Airport for Internet with Wired Ethernet for local network

I'm trying to set up a small local network of 3 PC laptops connected via a router to a Mac which is acting as the central repository for the 3 PCs. The 3 PCs and the Mac are all connected by Ethernet cables to the router which is deliberately isolated from the Internet. However, I also want the Mac to use Airport to get access to the Internet via another router which does have Internet access and provides wireless support.
What happens is that the wireless Internet access for the Mac works OK as long as I have the Mac disconnected from the small PCs+router network. As soon as I connect the Ethernet cable to the Mac, it loses Internet access.
It seems that the Mac is preferring to try to use the wired connection over the wireless connection for Internet access.
How can I force the Mac to use the wireless connection for Internet access and leave the wired connection for my small local network? That is, how can I change the priorities for the two network interfaces (similar to the interface metric setting in Windows XP)?

read this and then look at this.. this is a screen shot of what you need to do..
http://www.ofzenandcomputing.com/wp-content/uploads/2007/02/Picture%203.png
if you share your wireless and tell it to share it THROUGH your ethernet you'll be okay..
another thing that you may want to do is to access your routers settings and tell it to work as a switch rather then a router. however if you can get it to work using the article up top then you might not need to do that.

Problem connecting to internet with wired ethernet

Shortly after installing the Leopard 10.5.2 update, I could not connect to the internet through the wired ethernet connection. Connected wireless with no problem. Spent time with Apple tech. Determined that the machine was fine. Told to check the wall port. Had a windows PC connect fine through same cable and wall port. Also brought the MacBook to a different location. Connected to the ethernet port and connected to the internet successfully. Determined that the MacBook kept using an IP address of 192.168.1.103. This is the wrong address for my connection. The correct IP address is 172.16.7.1. Installed this address manually in the MacBook and established a connection. The MacBook cannot seem to connect automatically at this location. The Windows PC connects fine. The MacBook keeps coming up with the wrong IP address. Any idea what could be causing this??

The IP address when connected to a router will start with 192.168.x.x.
When connected to a modem you will get a different address.
When you connect to a cable modem for the first time it looks at the Media Access Control (MAC) address of whatever is connected.
It is a unique number for your device.
It only attaches to one device and provides an internet connection to that device by way of an IP address.
If you wish to connect another device and get an IP address for that new device, you need the modem to start over, since it has a monogamous relationship with the connected device.
In order to have the modem drop its relationship, it needs to be restarted.
This is not true of a dsl modem.
It sounds like your modem has linked with the MAC address of the router.
In order to connect directly to the modem and get it to link to your computer, you need to unplug the router from power.
Disconnect its ethernet cable.
Restart the modem after about 15 seconds and wait until it restarts, about 2 minutes.
Then reconnect the modem and you will likely be able to connect to the internet.

Can I use wifi for internet, while ethernet only for local network?

Hello everyone. We have two internet connections at our office. One is wifi only -- but fastest uploads. The other is connected to our ethernet network (and very slow). Really, it's not much a network -- just iMacs connected to a switcher. When transferring files between iMacs, obviously we want to remain connected to ethernet. But when uploading and downloading files, the wifi option is quickest (long story why -- our offices next door, can't run a physical line yet, yadda yadda).
So we find ourselves constantly switching between the two in network preferences. Not only is this a pain, but it doesn't allow us to upload or download directly to a drive on the network.
Is there a way to tell the preferences to use wifi for internet, and ethernet for the local network (without internet)?
(We have updated mountain lion on i7 imacs, and most recent airport extreme)
Thanks!

Your downstairs router can be installed anywhere in your home, but telephone companies or ISPs are only obligated to install their equipment just barely inside its service entrance. Usually, that location is the worst possible one for a home network, since it's in a basement or some remote corner, far from all the devices that use it.
Your idea to install an Ethernet cable to extend its reach to a more suitable location is an excellent one and will be worth the effort or expense. If you don't want to do it yourself a qualified electrician can perform the work quickly and elegantly, and you may find the cost surprisingly affordable. Ask your friends and neighbors to recommend a reputable electrician and get a written estimate.

No Internet with Airport Express - Internet with ethernet

I have achieved frustration.
I have searched and searched the forums for the answer to this, and all I find is "reset the modem"
iMac
OSX 10.6.1
Airport Extreme
Airport Utility on iMac
Arescom Netdsl 800 modem
Qwest ISP
I can connect to the Airport Express, seamlessly with the Airport Utility.
However, I do not have Internet.
If I take the ethernet cable out of the Airport Express and plug it directly into the iMac, I have lightning fast Internet.
Can anyone help me out? Can anyone point me in a direction?
Thanks,

I don't see anything unusual with the modem information that would prevent a normal installation.
Try a factory reset on the AirPort Extreme (AEBS) as follows:
Pull the power for a few minutes
Hold in the reset button and keep holding it in as you plug the AEBS back in to power
Release the reset button after approximately 8-10 seconds
Connect the ethernet cable from the modem to the WAN (circle icon) port on the AEBS and use AirPort Utility to reconfigure the device. The main settings that you will choose are Connect Using "Ethernet" and Connection Sharing would be "Share a public IP address"
It's possible that you may get a Double NAT error notice. You can click to ignore this warning.
See if that might help.

