Internet Sharing Blocking MSN

I have a mac mini on my desk which is connected to internet with an ethernet cable, and I also have iBook G4. I use the airport on the mac mini and set up internet sharing to get online with the iBook. I can surf on websites, such as I am writing this on my laptop, but I cannot access for instance MSN, and some other services from here, but I can get to them on the mac mini. Is internet sharing blocking access to other ports or what's going on?
iBook G4 Mac OS X (10.4.2)

Yes, I managed to connect if I turn of the firewall. There are no messages in console.log. Obviously the firewall is blocking everything but http traffic through the mac mini.

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.

Lumia 920 - internet sharing doesn't work: Connect...

Hello all,
I'm experiencing a serious problem with the lumia 920. It seems impossible to share my internet connection. Something I normally use for several hours a day. If this problem can't be fixed soon, ill be forced to swithc back to iphone or htc.
Problem description:
When turning "internet sharing" on:
Connection not shared - There is no cellular data connection to share right now. Check your cellular settings and signal, and try again.
Important remarks
Belgium - cellular provider is Mobistar
I can browse, sync email, etc over the provider's network ans send and receive MMS.
Provider does not block internet sharing. Have always used this.
OS Version 8.0.10211.204
Firmware revision: 1232.5957.1308.0002
Access point :
Nokia Access Point version:3.4.1.7 - db 2.0.0.100 - lib 1.2.0.7
The default access point provided in the Nokia Access Point app does not work: can't even browse.
Using a manually added APN:
Data type (default / LTE) tried both. Everything keeps working - except internet sharing...
APN pro.web.be (for professional subscribers)
MMS APN mms.be
MMSC address: https://mmsc.mobistar.be
What have i tried to remedy the situatiuon?
updated the Nokia Access Point app
changed language to spanisch using OTA update (silly, but read on a forum this might help)
soft reset of the phone (often!)
deleted the manually created access point
Hard reset of my phone
I'm interested, of course, in any tips to solve this serieus bug / issue / problem.
(my best guess is that Nokia tries to help their customers with the Access point app, but fails to do so).
Please, if any of you experience the same problem please respond to this post so we can get an idea about how big of a problem this is.

Hi,
I had the same problem. But I let it go after weeks of corresponding with Mobistar.
Yesterday I went to a Mobistar shop, the guy tried lots of thing I already tried (different apn's, ...).
Then he told me the it's a problem with business clients. They have to use the apn web.pro.be, where internet sharing doesn't work (he doesn't know why).
But, that if I call to Mobistar and ask to activate apn mworld.be on my telephone number, it should work.
Today I called Mobistar Business (you can find the helpdesk number on your invoices), asked to activate mworld.be to have internet sharing access on a windows phone.
Half an hour later, using mworld.be as apn i have internet access, and I can share my internet connection.
regards,
Stijn

Internet Sharing & Home Sharing

I have a MacBook Pro sharing hotel Ethernet over wifi. Meaning the machine is serving as a wifi router because the wifi here is completely choked by all the people using it....but Ethernet is blazing fast..so I'm making my own wifi.
One interesting thing, Apple provides Internet Sharing which is awesome.....but it's NOT serving DNS. My iPhone, iPad, Apple TV all connect but can't see the internet without me specifying a DNS server on each client. That really stinks, but isn't the reason for my post.
The post is mainly because iTunes Home Sharing (Airplay) doesn't work over Internet Sharing. WHY?
If my MBPro and Apple TV are connected to hotel wifi airplay won't work, but if I connect an Ethernet cable from the MBPro to the AppleTV, BAM home sharing works.
So, in theory shouldn't Internet sharing with the firewall turned off work with AirPlay? Why is it blocked? How do I unblock it?

Welcome to the Apple Community.
Intermittent problems are often a result of interference. Interference can be caused by other networks in the neighbourhood or from household electrical items.
You can download and install iStumbler (NetStumbler for windows users) to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.
Refer to your router manual for instructions on changing your wifi channel or adjusting your multicast rate.
There are other types of problems that can affect networks, but this is by far the most common, hence worth mentioning first. Networks that have inherent issues can be seen to work differently with different versions of the same software. You might also try moving the Apple TV away from other electrical equipment.
The following article(s) may help you.

