Mac as a router

I know how to setup my mac as a router. Given the fact that my macbook is connected to the ethernet.
However, is it possible while my mac is connected to a router (via Airport) and at the same time share my internet to other computer via airport as well? I set it up already but the connection between my mac and a router is disconnected. This is on a scenario that I don't need to buy 2 internet cards in a coffee shop for instance. Just 1 mac connected and share my internet. You get the idea I think so. Thanks guys.

No, this is not possible. Internet Sharing won't even let you do it. You can share an internet connection obtained via AirPort with another computer through ethernet or firewire. Of course, it sounds like you're trying to do something a bit unethical to bypass some of the fees on a coffee shop wireless connection... if you don't want to pay the fees there, the simpler (and ethical) solution is to go somewhere else, where the wireless is free.

Is there a performance difference between GPT and MBR? If GPT is better, I do not mind formatting the drive with it.

I read through this, and it looks like the problem was fixed in a BIOS update, which I plan to do. However, it also seems like Intel Rapid Start is not even worth it in the first place, as sleep consumes almost no power at all.

Need to add MAC address to router

Any ideas on when you get an error message and how I remove the ACL (access control list)
Try to setup the extender on the same room where the router is installed.
- If MAC Access list of MAC Filtering is enabled on the router, make sure to add the MAC address of the extender.
- Try to turn off and turn on all of your devices to refresh the network.

Can we do MAC Address based routing in ASA5540

I have a network setup where two servers from inside need to communicate with a remote network via 2 VPN gateways. The destinations are same.
However, the chalange is each server need to follow it's own VPN gateway. Since i can't configure PBR (policy based routing) in ASA, can i configure something like MAC Address based routing. I can't use destination based routing since the remote network are reachable from the both VPN Gateways.
Advise needed.
Thanks in advance.

Hi
I am not shure i follow you correct here.
You want 2 servers to speak to the same network but over two different vpn units ?
If this is so then this could work
Just set the route to the other network on server 1 to the vpn gate 1
and route the other network from server 2 to the vpngate 2.
in windows the command is route add.
good luck

Finding OLD MAC address through Router.

Sir,
I lost my laptop (Dell Inspiron 5521 15r) and only have its box which contains serial number 6CRC9W1 , order number 920181961 and etc but dont have MAC address. I asked dell about that but they are not helping me to get mac. Please tell me if there is any
way to get old mac addresses through router to which my laptop was connected. Thanks.

You can't. There is no way to know what the MAC was.
The MAC is tied to the network adapter, not the Laptop, and hence not the Service Tag. Since the Laptop probably had a wired adapter and a wireless adapter,...there would have been two different MACs.
What good would it be even if you knew what it was?

HP C7200 printer/scanner not working with Mac after new router installed.

I recently had my DSL modem go out and replaced it with a combo modem/wifi router. Since the install, my mac can't detect my printer. If I install it via the printer's IP, it'll detect ink levels for a day or two, but still won't print, and won't even detect the scanner. It says the printer is off-line when I try to print. I've rebooted everything, reset the printing system, downloaded updates, and downloaded the latest HP software. Nothing helps. So much for "just works".
My little Windows 7 computer was totally trouble-free after I reinstalled the printer.

If the printer does support Bonjour and it does not appear in the Default Add Printer view then I would say that the Mac is set to a different subnet to the printer (and the Win7 PC). This could also explain why you can add the printer via IP but it won't print.
If the Mac is definitely on the same IP subnet as the printer then check you don't have an application running that could block Bonjour.
With regards to IP queues, ensure you select HP Jetdirect rather than the default of IPP (Win7 will be using Jetdirect which is known as Port 9100). Also, some drivers cannot be used with network connections. If the printer supports Postscript then try a Generic Postscript printer to test. If it doesn't support PS but supports PCL then there is a Generic PCL Laser driver you would try.

Can't connect 2nd mac to wireless router

Hello,
I have a macbook pro set up with airport extreme which runs to my d-link wireless router which is connected to an external modem. I want to set up my second mac to do the same. Do I need to connect it to the network of the first mac? Every time I try I get error message. Or, do I set up an independant network for the second mac, if so how? I can't seem to get anywhere with this.
thanx

Hello kagamushu. Welcome to the Apple Discussions!
Just so I understand your network configuration, is it something like the following?
Cable modem > (Ethernet cable) > D-Link Wireless Router > (wireless) > MacBook Pro
If so, then you only need to configure the AirPort Extreme card on your second Mac to access the D-Link wirelessly.

