Printer sharing across internet sharing

I hope I don't confuse everyone with this.
I have three computers—an iMac running Snow Leopard, an iMac running Lion, and a Mini running Leopard. The SL iMac has a printer plugged into it. The other two computers are across the house from it.
Those two computers are next to each other. The Lion iMac is connected to the Internet via WiFi. The Mini, which does not have wireless, is connected to the Internet via Internet Sharing over an ethernet cable to the Lion iMac.
Now here's the problem. I can print from the Lion iMac through printer sharing across to the SL iMac. However, I can't figure out how to print from the Mini. It won't find the SL iMac's printer. Enabling printer sharing on the Lion iMac lets the Mini see it as a 'printer,' but it won't print across to the SL iMac.
So with this setup, is it possible to print to the SL iMac from the wireless-less Mini?
Just to ward off possible non-workable solutions, rearranging the computers is not feasable right now. It is also not possible to connect the Mini directly to the internet via ethernet. My cable modem is actually in a near-inaccessable part of the house due to that being where the only cable plug is. I have a Time Capsule attached to it, which broadcasts my wireless signal that the WiFi computers can pick up. And no, I can't connect the printer to the Time Capsule—believe me, I tried. I don't want to have to start buying long cables and drilling holes if there's a simpler solution.
Thanks in advance.

If I switch to the discussed set up (Airport Extreme N router), will adding an AX in between at 15 feet help bridge the link between the G5's Airport extreme card and the living room's AX?
Yes. But I still think you should verify if Wi-Fi interference is the cause of your poor signal only 30' away from the AX before going out and purchase anything. Remember, you will tradeoff bandwidth performance for signal strength. With audio, this can be a negative factor.
If you can get a hold of a laptop, I suggest downloading a copy of iStumbler. Use iStumbler's Inspector feature (select Edit > Inspector from iStumbler's menu) to determine the Signal-to-Noise Ratio (SNR) at different points around your house, by performing a simple RF site survey. Within the Inspector, note the values for "signal" & "noise" at these locations. Start with the laptop near the AX, note the readings, and then, choose the locations between the AX and, finally, where you have the G5.
SNR is the signal level (in dBm) minus the noise level (in dBm). For example, a signal level of -53dBm measured near an access point and typical noise level of -90dBm yields a SNR of 37dB, a healthy value for wireless LANs.
The SNR, as measured from the laptop, decreases as the range to the base station increases because of applicable free space loss. Also an increase in RF interference from microwave ovens and cordless phones, which increases the noise level, also decreases SNR.
SNR Guideline
o 40dB+ SNR = Excellent signal
o 25dB to 40dB SNR = Very good signal
o 15dB to 25dB SNR = Low signal
o 10dB to 15dB SNR = Very low signal
o 5dB to 10dB SNR = No signal
If the SNR is 20dB+ at each of these locations, then you should be getting reasonable performance from your AirPort. If less, either try to locate the source of the Wi-Fi interference or try relocating the base station or the G5 until they are within a 20dB SNR range.

Screen-Sharing and Internet-Sharing via same network connection

Hello out there,
I'm using a TiBook (G4 867MHz) and a MacBook Pro 17". They are connected via a WLAN-router. Additionally the MBP is connected to the internet via an UMTS-connection established with a Merlin 870XU type PC-card.
Network is working fine, including screen-sharing. Also the internet connection on MBP works without error. But if I activate Internet-Sharing via WLAN to get my TiBook connected to the internet, the MBP connection to the WLAN is cut off.
Can somebody tell me what's going wrong and how to solve it?

Sharing behind Internet Sharing NAT

I have a product demonstration that will require the internet being shared from my cell to two devices via ethernet. One is hard-wired to the physical ethernet port. The other is a virtual machine configured to look like a separate device on the network (VMWare Fusion 6, not that it matters). This is the only hardware I'm allowed to bring into the facility: phone, laptop, and the one physical ethernet device.
From a topology standpoint the network would look like this:
[Internet] -- [4G -- iPhone -- tethering wifi] -- [wifi -- MacBook Pro via Internet Sharing -- ethernet] -- <two devices, A and B>
I'm attempting to use the Internet Sharing-configured NAT on the ethernet port like a typical consumer router: 1 WAN port, 2 LAN ports.
At this point, enabling Internet Sharing allows both devices A and B to connect to the internet. However, devices A and B cannot ping one another.
I've been digging into PF and 'pfctl' but I'm not seeing how to allow traffic between A and B. It's as if the virtual bridge setup by Internet Sharing is unable to act as a switch for the "local" side of the NAT.
Does anyone know how to enable this functionality of Internet Sharing to allow A and B to communicate on any port? Or perhaps have a different solution?
Thanks for any help.
Thomas