Internet Sharing Stopped Working

At home, I have a G5 dual 2Ghz as my primary computer and a G4 450MHz that I use mostly as a file archive. I was running OS X 10.4.10 on both machines. My internet connection device (an AirCard from Sierra Wireless)is hooked up via USB to my G5. I set up internet sharing on the G5 so that I could share the connection with my G4. At different times I used ethernet (T100) and Firewire 400 to successfully connect the two machines and share the internet connection. It worked great, especially the Firewire because of the higher speed.
The internet sharing just stopped working and I'm trying to figure out why. The actual hardware Ethernet or Firewire connections are fine. I still have a good internet connection on the G5. The local connection between the machines is also still good and I can transfer files between the machines at expected speeds across either connection. On the G4, IP addresses are assigned to both the Ethernet and Firewire ports via DHCP and they seem valid. The G4 "thinks" it's connected to the Internet, but I can't pull up a web site using either Safari or Firefox.
I had both the ethernet and Firewire hooked up at the same time. Suspecting some sort of conflict, I tried them individually (i.e. disconnecting the other), but had no luck. The closest I came was when I had just the ethernet connected. I managed to pull up a bit of the Apple site, but it didn't finished loading. It was like only a few packets got through. I tried other URL's and got about the same results. I suspected maybe a firewall was blocking something, so I temporarily turned the firewalls off on both machines. No luck.
I checked my Internet Sharing setup on the G5 and verified it had not been changed. Internet sharing is running and is set up to support both Ethernet and Built-In Firewire. I also checked network setups on the G4 and that seemed okay too. I'm kind of a fanatic about documenting my setups, so I have a good record of what worked at one time.
The only think that's changed (that I'm aware of) is an update from OS X 10.4.10 to 10.4.11 on both machines. I suppose something at my ISP could have changed, but they sent no notices if that's the case.
Any suggestions would be greatly appreciated.

Thanks to those that replied. Sometime around 2AM last night, I couldn't sleep and started working on the problem again. I finally found out what was causing this Internet problem.
The AirCard requires a program called Sierra Watcher (SW) to connect to the internet. A few days before I noticed the problem, SW got corrupted somehow. I ran the SW installer to remove it, then do a fresh install. What I didn't realize was that some portion of the old corrupt installation remained, even though I had used the Uninstall feature of the SW installer to remove the old version.
While checking everything I could think of, I went into the Network panel under System Preferences and had it show the Network Port Configuration. There was a listing there for AirCard as there should be, but there was also a second listing for AirCard, which was grayed-out. I deleted the grayed-out version and hit Apply Now. I then shut both computers down (not just a reboot). When I brought them back up, everything worked! It appears that the G5 had been sharing the old corrupt "connection" instead of the new good one.

Firewall, Internet Sharing, and Leopard

Hi guys,
Here is my scenario: I use my Macbook to connect to a public wifi network in my apartment complex. I use my Macbook for internet sharing (wifi to ethernet) and have a Win!@#s machine which I use for gaming hooked up to the ethernet port. In Tiger, I was allowed to let the game (World of Warcraft) through the firewall by adding the tcp ports it used. But in Leopard I am not given the option to enable certain ports, only applications. The problem is, the application actually runs on the Windows machine, so I can't just select it.
I've been reading a bit and it appears Apple did away with the port filter method and has adopted this new application only method. I find it frustrating and the developers should have known better than to disable this feature. It has severely limited the security in the operating system and has cast away power users like myself.
Is there anyway to work around this issue? Either with 3rd party software or some other way?
Message was edited by: Frank Cabrera

I agree, Apple really blew it by trying to re-invent the firewall.
Not having the ability to open or block traffic by port and IP address was a terrible idea.
Limiting it to Applications only makes the firewall almost useless.
I would like this idea if I was also allowed to choose for myself.
This is a technological step backwards!
Many many people feel the same way and some are now relying on the still built in ipfw which is a commonly used and quite robust firewall. Unfortunately it is very difficult to configure unless you really know what you are doing. I am sure this was one of the primary reasons why Apple made this decision.
Search around this forum for ipfw and you will find a bunch of info. Just beware it is not exactly user friendly even with some nice GUI apps that help you configure it.
Send feedback to Apple about this or it will never get fixed.

