Port forwarding through Internet Sharing

Here's my setup:
- I have a Linksys router, I have that connected wirelessly to my macbook, I have that setup for Ethernet internet sharing to my desktop pc.
- I want to enable port forwarding so that I can access my PC through VNC.
- My macbooks ip address is within 192.168.1.x and my desktop's IP address from the macbook is within 192.168.2.x
- When I connect to my router and try to set up port forwarding I can only forward ports within the 192.168.1.x range.
- I've tried a bunch of garbage to get it set up, one main thing I've tried was to st my PC's ip address statically to something withing 192.168.1.x, but my default gateway address is 192.168.2.1 so I'm not even sure if thats possible.
- I really need some help with this, any would be very much appreciated.

Hi guys. My setup is pretty simple. I have a Terayon cable modem hooked to an iMac. Im doing internet sharing to everybody. I don't need an access point and don't wish to have to buy a new one when I have such a beautiful machine right.
So I want to do port forwarding using the internet share to connect an XBox360.
The ports i want to configure are detailed in www.portforward.com
Anyway I can't see how to do it but I know that for you guys this is all puppy chow. So i decided to give you guys the opportunity to be creative with this setup.

Port Forwarding and Internet Sharing

Hey all,
I have a wireless network set up through a Time Capsule. My iBook is connected to this network via Airport. In addition, I have a computer with no wireless connected to my laptop via Ethernet. I have my System Preferences set up to Share Internet with Built-In Ethernet. The problem is this. I want to use the second computer (which accesses the Internet fine) as a server. The Airport does not recognize the second computer as a Client, but does see the iBook. I believe I need to Forward Ports to the iBook (local IP: 10.0.1.5) and then forward them again with the iBook to the other computer which has the local IP 196.168.2.2.
Is my thinking right in this? How would I need to configure this to make it work as I've explained?
If I'm unclear I can clarify.
Thanks,
Daniel

Hi Daniel,
I think the problem is, is that the Internet Sharing isa pass through connection.
Try this, in Network>Show:>Network Port Configurations, duplicate the Airport interface, make sure the on used for internet is dragged to the top of the list, then Manually configure if need be, the second one to join the local Network.

Port forwarding within Internet Sharing

my xbox is connected to my macbook sharing the wireless internet, but i want to forward a port to my xbox. how do i do that? can't connect the xbox directly to the router.

How did you get the xbox to share the internet connection?? I can't seem to get it to work with my setup for some reason.
I've got a macbook connected through wireless. The xbox is plugged into the mac. the internet sharing is on. Web sharing is on. The Airport is set as the top priority port... Double checked all the firewall settings... The only thing I can think I haven't tried is a different type of cable... Do I need a cross-over? I'm totally stumped!

TS2972 How do you port forward for Home Sharing ?

I want to home share with my apple tv and it's not working, so i think i need to port forward for home sharing on my apple tv. But i dont know how to port forward :S

I use an application called port map. http://www.codingmonkeys.de/portmap/ Make sure you download the landlubbers version. When you open it add a port called minecraft with the port 25565

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!

Airport connection through Internet Sharing

Hi
I was wondering if I have a Powerbook G4 with an airport Extreme card installed and I have a Desktop G5 without airport, can I do Internet Sharing through my cable modem, so I can get online with my laptop wirelessly and without a router or does my G5 have to have an airport card installed as well?
thanks for the help

I believe Duane was alluding to the fact that you have more options when using a router: configurations, security, expandability, etc. than you would if you limited yourself to just Internet Sharing.
With your current situation, instead of getting a wireless card for the G5, you can get (for example) a Linksys WRT54G wireless router. This router also has a built in network switch so you can still connect your G5 using Ethernet cable.
Your network configuration would then be:
Cable Modem > (Ethernet cable) > [WAN] Linksys Router [LAN] > (Ethernet cable) > [Ethernet port] G5, AND
Linksys Router > (wireless) > wireless clients.
Later, if you still wanted, you can get the wireless card for the G5, and all of your computer can access the Internet wirelessly.
As far as dial-up, this particular router won't support Internet connectivity. Instead, the only one that I'm aware of would be the AirPort Extreme Base Station (AEBS). No, in this case, you would just use the built-in dial-up moden in your computer.