Happy to hear alternative ideas to this one... This is a goofy fix:
In System Preferences, be sure you have disabled Internet Sharing before trying this.
1) Navigate to the System Preferences -> Network and click the + to add a new interface. Make it ethernet and give it some name.
2) System Preferences -> Sharing -> Internet Sharing -> Enable whatever your internet-connected interface is to hook to "both" interfaces labeled Ethernet (despite different names, both showed as "Ethernet" for me).
3) In VMWare Fusion, choose to bridge your VM's network interface with this second, fake, Ethernet from #1.
4) Boot the VM.
What you should see is that the VM still gets assigned an IP address, but the configured NAT that provides the Internet Sharing ability now can see and route between two connected interfaces. Otherwise it seems to think the single ethernet is exactly 1 device despite there being two MACs using it.
Cheers!

Screen sharing across internet

I had set up my Mac for screen sharing with Lion and was able to share the screen to another Mac on the local network, or VNC across the internet. Upgraded to Mountain Lion and screen sharing continued to work both locally and remote.
Moved to Mavericks and now the screen sharing works locally, but will only work for about 30 minutes across the internet. If I reboot the Mac, then I can access the screen across the internet for about 30 minutes, then the connection drops and I would have to reboot the Mac again.
I have screen sharing turned on by:
System Preferences -> Sharing -> Screen Sharing. Clicked on 'Computer Settings...' and checked 'VNC viewers can connect...' and gave it a password.
I can access this remote Mac across the internet using either JollysFastVNC, or the screen sharing app via Finder. Turns out that remote command line and Finder also can access this machine for about 30 minutes, then connection drops.
Has anybody else seen this problem, or have any suggestions on what I can try to keep remote access working for more than 30 minutes?

I don't have a solution (yet). I have the same problem with a Mac Mini remotely. After some short length of time, my ability to control remotely vaporizes. The Mini is running 10.9.1. It seemed to work ok earlier - although the previous version of Mavericks kept screen sharing from working if the firewall was enabled at all. The last system update from Apple fixed that.
But this isn't universal. I can connect with LogMeIn to the Mini after a fresh reboot, but eventually (30 min?) all I get is a black screen. I can connect with LogMeIn to a MacBook Pro on the same remote network as the Mini and it works just fine. I can even connect with LogMeIn to the MacBook Pro and then do screen sharing to the Mini on the same remote network - until that 30 minute? window has elapsed, and then screen sharing fails to connect without even telling me it failed (no black screen, no alert, nothing). Then that doesn't work either. File sharing from that MacBook Pro to the Mini on the same remote network continues to work, and server applications continue running fine on the Mini. For some reason the only problem is that I can't *see* the remote Mini on 10.9.1 for more than a short period after a reboot. All 3 computers involved are running 10.9.1, but only one (the Mini) is failing like this.
It sounds like the problem you are having. If I figure anything else out I'll let you know.

IChat-initiated Screen Sharing across Internet

For those of us supporting Aged Parental Units and their Macs, iChat Screensharing is the Killer App to end all killer apps. And when it doesn't work, it's really frustrating.
One thing that makes iChat Screensharing preferable to Timbuktu or generic VNC shareware is that I don't have to walk the "computer illiterate" (can they retire that cute phrase in 2009?) through configuring port-mapping on his NAT router. "All" I have to do is talk the user through:
1. getting an AIM i.d.
2. configuring iChat to use that AIM i.d.
3. finding System Preferences > Sharing, and enabling Screen Sharing
+(have I forgotten anything?)+
At that point I should be able to ask to share the other person's screen. The really big piece of magic, *contacting someone who is behind a NAT router*, is handled; I presume by some clever sleight-of-hand by the AOL server which the AIM client is logged into.
Okay: I can't get it to work for my father. He's running 10.5.6. I can screen-share using the iChat interface when I'm on the same LAN as he, but not from outside.
His firewall is off. His router is an Airport Extreme, to which he's connected by ethernet cable. The Airport Extreme configuration is about as vanilla as it gets.
Can anyone spot something I've forgotten to do, or ask a followup, or suggest the next troubleshooting strategy?
Thanks,
Chap