Advice on Fixing/Setting Up Mac Server behind Router

I would like advice on how to setup/fix a Mac Snow Leopard (10.6.8) server running on an Xserve. The server is only used to to host network accounts / act as a remote drive for a Mac-based laboratory. It is not a mail server, web server, etc. The goal is to enable (i.e., force) students to keep all of their documents on the server while accessing them easily from any computer, ideally from any point in the world.
The current setup is:
Linksys router (192.168.1.1) connects WAN (address WWW.WW.WWW.WWW) to LAN with both DMZ and local DNS pointing to server address (192.168.1.55)
Snow leopard server at 192.168.1.55
Client macs and pcs with various local addresses 192.168.1.XXX
From the LAN side, this setup works well in that all of the client Macs (from PowerPCs running 10.5 to brand new machines running 10.8.4) have no problem accessing their network accounts. They can also access the outside world seamlessly. The server can be administered using Screen Sharing from client machines running recent versions of Mac OS (e.g., 10.8.4)
From WAN side, some things work but others don't:
          – Macs can access the server using AFP://WWW.WW.WWW.WWW, although VPN
                    needs to be running if we are off-campus
          – Macs CANNOT login to the Network Account Server when outside the LAN
                     If I go to "Users & Groups", "Login Options" and enter the server address
                    WWW.WW.WWW.WWW, I get unable to add server with a "Connection
                    failed to the directory server (2100) error message
          – I can no longer login to the server using Screen Sharing. (This worked a few months ago,
                    so I am not sure why this is failing.)
          – I worry that opening a DMZ to the server is unnecessary from a security standpoint, and
                    I would be better with port forwarding specific ports (but which ones?)
I am open to new configurations if necessary, but I suspect this is something straightforward. I am also happy to RTFM for either the server or the router, but I'd like some guidance as to what is feasible/preferred. Specifically, I would particularly like students to be able to login to the Network Account Server from outside the LAN.
The server does not do anything else (e.g., mail, web hosting).
Although we do have an IT support group in-house, their opinion seems to be that computers are security risks that should not fall into the hands of users. The mere mention of Apple products sets off a rant.
Thank you for your advice and suggestions.

I usually use either telnet (non-SSL/TLS ports) or openssl s_client (SSL/TLS ports) or maybe nc (for scanning ranges of TCP and UDP ports) to check access to specific ports from the command line, though it's very simple to run a port scan via Network Utility for this case. Launch that remotely, and see what your client can see.
Here is a list of the ports used by Apple (TS1629)   For Open Directory, you'll need at least TCP 389 or preferably 636 punched through your gateway and your local firewall, if you're not VPN'ing in.   If you're using your own DNS, you'll need TCP port 53 open (and this is mildly hazardous to your bandwidth, as more than a few folks are using DNS servers as part of DDoS attacks; they'll spoof queries and cause your DNS servers to send a reply at somebody else as part of the DDoS. The DNS servers really need to be locked down against this dreck.)
You may also need to aim your client's DNS explicitly at your own DNS server, if you're using a private domain and a private IP address space; if your servers don't have public IP addresses and public names.
Personally, I generally wouldn't expose the Open Directory ports to the 'net, or most anything else for that matter.   I'd usually VPN into the network, and "DMZ" the web-facing stuff where I can. Too much weird cruft is hitting the firewalls I'm monitoring, undoubtedly looking for weaknesses and vulnerabilities. Using the VPN services isn't a panacea, but does mean your traffic is hidden from most monitoring, your servers' ports and services are relatively protected, your DNS services are your own, and your exposure is largely limited to the VPN server access.
For the remote clients, I'd use Portable Home Directory for the wandering devices, or straight OD via VPN.

