Is an 'external' static IP address required to set up DNS

Hi there
I'm going to be setting up a OSX Server 10.3 machine as an open directory master, to take advantage of single sign-on capabilities.
From what I have read in manuals and in this topic: http://discussions.apple.com/thread.jspa?threadID=977178&tstart=15 , it is necessary to configure the DNS service first. However, the topic talks about having an external IP address for the server, as well as for the internet router.
Is this the only method that will work? The network only has one external IP address as far as I am aware.
Any thoughts greatly appreciated.
Matt

The answer is, it depends.
If you want your server to provide any external services then it will need an external IP address. Now, depending on your network, you may be able to use a single IP address on your router, having it NAT incoming connections via port forwarding - that's a common setup.
The bigger issue is whether you need a static IP address or can live with a dynamic one. A static IP address is required if you're running certain services such as DNS or Mail. Other services might be able to get by with a dynamic IP, depending on what you're doing with them (for example, it's OK to run a personal web site on a dynamic IP address, but you wouldn't want to do that for a corporate web site that gets a lot of traffic.

Change to a "static" IP address impact time capsule backup?

It just hit me that another thing I've done since my last backup is change from the DHCP (?) IP assigning to a static IP address. Also set up some "port forwarding" for a few sites.
Could that be why time capsule is now forever "preparing?" I have added a lot of content but I let it sit for 24 hours with no change in status. I'm wondering if somehow the IP address is screwing this thing up. I don't think so but what do I know? =)
Thx.

I'm not too familiar with FileMaker Pro, but if you like to give static IP addresses to anything you would have to use DHCP Reservations using Airport Utility.
Open Airport Utility, select the Time Capsule device, click Manual Setup, navigate the Internet icon, then the DHCP tab, you'll see DHCP Reservations towards the bottom.

Can I assign Airport Express to static IP Address?

Current setup - Airport Extreme attached to cable modem with 2 hard drives, Airport Express as print server in separate room with USB printer attached (just changed from Linksys with sometimes working NetGear print server). Clients accessing the network: 2 Windows XP, 1 Windows 7, iPads, iPhones, iPods, Apple TV, and sometimes a Mac Book.
The issue is that we don't keep the printing system on at all times (light switch with Express and printer plugged in); We dont't do much printing, and I print to pdf most of the time. As a result, the Express IP address changes every time it's turned on, requiring me to change the port settings on the printer properties before anyone can print. Is there a way to assign a static IP address to the Express so that I don't become tech support every time someone else in the house needs to print something?

Is there a way to assign a static IP address to the Express so that I don't become tech support every time someone else in the house needs to print something?
Yes. The first order of business is to find the AirPort ID for the AirPort Express. You do this by opening AirPort Utility and clicking once on the Express. In the area to the right, jot down the AirPort ID.
Still in AirPort Utility, now click on the AirPort Extreme and click Manual Setup
Click the Internet icon
Click the DHCP tab below the Advanced icon
Look for the DHCP Reservations area and click on the + (plus) button at the bottom
Enter a description, for example AirPort Express
Click the MAC Address button and click Continue
Enter the AirPort ID in the MAC Address box
Assign the IP address you want the Express to use, for example 10.0.1.20
Click Done, then click Apply and the AirPort Extreme will restart
It would be a good idea to power cycle the entire network as follows:
Power everything down...all devices, order is not important
Power up the modem first, then AirPort Extreme, then Express, then devices

DNS and Static IP Address Question on Solaris v10 X86

I�ve recently installed Solaris v10 X86 and have two questions. The system is a Dell E521 with 4GB RAM and 1GB SysKonnect NIC, and internet is provided via a cable modem, that�s plugged into a Netgear router, and the Solaris 10 box is plugged into the Netgear router via a CAT5 ethernet cable.
1. I can connect to my router login page using the following URL:
http://192.168.1.1/start.htm and I can also connect to various web pages such as yahoo, if I first "ping yahoo.com" (on another machine that�s internet enabled) and then plug the web site�s ip address into the Solaris/Mozilla browser. So it appears that I haven�t been successful at pointing the Solaris x86 at a DNS server to resolve the DNS name.
2. I've purchased a commercially available software package and it requires a static ip address for this Solaris x86 server. If the ip address changes, it�ll stop working by design and require that I reacquire the license file. When connecting through this Netgear router, how do I lock this Solaris v10 x86 server into a specific ip address? (the ip address floats presently when cycling my PC�s on/off) presently, and assume the Solaris box will too, usually through an ip range of 192.168.1.<1 through 5>

