On Pix VPN tunnel to the same subnet

• Two VPN tunnels on the same device with the same protected networks

  There is a remote site that wants me to put in place two separate tunnels of VPN with the same internal IP at each end. FOR EXAMPLE

  LAN = 10.212.170.201/32, 10.212.170.202/32

  Remote network 192.168.0.0/24 =

  I currently have a tunnel between the above:

  End Point distance = 111.93.152.186

  Local endpoint point = 198.205.115.252

  Now, they want to set up a VPN for the same networks between:

  End Point distance = 115.115.130.34

  Local endpoint point = 198.205.115.252

  It is my understanding that the Cisco ASA 5520 can do. The only way I've seen this done with Cisco hardware is to use two ASAs, but there may be a way to use the costs of road or some other tricks to make it happen.

  I'm open to suggestions.

  Is a backup?

  In, specify endpoint remote second as a "backup" of the peer in the first virtual private network.  Alone will be active at the time - but there are toggled if the VPN in first dies.

• GRE and IPSEC VPN tunnel over the same interface

  My client is currently connected to a service provider of call through a GRE Tunnel over IPSEC. They chose to move all connections to a VPN site-to-site traditional behind a firewall, here, to your corp office.  As the questions says, is possible for me to put in place the VPN site to site on the same router? Interface Tunnelx both ethernet have the same encryption card assigned to the destination router.  I thought that traffic could divide by identification of traffic 'interesting '.  Thanks for all the ideas, suggestions

  Thanks for the additional information. It takes so that the existing entries in ACL 101 remain so the existing tunnel will still work. And you have to add entries that will allow the new tunnel. Editing an ACL that is actively filtering traffic can get complicated. Here is a technique that I use sometimes.

  -create a new access list (perhaps ACL 102 assuming that 102 is not already in use).

  -Copy the entries of ACL 101 to 102 and add additional entries you need in places appropriate in the ACL.

  -Once the new version of the ACL is complete in the config, then go tho the interface and change the ip access-group to point to the new ACL.

  This provides a transition that does not affect traffic. And he made it back to the original easy - especially if something does not work as expected in the new ACL.

  If the encryption of the remote card has an entry for GRE and a separate entrance for the IPSec which is a good thing and should work. I guess card crypto for GRE entry specifies an access list that allows the GRE traffic and for IPSec crypto map entry points to a different access list that identifies the IP traffic is encrypted through the IPSec tunnel.

• Cisco ASA cannot create several tunnels at the same address in hand?

  We have several remote sites with Linksys WRVS4400N and Smoothwall firewall/vpn devices.  I need these sites to be able to connect to several tell-contiguous subnets to our main office.  This was done easily with smoothwall and linksys.  You create a separate tunnel for each subnet, and voila, you're done.  However, when I tried this with our ASA newly installed, it won't let me create several tunnels at the same address of the remote peer.  It is a problem because these sites have only a single IP address public static.  Did I miss something or ASA not allow connections to and from multiple subnets form a site with a unique address peer?

  Resembles the limitation on the WRVS4400N as Cisco ASA supports several subnets by tunnel.

  Is there anyway that you can configure a subnet more instead of specific subnets on the ACL?

  For example:

  If you 192.168.0.0/24 and 192.168.1.0/24, instead of having 2 subnets configured, you can combine them into 1 subnet 192.168.0.0/23

• IPSec VPN between ASAs with same subnet for disaster recovery

  Hello

  I need some clarification from you guys.

  To do disaster EasyVPN tunnels for the Cisco ASA 5505 firewall recovery site. Now, there is only one main site and 3 remote sites.

  Dr., must use the same subnet that it is on the main site because virtual machines Vmware will be replicated to DR.

  For the DR we use Double-Take software.

  What is the best solution for this? I think we could use NAT of Destination on ASAs. Other sites (HQ and remote control) will be directed to only address NAT of the

  DR and not real which is the same as on the main site.

  So guys, will this work? We are using IPSec VPN? In packet - trace on ASA, I see that the package is the first using a NAT, and then encrypted, so it should work, Yes?

  I hope someone can confirm this.

  I can confirm that this will work certainly,

  for prior type natting see 8.3:

  http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080b37d0b.shtml#diag

  for 8.3 and later it is also achievable.

• WiFi AR5007 802. 11 b / g adapter cannot talk about bridge WET11 Wireless on the same subnet

  Hello

  My HP Compaq Presario C700 VISTA laptop (a AR5007 802. 11 b / g WiFi adapter) and the printer are on the same subnet. The laptop is WiFi connected to my WRT54G2 router/switch and the printer is connected to the workgroup switch that connects to the router via the LinkSys WET11 Wireless Bridge.

  The installer works fine for over a year until he was there when my VISTA does not see any PC on the Working Group 3 weeks pass including the printer. However, the WAN access is not affected.

  I did the filming of following problems (in order):

  1. check the network settings on the laptop VISTA (x.x.x.29) and (x.x.x.201) printer and all look kosher.    (All my PC including notebook computer and printer have IP STATIC)

  2. check the router and the parameters of bridge and fines all eyes (router - XXX1, bridge - x.x.x.140).

  3 Ping printer, bridge, and other PC and received messages "Destination Unreachable Host" or "Request timed out". Although all are on the same subnet. Pingée router is OK.

  4 remove and re-add the wireless profile and tried to connect again. Same problem, no joy!

  5 started VISTA in safe MODE with NETWORK. Once again, the problem has persisted but at least eliminated applications as a potential source of problems.

  6. recycled power switch/router/workgroup bridge. No joy!

  7 WiFi connected other laptops to the same router (WRT54G2) and can ping other PC and printer END.    This means that the problem is limited to my VISTA laptop.