IPad 2 connection through internet sharing

This may be answered somewhere else on the discussions, but I would like some assistance in connecting an iPad 2 to the internet through an iMac that is connected through an Alltel wireless card. In the iMac, I've turned Internet Sharing on, and the airport is also on. What am I missing ? ? ? Or is it not possible ? ? ?

Jack:
I wrote this on an earlier thread and it seemed to help another user so give it a try. Bold type is specific to you. Ignore anything you already know. I'm not sure if you can share the connection from a wireless connection (you CAN share from ethernet) but these are the steps and it may work.
OK if you selected Internet Sharing on the Mac you must also select
Share your Connection from - Ethernet (select ethernet) I think you would choose the Airport option since your are using a wireless card
To Computers Using - Airport (your iPad is the computer using Airport in this case)
Then you may have to select the Internet Sharing option again - put a checkmark in the box
Then go to Security in your preferences and select Firewall - turn off the Firewall to allow incoming connections to your Mac
Make sure you have Airport enabled on your Mac and go up to the Airport icon at the top of the screen, click on it, and drop down to select - Create Network. A box will come up and it should offer your computer's name as the default network name. You can name the network whatever you like. Then create a password.
This should be what you need to do to get connected. Once you do all of the steps on the Mac, reboot your iPad, go to Settings>WiFi>Network and select your new network.

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?

Airport Express and Internet sharing.

I have been told that I can share the internet connection, wireless, of a Mac that is connected to the internet via the ethernet port by using Airport Express. I am at a loss on how to create this environment. Can anyone help? I am trying to create a wireless network to use my itouch through internet sharing.

Please see this Apple Tech Help page.

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.

Airport iPhone Internet Sharing

hi,
I am trying to configure so that I can surf the internet on my iPhone through internet sharing my airport on MBP.
I have configured IP addresses manually and set the manual proxy to 10.0.0.1 on port 8080. When I ping the iPhone it responds between 6 & 8 times and then drops off never responding again until I start and stop airport and internet sharing. When i open Safari on the iPhone it instantly says it cannot find the server.
Personal Web Sharing is turned on. What am I missing here? This did work until I disconnected yesterday. Nothing changed in my settings and even though browsing was slow on the iPhone it was able to access webpages through Safari.
I'm thinking it is something to do with port 8080 ... it has become disabled for some reason.
Any ideas or pointers anyone?

I've been having the same problems as everyone else here. Trying to share internet connection from my ethernet wired iMac to my MacBook and my iPhone. Tried all the workarounds, but nothing works, or lasts very long.
Yesterday, I finally talked with AppleCare for over an hour. All their suggestions (trashing preferences, changing settings, etc.) failed, as well. The AppleCare person then put me on hold to speak to an engineer, who told her that Snow Leopard no longer supports Internet Sharing as of 10.6.1.
Not willing to accept that answer, I had them set up an appointment at the Apple Store Genius Bar for me, and after chatting with the Genius for a while, he also confirmed that Internet Sharing is no longer supported under Snow Leopard. Apparently, there were many hardware issues that the engineers decided to circumvent, and so did not include support for Internet Sharing with the internal airport in Macs. They said that the Airport it is intended to receive, not to send a signals! Yet, it worked fine, doing just that, under Tiger and Leopard! The only fix he could offer was to wipe my drive and take me back to 10.5, which I declined.
However both the guy at the Genius Bar and the lady at AppleCare inferred that Apple "may" release another update to fix this issue, if they get enough complaints and bug reports.
So, there you have it. Apple no longer officially supports Internet Sharing in Snow Leopard.

