How to do a NAT to multiple MACs via the same public IP

Heay y'all,
I have multiple MACs that I need to admin via the same public IP.
I'm trying to activate the NAT function on my airport 802.11n, but I can only register 1 internal IP address for the same port number.
Example:
public UDP port: 3283, 5900
public TCP port: 3283, 5900
Private IP Address: 10.0.1.201
Private UDP port: 3283, 5900
Private TCP port: 3283, 5900
Now if I try to do the same thing for another private address, I get a a conflict... (The Port mapping entry you have entered already exists.)
What I find wired is that:
a) why the private address starts at xxx.xxx.xxx.201
b) why can't I apply the same rule for multiple IPs (e.g. xxx.xxx.xxx.202 and xxx.xxx.xxx.203)
c) I have also, an airport 802.11g and I could configure the NAT table as I wanted.
Am I missing something?
Are three any wild-cards that would cover all internal IP addresses?
PS! I edited my ".baseconfig" file via "textedit" and added a additional private IP address, in the NAT section... I have not gotten any errors, when I load the file in to the base station. but then again I can't edit the IP field via the airport admin tool, and I have not been able to test this workaround.
looking forward to you comments.

Hi guys,
Thanks for the help....
I think i found an alternative solution...
I'll try useing a dedicated internal IP address for my adminwork... then I'll get the user to change from the DHCP allocated IP address to the dedicated one... this way same ports and IP address used for all of the machines.
I'll try this method... if it does not work then I have to use your suggestions... but thanks for your help and response.

How can I get rid of multiple pictures at the same time?

how can I get rid of multiple pictures at the same time?

Adobe Bridge, lightroom and your file browser (windows explorer or Mac Finder) can select multiple pictures at once and then delete. If you are looking for more than that for information, you will need to be more specific at what your doing, what OS you have, and version of software your using. If necessary post screen shots so we can see what your doing. The more information we have the more detailed of an explaination can can give back to you.

Can i back up multiple macs to the same hard drive

can i back up multiple macs to the same hard drive

Yes, you simply share the drive to the network.. in whatever way that is possible as you have given us no info.. over the network TM will create sparsebundles.. locally it can produce a straight backup ..

How would I go about adding multiple rectangles using the same lines of code?

How would I go about adding multiple rectangles using the same lines of code? I would prefer to just run through a set of code every time I need a polygon. If I just have to create multiple polygon adding statements that's fine but I'd prefer just 1.

>>How would I go about adding multiple rectangles using the same lines of code?
You could create a method that creates and returns x number of Rectangle elements:
public IEnumerable<Rectangle> CreateRectangles(int numberOfRectsToCreate)
for (int i = 0; i < numberOfRectsToCreate; ++i)
Rectangle rect = new Rectangle();
rect.Fill = Brushes.Blue;
rect.Width = 100;
rect.Height = 100;
yield return rect;
..and then call this method from anywhere in your code:
IEnumerable<Rectangle> rects = CreateRectangles(5);
foreach (Rectangle rect in rects)
//add to StackPanel or do whatever with the Rectangle elements:
yourStackPanel.Children.Add(rect);
>>If I just have to create multiple polygon adding statements that's fine but I'd prefer just 1.
When adding Point objects to a Polygon you can only add one per call to the Add method but you could call the Add method inside a loop, e.g:
for(int i = 0; i < 10; ++i)
//add to StackPanel or do whatever with the Rectangle elements:
Polygon p = new Polygon();
p.Points.Add(new Point());

ARD over internet to multiple macs using the same connection

Hi, I know the topic has been covered to enable ARD over the net, however all the solutions I see require port forwarding which in essence makes only one computer using the internet connection available, how do you make it so multiple macs can use the one internet connection to send/receive ARD requests? is there a way to change the port ARD uses on individual macs and then forward the ports ? or do I have to go down the VPN path ? or is there a better solution for this kind of setup, thanks Ash

Precisely.
Cheers, Joel
\[ Note, the reason I didn't use 5900 and 5901 was for clarity to make it obvious that they are arbitrary choices on the external side, but also because sometimes using 5901+ gets confusing. Depending on your VNC server software, which port on the internal side that you choose to use between 5900-5920 actually means something (resolution, color depth, etc) to the server software. If you can keep it all straight in your head though, and point them all to the right internal port (5900 usually), no harm in it. If you don't mind adding some awful "security through obscurity," you probably shouldn't have VNC service open to the internet on 5900 anyway. Either way, you should also probably limit connections to those internal machines now that they are "directly reachable" from the 'net. In your firewall they should both have default-deny policies for incoming requests unless they're from your known-safe external addresses.]

