Firewall and Internet Sharing dont mix

After talking to AppleCare, looks like my firewall is not letting me sync to my AppleTV because I am using Internet Sharing to connect it to my Mac Mini (PPC) and get to the internet through the Mini's ethernet. I have no Airport Express or Extreme.
He says that enabling "iTunes Music Sharing" only opens that port for ONE of the network connections (ethernet or airport), but not both. Hence AppleTV wont sync with the firewall on. Only with it turned completely off.
Anyone out there know different? Or know of a workaround to open the port for both networks somehow? (sorry if I don't speak the wireless-magic lingo well)
This is my first wireless device- so I'm a noob. Sorry.

I have had a ton of trouble syncing.
Can you see Apple TV in your preferences?
Does Apple TV start syncing and then drop off?
If so, open iTunes and quickly click on Apple TV and you will see the sync start. Then quickly Click on iTunes/Preferences and then on the Apple TV tab. Leave that small window open and then the sync will keep going.
Weird butmay help.

Error message about firewall and internet sharing

hello all i have a question regarding the use of firewall and internet sharing.
I have a PMG5 connected to internet through Airport. I've linked an Xbox 360 via the built-in ethernet port in order to access Xbox Live. I had to open specific UDP ports on the OS X firewall but it now works fine. However, in the Sharing Preference Pane, Internet Tab, i still get an error message saying that my Internet Sharing is disturbed by the settings of the firewall and sharing services, it says that i did not activate "personal web sharing" in the first two tabs...but i DID ! And there's no way to get rid of this error message.
I know I know some may consider it's not a real problem because it's just an error message while the connection actually works fine but well, I tend to hate error messages when they're not supposed to show up. So if anyone know the answer, thanks in advance...
Good day to everyone
Vince, Paris...

sorry about the delay in replying, was kinda busy
well trashing the pref files was useless and i tried with another user, same thing. As for the second opinion, the problem was not about which port was used cause as i said the connection sharing works fine and anyway it was the correct port that was checked, it's just that i get an error message while there is no apparent error and everything works fine, i'm told that personal web sharing is not enabled but it is...
Anyway as i said, it's probably not a real matter, as long as it works...which brings me to another thing. I've created a special protocol in the firewall to enable a proper dialog with the xbox. it's basically the same thing you do for ichat AV when you have video connection problems, you track down the concerned UDP port using terminal, you allow traffic and all... The protocol for the xbox worked great for some days, but now it seems it's not enough, the game set keeps trying on another port and i constantly have to update the protocol or deactivate the firewall...and enabling back all UDP traffic is not enough to solve it.
In a way i think everything is linked, the initial error message when everything was fine and the current trouble. Any idea?
thanks
Vince

Help with Firewall and Internet Sharing

I’m trying to use my Mac Mini with an Airport Extreme card, which is connected to the internet using Siemens Speedstream 4100 DSL modem, for Internet Sharing with a Windows (work) laptop.
So, in the Sharing preferences panel:
Share connection from: Built in Ethernet
To computers using: Airport
I get the warning message:
Other settings may interfere with Internet Sharing.
The ‘More Info’ button gives the popup message:
Your firewall settings will prevent computers sharing your internet connection from browsing the web. Enable Personal Web Sharing in the Services pane to allow computers sharing your connection to browse the web.
I do that, turn the Airport card on, and the laptop can see the network, but can’t connect.
If I turn the Firewall off, then I can connect fine, but then I don’t have a Firewall. Isn’t that risky if I’m using DSL? How can I do the internet sharing and still protect my computer?
I realize I could buy a router with a built-in firewall, but isn’t there a way to set up the system using what I have?

We just need to figure out what port is needed. I'd goto Sharing>Firewall>New>Port Name... Other, and try Port 53 both UDP and TCP.
Oh, and when you say the PC can't connect, could that just mean it can't browse?
On the PC, put the IP of the Mac in DNS servers, or...
208.67.222.222
208.67.220.22
Well, I'm unable to set the DNS server addresses, as this is a work computer and I don't have the administrative privileges.
How bad is it to just turn the Firewall on the Mac off when I want to use the connection?

