Forwarding Ports While Using Internet Sharing

I'm trying to get StarCraft working (being able to host games) on my MacBook Pro which is connected to the internet through an iMac G5 which has Internet Sharing turned on and is connected directly to the cable modem. I found some directions online involving using natd on the iMac to forward the ports manually. I have set natd to run on startup with a "-f natd.conf" flag, and my natd.conf has these lines:
redirect_port tcp 10.0.2.2:6112-6119 6112-6119
redirect_port udp 10.0.2.2:6112-6119 6112-6119
10.0.2.2 is the IP address that the iMac has given my MacBook as stated in my Networking preference pane. However, hosting games in StarCraft still does not work and according to this site my port 6112 is still "closed".
Any ideas?

Firewalls...harumph.
Cause more problems than they solve...not really
Two firewalls (mac's and this intego thingie) will cause more problems than running two antivirus programs on a PC.
Folks need to come up with really good reasons to use more "firewall power" than mac's excellent firewall.
Anyway, glad you found it!

    Powerline adapters use your home powerlines (mains a/c) to connect your devices via ethernet to your modem, they're easy to set up and the they TOTALLY fixed my ATV problem, the problem seems to be with the wireless. I've been trawling through apple discussions, and did found a workaround to my problem https://discussions.apple.com/thread/4222883?start=0&tstart=0
    but its just a workaround :/

  • How can I use Internet Sharing with Firewall on ?

    Hi,
    My PowerMac G5 is connected to the internet via Ethernet. I share the connection to a Powerboog via Airport using internet sharing. Everything is working fine except when I turn the Firewall on. After reading http://docs.info.apple.com/article.html?artnum=107653 I tried opening port 443 but it still does'nt work. I'd like to be able to use internet sharing with the firewall on. Anyone can help me ? Thanks!

    Hmmm, how curious... I never had to do that in 10.4.7 or 10.4.8... the only ones I ever tried Internet Sharing with.
    I'm wondering if turning the Firewall on after the Internet sharing is what's doing it? Just for kicks you might try turning off Internet Sharing, then Firewall on, then turn on Internet Sharing.
    If that doesn't work, then I'd personally try trashing...
    /Library/Preferences/com.apple.sharing.firewall.plist
    Then reboot and try the Firewall again.

  • How to use internet sharing and airtunes?

    Question? how to use internet sharing and airtunes?
    OK I have following working separate situations.
    1. I can share my internet connection : is a router to ethernet cable into mac. Then over airport built in to my iMac ....... to other wireless computers, iphone etc...works fine.
    2. the I have a air port express that is only used for air tunes. I guess i had create a separate network for that. can select that in iTunes. Works.
    problem is can not use both at the same time!
    OK so Now I would like to combine the two; share the ethernet over airport on mac and send music to air port express....
    the main reason for this is cause I now have an iPhone and want to use the internet and the remote app to control iTunes from all over the house.
    I have not the first idea where to start.
    Any hints or tips will be greatly appreciated.

    The airport express is a router. And, only one router can be used to obtain an IP address. So in your airport express configuration set it so it does not obtain an IP address.

  • Can I use internet sharing to give internet to my Apple TV through my Macbook and use Airplay on the same computer at the same time?

    So I am using internet sharing from my Macbook to my Apple TV. The router providing internet to my Macbook has an ip address that looks like 192.168.0.x. Since the internet sharing feature assigns an ip address that looks like 192.168.2.x to my Apple TV, the Macbook is unable to see the Apple TV ("different" networks). Is there a way around this so I can share internet and still be able to use Airplay between the two?
    BTW I am using a Macbook Pro Retina 15'' (late 2013) on Mavericks 10.9.1 and Apple TV 3.
    Thanks.

    Why are you tyring to spilt your connection though the MBP?  Why don't you just connect them both to the router as they are meant to be setup?

  • Slow access to local WebServer using Internet Sharing

    Hi,
    I have a MacPro with a WLAN. Sometimes I use internet sharing to access the internet with my iPhone. When using the "Browse the Web" feature of Goodreader to access some files on my MacPro it took very long until I get a directory listing on the iPad (only a dew files and folder). The other Way aroung (using the Goodreader intergrate WebServer an access this from my desktop is quite fast.
    The desktop has an IP Number 192.168.1.2 the iPad someting with 10.xx.xx.xx. Putting the into the same ip number schema (using a wieeless router) works fine in both directions.
    Any idea why the server is so slow?

    Hi,
    I don't know if any of you came up with an answer to this problem, because I have the exact same problem.
    I use version 5.0.01.0600 of the VPN Client. Windows Explorer hangs for a couple of seconds and then works fine for a couple of seconds and then hangs for a couple of seconds, etc. When logged on in Windows XP with a user with administrator rights this problem doesn't occur. Only when logged on with a Restricted user (Users Group) does this problem occur.
    Hoping you can help,

  • Not able to use internet sharing on my iMac 8.1 using Mac OS X 10.6.8

    Im not able to use internet sharing on my iMac 8.1 using Mac OS X 10.6.8, I tried internet sharing with OS Lion and it works fine. Has anybody else experience this problem and  what was the solutions.