Internet Sharing not providing a client an IP

I have turned on Internet Sharing on a 10.4.7 machine connected to the internet, and the other 10.4.7 machine is happily joining the wireless network created by the sharing machine. However, the client machine is not receiving an IP address from the connection sharing machine. Is there a bug here? Documentation does not describe that I need to set up the IP manually?

I found that the OSX firewall blocks necessary traffic if UDP blocking is turned on. I fixed the problem while leaving the firewall intact by making a rule to pass port 68 UDP traffic. After this, and with the firewall fully enabled, My client machine received an IP address within a few seconds of connecting.
Apple Support please put this port information into the support documents describing how to enable Internet Sharing.

UTorrent, Internet Sharing and Port Forwarding: Horrid Trifecta

Every good question has a couple of miles of back story, so here it comes:
I bought a Windows PC recently, and one of the first programs I downloaded was uTorrent. I have an iBook G4 running 10.4.8, but I have no wireless router, so I thought I would use internet sharing to get my new laptop off the ground. Everything connects great, internet sharing is wonderful on the web, but then I use uTorrent and notice that I'm uploading at nearly 3 times the speed I'm downloading, even when I only have 12kb of a file. I then notice the small icon at the bottom of the application that looks like a warning flag that my computer is confused, and I figure out that the problem is my new laptop has no ears, or rather, no listening port through which uTorrent can increase the speed of my DOWNloads. Further searching reveals that the traffic on the appropriate port is not getting through, hence I try to figure out how to manipulate internet sharing into forwarding the appropriate port range. I found Brickhouse, or as it is now known, Flying Buttress, but the program is remarkably confusing (to be perfectly honest, I'm not that bright). I cannot get FB to forward the port, no matter how hard I tried (every time I clicked Start IP Sharing, the it wouldn't work). So I can't use FB. I thought I would be clever and create a network on my Windows PC and share it with my iBook, but apparently my iBook refuses to share the Windows internet.
So now I am stuck trying to figure out how to get this Windows PC to receive traffic on TCP/UDP ports 10000-65535 through my Mac. To be honest, I really thought that the Mac would easily be able to forward the ports (is this in store for Leopard?), and I was a little disappointed the whole thing was so frustrating, but then I tried to setup an ad-hoc network on the Windows PC and realized that my Mac is still FAR easier to use, despite is insufficiencies.
So, long story short, I need help forwarding ports through internet sharing. If you can help me use FB, that's great, but to be honest, I would like a cleaner solution if possible. So my question is: How do I get my Mac to share port traffic with Windows if it is running internet sharing?
iBook G4 Mac OS X (10.4.8) Other Computer: Windows XP, other specs available on request

I was hoping more for a permanent solution that doesn't cost $100. Did I mention I'm in China? That program seems great and all, but I have the same technical difficulties I've had with FB. I can get the thing running and still have an internet connection on my machine, however, the port mapping or port forwarding or whatever you wish to call it doesn't actually work. These programs make it very difficult to understand what's going on; I checked the IP Address on my windows machine and used it as the actual address for the port I wanted to forward, I applied the settings and absolutely nothing changed on the windows machine. I went to portforward.com to check if the port was forwarded properly and still no response. This will sound stupid, but when I hook up the windows machine to the router through ethernet, it works perfectly, no forwarding required, so it is essentially my mac that is blocking or absorbing the intended traffic, but if I hook up the windows machine to the router, I have no internet for my Mac (I'm not sure if that's a problem with my Mac or with ICS). Can you explain to me how to use this program to forward ONE port, and ONLY forward one port (or a range of ports would be even better) without all of its inane firewalling that blocks all the internet traffic? Or am I just hopeless on this issue?