  8 given that the problem is on my VISTA and applications are not the source (see #5) of the problem, then probably the AR5007 802.11b.g wireless network card driver is original so I downloaded driver at HP and installed with version 7.3.201.25.  Problem is persistent...  Arhhh!

  Could there be something else that I missed? Can someone please help.

  Thank you

  You are the very welcome, John.

  Yes this driver will work fine on Vista Home Premium.

  According to the notes on the driver, it can just be run without uninstalling the current pilot you have on there now.

  After executing, you can confirm it 'takes' by going into Device Manager, expand network adapters, click the atheros wireless card, click the driver tab and you should see the installed version 2011.

• How to determine if 2 IPs are on the same subnet

  Hi all!

  I have a Client/Server connection over a network, and I wants to determine if they are part of the same subnet.

• Case 'not the same subnet mask' - WRT54GL

  Hello

  I recently bought a WRT54GL router and tried to feed it with data from my ISP.

  I entered these data to my Windows system as well as my older router and it worked fine.

  These are:

  IP: 213.211.57.xx

  Subnet mask: 255.255.255.0

  Gateway: 213.211.56.1

  However, I get the error "not the same subnet mask" described here .

  If I run "ipconfig/all" to the machine which can be used to connect to the net, I don't get any additional useful info that I described here, (he is also in Czech :-)

  And there is no obvious conclusion in this forum thread.

  Any suggestions?

  Kind regards

  OK, so I've solved this by changing the bridge and it works now.

• public static IP on the same subnet of both internet and local

  I need to configure my little guy with ip static on the same subnet on the side of the router/internet and the side room, but it does not.

  I will allow me to dhcp on the side of the router/internet and then statically assign an ip address from the same subnet on the local side, but then it does not pass on my dhcp server dhcp queries.

  suggestions?

  Yes. Configure the WRT with a LAN inside your main LAN IP address. Disable the DHCP server on the WRT. Wire then a main WRT to your local area network LAN port. Do not use the internet port on the WRT.

• Several groups of PS in the same subnet

  Is there something wrong with having two PS series groups (and, therefore, their members) in the same 24 subnet and the same VLAN?  We have a PS Group in the same place we are moving to another site that already has a PS Group.  We would like to just take advantage of the networking and configuration of VLAN, that we have so I just want to check that it is not a problem to do this.

  Thank you

  Bryan

  Hello Bryan,

  The only limits are the IP addresses available, switch ports available and that the switch can handle the load increases.  Especially if you share the SAN and LAN traffic to the same switch.  Also the link between the switches might need to increase as well.

  There is nothing inherit in the design to prevent it.   In my lab, I have quite a bit on the same subnet.

  Kind regards

• Eql different groups on the same subnet

  Hello

  Quick question...

  We have a PS6000 four in a group of storage in an iscsi network 192.168.0.0/24. We have now bought two PS6100XV and think about maybe create another group of storage for the new boxes eql. The reason is in the future, upgrade to 10 GB on the new group.

  The question is if we create a new group to the PS6100VX, is it necessary to have a new iscsi LAN with a different IP subnet or can we use the same subnet 192.168.0.0/24 as PS 6000 are on?

  You can stay on the same subnet.   Your switch is the limiting factor.

• Directly connected to the same subnet - still get 2 hops?

  I changed the ip numbers in this example of those public to the private sector

  | IP switch of the provider: 192.168.0.162/29. ------ | Reference Dell 6248 ip: 192.168.0.164/29 | ------ | Halon SX 200 ip: 192.168.0.166/29 |

  A Halon router for ip tracetroute: 192.168.0.163 says:

  1 192.168.0.164

  2 192.168.0.163

  Should not go directly to 192.168.0.163 with 1 jump? Am I missing something here?

  I've implemented a quagga and two HP Procurve 2626 router and could not reproduce the problem.

  Does anyone know if I'm missing something? In theory I should be able to simply get 1 jump to one IP address on the same subnet - right? Feels like the Dell switch made unnecessary routing...

• What are the vSphere components must be on the same subnet?

  VSphere components, those who need to be on the same subnet / vLAN?

  For example:

  vCenter Server and ESXi hosts?

  Groups separated from ESXi hosts are on separate VLANS / subnets? What is the limit of the number of hosts ESXi I should have on one vLAN to avoid having too much broadcast traffic?

  vCenter Server and he associated with SQL Server?

  VMware Update Manager and vCenter Server?

  VMware Update Manager and ESXi hosts it updated?

  There is no technical requirement that vSphere components must be on the same IP subnet. You can have all the components on a separate and routed (or even a firewall, you implement granted sufficient rules) subnet without problems. If that made sense, however, is a completely different question.

  vCenter Server and ESXi hosts?

  Does not really matter, but makes the most sense to be on the same subnet.

  Groups separated from ESXi hosts are on separate VLANS / subnets? What is the limit of the number of hosts ESXi I should have on one vLAN to avoid having too much broadcast traffic?

  If they are managed by the same vCenter, or similar commercial purposes, I would put them on the same subnet. I only consider something a subnet extra for things like DMZ-Clusters, that can be distinguished from any other as much as possible. A vMotion VLAN cluster might be a correct point in a normal scenario too.

  ESXi hosts really do not generate any significant broadcast traffic, apart from a few ARP requests here and there. This isn't Windows, after all, and even if that were the case, the time when you had to worry about the reasons broadcasting with 'only' a few hundreds or thousands of systems on a broadcast domain have long been more with the advent of fast and gigabit ethernet.

  vCenter Server and he associated with SQL Server?

  VMware Update Manager and vCenter Server?

  Even once it does not really matter, but I would put them on the same subnet unless I have a very good reason not to.

  VMware Update Manager and ESXi hosts it updated?

  As long as they are not connected via a WAN snail, causing the staging of updates hours, that's fine.