How to set up with cacheing DNS for local network?

Our new Lion Server has a static IP Address pointed to over the internet by our registrar's zone file. Planning the Lion Server installation process with the intent of hosting Web, Mail and Open Directory services to a small number of users who are nearly all located off-site. I do also want Lion Server to be a caching DNS Server and DHCP authority on the local network to replace what dnsmasq does on our current Linux server.
I am looking forward to offloading some of the lower level Linux administration tasks and putting myself in the hands of the Lion Server Setup Assistant and Server App :-) but at the same time don't understand some of its assumptions and fear having to spend a lot of time experimenting and re-installing.
So, specifically, I want the Server App to know that my Lion Server has a "Host Name for the Internet" but that the DNS it sets up will not be the DNS for my zone - I will be managing that through my registrar's interfaces.
Second problem is my fnot understanding what name space devices on the local network will / should use. e.g. The Linux server will be available for backups etc on the local intranet (and optionally have a static ip address on the Internet) but MacBooks, PCs, iPads and iPhones will be served ip addresses by the Lion Server's DHCP. So will / should these dynamic devices have their machine names fully qualified by our domain name with RFC 1918 style ip addresses or something like .local? How do I tell this to Lion's Server App / Setup Assistant? How easy is it to update these initial settings later?

You do indeed need to have a master zone on lion server. There's no way to get around that since Open Directory depends on Kerberos and Kerberos depends on the DNS. LS scripts may see that the rDNS record exists, but I highly doubt that it'll auto configure everything for you... and given the number of possible variables, I bet that even if it worked something would need additional tweaking.
Sounds like an interesting lab excersize. You should try it on a test server!
Again... you just need to folow the set up procedure that Lion Server presents you with.
It won't be smart enough to see your external records and use them to configure a key distribution center for your OD.
As far as your caching needs... Could you set up your DHCP server to set the DNS server setting to show your internal server as the first hit, and your external as the second? That way when the client requests a resolution it'll not get a hit on your local server but will from the external?
The question then is how long will it wait for a response from the first server? Or will the first server respond with "I don't know" sending the client immediately to the second.
The server set up that I have works similarly. I have an internal master DNS that is replicated to a secondary. The first DNS has an A record (community.server.com) that points to the INTERNAL ip address of the secondary server that's also running the web service. The first server is running DHCP. It tells the clients to use the first and second servers as it's DNS lookup.
Now... Externally, my registrar hosts an A record for community.server.com that points to the external IP address of my router which then forwards the request to the proper port on the internal network.
This way, the local clients internally look up and get a response locally when they go for community.server.com. Externally, clients that look up community.server.com get the external connection to the router in my school.
Yikes... I fear that this is as clear as mud!

Airport Express Problem with Wired/Wireless networks simultaneously

Hello,
I'm having trouble maintaining a connection with my AX (2012) in a work environment. Basically, I have a Win 7 laptop connected via ethernet to the internet/corporate net. I have configured the AX to create a separate wifi network that does not connect to the internet. In order to connect to the AX, I have to disable both the Ethernet adapter and the WLAN adapter, enable the WLAN adapter, connect it to the AX's network, and wait for it to show up in the utility. Only then can I re-enable the ethernet adapter for internet access. Then, inevitably, the connection dies within 15 minutes and I have to repeat the whole process.
Can anyone tell me what's going on here? Is the wired network interfering with the wireless network? Is something configured wrong? Below is the output from ipconfig/all, if that helps. The AX is configured with a 169.254 range. IP address and behaves the same way whether the IP address is auto or manual, and there is no difference if the signal roams channels or is fixed to a single channel (I've played with them all).
Thanks in advance for your help.