    If your OS is OS X 10.4.11 then you should be able to install iTunes 8.1 which according to the iTunes page requires 10.4.10 or later (which is a lower version than yours). It also requires QuickTime 7.5.5 so check your version of QuickTime. Version 10.4 is Tiger by the way. Leopard is 10.5 and Panther was 10.3.
    Make sure that your OS is at the version you think it is. Connect your MacBook to the internet and from your desktop go to the Apple symbol on the Finder bar at the top of your screen. Choose "About This Mac" and check your OS version. Also from the same menu choose Software Update and see if you are offered any updates for your computer. If it does offer an OS X update, install it and anything else in the list then run software update again to see if any more components are offered for the new version.

  • Using Internet Sharing on Macbook Pro 17" (intel) with the iPhone

    Hi,
    i like to use Internet Sharing on my Macbook Pro 17" (intel) with OS X Leopard.
    Enabling Internet Sharing on Leopard works just fine. I share my Ethernet Connection with the Airport.
    I can connect to the Airport sharing the connection with multiple devices.
    It does however not work with the iPhone.
    The phone can see the network. It even connects and gets its lease (IP Adress / etc)...
    I did open a terminal and did ping the iphone. Doing that i disconnected the iphone from the wifi network and connected again. I found out that immediately after connecting the connection is working (ping reply) for about 2 or 3 seconds and then there is no reply... Sometimes it is working... but 99% of the connections dont work... (working for 2 seconds and then no reply)
    This is only with the Internet Sharing on the Macbook Pro (intel) in combination with the iPhone. I did not have any other wifi problems with the iPhone or with Internet Sharing on my Macbook Pro.

    Hi,
    thank you for your posts!
    Nathan C: Did you notice this issue occurring when you were using Mac OS X 10.4?
    Yes! I did not get it to work with Tiger also.
    mucmac: just solved the issue by setting the channel for airport under Airport Options in sys prefs>sharing>internet sharing from Automatic to a specific channel
    lazarus: Doesn't work for me.
    and not for me
    Richard Cartledge: Maybe it is a Leopard issue?
    I think its a Macbook Pro / iPhone issue. Because other clients work well also the iPhone works on a Powerbook using Internet-Sharing.
    Aaron@SODE: No luck for me! Tried every Channel and every MacBook Pro and MacBook in the company. The only Internet Sharing working is a PowerBook G4 running Leopard 10.5.1. iPhone works with the Powerbook without any problem.
    The same applies to me! I really think it is a problem with the iPhone / Macbook Pro.
    mucmac: what model of macbook Pro do you use? I cant get it to work on a Macbook Pro 17"

  • File Sharing between Windows PC and MacBook Pro using Internet Sharing

    I have a MacBook Pro and a Dell Latitude D820 running Windows XP SP2 and I want to connect both using any of these two options. I do not have a wireless router and I use Sprint 3G data card to access internet.
    1) I access the internet using a EVDO data card on my MAC and use Internet sharing to access the internet on my Dell laptop. How do I access the files on my PC from my MAC?
    2) I can have two EVDO data cards to access the MAC and PC independently. How can I setup file sharing between Windows laptop and MAC?

  • Using internet sharing in other countries

    Hello,
    I've bought a HTC 8X unlocked cellphone from Verizon and moved to Brazil since them.
    How can I use internet sharing here? The cellphone says it's not allowed, although my internet plan here does allow me to do that.
    It seems besides being an unlocked phone, Verizon is still locking the internet sharing option.
    Any help is really appreciated,
    Cheers,
    André

    The answer is not really, but sort of.
    If you have a US mailing address, a credit card that bills to that address, and a US Social Security Number, you can purchase and activate an iPhone in the US. The problem is that the phone is locked to AT&T as the mobile provider, so when you go to those countries, you will be roaming, which is expensive for calls and outlandishly expensive for data. You will not be able to inset a SIM card from a local mobile provider; it will not work. Also, AT&T may cancel you for roaming too much.
    A fair number of people outside the US (and inside as well) appear to have purchased iPhones and hacked them so that they can be used as an iPod and WiFi device but not as a phone. I think those in other countries are hoping that someday they will be able to use the phone features in their country, though it is not certain that will ever be the case.

  • Help with using internet sharing on my MacBook Pro with an old mac mini

    I have an old mini osx 10.4.11 with no wifi.  My much newer MacBookPro osx10.6.7 can't seem to share it's internet connection between it and the mini via ethernet cable.  I'm using the MacBook airport to connect to my SMC router.
    The DHCP on the mini has an IP, and it seems correct.  But, I can't get a browser to connect.  Can someone suggest a way to troubleshoot?

