HINT: Turn off Firewall to enable Internet Sharing

it only took 2 hours of trial and error, but I am finally able to access the internet from my iPhone via my father's iMac (Intel Core 2 Duo, purchased in May 2009).
turn OFF the Firewall!
setup:
iPhone 3.1.2
iMac 10.6.2
Internet Sharing On: From ethernet, To Airport
cheers.
(keywords: iPhone, Internet Sharing, Snow Leopard, Airport, Firewall)

mmm... I had actually edited my original post but it didn't stick.
rather than turn off the Firewall (not ideal as the man from Virginia has rightfully pointed out), turn off the "Block all incoming connections" option in Advanced options.
cheers.

Enabling 'Internet Sharing' disables my internet connection

Hi all, my desktop computer (iMac 27") is hooked up to the internet via ethernet cable/modem. Very simple configuration. I normally share the internet connection (password protected) that my other devices access via wifi.
For months this has been working just fine. today I've been having connectivity issues. I worked with my cable company to determine the issue. what finally solved it was disabling wifi, shutting down the modem & computer. Then boot the modem, afterwards boot the computer.
This worked great, I saw everything working in Network Diagnostics...
Then, I re-enabled Internet Sharing, with the same settings I've used for months, and I saw the connection disappear immediately in Network Diagnostics (Ethernet & Network Settings were green, all else red).
Rebooting the router didn't work. Restarting the computer with with wifi enabled didn't work. I had to disable wifi, turn off everything, boot modem, boot computer to get it to work again. Any time afterwards, where I enabled Internet Sharing the connection would break again.
Please help! Thanks!

Also setup DNS in the server and use that for LAN clients or you probably will have to change firewall settings to allow the use of a public DNS to-from LAN.

Can't enable Internet Sharing on my phone

Hello,
I have a Nokia Lumia 920 and every time I try to enable Internet Sharing I get the message: "internet sharing isn't currently available". I tried several things for a week now and I can't seem to find a solution. It's really frustrating.
Here's what I have done:
Took the SIM card off the phone and placed it on an Android phone. Enabled HotSpot and tested it with NO problems. This means my carrier supports tethering or sharing internet connections
Back on the Lumia 920 I tried lots of things, specially the trick explained in this forum, which is creating a new APN in the "access point" section, activating it, rebooting, and then re-activating the old APN. Didn't work.
I have also searched for an APN inside the CELLULAR section (in order to delete it), but I found only the Active network and no APNs over there
I have deleted all APNs inside the "access point" section, rebooted, and found the phone can still connect and navigate the internet even when there are NO APNs created at all! In this particular scenario I tried to enable Internet Sharing and nothing.
Please any hint or lead will be greatly appreciated. It's very frustrating.
Thanks.

McClausky, if your Wi-Fi is enabled and your are not in flight-mode: Please, give us the name of your network operator and that 7-letter code on the label on your phone (product-code). Perhaps it is the combination of both which creates this trouble. Are you connected to another Wi-Fi while starting the Internet sharing feature?

Difficulties enabling internet sharing

For months I've been having problems enabling internet sharing from my ethernet sharing over airport. Everything appears to be configured correctly, and when I check the "Internet Sharing" box in System Preferences > Sharing, the green dot is displayed next to Internet Sharing: On, but system.log shows:
Jul 2 09:41:42 Musa com.apple.launchd[1] (com.apple.InternetSharing[7708]): Exited with exit code: 1
Jul 2 09:41:42 Musa com.apple.launchd[1] (com.apple.InternetSharing): Throttling respawn: Will start in 10 seconds
A workaround that worked in perhaps 50% of cases was to make sure that Airport was off, and then check Internet Sharing, enable Airport when asked to, and finally click "start" when asked "Are you sure you want to turn on internet sharing?"
But this works less and less frequently.
Any advice that could be offered would be appreciated.

The fix was to erase my hard disk and restore a cloned backup.

Trouble enabling internet sharing on my server

I'm setting up my first server (10.4 on a mac pro).
Under Sharing Prefs, I can't find the tab that I would normally use to enable internet sharing.
I'd like our external internet line to go into Ethernet1 and our network switch to plug into Ethernet2.
Thanks!

