HA ACS in two different subnets.

Hello,
I have to configure two ACS 1113 ver 4.1 (4) high reliability, in two different places and two different subnets.
An apparatus will have to manage an office, the second the other office, but if one goes down the other takes responsibility for the entire network.
The two subnets are accessible from all devices.
Will be configured both the Tacacs Server on all systems.
The ACS are connected to Active Directory to authenticate users.
My question is, do I create a profile ACS are replicated on the other even though they are on two different subnets? Can I make a HA on two different subnets?
Thank you.

Hi Fabio,
1. Is it a problem that the ACS are connected to two different Active Directory that belongs to the same Domain?
Ans: I do not think so there should be any pbm when they have in the single domain.
2. Is there a particoular configuration to replicate just the profiles that i'm going to create on the Master ACS?
Yes. But its up to you how you want it and what and all you want to send for replication. You have an check box option to select the wanted configurations to be pointed for replication.
Please do rate if the given information helps.

Mac, WRT 54G, Can I access a Brother MFC9320 on two different subnets?

(home use) I have a USB server that I can access my USB printers on two different Subnets and I was wondering if I can do the same on the WRT54G. I use 192.xxx.xxx.x for internet use only and 198.xxx.xxx.x for every thing else, like file sharing, multiplayer games, etc. I just named the "Locations" to either "Internet" or "Games" (with games being used for everything else). With the USB server set to "ZerocConfig" I could access the USB printers on both. I could set the Printer up with a static IP Printer "Location" and then switch locations every time we wanted to print to it but I would like to save a step. It's not that big a deal for me but, having to "Remind" everyone else every time they wanted to print something on it, would get old. Don't want to hook the Brother up to the USB server if I have wireless. It's not the smallest thing in the world to find a place for it anyway.
I guess my other question would be, having the other subnet, is it more secure (from the internet) using it that way or is it just in my mind. I actually have the the family put their computers on a third "Blank" Location (no IP #) when they are just playing games, homework, etc.
Thanks,
Solved!
Go to Solution.

I'm guessing the reason i CAN use the USB printers on both subnets is because of the Keyspan USB server, which is hooked to the router, using it's own version of DHCP, (ZeroConfig)? I guess "ZeroConfig" is an open source type configuration. I use a subnet of 192.xxx.xxx.xxx for Internet browsing and I can print with the USB printers, and I use a subnet of 198.xx.xxx.x for everything else and I can still print from the USB printers with out changing anything else. It uses it's own IP numbers on ZeroConfig I guess and when the server is set to DHCP it uses the routers IP instead as then i can't print on the other subnet.
I guess it's not possible on the router to do it. That's what I was wondering, thanks.....

Hi Sanjeev,
If it is a context based configuration that you are doing then, you would need to configure context on the ASA first, you can refer to this document for it:

ASA5510 RA VPN, ACS assigned address different subnet than inside interface

Currently we have our RA tunnels set up with IP Address pools that are in the same subnet as the ASA inside interface and that works to give the clients connectivity.
I have seen that this is not the best way to go with this and also have seen some config snippets.
But I have not seen exactly how this should be done, and I don't really see anything in the config examples.
For example, If my ASA is 10.10.10.1 and I want to assign each person a specific IP Address in an address pool and I want each group to be in a different subnet:
Eng = 192.168.100.0
Bob = 192.168.100.1
Bill = 192.168.100.2
Sales = 192.168.200.0
Sue = 192.168.200.1
Sam = 192.168.200.2
I have two core switches with the SVIs configured for these subnets.
But, I don't see how the routing is accomplised in the ASA.
Also, I can configure the ACS to give each person an IP Address, but not sure what is needed in the ASA.
Do the pools still need to be configured in the ASA and the ACS hands the client an address that I specify in that pool?

Better to reset an IP pool and reclaim all its IP addresses:

How to map two different subnets to one SSID

Hi Experts ,
we have two offices in same city at different location however we are planning to bring both the office at same location.
Now lets say site A has controller 5508 configured with 24 AP's with 10.10.10.x subnet for internal SSID and Site B which is shifting to Site A campus has different subnet ( 10.10.20.x ) for same SSID.
Site B has no controller since they had connection with H-reap and they were using different subnet for internal SSID ( 10.10.20.x ) .....
Now i need to add their AP's in Site A controller which will be extended wireless LAN however we would like to keep same subnet ( 10.10.20.x ) what Site B has for wireless clients which is really confusing me ....
I have already client subnet for site A with 10.10.10.x /24 subnet and nearly 200 users are already using this wireless client subnet....
How do i add their ( Site B ) subnet / 10.10.20.x with same SSID configured which is globally only one SSID ?
limitations :
I can not create new SSID for site B since same will be broadcasting even in Site A AP's
Is this possible to map one more subnet of site B to existing SSID with already different subnet ( 10.10.10.x ) ?
Your suggestions will be really helpful for me to go ahead and understand in better manner ...