TC as a brigdge to extend internet sharing from Imac

Hello, can somebody give me a hand on a proper config for time capsule + Imac.
My setup is: 3G Huawei modem/router - wi-fi (g) network - Imac Airport- internet sharing (airport to ethernet) - ethernet cable to TC WAN port (TC in a bridge mode) - time capsule wi-fi (n) network.
All seems to be functioning well, and I can access second (n) network from Ipad, Iphone, Apple TV2 etc.
The final goal of this setup is to block with MAC filter on Huawei router I-net access for Apple TV while keeping an access for Apple TV to my libpary (photo/music) on Imac. The reason to do so is very simple - I have very limited data plan/speed from internet provider and I don't need neither youtube or anything from internet to hungry Apple TV (automaticaly eating lot's of data even refreshing covers etc and there is no way to turn it off even with parential control) I've puted MAC address in Huawei filter but Apple TV still accessing I-net. Looks like it using TC router and I can't turn it off to force using Huawei router. Any thought? Thank you

Well, if there's anyone else with this problem, I have an update:
1. After some reboots, for reasons unknown, the G5 started to connect.
2. However, it would only connect to an unencrypted network from the iMac. When I tried to change to an encrypted network, it wouldn't connect. Nor would it work when I switched back to an unencrypted one!
3. I then tried the following, from another site:
Start Internet Sharing if it's not already running.
In Terminal, type cp /etc/bootpd.plist /tmp/bootpd.plist
Stop Internet Sharing.
Open "open -e /tmp/bootpd.plist" for editing using TextEdit or whatever.
Locate this section of the file, near the end:
<key>replythresholdseconds</key>
<integer>4</integer>
Change the value 4 to 0.
In Terminal, type sudo cp /tmp/bootpd.plist /etc
Start Internet Sharing.
If you want to, check that your change to /etc/bootpd.plist hasn't been reverted.
Source - Following 10.5 Steps
http://www.macosxhints.com/article.p...ery=xbox%2B360
4. It worked. Now the G5 will connect to an encrypted Internet Sharing network from the iMac. Not only that, my iPad, which previously would not connect to an encrypted network from the iMac, will do so as well.
Hope no one else is as frustrated as I was!

Internet Sharing: Palm Device can't find Internet via USB to Imac G5

None of the internet-using applications on my Palm Tungsten E handheld can find the internet, via a USB connection from the Palm to my Imac G5 and its high speed internet connection.
I have 3rd party software (The Missing Sync 5 from Mark/Space) that is supposed to enable a USB-connected Palm device to share an OS X Mac's internet connection. But I'm not getting beyond the Mac and I think either something on the Imac or perhaps my Linksys router is blocking internet communication to and from the Palm device.
Despite turning off the Mac's firewall and enabling internet sharing in the OS X prefs panes, neither my Palm's web browser nor its mail program can get through to the internet and all I get are communications errors.
I would greatly appreciate suggestions as to what to try next as I have done just about everything I can think of to try to get this Palm to access the internet via the Mac
IMAC G5 Mac OS X (10.4.5) 750 Mb RAM

Hello Adrian - thank you for your suggestions. The USB-connected PALM does NOT show up in The Imac's "Network Ports" - - and the only thing I could add, as a port, that was not already there, was something called "6 to 4" -whatever that is.
The Palm is supposed to be able to get its internet page requests out onto my router and DSL line via the Mac's ethernet port when: A) this Palm is connected to the Mac via USB and B) when the Internet sharing feature is enabled in a software app called - The Missing Sync, which it is, and when C) Internet Sharing is turned on in the Mac 'Sharing' pref. All these conditions are true, but sadly none of the internet apps on the Palm can find the internet .
I suspect a DNS issue - even though my router of course knows the DNS addresses of my ISP.
I should think that the PALM and the host Mac would have the same IP address - namely the one assigned via DHCP by my router when the Mac boots up.
Very frustrating....
I know nothing about Palms but I'll give it a
shot...
You say "Despite turning off the Mac's firewall and
enabling internet sharing in the OS X prefs panes",
are you seeing a USB option in the window? If so
select it.
If not try going to System Preferences>Network>Show:
Network Port Configurations. (This with the Palm
plugged in via USB).
Is it in that window? If it is tick it and go back to
internet sharing and select it in that window. (It
should have now appeared).
If it's not in System Preferences>Network>Show:
Network Port Configurations; select 'New', and click
'Port'. Does it appear in the drop-down list there?
If it does, select it, name it and click OK. (Note:
USB isn't a 'normal' option here but maybe your
Missing Sync will have added it..?)
That will take you back to the main Network Port
Config window where you tick it if it isn't already.
Then go back to Sharing>Internet to see if is
available there. If is is, tick it.
If it isn't, don't know. Sorry.
Have fun!

