Query on SR520-ADSL and using FE ports for WAN

Hi all,
Apologies for a noob type question here but I am hoping to save myself a junk of money:
I currently have a Cisco SR520-ADSL router in place utilising my current ADSL2+ Broadband connection.
The router is using a /29 Public address range on the ATM interface and on one of the FE ports to a firewall on the same subnet, which does the NAT to the PCs etc.
Internet <> SR520 (Public) <> Firewall (Public) <> LAN/PCs (Private/NAT)
This is all working fine but we are looking to upgrade our WAN link to a corporate Fibre link.
My ISP has given me new IP addresses, including a seperate WAN IP Subnet to my LAN IP Subnet, but all are still public.
e.g. (Addresses Just for example purposes)
WAN = 195.1.1.1 /30
My Router IP = 195.1.1.2
ISP Gateway = 195.1.1.1
LAN IP = 190.1.1.1 /29
So my question is simply this: Can I utilise my SR520 to route the two networks, using two of the FE ports and ignore the ATM (ADSL) port?
If so then I don't need to invest in a 1841 or similar and, for now, this will save me money.
I am just not sure if the useability of the 4 FE ports on the SR520 is reduced in any way when compared to a 1841 or similar?

Hi Chris,
Sure, the port itself is layer 2 only, but there is no reason why you couldn't assign that to a dedicated layer 3 vlan interface.
eg:
conf t
vlan 32
name WAN
exit
interface fast 1
switchport access vlan 32
exit
interface vlan 32
ip address 10.10.10.10 255.255.255.0
The SR520 supports 4 VLANs, you can use the show vlan-switch command to see what is already configured.
As I mentioned previously, there may be certain limitations to using this approach, but it may be sufficient for many scenarios.
Also, just to repeat for others reading this thread, while possible, this is not a specifically supported configuration for the SR520 series routers.
Regards,
Andy

Because line-in has been removed.
It does allow for an Apple headset with mic., but I don't know if it would work with third-party ones.
You'll need to use a Griffin iMic or similar to use line-in via a USB port.
The same goes for the 15" retina, the newest MBA and the new iMac (whenever it finally arrives).

Can time capsule be connected wirelessly and still use ethernet ports for other devices?

can time capsule be connected wirelessly and still use ethernet ports for other devices? we have it connected wirelessly but devices connected to the ethernet ports are not working.

Not as an additional router.. the TC will be plugged into the main router via ethernet (or ethernet equivalent)..
Then the TC is setup in bridge mode. It will simply act as a Switch and HDD.
The wireless can be setup in a number of ways.
From your convenience point of view use it in roaming network mode..
you simply give the TC the same Wireless Name as the existing routers SSID.
Same security setting and password. WPA2 Personal = WPA2 AES which is the best.
But they both use different wireless channels.. normally if you leave the TC on auto it will work fine, but I prefer to control the network.. so set the main router to say 1 and the TC to 11.
You can also use a completely different wireless name etc.. that is up to you. It is still a single flat network and the only thing that is important is only having one router.

Using Appliance Ports for NAS

Using Appliance Ports for NAS
Hey all connecting a NAS to UCS. Would like to plug in directly to FI’s using the Appliance Port option.
Are the steps basically
Turn on Ports use as Appliance Ports
Make PIN Group through Appliance Ports (this will only be one port per FI, I am guess Port-Channels can be used if NAS supports that?)
Make VLAN internal to UCS
Make vNIC Template and use newly created VLAN and PIN Group
Boom!
Right?
Thanks!
Craig

I have made port 20 on each 6120 an Appliance Ports.
Each port is assigned to a VLAN made under the Appliances tab.
Cannot seem to make a PIN group using these Appliance ports. They are not a option.
Is there something I am missing?
Thanks!

How can i write a vi in using parallel port for digital inputs

Dear all,
i am a beginner user of LabVIEW and i want to write a vi in using parallel port for digital I/O. After reading the article "Using the Parallel Port in LabVIEW
" and download the parallel.zip, i know how to write the vi for output, but i still don't know how to write the input one.i've try to use a Inport.vi to test, but nothing change when i set pin2-9 to high. (my computer:win2K & LabVIEW 6.1)
Can anybody teach me how to write it?
Can anyone write the vi for me too?
Thanks all!
p.s.i've already install the "accessHW.exe"

Are you using VISA or the accessHW VIs? You may need to goto the bios and set the parallel port to run in spp mode or standard mode. This is the simpliest configuration and where you should start.
As far as writing the VI goes, just copy the diagram out of the tutorial you mentioned.