Mac Mini vs router + server

Hi,
I'm doing some research about the benefits or the Mac Mini with server.
What im aiming for is buying a Mac mini, install OS X Server on it. Connect it directly to the modem and use the Mac mini as a wifi router with built in server options. Integrate it with a firewall and VPN with my devices.
Id like to have some opinion from the hardcore apple users.
Is the wireless card strong enough to compete with a router?
Would the security a router provides be stronger and safer than a server with additional firewall and antivirus software?
Is it possible to tunnel my VPN connection from my iDevices from outside the local network (like 4LTE, 3G, Wifi at a friends house) to my VPN server at home, continued by tunneling my VPN from the server at home (Mac Mini) to my paid VPN Server (company)
Would it be possible to connect with my iDevices to my Mac Mini and use it as a regular computer, even outside of the home network?
I assume that I can externally expand the storage capacity by plugging in an external HDD through USB or Thunderbolt, is this correct?
Can I setup Time Machine on the server to save backups from my MacBooks?
I want to setup my own cloud so I have all my photos, documents and videos in one place, compared to limited storage (unless paid) on Cloud companies. Is it possible to setup my iDevices so they store new pictures and videos in my cloud at home, instead of the iCloud Dive space
What I would like to accomplish with this is creating a single device that provides several purposes related with my iDevices, in and outside it's network.
Including:
Serve as a Wifi router to provide the SSID
VPN service (within and from outside the SSID)
Cloud Storage available to my iDevices (within and from outside the SSID)
Time Machine
Is all of this realistic? What are the downsides of setting it up like this, vs a router with a server connected to it.
Thanks in advance
Mark

I'll bite.
I will preface this by saying that I am not a fan of OS X as a NAT device. Apple removed all easy configuration back with the release of 10.7. While it still can be done, you really must have a passion for tinkering to make it work. Now, there is IceFloor. If you are considering using the Mac as the NAT device, then IceFloor can ease the pain of configuration. That being said, I still believe that it is best to isolate and separate your devices into distinct roles. A firewall is designed to be a firewall. It does that job and does it solely well. OS X Server is a general purpose server. It is capable of many things but it does not necessarily excel at being a NAT appliance. Also, firewalls are generally easier to setup and configure than OS X Server when considering NAT roles and policies.
All that being said, OS X Server is a capable and very affordable solution that works exceptionally well for all Apple environments.
Before continuing, I should point out that you should investigate your residential ISP's policies regarding hosting services. If you are in the US, there are many ISPs that block http and smtp on residential services. Some block additional ports. Plus, if you have a dynamic service then you likely should be looking at dynamic DNS to ensure that you can always reach your server. If you have a dynamic service, this is all the more reason to put OS X Server behind a firewall appliance. OS X, especially for services like Open Directory, Profile Manager, and others, really only work properly when the server has a fixed IP address. If this is not possible on primary route connection, you will struggle with certain services. Placing the device on a LAN and allowing a firewall to handle everything else is a much better solution.
1: Is the wireless card strong enough to compete with a router?
Get a $99 airport express. You will be happier.
2: Would the security a router provides be stronger and safer than a server with additional firewall and antivirus software?
This is arguing between 6 in one hand and a half dozen in the other. Two identically configured solutions result in the same level of security. Or lack thereof. The nice part about a firewall is that it assumes everything is bad unless you explicitly allow it. With OS X, it generally thinks everything is good unless you explicitly deny it. (this is a gross simplification of the situation so you weigh your options) A firewall appliance will likely provide additional services that are easy to configure and also provide more logging and reporting regarding what is happening. Again, I am partial to the firewall.