Another port question - multiple Macs behind the same firewall

I've searched for this issue, but I can't seem to find a topic directly on point. I know how to forward the right points for this to work, but...
I'm coming from outside the network, and I need to control multiple machines that are behind the same firewall. I can't forward a port to more than one machine. How do I control all these machines?

To be able to connect to a workstation from outside it's network, the ports that ARD uses must be open on both ends of the connection. ARD uses ports 3293 and 5900 so those must be open.
If your workstations get their addresses from an NAT device rather than being "real", as seems to be the case from your description, the ports also need to be forwarded in the router to the workstation's internal IP address. ARD uses port 3283 for the reporting and updating function, so if your Macs are getting their IP addresses through NAT, since you can only forward a port to a single workstation, you can only get reports, push package/files to etc. for a single workstation.
ARD uses the VNC protocol for observation and control, though, and there are a range of IP addresses for that protocol, starting with 5900. ARD uses 5900 by default, so that port would be forwarded to the first workstation. You would, I believe, need to install VNC servers on the systems (since the ARD client cannot listen on any port other than 5900 while VNC servers can be set for other ports such as 5901, 5902, etc. You would then forward 5901 to the second workstation (and on to 5902, 5903, etc.). You can then use the following information:
Remote Desktop 2: How to specify a port number for a VNC client
to connect.
Hope this helps.

How do I customize firefox for multiple users on the same device?

Sometimes my wife uses my computer to surf the web. I'd like to have it set up so she can have her bookmarks, etc. when she's using it and I can have mine when I'm using it. Is this possible? If so how do I do it?

hello arack, the easiest way would be to create different user accounts for you both on the mac on the level of the operating system: [[How do I share Firefox between people on a computer?]]
or you could use the firefox profile manager to create separate profiles: [[Use the Profile Manager to create and remove Firefox profiles]]

Does uploading iPhoto libraries from multiple Macs with the same photos create duplicates in the new Photos app?

I have 4 Macs and I had the same iPhoto library on each of them. When I chose to turn on the iCloud Photo Library on each of them, each Mac, each one of them uploaded the library to iCloud Photo Library.. Now it appears that I have many duplicates in the new Library. Is it adding each of the 4 libraries to the mix? It's a real problem as I have 25,000 pictures - 70GB in my library. So paused the upload on 2 of the Macs about half way through in case it is creating duplicates, until I get some answers. Any help would sure be appreciated.

I'm in the same boat as well. I'm doing one mac at a time and seeing how it works. Howev the upload is so slow, who knows when it will be done.

How to insert a UUID into multiple tables in the same form

I am trying to insert a UUID into 2 different tables at the
same time ie to let this be created in the form and then insert
this ID into 2 linked tables in a database using Access.
Does anybody have any suggestions on how to accomplish this?
Thanks very much

So you have one form that processes information for two
tables, or do you
have two forms (one for each table - except the UUID)?
If it is one form just run two SQL insert statements. One for
the primary
table, then one for the related table.
If it is two forms run the above two SQL statements then an
update statement
to finish filling the second table.
Or am I completely misunderstanding the issue?

Can multiple Macs access the same firewire volume simultaneously?