Hi Jen. My daughter just compleated her nursing program and is now working as a full time nurse. Focus and study hard and soon you will be there too. Now to the problem at hand. I have the same problem. I gave up on it and satisfied myself with my iPod without the upgrade. Reason being I've read so many posts of people having problems after the upgrade. But I'm sure other factors are involved. Nevertheless here is the fix most say works to solve the problem: What ever virus protection you have installed on your computer, disable it. Then try to install the update. After that enable the protection. I had Kaspersky, and it does it's job well. The thinking is, the virus protection is blocking the upgrade. Hope this works. Charlie

Unable to establish TCP connection when enabling internet sharing (Phone acting as hotspot)

I have developed a small .NET Desktop application which hosts a TCP service. In addition, it sends UDP Multicasts to anounce that service.
Service consumer is a Phone 8.1 app, which listens for these UDP multicasts and when it receives such a multicast, it creates a TCP connection to the service.
The following snippet shows how the Phone 8.1 app listens for UDP packets and then connects via TCP
const string UdpPort = "42";
const string TcpPort = "43";
const string MultiCastIp = "224.5.6.7";
const int TimeoutForServerLookup = 10000;
//-- listen for UDP multicasts
HostName hostNameOfServer = null;
var udp = new DatagramSocket();
var clientFound = false;
udp.MessageReceived += delegate(DatagramSocket sender, DatagramSocketMessageReceivedEventArgs args)
try
hostNameOfServer = args.RemoteAddress;
catch (Exception ex)
s_Log.Error("Error in handling UDP packet", ex);
await udp.BindServiceNameAsync(UdpPort);
udp.JoinMulticastGroup(new HostName(MultiCastIp));
var waitedTimeInMs = 0;
const int delayInMs = 250;
while (waitedTimeInMs < TimeoutForServerLookup && hostNameOfServer == null)
waitedTimeInMs += delayInMs;
await Task.Delay(TimeSpan.FromMilliseconds(delayInMs));
udp.Dispose();
//-- we now have the adress of the TCP server (hostNameOfServer)
//-- connect now to the server. this works when being in a "normal" WLAN, does not work when the phone is the hotspot
var socket = new StreamSocket();
await socket.ConnectAsync(hostNameOfServer, TcpPort);
This works well when the Desktop computer and the Windows Phone 8.1 are within the same WLAN. For some customers it is important that this also works when the Windows Phone 8.1 acts as hotspot (by enabling internet sharing on the phone) and the desktop computer
(or Laptop) connects itself to this WLAN. In this scenario the Phone 8.1 still receives the UDP packets, but when trying to connect via TCP, the connection attempt fails.
Any ideas how to get rid of this problem?

Have you tracked down if the phone actually sends the TCP connection to the desktop? I'm feeling that this is a firewall issue that shows itself when the firewall zone changes (public/private/domain).

Some folks have discovered that changing their DNS service fixes FaceTime connection issues.
The ideal way is to configure your modem/router with DNS service, but often settings in System Preferences/Network/Advanced/DNS on your Mac will override the router settings. Try either of these;
OpenDNS
208.67.222.222, 208.67.220.220
Google Public DNS
8.8.8.8, 8.8.4.4

I can't get artwork, I get a -609 error. I have tried turning off firewall and antivirus. Theewindows firewall is set to allow itunes anyhow. Any suggestions?

Perhaps try the "Error -609" section in the Specific Conditions and Alert Messages: (Mac OS X / Windows) section of the following document:

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

Hello,
This seems not related to SQL Server but more related to Fusion or a missing DLL. The following resources may help you:

How can I turn off access to the internet at scheduled times?

how can I turn off access to the internet at scheduled times? I use an Airport extreme and several units to extend the range. Kids have multiple devices that I don't want on the network at certain hours. On the other hand, ideally, my wife and I would like to be able to access the internet with our devices after the kid's bedtime and during their school study time.

Cannot enable Internet Sharing on ATT Lumia 900 du...

I have a Lumia 900 in the US. It was only sold by ATT in the US. I however am not with ATT, I'm with Straight Talk, an MVNO. When I try to enable Internet Sharing on the phone it pops up a message saying I need to contact ATT. I have no business relationship with ATT and they cannot help me. I would like to remove this message so I can get Internet Sharing working on my phone. The phone is unlocked, but that didn't seem to make the message go away.

Ok after feeling very positive that this was now going to work I can report that my call 611 ATT notification is now back and the internet sharing does not seem to want to be available.
Other observations that are worth noting.
1) You need to configure the internet APN using Nokia Network Setup with the fast.t-mobile.com and the MMS with the epc.t-mobile.com or the internet connection cuts out every time you hit LTE speeds. So thats only three entries required in the config the last being the MMSC address available on the T-mobile site.
I am enjoying my handset on T-mobile with the internet speeds, I would still like to use the internet sharing so I will continue to drill down and look or a way around the issue.