"Firewall" and "Internet" buttons missing from "Sharing" preferences page

Hi,
I recently upgraded two servers to 10.4.3 (one was running 10.2 and one was running 10.3). On both servers now the Firewall and Internet tabs are missing from the Sharing preferences. Also, under the list of services on the Sharing prefs, there are only three services listed:
REmote Login, ARD, and Remote Apple Events. No other services are listed.
I found this problem because something in the firewalls changed and was blocking access to the servers via ARD. If I stop the firewall, then ARD works. So I wanted to go into the firewall settings and open up the ports required by ARD. Lo and behold, no Firewall tab on the Sharing page!
I've searched everywhere for info on what could make most of the services disappear, along with the Firewall and Internet tabs. But I can't find anything. Any ideas out there?

A call to Apple confirmed that the majority of services on 10.4 Server are now handled through Server Admin rather than through the Sharing preferences window.

Help with LTE and Internet Sharing for BUIlD Lumia...

Nokia,
I received the Lumia 920 when I was at BUILD 2 weeks ago. I followed the instructions and the phone mostly works on AT&T. I had a 900 so I assumed my LTE and Internet Sharing plan would easily transfer. Unfortunately that does not seem to be the case. I called AT&T gave them my IMEI number but it's not in their system and is not recognized as a Lumia 920. Because this is not an "AT&T phone" they wouldn't do much more to help. My data connection only ever shows 4G, never LTE as my 900 does and I cannot enable Internet Sharing even though it's on my data plan. I believe this is all controlled by the IMEI number.
Is there anything Nokia can do to help us? I can't imagine I'm the only one having this problem! I'm going to try again to see if I can get the issue escalated and maybe they can force the IMEI number to be recognized as a 920.
Thanks!

Sorry I never came back to update. The fix, as has been noted already, is to make sure AT&T has your IMEI as another 920 or your old 900 so that you get LTE (which appears as "4G"). Then, in the Nokia Access Point config setting (under System Config), make sure LTE2 is selected, then install an additional keyboard (I tried both Spanish and Chinese). This will force an OTA update that seems to enable Internet Sharing. I had to redo it a second time when I updated my Nokia Access Point app last week, but I just re-installed a NEW keyboard and got Internet Sharing back. It hasn't gone away since, contrary to what others have experienced. For more info (and where I found the fix) see this XDA thread: http://forum.xda-developers.com/showthread.php?t=1971997

Airport and internet sharing turns off by itself

Hi everyone, I have an imac that I purchased earlier this year, and I use internet sharing to get internet for my ipod touch. Until a few months ago, this worked fine but now airport and internet sharing turn off every time I restart the computer and I have to turn both back on every time. Is anyone else experiencing this problem or know hot to fix it?

Hi and Welcome to Apple Discussions...
Download and install the v10.5.8 combo update available here.
http://support.apple.com/downloads/MacOS_X_10_5_8_ComboUpdate
One of the "fixes" includes: - compatibility and reliability issues when joining AirPort networks.
After the installation, repair disk permissions.
Quit any open applications/programs. Launch Disk Utility. (Applications/Utilities) Select MacintoshHD in the panel on the left, select the FirstAid tab. Click: Repair Disk Permissions. When it's finished from the Menu Bar, Quit Disk Utility and restart your Mac. If you see a long list of "messages" in the permissions window, it's ok. That can be ignored. As long as you see, "Permissions Repair Complete" when it's finished... you're done. Quit Disk Utility and restart your Mac.

OSX 10.6.8 and Internet Sharing to Ethernet

I am trying to set up Internet Sharing so that I can connect my old MacBook Pro running 10.6.8 via ethernet to another device - I'm trying with xbox360 and Sony Blu Ray (BPD-S185) (for diversity of devices - I used to have it working on my xbox, but really want it working with the blu ray player but the network status feedback is better for problem solving on the xbox!).
I have my MBP connected to my home network over Airport which has the following details:
- IP: 192.168.1.5
- Router IP: 192.168.1.1
I have then enabled Internet Sharing through System Preferences to share my Airport connection to my Ethernet connection.
I have the following Ethernet settings:
- Configure IPv4: Using DHCP with manual address
- (Ethernet) IP address: 192.168.2.1
- Subnet Mask: (blank - not user accessable, changes to 255.255.255.0 when xbox turned on)
- Router: (blank - not user accessable)
- DNS Server: 192.168.1.1
- Search Domains: (left blank)
On the xbox I've set the network settings to:
- IP: 192.168.2.2
- Subnet: 255.255.255.0
- Gateway: 192.168.2.1
- Primary DNS: 192.168.1.1
- Secondary DNS: 192.168.2.1
When I then select 'Test my Xbox Live Connection' it takes a while, the Network status shows 'Connected', however The Internet Failed. I am informed that the 'Test Failed' and 'more information' tells me I have an 'Internet Error' with the following Status codes:
W: 0000-000B
X: 0000-000D
Y: 0000-0000
Z: 0000-0000
ID0004-000
L: 0015-10F1
Q: 8007-0435
T: Wired
A: 192.168.2.2/255.255.255.0
G: 192.168.2.1
D: 192.168.1.1/192.168.2.1
So, it looks as though the problem lies with the MBP and internet sharing on OSX. I have extra suspicions that this is the problem, as connecting my Blu Ray player to my MBP via ethernet I also get a successful connection to the network, but no internet access.
Pleeeeease can someone help?!?! This is driving me nuts - a couple of years ago I had internet sharing working to let my xbox connect to the internet, so what's happened in the last few years to mean this won't work?