The NIC is a SysKonnect 9821 1GB Ethernet card. The drivers in Solaris 10 were apparently very old and didn't install drivers or configure/plumb when I installed Solaris 10, so I downloaded the
latest drivers (hard to find!), followed the instructions and got the NIC drivers installed and then plumbed.
My router's ip address appears to be 192.168.1.1 and in one of the articles I've read, there is a recommendation to create a file (touch) within /etc named defaultrouter and enter the router's ip address. I did this, and the file now contains:
192.168.1.1
I also read where another file called resolv.conf needed to be pointed to a DNS server, which in this case, according to my Netgear router, and according to ipconfig/all on another WinBox on the same network, also shows the same 192.168.1.1 address for the DNS, so I created that file too (wasn't there) and it contains:
nameserver 192.168.1.1
There is a host name file called hostname.skge0 and it contains one line:
INTHOST
There is a hosts file, and it contains:
127.0.0.1 localhost loghost homex86
192.168.1.3 INTHOST
There is a netmasks file, and other than the commented out lines, it appears to contain one relevant line:

There is a nsswitch.conf file and other than the commented out lines, it contains:

Finally, I've also seen some advice using the folling command (and I tried it):
"route add default 192.168.1.1" as an alternative method of setting up route table
The only other command I've tried is:
"ifconfig skge0 192.168.1.1 netmask 255.255.255.0 up" but I suspect that was redundant as the plumb command I used to get the NIC functioning earlier probably already provided what was needed.
Finally, on this small network, I ran an ipconfig/all on a Windows based PC, to see what network settings were reported through the wireless connection, and this is an excerpt of that information:

Do I Have To Have A Static IP Address?

I am in the very early planning stages of creating a Server based network for my business. I have several issues which can be solved using a server. As a photographer I keep beating my HD space and will wind up with a RAID system like a Drobo FS. Another issue is uploading images from a shoot to the server which will require configuring a VPN - some have suggested a server domain name then access storage or other areas from the domain. I've basically been told I will need a static IP address to make this whole system work. I talked with my cable ISP and was told I would have to have a Business Account inorder to have a static IP address. Not only is a business account at least 2x the cost of a residential account but the service (speed) is substantially slower than what I have now. My obvious question is whether I have to have a static IP address to make all this work? I have done considerable reading on the whole server issue and while I've found lots of other answers, I cannot find an absolute answer to this question so I'm going to rely on what I've found to be experts. Many thanks for the guidance.

I have found that with most residential broadband providers (at least with cable) your public IP address stays the same unless you change the hardware that is connected directly to the cable modem. So, if you have the same router connected to the cable modem for a year your public IP address has probably been the same for the last year.
Business class solutions suck in that they cost more and aren't usually as fast (unless of course you want to pay even more money) as residential services but they do get a static IP address and they get all ports unblocked. Since your IP shouldn't change as a residential customer unless you switch hardware the only real gain is the port unblocking.
For me, I wanted to be able to host a mail server and web server on my server and in my house. That is the reason I switched to a business class account. I was able to run AFP, iCal, Address Book, and VPN services over the internet on my residential account (because those ports weren't blocked) but because I wanted to run a mail server and web server - and not violate my provider's TOS by running a server on a residential connection - I upgraded to business class.

Port Forwarding and Static IP addresses

Netcomm NB1300 router and Airport Express.
I want to use and old G3 mac running 10.3.9 as a server for HTTP and FTP. The Mac is currently connected via Airport but I can connect it via Ethernet if necessary.
I understand that I will have to activate Port Forwarding on my Router with Ports 21 and 80 to allow external Internet access to the G3. I will also have to configure DHCP Manually for a Static IP address and probably link up with a Free DNS service to maintain reliable access to the G3.
I have other computers on the network, two Macs (Ethernet / 10.3.9 & Airport 10.4.11) and two PC's (one with Vista, one with XP / both on Airport). Only one of the extra Macs is connected via ethernet, the rest are connected via Airport.
Will I have to assign Static IP addresses to all the computers or just the one I want to use as a server?
And also, can anyone tell me about Port Forwarding via Port 22 to give more security from external observation/attacks? I know nothing about this security measure.
Thanks in advance.
Christo.