Here goes - read this through completely and see if it makes sense:
1. Reset the Express to factory settings by unplugging it and plugging it back in while holding in the reset button - release the button when the light starts blinking - then wait for the light to blink slowly indicating factory default.
2. Disable the wireless and enable the ethernet on the laptop and connect an ethernet cable to the WAN port (the circle of dots) of the Express and use the AU toset it up in bridge mode to create a wireless network with a name of your choice - you don't really need a password but you can assign one if you wish - if you do not use a password you will have to choose to ignore the error message for no security.
3. Accept all other defaults and ignore any messages about not having an internet or ethernet connection and update or finish the setup - if you get a blinking amber light, open the AU and correct any error messages.
4. You can now disconnect the ethernet cable and disable the ethernet on the laptop and enable the wireless so you can stream iTunes to the Express - the laptop must stay wireless to do this - you can not accesss both at the same time - you can also use an iPhone or iPad or iPod to use Airplay and then you can use the laptop via ethernet for the internet.
5. To access the Express from now on, you have to use the AU wirelessly from the laptop.
The above is assuming that you don't currently have wireless in your office - the other alternatives are:
1. To hardwire the Express and have it create a wireless network and access the internet - you could then use your laptop wirelessly or wired to connect to the Express and use Airplay and your pc at the same time.
2. If your office has wireless, you can set up the Express to "join" the existing network - you can then do the same as in number 1.
I hope this helps - everyone's situation is different - the above scenarios work for me - you might have to do some tweaks but the info is there - let me know if you have any questions.

Using Airport for office network and still connect to public wifi

HI
I work in the public sector and we have open public wifi network that we can connect to, but have no control over and would never be given no access by our service user. we are a small sub contractor in a office tucked away.
We have 3 Macs and 2 wifi printers and several iPhones and iPads, our thought was to link them all and create a mini local network using the Airport extreme but still stay connected to the Wifi. as the only other option would be a 4G router but that is hit and miss with the connection.
After much stubbornness on my behalf i can not seem to fathom a way round this problem, is there a solution with the devices we have
Ian

No we can't get access from the company we work for they let us have wifi access only with no controls.
and the building has no phone access as we are in the middle of a hospital.
the office has all its devices and printers that we can't link but separately we can connect to the guest wifi

Config AirPort for a network that needs login

hi. my university requires a login to use the Internet. That means that I can only have one device connected at a time.

Easy filesharing setup for local network

Hi folks,
I'm currently trying to enable easy filesharing for my local network.
Yesterday I installed Ubuntu 9.10 on a Laptop and it just worked.
But I can't get filesharing to work under Arch (Chakra 64bit Beta 4) witch kde4.
Samba is installed, the daemon is running... i cant figure out why it doesn't work.
When I open Dolphin and go to Network I can see all the PCs in the local Network.
After opening i can see 3 things (when looking at the system i am currently working on):
<hostname>[00:21:5d:72:b4:84] (has kind of a Networksymbol)
<hostname> (has a shell-symbol)
SFTP File Transfer on <hostname> (folder symbol with world in front of it)
when clicking on the first one with the strange numbers, dolphin crashes.
I dont know why! what i would like to have is a real symble filesharing for my local network i dont mind whether its nfs oder samba or whatever.
thanks for help!

We only want to connect/browse the server locally , so I'm a bit stumped on the need to set up DNS.
Ideally i would like to browse the server directly by entering the IP address (and port number if need) followed by the site name.ie:
By default, virtual hosting setup via Server Admin use name-based virtual hosting, meaning that Apache looks at the hostname in the request to work out which site configuration to use. That's why you need DNS - a way to map the numerous names to the various sites you've configured, e.g.:
http://site1.server.local/ -> site 1
http://site2.server.local/ -> site 2
(where both site1.server.local and site2.server.local resolve to this server's IP address)
It is possible to do port-based virtual hosting (where you include the port number in the URL) - to do this you leave the hostname blank in Server Admin and ensure that each site has a different port number configured.
http://server1.local:8001/ -> site 1
http://server1.local:8002/ -> site 2
There's no easy way to map URI elements to different sites, e.g.:
http://server1.local/site1 -> site 1
http://server1.local/site2 -> site 2
This can be done by editing Apache's configuration directly, but you can't do this via Server Admin (unless you really are just mapping to different directories and not entirely different sites).

Changing ID of host machine for local network

I don't have a local network yet I keep getting messages that the OS has changed the identity of my machine in order to allow file sharing!! "FirstName-LastName-.3 has been changed to .4" Nothing seems to change in terms of operation, but it is irritating and I wonder why it's happening. I have "File Sharing" off.

K T wrote:
this happens when the system detects a computer by the same name on the same local network.
It's also happening when there is only one computer....which is apparently the OP's situation as I took it.
yes, I know. what I meant is that the computer thinks that there is another computer by the same name on the network. it does not mean that there is actually another computer by the same name present, just that your computer thinks there is one for some reason. resetting the router is the first thing to try in such situation.