    That is the more difficult of the forms of Internet sharing possible on a Mac. Of course the easiest thing to do is put out US$100 and just get an AirPort Express and connect the mini to the Express' Ethernet port. The mini would have the fastest connection that your router puts out with none of the hassles of connecting and disconnecting when you want to leave with the MacBook.
    Read over my last comment in this thread for the configuration of wi-fi to Ethernet. Just substitute the mini for the XBox.

  • Trying to use Internet Sharing, but it keeps turning off.

    Hello all,
    Alright, so I'm in a dorm room that connects to a wired ethernet network using 802.1X authentication. My MBP does that just fine. The only problem is getting my Xbox 360 online. The Xbox does not support 802.1X authentication, and the only thing the school said I could do was use a second ethernet port on my computer and Windows ICS. Of course, I know that Apple also has an ICS type thing of it's own through Internet Sharing.
    I'm using the Linksys USB200M USB-Ethernet adapter as my second ethernet port. I've tried connecting to the internet using it and it works great.
    The only problem I'm getting is keeping the Internet Sharing on. Everytime I turn it on, Share FROM Built-In Ethernet, and check mark the Ethernet Adapter (en3), the thing won't stay on. I'll change them menu, go back, and it's turned off.
    I've searched for an answer, which required me to delete the com.apple.sharing.firewall.plist out of Library/Preferences. This DID NOT WORK.
    I would really hate to have to boot into Windows Vista to use my Xbox 360, as I have been successful doing that. I like to work in OS X more than Vista.
    Thanks for your time,
    Jake

    Repair Permissions if you haven't yet, then the other file that can affect that is...
    /Library/Preferences/SystemConfiguration/preferences.plist
    But it also holds all your Network info, so...
    Reboot after either or both, depending what you decide.

  • How do I use internet sharing from my MacBook Pro (static IP, only one DNS server) to my iPod Touch?

    Hey,
       I'm connecting to the net using an Ethernet cable to my MacBook with the following network settings.
    IP Address: 192.168.y.{0-250}
    Subnet Mask: 255.255.255.0
    Router: 192.168.y.x (where 'y' is the same number as in the IP address)
    DNS Server: 192.168.99.3
    Apologies if I'm being unclear; not sure how much information it's OK to share publicly.
       I then turn on Airport and Internet Sharing, and look for my wireless network with my 4th generation iPod Touch. However, the network appears erratically. I sometimes have to wait for a minute or two and keep refreshing before it appears on my iTouch. When I try to connect it just says 'Failed to connect to the network'.
       I've followed all the steps in this article with several variations to no avail.
    http://lightyearsoftware.com/2010/06/how-to-set-up-internet-sharing-on-mac-os-x/
       Can anyone suggest a solution? Any help would be greatly appreciated. I've been banging my head against this for days.

    On the advice of a friend I installed and ran a program on my MacBook called 'IPSecuritas'. This has stopped my wireless network from appearing and disappearing, but I still can't connect. Would really appreciate some help with this.

  • ITunes isn't showing up in the Devices list when using Internet Sharing.

    Due to a neccessary relocation of my router, my two computers upstairs no longer have Internet Access (as neither have wireless capability). I am going to fix this issue soon by wiring in a new network to where the router is, but in the mean time I've simply been using my PowerBook G4 (running Leopard) as a Wireless access point. I simply plugged my two computers (via a hub) into my PB and turned on Internet Sharing.
    Now, both of my computers (an iMac G3 running Tiger, and a Windows 7 computer) have Internet access fine. But neither of the two recognise my Apple TV now, which is connected to the router via WiFi. They both used to recognise the ATV and it would show up in devices fine, and the only thing that's changed now is the internet access is coming from the PB's sharing ability, since I did this both computer suddenly stopped seeing the ATV and I can no longer sync/connect. iTunes is up-to-date on all three computers (well except for the iMac which has an older version on it for obvious reasons).
    The PowerBook on the other hand, does still see the ATV in iTunes. So I can only assume that for some reason the PowerBook is stopping the Apple Tv from being seen by the other two computers. Is there anyway I can fix this? Until I sort out a new network to my router which will take many months at the moment due to my own time constraints, this is the only way my two computers can connect to the ATV.

    That's surprising Roger, because it was showing up in searches on iTunes and feedburner has a title that I inputted under that rss feed.  Is there another way for me to add a title that I am missing?  I have pasted the feedburner screen that I see when I login:

    You should not change "Original Feed" unless you move your original feed to a new domain or a new location on your existing server. Also, changing "Feed Address" will require you to update your feed subscribers with your new address; the previous feed address will no longer work.