Hi,
It is somewhat of a feature that Getting iChat to work depends on the devices used at each end.
iChat has to be able to identify very clearly where it is in relation to the Internet for it work/connect in Video and Audio chats.
As far as we can tell Video and Audio chats will work if you Port Forward certain ports Or allow them via other methods such as Port Triggering, DMZ or UPnP.
We know the ports through using Application like Little Snitch and also Apple have published them.
For Tiger and Earlier http://support.apple.com/kb/HT1507?viewlocale=en_US
For iChat 4 in Leopard http://support.apple.com/kb/HT2282?viewlocale=en_US
What the second one does not tell you is that you need some of the Info from the first if using Bonjour or Jabber IDs as well as AIM.
It also fails to say anything about the Screen Sharing.
AS I have said before the Testing that some of the Regular posters have done show that Screen Sharing seems to be a Random port, separate from the Audio component of that connection.
As you will see from the two links the title includes the mention of NAT (Network Address Translation)
Port Forwarding, Port Triggering and DMZ all rely heavily on NAT being done in the routing device.
UPnP seem less reliant on NAT to get through any routing device.
If you have a modem that routes it is likely that it is issuing IP addresses to the computers (DHCP)
IF you then add a router that also does DHCP then the computers get two IPs (Although they can only display one)
iChat can not cope with this.
It is possible to get a router as well as a non routing modem to pass the Public IP to the computer which would exclude the need to open any ports (As they would All be open)
An Base Station can be behind a Routing Modem and set to Not be a router (Just a wireless access point) which would also preclude the need to Set Port Mapping Protocol in it.
We are in the land of "Ifs, Buts and Maybes" when we try and cover all the possibilities that people may have when dealing with a certain lack of information.

Printer/Internet sharing over ethernet not working

Due to unsolvable problems with Airport and 10.5.2, I've decided to set up an ethernet network between my Mac Pro and MacBook. I have an ethernet cable going from the ethernet 2 port on my MP to the MacBook. I am able to establish a file sharing connection, so I know that the cable is working.
However, I cannot get printer sharing or Internet sharing to work.
I have enabled printer sharing in Print & Fax preferences, and selected the USB printers I want to share. But when I go to Print & Fax preferences on my MacBook, although I do see my printer when I attempt to add it the preferred driver does not show up and it selects "generic postscript" instead. This is completely strange, because when I go through the same process when the MacBook is connected to my Airport network (when it isn't dropped out), I am able to add the printer with the correct driver without a problem.
As far as Internet sharing goes, there's nothing happening at all. On the MacBook when I open Network preferences it says "Built-in ethernet isn't connected". I don't know what I'm supposed to do to get this going. I already have enabled Internet Sharing on the Mac Pro ("share built-in ethernet 1 connection with computers connected to ethernet 2"), but I don't know what to do beyond that.
Do I need a switch?

sure, there are workarounds. I was trying not to spend any money!
Mostly I am curious what caused it to stop working.
Thanks for the input!!

How do i set up internet sharing

Hi everyone,
had internet sharing on my imac before upgrade to lion, now nothing. Anyone help

Have you tried to set it up afresh?
System Preferences>Sharing, tick Internet Sharing and then from the drop down menu select what connection you want to share. Should be clear from there. Worth adding security using the wifi options button.

Nokia 520- Internet Sharing Issue After WinPhone 8...

I recently updated my Lumia 520 (AT&T) to WinPhone 8.1 OS. Since the update was installed, I am unable to turn on my internet sharing (mobile hotspot). I receive the following message on the screen, "Connect not shared. To enable tethering on this device, go to att.com/mywireless or dial 611." I have spoken with AT&T technical support on several occasions and they do not see an issue with my plan. I also have a second device (another Lumia 520) on my plan that was currently running WinPhone 8.0 and successfully sharing internet as a mobile hotspot. Today, I manually updated the OS on that device to WinPhone 8.1 and as expected, the internet sharing functionality stopped working after the update.
I have looked through various message boards and posts related to similar issues, however I cannot find one that is directly attributed to the WinPhone 8.1 update.
Any ideas or assistance would be greatly appreciated.