Where can i find the "use audio port for" button?

I am a Dj and am trying to record. All instructions I have seen, it says to plug my mixer into the line-in input and go to system preferences>sound>input, then change the "use audio port for" option to "sound input". I am not able to do find the "use audio port for" drop down menu, any help??? I have a MacBook Pro that is about six months old and I am running OS X 10 9 4.

Installig and using Crystal Report for reporting on BW

Dear Experts
We are working on BW 7.00 and do't have BO(Business Objects) . Now we wnt to install and Use crystal Report for reporting purpose. Pl. let me know whether Crystal reports can be used to extact data from BW Query or We need to have BO in order to Use Crystal Report.
Thanks in advance
Dinesh Sharma

Hello Dinesh,
first of all Crystal Reports is not a extraction tool - it is a reporting tool - which is a huge difference.
In regards to products you do need Crystal Reports, SAP Integration Kit, and SAP BusinessObjects Edge or SAP BusinessObjects Enterprise.

Mini-PCIe port for WAN on X120e other uses

Hi, I ordered a X120e without the WAN conectivity option so it came without the card but i do have that mini-PCIe available, is it possible to use that port for something else? I wanted to put a second wifi card for penetration testing and research... or even some solid storage card in there.
htp://orvtech.com/?s=lenovo
Solved!
Go to Solution.

Well, unless you hack the BIOS to white-list whatever wireless card you install, it'll be a moot point. Also, you'd need to find a pcie ssd with an onboard controller that advertises itself as a drive controller, of which none of the available ones I know of does. So, in conclusion, unless an engineer comes out and says it can support more, odds are we can't use it for much anything outside of Lenovo wireless cards.

Creating a Master virtual hard disk and using the same for all other VM's

Hi,
We would like to create a master virtual hard disk and use the same for all other VM's. Can we do that ?
my requirements :
1) create 10 VM's
2) first create a master virtual hard disk with win OS and use the same to create the 10 VM's.
3) After creating the VM's change the HDD size.
              -- if i have created master virtual disk with 500GB , and use the same for creating a virtual machine. can we change the HDD size to 1TB ?
After creating the VM's ,i will change the system names and activate the windows accordingly.
Will there be any implications ,if we can/will do like this.
Thanks.

Hi Suren424,
I think Using Differencing Disks may cover your needs .
Please refer to following setps:
   "Create the Parent Virtual Machine Configuration and Virtual Hard Disk
    Install the Operating System, updates, and common software
    Generalize the installation
    Prepare the parent virtual hard disk
    Create the differencing disks
    Create virtual machines that use the differencing disks
For details please refer to follwing link:

Is there a way to create, store and use preset messages for use with "Messages". I often have a recurrinig message to send, after a repeating event, and need to enter the same short message each time. It would be nice to have this short message stored and selectable so that I do not need to enter each time.

Can we assign 2 IPs for a SCCM 2012 primary site server and use 1 IP for communicating with its 2 DPs and 2nd one for communicating with its upper hierarchy CAS which is in a different .Domain

Hi,
Can we assign 2 IPs for a SCCM 2012 primary site server and use 1 Ip for communicating with its 2 DPs and 2nd one for communicating with its upper hierarchy CAS . ?
Scenario: We are building 1 SCCM 2012 primary site and 2 DPs in one domain . In future this will attach to a CAS server which is in different domain. Can we assign 2 IPs in Primary site server , one IP will use to communicate with its 2 DPs and second
IP for communicating with the CAS server which is in a different domain.?
Details:
1)Server : Windows 2012 R2 Std , VM environment .2) SCCM : SCCM 2012 R2 .3)SQL: SQL 2012 Std
Thanks
Rajesh Vasudevan

First, it's not possible. You cannot attach a primary site to an existing CAS.
Primary sites in 2012 are *not* the same as primary sites in 2007 and a CAS is 2012 is completely different from a central primary site in 2007.
CASes cannot manage clients. Also, primary sites are *not* used for delegation in 2012. As Torsten points out, multiple primary sites are used for scale-out (in terms of client count) only. Placing primary sites for different organizational units provides
no functional differences but does add complexity, latency, and additional failure points.
Thus, as the others have pointed out, your premise for doing this is completely incorrect. What are your actual business goals?
As for the IP Addressing, that depends upon your networking infrastructure. There is no way to configure ConfigMgr to use different interfaces for different types of traffic. You could potentially manipulate the routing tables in Windows but that's asking
for trouble IMO.

Not directly; OE is not supported by iTunes. You need full Outlook. Address Book in later versions of Windows is supported.