If you want to back it up there, use the Disk Utility to create a disk image of it.
If you want to import its contents to iMovie, iTunes, or elsewhere, use MPEG Streamclip and Apple's MPEG-2 playback component to convert the VOB files on it to a different format.

HT1433 Hi, my internet sharing was working perfectly in 10.6.8, sharing my vpn connection to my apple tv with no problems. I then upgraded to 10.7 etc and internet sharing stopped. I have since reverted my computer back to 10.6.8 but no luck still, though

Just bought a 3TB Time Capsule for a small office. Will have 4 users with MacBooks. What would ne the best setup for time machine individual backups and internet sharing in a secure way?

Just bought a 3TB Time Capsule for a small office. Will have 4 users with MacBooks. What would ne the best setup for time machine individual backups and internet sharing in a secure way?

Set up each Mac for Time Machine backups in the normal way. Time Machine will keep each backup separate on the Time Capsule, so users will only be able to see the backups of their own Mac.
Yes....there are convoluted workarounds that might allow one user to see the backups of another.....IF...they know the administrator password of the "other" Mac.
As far as Internet sharing, all users will have access to the Internet if they have a wired or wireless connection. If a Mac connects using wireless, it is possible to limit the time that they are allowed to connect to the network.
For example, you might limit the ability to connect to the wireless from say each Weekday from 8 AM to 6 PM.
With a wired Ethernet connection, you cannot limit access times to the Internet.

Computer - computer network and internet sharing

I apologise if this has been discussed elsewhere - please point me to any useful links.
I have a G4 iMac and iBook (running 10.4.6) both with airport extreme cards installed. I would like to use a computer to computer connection for file / printer sharign and most importantly to share the ethernet connection to the internet running through my iMac.
I would be extremely grateful if someone could point out how to do this and incorporate a practicable level of security (I don't want any of the hundreds of people in adjacent flats downloading lord knows what through my connection).
Having accomplished this, I then need to be able to create a similar connection when required so that when required I can share the internet connection from the iMac with our PC laptop running Windows XP service pack 2.
So, the simpler the better, instructions for creating a computer - computer network for internet and file sharing between two Macs and following that between the Mac with the internet connection and a Windows laptop.
Thank you very much in advance.
G4 iMac USB 2.0 / G4 iBook Mac OS X (10.4.6)

You don't need to setup up computer to computer connection if your using internet sharing. Once you start internet sharing then your 2 computers are connected togther.
I would be extremely grateful if someone could point out how to do this and incorporate a practicable level of security (I don't want any of the hundreds of people in adjacent flats downloading lord knows what through my connection).
The problem you have is that if you enable internet sharing on one of your macs to share its connection over airport then the only level of security you can enable is WEP encryption.
The problem with WEP encryption is that it offers no real security and can easily be cracked. WPA is the only security you should consider using and unfortunately OSX does not have WPA encryption functionality when using the built in internet sharing function.
Your best solution is to get a wireless router that has a SPI firewall an WPA encryption. Depending on what your current internet connection is and how it is provided would determine the best kind of router to get.

Created Network and Internet Sharing Problems

Hello,
I created network with WEP password. I proceeded to turn on internet sharing.
All works great until the iMac goes to sleep.
Once it comes back on the network I created is missing and I have create it all over again.
The internet connection is through ethernet staring into the iMac.
Is there a way to get the iMac to stop forgetting the created network and leave the internet connection on? Even when it's sleeping.
Thanks in advance.