Thanks Abi99
After I pulled the battery to get the product code, the error message when I try to start ICS changed to: Connection not Shared. Internet sharing isn't currently available
I am still on AT&T. However, I ported the number (not the device) out to T-mob and then back to AT&T 3 weeks later. I used the 520 on WiFi in the interim 3 weeks, and during this time, it received the 8.1 update notification, and I installed 8.1.
Which connection profile is choosen in Lumia » menu » settings » celluar+SIM » SIM settings?
Active network: AT&T
Data Connection: On
Don't Roam
SIM Settings: SIM
No data under APN settings (all fields empty)
add internet APN » APN wap.cingular » save » power off » power on: Does it work?
Tried, doesn't work
add internet APN » APN phone » save » power off » power on: Does it work?
Tried, doesn't work. But after this change, the error messgae goes back to the original one:
Connection not shared. To enabled tethering on this device go to ; http ~ or dila 611

Ad Hoc Internet Sharing

I have a windows PC at home and a Powerbook. I want the PC to be directly connected for serving purposes, but would like to be able to have both comptuers on the internet, without using a router. I got a wireless USB key for the PC, and now have it set up Ad Hoc with Internet Connection Sharing active,
The powerbook can see the network in the airport menu, but neither the file sharing, or internet sharing options are working.
possible solutions anyone? thank you

Problem in Internet Sharing from Ethernet to wifi

Whenever i go to Preferences > Sharing > Click Internet Sharing > From Ethernet > to wifi and hit start. It actually creates my wifi access point but the problem is that i lose my internet connection from both, my mac from which the connection is being shared and my cellphone which is connected to it. I can not identify what is the problem, but i have tried it many times with or without the WPA2 personal key. Even after stopping the internet sharing, i have to plug out and then in my ethernet cable in order to connect to internet.
This problem was also on OS X mavericks with me last year, but it resolved automatically, i don't know how. But since when i have upgraded to yosemite, i can't make my hotspot connection working . Suggest any quick and effective way please.

Same problem over here...
Additionally: if I unplug Gigabit-Ethernet-Adapter and plug it in again while Internet Sharing is still activated, the internet via ethernet works, but breaks down again about a minute later...

Internet Sharing With an iPod Touch??

I've done a search and couldn't find anything. This might be better suited in a different forum but I'll try it here.
I've got two laptops. The first is a MacBook (Intel) and the other is a PowerBook (PPC).
I've been using the MacBook for all my work with my Touch. I do not have wireless at work so I use my MacBook and just share my internet via airport to get my Touch online. It's been working without any problems. For some reason my MacBook crashed earlier today (screen froze except with a message box that said I need to restart my Mac). No problem I shut it down and did some BS for work. I got back on it today and haven't had any problems but now my Touch will not get online via the MacBook. It sees and connects to the MacBook wireless but it doesn't have any connectivity. It gets an IP address assigned, but I can't get anything on it.
Thinking it was my computer I tried my PowerBook and was able to get online with the PowerBook via the shared wireless network on the Macbook. Also, I can plug the LAN cable into the PowerBook and the Touch will connect through it using the internet sharing.
I was thinking that it was a difference between the PPC and the Intel chips but the Touch was working on the MacBook a few hours earlier. I am running the same basic system on both computers and for the most part they are running the same stuff.
Any thoughts?
Thanks

After a long time i think someone has found a way to get internet sharing working with the ipod touch.
found this post by "coolisstillgood" in macforums and it worked perfectly for me.
+"I've seen a lot of posts and notes about this topic over the internet and non of them could solved my problem completely,they were partially helpful but not entirely helpful. there were tons of complains about this matter and a lot of users seemed unhappy because simply they couldn't share their Internet Connection over airport or wifi with their iPod Touch. After a long and tiring night I finally figured out how to get it right and I decided to share this experience with all the Mac users gladly.+
+Ok, what I have is a MacBook with OS 10.5.2 installed and my Internet connection is through cable modem and it's a Ethernet Connection and I shared my Internet through Airport with my iPod Touch.+
+I assumed your Internet Connection is fully established and you can surf the web with your MacBook.+
+you go to System Preferences and under the Internet & Network, you go to Sharing,Turn On Web Sharing and Internet Sharing,in the Internet Sharing you have to choose to Share your Connection From Ethernet(in case you get your Internet Connection from Ethernet of course) To computer using Airport .+
+And then on your iPod touch you go to Setting and the Wi-Fi,you should see your computer name there,choose the network and then press the ">" sign in the blue circle,you should see your IP Address which probably is 10.0.2.2 . What is important here is your DNS which probably should be something like this format 10.0.2.1+
+you go back to your Mac and System Preferences>Network>Airport you should see your Computer's Name in the Network Name field, you go to Advanced>TCP/IP and write down your IPv4 Address, go one step back which is System Preferences>Network and this time you go to Ethernet>Advanced>DNS on the right side,there is the list of your DNS Servers,you add your DNS number form your iPod Touch and your IPv4 from your Airport configuration and that's it.+
+you should be able to browse internet from your iTouch by now.+
+And for all the IP stuff,you let DHCP handle it Automatically. I did it and it works fine for me and the speed is pretty good too and there is no need for a wireless router. You can share your Ethernet Internet Connection Easily from Airport to your iTouch.+
+I hope this post will be useful for ones struggling with this problem.+
+keep it cool"+
follow the instructions exactly and good luck!