3: Is it possible to tunnel my VPN connection from my iDevices from outside the local network (like 4LTE, 3G, Wifi at a friends house) to my VPN server at home, continued by tunneling my VPN from the server at home (Mac Mini) to my paid VPN Server (company)
So, you want to be out of your house, create a VPN into your home network, and then be able to traverse to your office? Why not connect direct to the office? How does routing through your home benefit the situation? Regardless, anything is possible. But, the tunnel from your home to the office would need to be built and persistent. Thus, you can remote into your home network. Let's say your home network is 10.0.20.0/24 and your office is 172.16.0.1/24. Your home would build a tunnel to the office. Then the VPN service would advertise the 172.16.0.1/24 route (as well as the 10.0.20.0/24 network) to the client devices, allowing them to access resources on both networks. Then you can request resources on your company network because the route will be provided by the VPN connection.
4: Would it be possible to connect with my iDevices to my Mac Mini and use it as a regular computer, even outside of the home network?
This is another one of my dislikes. Everything has a role and a purpose. Your server is a server, not a workstations. Workstations get rebooted, generally are updated more frequently, run various software and perform varied tasks. Servers have a narrower purpose. I am not a fan of using a server as a workstation. This gets particularly muddy of you are doing file services or need services than must loop back to the server itself. Can you use the server as a workstation? Sure, what is stopping you. Should you? In my opinion, no. Let a Firewall be a firewall. Let a server be a server. Let a workstation be a workstation. Together, they will live in harmony.
5: I assume that I can externally expand the storage capacity by plugging in an external HDD through USB or Thunderbolt, is this correct?
Yes. Thunderbolt is fast. USB 3 is not terrible. Stay away from Firewire at this point. Get something that supports RAID. Remember, RAID is not backup. All it does is provide drive level redundancy.
6: Can I setup Time Machine on the server to save backups from my MacBooks?
Yes. OS X Server provides Time Machine server. Figure out what you want to backup (data only or the whole drive) and then calculate a capacity requirement. While not as critical as in the past, I still prefer isolating Time Machine backup volumes. I tend not to storage any other data there.
7: I want to setup my own cloud so I have all my photos, documents and videos in one place, compared to limited storage (unless paid) on Cloud companies. Is it possible to setup my iDevices so they store new pictures and videos in my cloud at home, instead of the iCloud Dive space
Hmm. So, ah. No. Yes. Well not really. Not easy like iCloud. That is integrated and generally "just works." There is nothing stopping you from manually storing all your content in this location and then sharing it out. But there is no way to redirect an image from your phone to magically appear on your own server. Unless you are using photo stream and you have iPhoto set up on the server. But then we get back to the workstation vs server argument I just had with myself and around I go in a circle. You can create your own storage. But there is effort here. You have WebDAV, Portfolio/Cumulus, and other services and solutions.
So to wrap up...
Serve as a Wifi router to provide the SSID
VPN service (within and from outside the SSID)
Cloud Storage available to my iDevices (within and from outside the SSID)
Time Machine
Using the internal WiFi will only frustrate you. Get an access point and you will get better coverage, better control, and more features. OS X supports two VPN types. PPTP and L2TP. Both will work through a NAT. Both are natively supported on OS X and iOS. Building your own Cloud is the most daunting and vague area. And Time Machine is cake.
Is all of this realistic? What are the downsides of setting it up like this, vs a router with a server connected to it.
Is building a server sitting on a LAN with a firewall realistic? It is done everyday and nearly every network is doing the same thing. All of the above is my take on the topic but I focus on businesses and organizations. These types of setups get a firewall. Then the server is protected behind an umbrella of protection. If you go the mini alone route, you have lower cost by higher difficulty. If you get the individual pieces then you have higher cost but simpler setup and management.
Hope this helps. Once again, too much information. Had a moment of quiet.

