that is different than the Fios wireless network. How do I set up an Airport Extreme to the TC?

The Airport Extreme is a 4th Gen unit. I just want to keep the TC wireless name to go further through my house.

The Ethernet connection will be from one of the LAN <-> ports on the TC to the WAN port (circle of dots icon) on the AirPort Extreme.
Then you can use AirPort Utility - Manual Setup to configure the AirPort Extreme as follows:
Click the Wireless tab located just below the row of icons
Wireless Mode = Create a wireless network (Not "extend a wireless network" as many users incorrectly think)
Wireless Network Name = Same name as your TC network
No check mark needed next to "Allow this network to be extended"
Radio Mode = Automatic
Channel = Automatic
Wireless Security = Same setting as the TC network
Wireless Password = Same setting as the TC network
Confirm Password
Click the Internet icon
Click the Internet Connection tab
Connect Using = Ethernet
Connection Sharing = Off (Bridge Mode)
Update to save settings and restart the entire network
Computers on the TC network will now be able to move to the area where the AirPort Extreme is located and not have to "switch" networks. This is known as a "roaming" network.

Airport no longer connects to OPEN wireless networks

Lots of people seem to think that their airport keeps dropping the connection to OPEN wireless networks because of the 2008-001 airport update. That is probably only true for a Macbook 2,1 (aka Macbook Core 2 Duo).
I had the issue on my Macbook 1,1 (aka Macbook Core Duo). I wiped the system clean. Re-installed OS-X. Applied all updates BUT:
1. Airport 2008-001
2. Security update 2008-002
I also downgraded the Airport firmware to 2007-004 (aka version 1.1.9.3).
Technically speaking this should have resolved the issue but it didn't.
Why do I believe it should have resolved the issue? Because the same approach worked on the Macbook 2,1 and they both have the exact same Airport card.
Now I have no idea how to get it fixed - I think I have tried every possible way. There doesn't seem to be any way to contact Apple coz I don't have a support contract.
But hey, do I need a contract? Apple broke this for me ... they should fix this. I am about to post this as a tech article on engadget and other places because there are SO many people suffering from poor testing on Apple's behalf.
Apple, please respond.
Thanks.

Visited the "genius" bar this afternoon - what a trip!! The guy said this is a Verizon issue, period. I was like you must be kidding, there are SO many people out there who got affected and not everyone uses verizon ... he actually got pretty mad and said you should be using mac hardware (router) and secure network. I even told him my second Macbook is working fine on the same Verizon network. This is their new location in the Northern VA area at Fair Oaks Mall.
I would call that guy anything but a genius, what a waste of time. This was my first and last trip to a "genius" bar.
If anyone comes across any new ideas, please share.
Thanks.

I have bought a TC to extend the range of the wireless network in the house and would like someone to explain the best way to do this? My combine router/modem is supplied by Movistar(in Spain) model Xavi 7958 router ADSL with four ethernet ports.

What is the best way to extend my wireless network in the house using a TC? I currently use a combined router/modem supplied by Movistar(live in Spain) model XAVI 7958 router ADSL with four ethernet ports. What is the best configuration and can you explain what is meant by bridging and which is best to bridge for signal strenght TC or Xavi modem/router? Have ipads, iphones, apple tv...etc and want a connection them all in the whole house which, not just downstairs, to our wireless network.

You cannot wireless bridge Apple to non-apple router.. so that is out.
The only way you can do this is run ethernet or EOP adapters.. and place the TC in a location where the other apple idevices can reach it.
If you want to repeat wireless with apple routers you have to use another apple router next to the modem.. plugged in an running as an AP.
Basically the TC is the wrong piece of equipment unless you want Time Machine backups.. take it back and buy a universal repeater.. not apple. Or buy more apple stuff like an extreme or express.. one apple router is useless to you without running ethernet.