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.

VPN Internet Sharing?

I'm thinking about getting OS X Server, and I was just wondering if it's possible to use the VPN function of the OS X Server to share the Internet connection on the server computer? For example if I have my iMac connected to the Internet through a VPN (I live in China), and then have another VPN which connects to my MacBook Pro, would I be able to use the VPN connection between my iMac and my MacBook Pro to visit the Internet through the Internet VPN connection on my iMac? I know this sounds a little abstract and weird but it would help since the VPN I bought that connects to the US only works on one computer at a time so it would be nice if I can use my own VPN to group all my computers under one connection and be able to visit YouTube (blocked in China if you didn't know) on all of them at once.

Oh I know about the Internet sharing functionality in System Preferences, I'm just asking because I might buy OS X Server anyways for school work and having my personal site, email server etc. I've tried to activate it using Bluetooth but for some reason it wouldn't connect to my MacBook Pro, what I'm trying to do now is this: I have a Time Capsule and when I'm at home both my iMac and my MacBook Pro are connected to it, so they are on the same LAN network. Basically what I'm trying to explore with is exporting that VPN connection to SF on my iMac to my MacBook Pro via the VPN on the LAN network on my Time Capsule. So the entire thing would just run on the Wifi interface but instead of sharing my network by inputing the Internet connection in one end and outputting it to another computer on another interfece, I'm trying to see if that connection would work over the LAN network. Thanks anyways.

Connecting my Powerbook to my iMac for internet sharing via airport

Thanks in advance for any help.
I have given up trying to get an answer to my Airport problem and NTL Virgin.
I now have my iMac connected to web via ethernet all okay for a week now so it can't be my connection that was the problem.
I need to connect my PowerBook to the internet now at the same time. I would obviously like to do this using wireless technology. I was hoping to web share my iMacs connection via the airport cards on both macs but seem to be struggling.
I can set up a new network on the iMac and get the PowerBook to see it but it won't connect to the internet.
Any advice would be great thanks

Open DNS and internet sharing

I am seeing strange behavior, and wondering if anyone has a thought about what is going on.
I am at a hotel with fast internet service over ethernet, but, for whatever reason, DNS seems very slow if I use DHCP to connect (timeouts of 5-10 secs to get to a new site). If I switch to DHCP with fixed DNS, and use the Open DNS servers (208.67.222.222, 208.67.220.220) the latency issues go away.
The interesting thing is that I am sharing the internet connection over Airport to my wife's computer (she connecting thru DHCP). If I use a fixed DNS for MY computer, then her computer cannot connect thru internet sharing. But if I use the (slow) DHCP connection, then she can connect through mine. I have not tried setting up her computer with a fixed DNS, as she really doesn't like me to change settings on her computer
Is this a known limitation of internet sharing, or is there something I should know?
TIA

In more detail, if my ethernet (the computer that is doing the sharing), is set up with Configure: Using DHCP, and DNS Server: 208.67.222.222, 208.67.220.220 (in Network Panel for Ethernet), then the computer connecting thru Internet Sharing in Sharing Panel is not able to access some or all resources thru http (ie, pages fail to load, or do not fully load).
However, if I clear the DNS Server part in the Network Panel, thereby using the the DNS Servers supplied by the hotel, then my computer's connection to the internet is slower, with long waits (presumably due to a slow DNS server), but computers accessing the internet via Airport thru my shared connection are able to browse the internet successfully.
I suspect that when I have a fixed DNS server in my computer, that fact is not broadcast to computers using the shared connection. But I am not an expert in TCP/IP, and may well be confused about how DHCP, DNS, and Apple's Internet Sharing work together.
Thanks for any ideas you have
A