I am now assuming I will be able to access the 'server' from an external location. Very optimistic! But I can't test that for a couple of days.
Ah, but you've given up too soon! You can access your web server from outside your network real easy: you just need to find an external client you can point back to your site. I like to use the W4C validator to do that. It has the happy side effect of also telling you if your web page markup is valid. So you'd point your browser to the validator page:
http://validator.w3.org/
I like to choose "More Options" and tell it to show the page source. That way I can also verify that it's seeing the page I want it to see.
If I disconnect the iBook from Ethernet, can it still be accessible from an external location if it is connected to the Router via Airport, or do I have do so something like Port Forwarding with my Airport Express as well? Note the iBook can still connect to the Internet via Airport.
It would depend on how your Airport is set up. I think there are a couple of ways to set them up. One is to make the Airport a DHCP server, which would make the wireless network essentially a separate network. In that case, you'd have to forward throught the Airport, too.
My wireless network, though, is set up to bridge, so it's all one network. In that case, all I'd have to do to forward wirelessly to a client would be to set up the forward on the main router.
Being that persons other than myself will be accessing the iBook via FTP, do I give them the user account password of the Mac, or can I set a password in the Router or something else?
Also, when accessing the iBook on my local network using Cyberduck, I can see the entire directory of the iBook's user account. Is there a way to limit access to just one folder, such as the Public folder, or a self-designated folder?
Unfortunately, I don't know anything about setting up FTP. I would suggest that you look into maybe making an account on the iBook specifically for the FTP user and only give out that username and password. You might want to poke around in the Networking and the Web and Unix discussions in the Mac OS X Technologies area. I've seen a number of posts there about setting up FTP, and you might be able to find your answers there.

Point to Static IP address

When I am entering the IP address during the initial setup in Standard Setup do I point it to my static IP address 78.105.171.155 or to the one I set up on my router 192.168.1.69
Because currently it points to 192.168.1.69 and it thinks my DNS name is Bunnymen.config, if I point it to my static one 78.105.171.155 which is pointed to my website address by the name host and RDNS by the internet service provider will it give me a DNS name of Bunnymen.com?

You need to setup whatever IP address your machine will have when it's running.
Ignore completely, for the moment, any NAT address that external users would use to get to your server (via port forwarding in your router). The server knows nothing (and doesn't need to know anything) about that address at this point.
Therefore, if you've setup your router to use port forwarding to forward connections to 192.168.1.69 (which is what I think you're saying), that is the address you configure the server with.

Applying Static Ip Address to server

Could some please help I have been working on this since last friday.
I have a bt business line which they have given me 5 static IP addresses
I have a Netgear Modem Router DGND3700 and a Airport Extreme which I bought last friday.
On my Netgear bt said go to LAN setup and enter my starting IP address and Ending IP address Subnet mask and Hub address which I have done.
I have a Network cable from my netgear to my Airport Extreme WAN port, and I have a Network cable from one of my Ethernet port to my mac mini lion server.
On my server under network I have set it to manual and entered my static ip address subnet and dns which was provided bt bt.
When I open Airport Utility on my Airport Base I have set the Internet to static ip address which it shows green but my internet is not connected.
But when I go to network and go to enter my static ip address I cant as my ip address start with 81.xxx.xx.xxx
I am not sure if I am doing it wrong or Im missing something.
Thank you for taking time to read my post

maybe you forget to put a static DNS ^_^ which is also required if you put an static ip if your DNS is not correct theres no internet even if its light green ^_^
hope it helps

PS Script to Automate NIC Teaming and Configure Static IP Address based off an Existing Physical NIC