Well first off, you need to bring that subnet over to site a without breaking any routing. Once you do that then sites B subnet will have a different vlan than site A of course. Now with both subnets working in site A, you create a dynamic interface on the WLC for that new subnet. Create an AP group for both sites, you can name it by vlan or by any name you want. Now in the ap group for site A, you define what SSID's you want and map the vlan to that ap groups. Then add sites A AP's to that group. You do this also for site B's AP's and map the SSID to the new subnet you brought over and move the AP's to that group. The APs from site B would have to be setup in local mode not hreap.

Integration of ACS with two different Domain in different forest

Hi
We have two Domain Controllers in two different forests. One forest is X.IN and other is Y. In X.IN forest we have a tree called PPP.IN.
Is it possible to integrate ACS with both PPP.IN and Y? Please confirm ASAP.
Thanks
Ritesh

It is possible in ACS 4.2 to do machine and user authentication over cross forest trusts. See Resolved Caveats here:

URGENT !!! Two physical network interface with two completely different subnets - No bridges - cannot connect both

This is my urgent problem:
I have a physical machine with two physical network interfaces. I have a VMWARE player installed and a virtual machine that must use both cards on two different subnets, one directly public on the router and one intranet inside the company.
How can I just tell one net card to go on that sub and the other on the public sub ? Going crazy. Please help.
Thanks,
P.

Using VMware Player Virtual Network Editor, create a additional bridged VMnet and bind each bridged VMnet to a different physical network adapter... on virtual machine, create a virtual network adapter to each subnet, and bind each virtual network adapter to a different bridged VMnet.
For additional help with virtual network editor, check this KB: VMware KB: Using the Virtual Network Editor in VMware Workstation

ASA 5505: VPN Access to Different Subnets

Hi All-
I'm trying to figure out how to configure our ASA so that remote users can have VPN access to two different subnets (office LAN and phone LAN). Currently, I have 3 VLANs setup -- VLAN 1 (inside), VLAN 2 (outside), VLAN 13 (phone LAN). Essentially, remote users should be able to access their PC (192.168.1.0 /24) and also access the office phone system (192.168.254.0 /24). Is this even possible? Below is the configurations on our ASA,

Hi Jouni-
Yes, with the current configs remote users only have access to the 'inside' LAN (192.168.1.0). The digital PBX on the 'phone' LAN (192.168.254.0) is not reachable through their VPN session.
Per you recommendation, I removed the following configs from my ASA:
global (phones) 20 interface
... removing this configuration didn't make a difference -- I was still able to ping the inside LAN, but not the phone LAN.
global (inside) 10 interface
nat (outside) 10 access-list vpn_nat_inside outside
.... removing these two configurations caused the inside LAN to be unreachable. The phone LAN was not reachable, either. So, I put the '10' configurations back.
The ASDM syslog is showing the following when I try to ping the PBX (192.168.254.250) through the VPN session:
"portmap translation creation failed for icmp src outside:10.0.1.1 dest phones:PBX (type 8, code 0)"
What do you think?
Thanks!

Can ARD 3 now share a screen across 2 different subnets

We have one central office. Clients access that office via a VPN. We can then share our screen with them as we work on a proof of a project.
It's a great solution, however, we can't with ARD 2.2 get it to work with two clients at once over the VPN.
An old Kbase article said that it wasn't possible to route screen sharing to two different subnets in the 2.2 version. But rather required all clients be on the same subnet.
Does anyone know or have the ability to test to see if this is different is 3.0. I'm hopeful that it is, as I can no longer find the old Kbase article saying that it wasn't possible.
Thanks,
Greg

Still no reply as to if this was resolved. I'm not so much worried about the move on the client side. As once we upgrade we have the luxury of upgrading everyone at once. I think that will be a smooth process.
However, our motivation to upgrade is dependant on wether or not the ability to route traffice over multiple subents is fixed or not. So we'll wait and see. If anyone can easily test this. I'd love to know. Sounds like a few other people are hoping to hear something as well.
Thanks in advance,
Greg

ACE load balancing servers on different subnets...

Hello,
I have the following issue.... need to load balance traffic between two servers already working in two different subnets (vlans), at this point is highly desirable to avoid changing IP addresses. Is it possible to accomplish this goal using ACE? routed or bridged mode? is it strictly necessary to have all servers belonging to a serverfarm in the same subnet?
Thanks in advanced for your support.

Hi,
You can do this, but you have to use client-NAT (Source-NAT) to force the return traffic to pass back through the ACE. You also then need static routes in the ACE context to point at each server. PBR is an alternative approach but I have not implemented that in a live network. The important thing is that the ACE sees both sides of the conversation.
The following extract from a configuration shows the basic principle:

Airtunes on different subnets - Why not?