IMac creating VPN for ATV 2 via Internet Sharing...

Apologies for the complex nature of this problem/question. Any guidance you (the great and the good of the Apple eco-system) can offer will be gratefully received.
First up, most of what I set out below works fine. Or should I say, it all works fine, but intermittently fails on me. And I realise it's possibly a 'home network configuration' issue, but I'd still appreciate someone with the requisite skills checking this over....
The following feature in my set up, all running latest software versions:
1. a late 2012 iMac running Mountain Lion.
2. an Apple TV 2.
3. a first generation Time Capsule.
4. a Strong VPN account.
5. an ADSL modem / router.
As it stands:
the Time Capsule is connected to the ADSL modem via Ethernet.
the ADSL modem / router is configured as DHCP.
the ADSL modem / router is configured to provide a 802.11g network - SLOWNET
the Time Capsule is configured in Bridge mode.
the Time Capsule is configured to provide a 802.11n WiFi network - FASTNET
the iMac is connected to the Time Capsule via Ethernet.
the iMac is configured to establish a VPN connection.
the iMac is configured to create a WiFi network - VPNNET
the VPN connection is shared using 'Internet Sharing' to users of VPNNET.
Apple TV connects to VPNNET.
All works, and all is well. EXCEPT:
1. regularly ATV loses the connection to VPNNET, usually when it (ATV) hasn't been used for a while, hence VPNNET likely to have been disconnected / reconnected since ATV last accessed it. Having lost the network connection, it can take over one hour to get it back. Sometimes it can't see VPNNET, sometimes it connects but can't see the Internet - and occasionally I've changed DNS server address in ATV to Google (8.8.8.8) and it kicked it back into life.
2. Home Sharing on ATV doesn't work when it's connected to VPNNET - I have to connect to FASTNET to get it to work.
So the questions I have are:
1. How should DHCP be set up on my network, Time Capsule, modem / router, doesn't matter? What about on the iMac for VPNNET?
2. Is there a way to configure the above kit, and have the VPN and Home Sharing working at the same time?
3. Where / How should DNS be configured in my set up?
As I write this down I'm forced to acknowledge just how involved it is, and don't hold out much hope of someone coming along with a simple "change these settings and problem over" solution - but I can live in hope!
Thanks for reading to the end.

Proxy via Internet Sharing

Hello, Apple Communities.
I am having some problems with proxy setting.
I contacted Apple about it, and they couldn't give me any solution,
So I was wondering is there anyone who can figure it out.
I am trying to use proxy, via internet sharing.
Which means, I would like keep the proxy setting universal through out internet sharing.
For instance, if I use internet on my iPhone through my mac(=internet sharing), I wish my iphone on proxy.
But apparently the proxy setting,
actually all sercutiy settings are not shared on internet sharing.
Is there anyway to fix this?

My only advice would be to buy a router like the airport extreme.

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.

Can't see printer or shares when connected via Internet Sharing

I recently switched from a 2006 to a 2008 Mac Pro. Rather than do a migration I simply took the hard drives from the old machine and put them in the new one.
I then upgraded to Mountain Lion.
I use Internet Sharing to share my Mac Pro's Ethernet connection via wifi, but the other Macs can't see the Mac Pro's printer or shares when connected in this way. They can access the internet. If I connect a machine via the LAN rather than Internet Sharing, the shares and printer are visible.
This worked fine on Lion on the old machine. Any ideas?

Seems that the issue is something to do with connecting via WPA2. When I set Internet Sharing to use WEP (by option-clicking the security menu), I'm then able to see the network shares and the printer.