Howdy All!
I was recently presented with the challenge of automating the creation and configuration of a NIC Team on Server 2012 and Server 2012 R2.
Condition:
New Team will use static IP Address of an existing NIC (one of two physical NICs to be used in the Team). Each server has more than one NIC.
Our environment is pretty static, in the sense that all our servers use the same subnet mask and DNS server IP Addresses, so I really only had
to worry about the Static IP Address and the Default Gateway.
1. Retrieve NIC IP Address and Default Gateway:
I needed a way to query only the NIC with the correct IP Address settings and create required variables based on that query. For that, I
leveraged WMI. For example purposes, let's say the servers in your environment start with 192. and you know the source physical NIC with desired network configurations follows this scheme. This will retrieve only the network configuration information
for the NIC that has the IP Address that starts with "192." Feel free to replace 192 with whatever octet you use. you can expand the criteria by filling out additional octects... example:
Where-Object
$_.IPAddress
-match'192\.168.' } This would search for NICs with IP Addresses 192.168.xx.xx.
$wmi
= Get-WmiObject
Win32_NetworkAdapterConfiguration
-Filter "IPEnabled = True"
|
Where-Object {
$_.IPAddress
-match '192\.' }
$IPAddress
= $wmi.IpAddress[0]
$DefaultGateway
= $wmi.DefaultIPGateway[0]
2. Create Lbfo TEAM1
This is a straight forward command based off of New-NetLbfoTeam. I used "-Confirm:$false" to suppress prompts.
Our NICs are named “Ethernet” and “Ethernet 2” by default, so I was able to keep –TeamMembers as a static entry.
Also added start-sleep command to give the new Team time to build and come online before moving on to network configurations.
New-NetLbfoTeam
-Name TEAM1
-TeamMembers "Ethernet","Ethernet 2"
-TeamingMode SwitchIndependent
-LoadBalancingAlgorithm
Dynamic -Confirm:$false
# 20 second pause to allow TEAM1 to form and come online.
Start-Sleep
-s 20
3. Configure network settings for interface "TEAM1".
Now it's time to pipe the previous physical NICs configurations to the newly built team. Here is where I will leverage
the variables I created earlier.
There are two separate commands used to fully configure network settings,
New-NetIPAddress : Here is where you assign the IP Address, Subnet Mask, and Default Gateway.
Set-DnsClientServerAddress: Here is where you assign any DNS Servers. In my case, I have 2, just replace x's with your
desired DNS IP Addresses.
New-NetIPAddress
–InterfaceAlias “TEAM1”
–IPAddress $IPAddress
–PrefixLength 24
-DefaultGateway $DefaultGateway
Set-DnsClientServerAddress
-InterfaceAlias “TEAM1”
-ServerAddresses xx.xx.xx.xx, xx.xx.xx.xx
Hope this helps and cheers!

I've done this before, and because of that I've run into something you may find valuable.
Namely two challenges:
There are "n" number of adapters in the server.
Adapters with multiple ports should be labeled in order.
MS only supports making a LBFO Team out of "like speed" adapters.
To solve both of these challenges I standardized the name based on link speed for each adapter before creating hte team. Pretty simple really! FIrst I created to variables to store the 10g and 1g adapters. I went ahead and told it to skip
any "hyper-V" ports for obvious reasons, and sorted by MAC address as servers tend to put all thier onboard NICs in sequentially by MAC:
$All10GAdapters = (Get-NetAdapter |where{$_.LinkSpeed -eq "10 Gbps" -and $_.InterfaceDesription -notmatch 'Hyper-V*'}|sort-object MacAddress)
$All1GAdapters = (Get-NetAdapter |where{$_.LinkSpeed -eq "1 Gbps" -and $_.InterfaceDesription -notmatch 'Hyper-V*'}|sort-object MacAddress)
Sweet ... now that I have my adapters I can rename them into something standardized:
$i=0
$All10GAdapters | ForEach-Object {
Rename-NetAdapter -Name $_.Name -NewName "Ethernet_10g_$i"
$i++
$i = 0
$All1GAdapters | ForEach-Object {
Rename-NetAdapter -Name $_.Name -NewName "Ethernet_1g_$i"
$i++
Once that's done Now i can return to your team command but use a wildcard sense I know the standardized name!
New-NetLbfoTeam -Name TEAM1G -TeamMembers Ethernet_1g_* -TeamingMode SwitchIndependent -LoadBalancingAlgorithm Dynamic -Confirm:$false
New-NetLbfoTeam -Name TEAM10G -TeamMembers Ethernet_10g_* -TeamingMode SwitchIndependent -LoadBalancingAlgorithm Dynamic -Confirm:$false

Convert Autonomous to lightweight AP - Static IP Address

Hi,
I've converted a couple of Autonomous APs to lightweight recently and once they reboot they have a static IP configured on them, which then requires console access to remove the static IP.
Below are the commands I run to convert the AP:
AP#archive tar /xtract ftp://username:password@FTP Server IP/ap1g2-rcvk9w8-tar.152-2.JB3.tar flash:/
AP(config)#boot system flash:/filename
AP#copy run start
Is there something I'm missing in my process which will prevent the AP from having a static IP address when it reboots and loads the lightweight image?
Thanks,

AP#copy run start
Instead of saving the config, you need to delete the config using the command "wr default".