New Mac Mini Tiscali Router HELP!!!

Hi
My Dad has just bought his first Mac - a Mac Mini, presumably running Tiger. He is with Tiscali and had a USB modem (Sagem), but went to buy an ethernet adaptor today and the guy in the shop told him it was an old modem and sold him this new Router - an Edimax AR-7084gA. Consequently, any support I could find for Tiscali is now now good as it was concerning the Sagem modem. My Dad's getting very frustrated and I've tried to get him connected, but I'm doing it by phone as he lives miles away and I'm at work and I'm about to cry!!! I feel somewhat responsible as I told him to buy a Mac!
Please can someone tell me what to tell him to do over the phone - even the most obvious stuff. In the Network bit, he's selected the 'Built in Ethernet' option and in TCP/IP he's selected the Using DHCP etc and all the IP addresses and router things have come up, but he can't get any further. Are we doing something really stupid? Do we have to put in phone numbers or anything? The install disc for the router doesn't seem to work but I don't think he needs to do that anyway, as it's obviously seeing the router. It's really hard for me because I'm using an older OS than him and my windows don't come up with the same things.
I've used Macs for years and have set them all up in our office, but it's always been really easy.
Please, please help - no matter how obvious you think you're being, I'm sure it will help.

I would support the move away from the USB modem, but the new one needs some setting up. I just checked and you might like to look at this page, if you have not already done so.
I am pretty certain that all of these modem/routers have a configuration page hard wired into the device and this needs to be accessed using a browser. It may also be a good idea to try with an Ethernet cable before the WiFi as this is one element out of the equation.
Check with the manual, but the access to the configuration page is probably either at 10.0.0.2 (that is all that you need to put in the browser URL space) or at a number beginning with 192..
The 10 series or the 192 series are healthy: you are on the way. A series beginning 168 means that the IP number is self-assigned.
What you have here, "Built in Ethernet' option and in TCP/IP he's selected the Using DHCP etc and all the IP addresses and router things have come up, but he can't get any further" is right.
But it may be that he is not connected to the system without account details being entered: the method may depend on the particular IP.
You may also need DNS numbers for his connection.

Connecting two Macs to one router

I just ordered a new iMac and would like to connect it and my old computer (eMac) to one router so that they share the same network. Is this possible? If so,
Could you explain how to do this.

Yes it should be easy if all devices have wifi. The iMac will have, hopefully the router has, but does the eMac? Do eMac's have wifi built in?
If the router is wifi it'll have a wifi password, normally WPA, WPA/2 or WEP, either on the documentation or on a sticker on the bottom of the router. Turn wifi on on the Macs and they should see the network, type the password when prompted and they should connect.
If the eMac doesn't have wifi you could connect to the router via an ethernet cable and it should be seen on the network.

While using mac as wireless router ; How to make Mac sleep?

Hi all.
I set up my macbook to act as a wireless router [sharing it's wireless signal, via the "Sharing" settings in System Preferences]
using this guide
http://www.macinstruct.com/node/118
I am wondering how to make my mac sleep while this wireless-sharing setting is enabled?
Since I have enabled this setting, the mac will not sleep, however, the mac will sleep when I disable it.
I am also wondering ; [if it is possible to make the mac sleep while this setting is enabled], can I still use the mac as a wireless router even while it is asleep?
Or does it need to be awake to function as a router?
Thanks very much in advance for any help!

Thank you very much everybody for your answers.
Dominic23
and
BobTheFisherman
Yes, I kind of thought what you are saying would be the case.
It makes "sense" that when the computer is asleep, so are all it's functions,
but I *WISH* there was an option to keep the airport functioning even while the computer is asleep.
Bob, I don't think having the OPTION to leave the airport on while mac sleeps would defeat the power-saving feature of the computer (:
I know the "best" way to share wifi is with a router, but for me, a router just another piece of plastic I don't need. All I need to do is share wifi in a small space [my room] from my mac to my iPad and ipod touch.
I like to use my ipad as a reader, and when I am reading, I may be sitting down for many hours just reading from the ipad. It doesn't make sense to leave the mac running during these long periods just for a wireless signal, so I may sadly buy a router ):
Anyway, I get what you are all saying, and thank you for telling me the current limits of this function.
Cheers! (:

Unable to read MAC address of router at login

I'm using the following bash function to get the MAC address of the current router when logging in. The script works when I run it after logging in but doesn't work from my login hook (running as root). The script fails even after sleeping for 30 seconds prior to running. I know the interface is up because my mail client is finished checking mail by the time the script pings the router runs the arp command. I could run it as a cron job, but I'd like to understand why it fails during login.

Ping problem in the neighborhood and Msan can see the mac address of router

Hi everyone
i have a router 1941/K9 with card EHWIC-4SHDSL-EA ,i have configure this card in my router , the problem is I can not ping the ip @ Neighbourhood and the MSAN can't also see the mac-address of the router do you notice that the interface in the MSAN and in the router is UP / UP
anybody help me

Hi,
An ethernet interface will be always up/up and it goes down only if there is problem between the given port and the connected one. The issue can be anywhere else in the middle.

Mac pro as router, should i use INTERNAL airport or EXPRESS for wireless

hello
i want to set up my macpro as a simple server, sharing internet wirelessly and providing storage for TM backups and media files. i also want to access it remotely via Back To My Mac when on the road. i have an airport express that i bought for my stereo to receive airtunes, but am prepared to use it if i will get a better wireless signal by using it over the macpro's internal airport card.
is the card inside the macpro ultimately the same piece of hardware as in the express, or is the express going to handle the task more effectively?
cheers

Although the wireless properties may be pretty similar, the Mac Pro sharing the Internet connection is not as efficient nor as configurable as a dedicated router like the AirPort Express (AX).
For example, using the Mac Pro in this way you can not forward/map ports from the Internet to devices on your LAN.