Port Forwarding hh3

i realy need to get some ports forwarded through my hh3 ive come from a hh2 with wireless dropping and internet dropouts to a hh3 that dosnt seem to port forward
help please

Hi,
Sorry I cannot help you, but I thought I would support you by saying me and my friend (me on HH3 and him on HH2) both have the same problem. It used to do it fine, but recently, not sure how recent, but recently, it simply will not open.
I think it is a firmware problem, so maybe some mods can clarify what is casing this issue or direct us to a list of things that completely prevent ports being forwarded. I have tried a full Power Cycle, full Factory Reset even, losing all my other open ports.
Help or clarification would be great about now!
Thanks, Stefano

Port Forwarding To Two Macs with Port 22 limitations

This is another port forwarding/port 22 issue and I've look around and not seen an answer to my specific problem. I work for a business that has an in-house ad system that runs on a Mac Mini. I have been accessing that Mac Mini remotely because we set up port forwarding through the Linksys rounter that is at the business using port 22. This is the only port that works for this connection to the mini and the software.
We are now adding a second Mac Mini to send the ads to a different set of monitors. I can't set up port forward to the new mini on the same port so I don't know how to connect to this mini remotely. Is there a way to get into the first mini through port 22 and then somehow communite to the second one through the first? Is there another way to do port forwarding...or have the linksys router switch from one mini to the other when a request comes in? There will only be one remote computer trying to reach either Mac Mini so there will never be simultaneous traffic coming in. Any help would be appreciated!
The linksys router is critical to the business becasue a host of other devices are forwarded though it as well.
Thank you.

Having set up my IP camera with HH4 successfully, I've now got another one and would like to set it up as well. I gave it a unique, static IP address which my router can see fine. When I try to set up port forwarding, I get a message saying:
"The game or application you’ve selected conflicts with an application (IP Cam 1) you’ve already assigned to another device. Please remove the other application or select the same device."
I am not being given the option to select the same device.
I'm now wondering if port forwarding to two identical devices actually works in principle with HH4? Has anyone else done this?
If in the Home Hub 4 A you go to
Advanced Settings
Firewall
Port Fowarding
Manage Games and Applications
You get the following statement:
"Each game or application can be assigned to only one device on your home network"
I would think that the only way round your problem is to have each Camera running a different application or the same application with a different name.
Does the remote browser app need to know the application name or just the device name ?
If you think about how Port Forwarding needs to function you need a way whereby the remote user needs to be able to tell the Hub what Camera to talk to.

Port Forwarding (for IP Camera)

I have so far been unsuccessful in in setting up my new ip camera for remote monitoring.
I have followed all instructions within the "bt homehub" domain for port forwarding in application sharing but when I check that the port (80) is open (using pfportckecker.exe) it returns "unable to ping your router" and "port is not open or available".
Can anyone help please - I am becoming very frustrated !
Thanks
Solved!

Thanks,

For "Unknown-7c-dd-90-05-5e-df" the bit in bold should be the MAC address of your camera. It is normally printed on the device somewhere.
You can rename this if you wish, by editing the name to something more appropriate.
You should have a created a custom rule called mikes-camera, which with:-
Protocol TCP
Start port 8080
End port 8080
Mapped to 8080
Leave the rest blank.
You should be able to assign this to the device.
A lot depends on which version of the home hub you are using.
What I have found by experience, is that it is better to use a static IP address, if your device supports it, as DHCP can be a bit unreliable when port mapping is involved.
You can use a static address outside of the DHCP range. Like 192.168.1.50.
You can still forward ports to it, by selecting the device by its IP address, not its name.
If you can view your camera within your own network, using http://192.168.1.69:8080 then you just need to persevere with the port mapping.

Internet Sharing problem with Airport Extreme

I can connect to the Internet with my iMac running 10.4.11 fine. The problem is that I can't share the connection with my laptop. When I go to System Preferences and select Sharing/Internet, Airport doesn't appear anywhere as a connection option. I tried running Airport Utility and I got the message, "AirPort Utility was unable to find an Apple wireless devices".
This all started when, originally, my laptop could connect to the Internet, but was unable to connect with the iMac. In System Preferences/Network I got a message that says "Your network settings have been changed by another application" and the only way I can get out of it is to force-quit system Preferences.

Hi,
Must ask, if you have an AE, why do you wan't to go through Internet Sharing?
When I go to System Preferences and select Sharing/Internet, Airport doesn't appear anywhere as a connection option.
You mean as a to: or a From: option?