Unable to access internet when static IP address is configured

Hi
I am facing the problem for not getting the internet in AD Server(DC) if configured with static IP address. If we set DHCP it will connect to internet. When I check the IPCONFIG on DHCP settings its showing the external address of the ISP router. Not the
firewall. Suspect there must be a foul play with DNS. Appreceiate your prompt response.
Thanks

Hi
First, Disable ipv6. then run the netsh command to reset IP stuff. Just a warning though,
I think this will only apply to this problem if you are using static IPs.

How to apply Static IP address without disabling data plan

Our Network team does not want to open all ports on a server mobile staff needs to access. We ordered static IP addresses and entered them on the firewall so they can specificall access. Once the IP address is added to the iPad - the data plan is disabled.

I have just tried giving my iPhone's WiFi a static IP address and it did not stop the cellular data from working.
I probably misunderstand your problem.
I presume by a static address you meant the WiFi, was this a company internal IP address or an external one?
There could be differences between the iPhone and the iPad in how it handles this situation, my iPad is WiFi only so I could not test this.
If you get no other suggestions on the forum I suggest a visit to Appe store if possible or a phone call to Apple. If you are not under Apple Care there may be a charge for the telephone support but may save a lot of hassle. The option is to ask your Data plan provider.
Sorry I can offer no other suggestions.

How do I setup my WRT610N router configuration for this situation? My ISP requires that I connect to their website and enter a login and password. Afterwards I have to open a new browser window to surf the net, and leave the original open.

Well you can input the static on your Router... But beside static IP address your ISP required a Username and Password Authentication.... Well i dont think its possibel... May be in this case you can call your ISP and they will change the configuration settings on their Modem.....
As your Router will accept only 1 mode of Authentication,, Static IP or PPPoE or DHCP.

Extreme external static ip

I just got an external static IP from my isp.
All works fine but internet is very very slow.
Anyone has an idea?

Let's double-check a few of your settings using AirPort Utility v5.x.
On the Internet > Internet Connection tab:
Connect Using = Ethernet
Ethernet WAN Port = Automatic (Default)
Connection Sharing = Share a public IP address
On the Internet > TCP/IP tab:
Configure IPv4 = Manually
IP Address = <the static IP address provided by your ISP>
All the other IP addresses on this tab should be the ones provided by your ISP.
Is this the way you are currently configured?

Change to a static IPv4 address and lost IPv6 - SMC D3G and Airport Extreme

I hope someone can help sort out my IPv6 problem. We have a business Internet account with the SMC D3G-CCR gateway and Apple Airport Extreme (the new tall model). While using dynamic addresses and letting the SMC gateway handle DHCP (Airport Extreme in bridge mode) my IPv6 tests all worked (outbound requests worked - I never tried any incoming access to servers). The test site at http://test-ipv6.com said all was good and I could ping6 ipv6.google.com from any inside computer. Due to a new client project requirements, I got a static IP address today. Comcast reconfigured the SMC gateway and I set up the Airport Extreme to handle internal routing and DHCP and port forwarding for a camera and SSH services. All of that IPv4 stuff seems to be working properly. Unfortunately, I can't find a combination of settings that will give me access to outside IPv6 servers anymore. I was hoping to start testing a small Raspberry Pi server using inbound IPv6, but now I can't seem to get anything going with IPv6. The SMC box does have a setting that appears to block incoming IPv6 requests. But I assumed that would be disabled with the static IP configuration. Either way, it shouldn't block my outbound requests so something else must be wrong. Am I missing a setting somewhere? Do I need Comcast to change something else? Do I need a different gateway device?

First, I am assuming that you are trying to administer your AirPort base station for a static IP address using the iOS version of the AirPort Utility ... correct?
If so, then to do so:
Start the AirPort Utility app on the iPad
Select your base station.
Select Edit
Select Internet Connection
Select Static
Enter the appropriate IP address information
Select Done
Sorry, it does not appear that direct input for DNS IP addresses is an available option with this version of the iOS AirPort Utility app. Not sure why this was not included.

Is an 'external' static IP address required to set up DNS