I have a firewire drive and hub, and two Mac Minis. I would like to use this hardware to build an Oracle 10g Real Application Cluster (RAC). To do this, both Macs would have to be able to read/write blocks on the same volume on the firewire drive (Oracle prevents collisions). Newer Linux kernels have support for doing this. It seems that the Mac OS X Server 10.3.4 that I am using blocks at the volume level by node. It would seem to preclude my using this hardware unless I devote another machine to being an NFS server for the shared storage. I'm looking for possible kernel tricks to get this to work.
Jeremiah
Mac Mini Mac OS X (10.3.4)

According to Oracle's white paper on RAC:
The type of disk storage used can be network attached storage (NAS), storage area network (SAN), or SCSI disk.
It does go on to say:
Alternatively Oracle supports the use of raw devices and some cluster file systems such as Oracle Cluster File System (OCFS) which is available on Windows, Linux and Solaris
I suppose if Oracle is taking over the raw device, support might be possible, but OCFS is not available for Mac OS X.

How can i use Mail on 2 macs with the same mail address?

Hi,
I have two Macs, connected through WLAN. From each Mac I can use Mail (sending and receiving) with the same mail address. This worked well; on each Mac I have separate files storing the mails (input, sent, trash, …).
Some days ago I had to change the provider. (Perhaps this may be the reason for my problem?) Now both mail systems are connected - in the way that if I put on Mac *1 a mail into the trash it is automatically thrown into the trash on Mac *2.
What is to be done to separate the two systems (i. e. make them independent of each other)?
Hans

It looks like you are using a IMAP mail account, a protocol used by most email providers nowadays. Read -> http://en.wikipedia.org/wiki/Internet_Message_Access_Protocol
The main feature of IMAP is the sync of all the changes you do on your mail account. If you want to keep your mails on one Mac, have a look at this site -> http://kb.mit.edu/confluence/pages/viewpage.action?pageId=3908294

How to create send connectors for multiple sites in the same domain?

Current Scenario:
We have 2 offices, 1 in London and 1 in India. Both are in the same domain and are connected via VPN. Both have their own separate Exchange 2003 server. Each location sends out their mail via the Default SMTP Virtual Server on their exchange server through
their local ISP. There are no Send connectors created currently.
We have now installed an additional Exchange 2010 server with Hub, CAS and Mailbox roles at the London site. Internal mail flow between the sites seems to be working fine.
I believe the Exchange 2010 needs a Send connector to send out mail to the internet. However as soon as we create a Send connector on Exchange 2010, mail from the older 2003 servers at both sites start to flow out from the exchange 2010 server. This is not
optimal for our India site since their outgoing mail now has to flow via the VPN to London and out via the new server.
How can we configure it so that each server sends outgoing mail independently?
Thanks

Hi,
In India site, you can create a SMTP connector which point to the local ISP.
Thanks.

I am totally new to app development. I have to make a simple app( sort of a to-do list). I need this app to work on mac desktops and also on ipads and iphones. I need to know how to make a GUI on a mac.will the same prog. be compatible on all 3 devices?

what will you recommend me to learn first? i am getting acquanited with objective C language(done C++ before). but no experience of gui.

It's possible. Just create a second target of the appropriate type and then change the "Base SDK" build setting. Then make sure to add all the necessary files. If you want to build both at the same time, create an aggregate target. So my mean you have to maintain two targets one for iPhone / iPad and Mac also....... May be it helpful to you......

How to change blending mode on multiple layers at the same time

I'm using CS5. I have a document with about 70 layers. I would like to change the blending mode to "lighten" for each layer. Is there an easy way to do this?

Photoshop doesn't allow multiple layer editing. That's why the styles are grayed out. Only 1 layer at a time.
What version are you talking about?
CS5 definitely let’s one apply a Style to multiple Layers.
rfcommagere, I don’t know how to make it much clearer:
• set the Blending Mode on one Layer
• with that Layer selected create a Style with »Include Layer Blending Options« checked
• select all other Layers that should have that Blending Mode
• click the Style in the Styles Panel

How do I bounce tracks to multiple outputs at the same time

Hi,
I have more or less 30 to 40 stereo audio tracks routed to 4 stereo outputs and want to bounce these tracks in one bounce process, so that I get 4 stereo tracks. How do I do this?
I know the different possibilities as bounce in place, the different export functions and I also could record these tracks in real time to the resulting 4 stereo tracks. But I would prefer bouncing.
Any idea?