Hi there,
Is there a reason why you chose WEP? I ask because WEP is an encryption technology that has been cracked so if possible I"d suggest you use WPA or WPA2 encryption instead. Am I correct to assume you don't have a router and all the other computers connect to the internet through the imac? If you don't have a router I'd suggest you buy one, they are not much money and provide excellent protecton from the internet. A router will protect all the computers on your network behind its firewall and would no longer have to connect through the imac.
A couple of things to check:
Go to System Preferences>Network and highlight 'Wireless' on the left side. (Also, if you don't use Bluetooth or any other type of networking listed there delete them from the list leaving only Ethernet and Airport) Uncheck 'ask to join new networks'.
Then click on 'Advanced..' and under the Airport tab make sure only your network is listed in the 'Prefered Networks' window. Under that window check 'remember any network this computer has joined' and uncheck 'disconnect from wireless networks when logging out'.
That's the way I've got my computer set up and I've never lost a connection.

Bonjour Printing and Internet Sharing battle.

I use my MBP as a wireless router in my dorm room, so I have internet sharing on from ethernet to wifi. I also have a printer connected to it. My roommate uses my printer, so to make things a lot easier, I turned on printer sharing, and he downloaded Bonjour for his (pitiful) Windows computer. However, when he uses bonjour to print over the wireless network, internet sharing blows up and my iPod can connect to the wireless network, but is unable to connect to the internets. This is resolved by turning printer sharing off and restarting internet sharing. However that is a (comparatively) giant hassle and I would prefer my mac to work as perfectly as it should.
Help?

Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, then move these files to the Desktop.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
/Library/Preferences/SystemConfiguration/com.apple.nat.plist
/Users/YourUserName/Library/Preferences/com.apple.systempreferences.plist
/Library/Preferences/com.apple.sharing.firewall.plist
(Then Trash the original of this one, as "moving" it only copies it.)
Then reboot once more.
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.
EDIT: added a couple of things.

Yosemite and Internet Sharing

My internet sharing is not working since I upgraded to Yosemite. When I switch on sharing and try to share my ethernet internet connection via wifi my iPhone 5s is not able to even see the Wifi network that should have been created. I have tried switching the Firewall off but my phone does not even
This used to work perfectly when I was on Mavericks.

Hi,
If your sister is on 10.5.x there is a "known issue" with Internet Sharing if it is On (even if nothing is attached as it were) and iChat.
The upshot is in OS 10.5.x Internet Sharing has to be Off.
If it is On because of Parallels then the two VPNs that are also created need also turning Off in System Preferences > Network and Parallels told to gets it's Own IP from the Routing device (Which she of course does not have).
What happens is Internet Sharing invokes the AMc to be a router and issues IPs to the devices connected.
This is turn provide s route to the Internet.
Unfortunately in Leopard (10.5.x) iChat can see this route to the Internet even if it is a WiFi able Mobile phone.
iChat cannot resolve tow connection to the Internet.

REMOTE and "Internet Sharing"

Maybe this won't work at all with the existing REMOTE application, but maybe someone has a solution.
I have several Macs connected to the internet via a Netgear switch, all computers local IPs are 192.168.0... assigned via DHCP from the switch. Some of the computers connect to the switch via hard wired ethernet; others, via Airport Extreme or Express base stations. REMOTE sees all of the itunes libraries if it uses one of the base stations Wireless networks, since then then the iPhone gets a 19.2.168.0... address as well. (Note, my airports don't serve up DHCP address, the switch does)
But a couple of my computers are connected via hardwire ethernet to the switch, and have "internet sharing" enabled (firewall off, the switch does that job). if my iPhone connects using one of the "internets shared" computer, REMOTE will then only see the iTunes on that one computer. Probably because internet sharing serves up an IP like "10.0.2.x" and so it is on a different network.
I know that REMOTE only sees iTunes on the same network. So the question is, anyone know how to get "internet sharing" to serve up different address which I can specify? Or how to get REMOTE to just see "shared" libraries in an iTunes it does connect to?
Eddie O

I"m closing this. There is no solution, apparently.

Firewall blocks internet sharing

Hi all,
I know this has been covered before but I've never seen a solution that works for me. Maybe someone has time to talk me through it.
All I need to do is configure the OS X firewall so that internet sharing via ethernet isn't blocked by the firewall. Can I do this via the terminal? Which ports do I need to open? I need this to work so I can distribute builds across Xcode installations but I think internet sharing is all that is required for it to work.
Thanks,
Stephen

In the Sharing pane of System Preferences, click the Advanced button under the Firewall tab, enable firewall logging, and then try using those services on the other computer. When done, check the firewall log and look for the number after the : in the logged entries; this is a port number. Knowing the IP address of the other machine will help determine which entries were produced by it as opposed to ones which came from the Internet; this is visible in the Network pane of System Preferences.