OS X server for local network Drupal web development

HI All,
First post here, so here goes, please go easy
Background
We're a small web development shop and bought a mac mini server so we can collaboratively develop our websites. Previously we have all been using MAMP on each of our local machines to develop Drupal websites.
*Help needed*
I've tried configuring some custom sites through the web services preference pane, but have no luck in viewing these custom sites from our other mac clients.
Ideally we want to virtual host multiple sites on our server that we can see on our local network.
We only want to connect/browse the server locally , so I'm a bit stumped on the need to set up DNS.
Ideally i would like to browse the server directly by entering the IP address (and port number if need) followed by the site name.ie:
http://myserve.local/mydevelopmentsite
Essentially, i would like to replicate MAMP functionality - hosting multiple sites on the server that can be collaborated on from the local machines.
I've really found it hard to find any configuration information via search, most topics seem to refer to modifying regular OSX installs to work as a server. My understanding is that as OSX server has all the necessary LAMP components that this should be a fairly straightforward task.
If anyone can share any links, advice or tutorials that would be much appreciated.
Best Regards
Hixster

Network Service Order Causing Conflict with Private DNS on Local Network

I'm currently working on deploying a Snow Leopard Server-based setup for a university student-run television station, using a Mac mini Server. Because our university's own networking infrastructure is somewhat wonky and restrictive, I have recently networked our station's six other computers and the Mac mini Server together through wired Ethernet, using an AirPort Base Station as a router along with some D-Link Ethernet switches.
As a result, our computers are networked together on their own network completely independently from our university's network, but because this wired network has no internet access, all of our computers connect to our university's wi-fi network over AirPort for internet access.
I've set up Snow Leopard Server with a private DNS name "atvserver.private" and am intending to use this server internally for file sharing, directory services, and Wiki Server (and possibly Podcast Server). However, because of the service order in Network Preferences, if our client computers are set to give AirPort priority, then they can connect to the internet, but cannot connect to the server's private DNS. On the other hand, if our client computers are set to give Ethernet priority, they can connect to the server, but lose their internet connection.
The only solutions that I can think of are:
1) Bridge the university's internet connection on our private wired network (but the university will not allow us to do this because it violates their security policies), or
2) Come up with some way to bypass the networking service order so that "atvserver.private" goes to the Ethernet network, while everything else goes to the public internet over AirPort.
Any ideas on how to solve this problem?

What's the ip range an subnet for the university network
The issue has nothing to do with the IP addresses/subnets in use. It's about DNS resolution.
Fortunately the solution is simple.
Configure the DNS server on the SLS with the zone(s) for your private LAN.
Enable DNS forwarders with the IP addresses of your university's DNS servers.
Point your clients to your SLS for DNS service.
Now all DNS requests from these clients will go to your server. For zones this server is responsible for (i.e. your private LAN) the server will reply, for all other lookups it will refer to your university's DNS servers for resolution.
In this way your clients can resolve your private zones, the university's zones and public DNS hostnames. Problem solved

Use FaceTime with both users on local network?

I'm trying to use FaceTime with a user on the same local network. It doesn't work. Any ideas?
Thanks.

Completely reboot both phones ... be sure your wifi is linked (on both phone) That's as much as I know ...
I've FaceTimed on the same wifi signal w/out any problems so, it should be just a simple restart.

I have an apple tv but lost the controller I connected my apple tv to my internet with an ethernet cable and it worked fine for the past week it has now stopped working

Can airport be setup with an ethernet connection?

I'm having challnges setting up my Airport express via ethernet cable connection directly to my router. It will setup wirelessly no problem, but I occasionally get dropouts when streaming music and I'm hoping to remedy that with a direct cable connection.
I believe I have to turn the wireless option off via utility, which I did, but still having issues - can anyone provide some insight as to the proper settings to connect it via ethernet cable?
Here is my setups if it helps:
Airport express, model A1264 (which is 2nd gen I believe)
Cisco router (provided by my intenet provider)
Macbook Air, running 10.8.5
Airport utility version 6.3.1
Thanks!
Phil

AirPort Utility 5.5.3 will work fine for that.
Reset the Express back to factory default settings as follows:
Power off the Express for a few minutes
Then, hold in the reset button first, and keep holding it for another 10 seconds while you simultaneously plug the Express back in to power
Release the reset button and allow a full minute for the Express to restart to a slow, blinking amber light
Connect the Ethernet cable from a LAN <-> port on the Cisco router to the Ethernet port on the Express
Open up AirPort Utility 5.5.3, click on the AirPort Express, and click Continue
Enter a device name that you want to use for the Express and password, etc.and click Continue
Choose the "Join" option, then click Continue and then click the option for the Express to disable the wireless and have the Express connect to the the network using Ethernet, then click Continue
Review the settigns and click Update. Allow a minute for the Express to restart.
You may now need to restart both the Cisco router and the Expess and you should be all set.