I've been googling for the past week in order to try and find out if it is possible to use airtunes on different subnets before I actually buy the device only to find out that it does not satisfy my needs. For various reasons I can not have all my machines into the same subnet.
Searching revealed that because the Airtunes relies on Bonjour which in turn relies onto mDNS (i.e. mullticast) it simply can not be used in two different subnets. I've read that it cannot be done everywhere. I just can't understand the actual reason. Being a network engineer for more than 9 years I find it hard to accept that if both local subnets on my 3640 have multicast routing enabled it still won't do the trick. Can anyone shed some light into this? Unfortunately I still don't own the device so I can not do any tests...
Any help would be much appreciated.
TIA,

GrSpider -
Bonjour (and mDNS) work perfectly well across multiple subnets so long as your router is configured to support (i.e. route) multicast traffic. I use Bonjour on a constant basis across three subnets with both Mac and Windows platforms for a variety of service location purposes (printing, file sharing, streaming media) and have no problems whatsoever.
The AirTunes limitation you're referring to is an Apple policy decision, not a technical issue. It appears they've restricted iTunes<-->Airport streaming media connectivity to connections that originate and terminate on the same subnet. I assume they feel it's a mechanism to help enforce digital rights management.
Just to summarize: I routinely print to my Airport Express units across subnets, and share my iTunes music library to non-AirPort devices on different subnets; I just don't (can't) share my iTunes music library to an Airport Express on a different subnet.
That one limitation aside, they've been a great addition to my network.
FWIW.

Is it OK to have two SBS Servers with same name, on different subnets but connected over a VPN?

Hi Everyone,
I'm just about to connect up two SBS 2011 Servers with the same server name but on different subnets & domains over a VPN.
So for example both servers will have the name Server01, one would have an ip address of 192.168.85.5, the other 192.168.86.5, they both then would be connected over a VPN.
Can anyone foresee any issues with this configuration, like DNS & DHCP requests, adding new machines to the domain, mapping drives etc.
Many thanks,
Nick

Hi Larry & Strike First,
Thank you for your responses. I understand that this is an unusual situation. Basically I've recently taken over the IT support for this client. The client has just had a new phone system installed
& are asking if they can speak to each office internally, which can easily be done once I setup the VPN.
However I noticed whilst looking at this further that the Server names are the same, hence my question?
Am I right in saying that providing the workstations have a trust relationship with their own domain controllers through their individual domains on separate subnets, that hopefully there shouldn't be any DNS issues between the two domains and Servers?
I could build a new VM if you feel it would be better practice to do so?
Many thanks for your assistance,
Nick

ACS 5.0 having issues with different subnet AAA Clients

Dear All,
I am getting weird issue. My ACS 5.0 is in subnet 10.1.1.0/24. All the AAA clients which are in the same subnet can communicate with the ACS but different subnet cannot.
I have checked the firewall between them, Its allow any any with all services.
One more thing I have faced today is that now from only one switch (10.1.2.10) can access ACS but switches in the same subnet (10.1.2.0/24) cant access ACS as same previous issue.
Following are the logs of one switch(10.1.2.10) in different subnet can access ACS :

Ok, cool,
So this usually means that the switch is sourcing the requests from a difernet interface that is configured on the ACS.
I would guess that the ACS is reporting unknown NAS...
Can you please use the "ip tacacs source-interface" command to make sure the switch will source the Tacacs+ packets from the interface with the IP address for which you have the ACS configured to?
HTH,
Tiago

Is it possible to build two different L2TP/IPSec tunnels per subnet or per user?

Dear colleagues
I wondered whether anyone could help with this one.
Is it possible to build two different L2TP/IPSec tunnels per subnet or per user on a Cisco router or any other third party manufacturer? The idea behind is to allow different access to resources to different support technicians. Your help is much appreciated.

Sure, the ASA can use LDAP/AD information to select what access list should be applied for that specific user or group of users logging into the VPN. You can use whats called DAP or just LDAP Attribute Maps.

Two different Routers and same subnet, is it possible?

Hi i have been presented with a problem that a friend of mine is having.
There is two different Cisco routers on different location.
example:
router1 : 10.8.10.1 (has DHCP/FTP server)
router2 : 10.8.12.1 (needs to talk to DHCP/FTP server on router1)
the router2 has different ip configured but is it possible to change this to the same subnet as router 1? like 10.8.10.4?
The DHCP/FTP server have been defined with scope 10.8.12.0 and on the Cisco switch on router2 its been configured (ip helper address DHCP-IP)
this works, the clients connected to router2 gets ip from DHCP server ,but there is no FTP traffic.
i figure its because the DHCP/FTP server doesent understand the other IP, so if its possible to setup a kind of mulitVPN to get the same subnet on router2 as router1 the FTP server can "see" the other router2 because it has the same subnet and ip range.
Thank you for any experience, i really stuck on this one

John,
to simply put it having two routers on the same subnet is not possible as the purpose of a router is to route traffic between DIFFERENT networks. In order to accomplish this you will need routers and switches that understand VLANs and VLAN tagging.
Hope this Helps
