• Two guests with a different subnet on the same bridge vmnet0

  Hi all, I have a server in a data center.  The data center has awarded me two different

  Beaches of IP addresses with two separate subnets.  The first beach with the subnet to 255.255.255.248

  compatible with my 3 people systems hosts that use bridged networking on vmnet0.

  4th OS uses 255.255.255.0 and bridge over vmnet0, however

  I can not get on the net, can't even ping the gateway.

  Then the bridge vmnet0 manage two different subnets?

  Thank you

  Matt

  Yes, network bridge can have several subnets.  Bridged using, your virtual machine works like any other physical machine on the network.  So just as if two physical machines on the same physical LAN had different submet, they would not be able to communicate directly with each other, so also with your virtual machine having a different subnet.  With two subnets, you should probably two gateways.  If you cannot change the 4th VM subnet to match others, you would need a router between the two subnets.  (Again, same as if they were physical machines.)

• DMVPN hub & spokes multiple w / same subnet

  I have several (about 70) sites, but each site has the exact same LAN (192.168.2.0/24) each site has an ISR800.

  To my home office, I have a configured (ISR4331) DMVPN hub.  To my home office, I have a network that each of the customers on my shelves need to access (192.168.10.0/24).

  Any other access to the customers talk should go directly to the internet through this connection wan routers.  Rays will never talk to each other.

  My tunnels are all in the 172.16.0.0/23, with \172.16.0.1 being the hub network.

  What is the best way to do it?  I feel like some sort of NAT would be the solution, but do not know what direction to look in.  I found that other positions on duplicate networks, but only for duplication of unique network... not 70 x.

  I think I'd be considered for use instead of DMVPN EasyVPN server.  He can do NAT for you automatically.

  http://www.Cisco.com/c/en/us/products/collateral/security/iOS-easy-VPN/eprod_qas0900aecd805358e0.html

  Otherwise if you use DMVPN, then Yes, you will need to NAT each LAN to address IP Tunnel.  Just treat the external interface of Tunnel like any other IP address.  You will need to use a road map to match the traffic destined for the Internet interface and another for traffic going to the Tunnel interface.

  Something like:

  ip nat inside source route-map NAT-TUNNEL interface Tunnel0 overloadip nat inside source route-map NAT-INTERNET interface Dialer0 overload
  
  access-list 105 permit ip 192.168.2.0 0.0.0.255 any
  
  route-map NAT-TUNNEL permit 10 match ip address 105 match interface Tunnel0!route-map NAT-INTERNET permit 10 match ip address 105 match interface Dialer0

• Problem with RV0042 - mask subnet/router/gateway?

  Hi guys.

  I have a DSL here in Holland. To use my RV042 VPN function, I need the router to get the IP of the DSL modem. No problem, I bought a modem that can define transparant and with dhcp-parody the modem Gets the public ip address (say 85.223.12.34).

  The thing is, I can't access the internet, or in fact any IP that isn't in the first segment of the external IP address. So I can reach 85.123.34.56, but not 86.123.34.56. So I plugged the modem to a computer, set the transparent modem and the computer got the public IP address. And you know, I have a perfect connection, and everything works. Looking at my ip information, download the provider 255.0.0.0 subnet. Im not a Networking Wizard, but it seems to me that the problem lies here. But why is my stand-alone pc able to connect quite normal, but when I connect my linksys RV042 and internal diagnostic test (ping) of the router or a computer behind the router, obtaining an ip address, I don't get anything.

  When I ping manually, I also get the message "network is not available. Ping to an IP on the same subnet (for example, 85.111.111.111) goes perfect.

  I'm obviously missing something here. My colleuge said it could be and router/gateway (currently bridge) or a NAT problem-associated device.

  Please point me in the right direction.

  Intellectual property of addidional information:

  External ip address: 85.223.12.34

  External subnet mask: 255.0.0.0

  External gateway: 217.149.196.82

  External DNS: 217.149.196.6

  Internal IP address: 172.16.0.254

  Internal subnet: 255.255.0.0

  New firmware etc.

  Thank you guys!

  What static routes you add exactly on your RV? It's funny, it works now.

  WIndows seems to accept a gateway address that is not on a connected interface.

  The first line is the rule of default gateway:
  0.0.0.0 0.0.0.0 217.149.196.82 85.223.66.38

  The second line just tells you that 85.0.0.0/255.0.0.0 is connected to the ethernet adapter that has the IP 85.223.66.38.
  85.0.0.0 255.0.0.0 85.223.66.38 85.223.66.38

  Technically, the first route should now work. There is still no route for 217.149.196.82 in the routing tables. The only route that matches the destination IP 217.149.196.82 is the first route.

  But I guess that, in your case, that default gateway with 217.149.196.82 is actually connected to the network on the side of the VP, i.e. your ISP WAN runs two IP subnets on the same network. Since this first route runs on Windows, I guess that WIndows simply tries to find the MAC address of the 217.149.196.82 on the WAN using ARP interface (i.e., it assumes that the device with 217.149.196.82 is directly connected to the WAN Ethernet) and if something is used as default gateway. Is not really consistent with the ideal IP routing, but still works...

• DMVPN NAT - T emergency assistance?

  can someone please provide me with the DMVPN hub server configuration when the hub server is configured with nat?

  I will be grateful...

  Hi Mohammed,.

  I think you can visit these links:

  NAT-transparency aware DMVPN

  «Also added in versions IOS Cisco 12.3(9a) and 12.3 (11) T is the ability to make router DMVPN hub behind static NAT.» It was a change in the support of ISAKMP NAT - T. For this feature to use DMVPN spoke all routers and routers hub must be upgraded and IPsec must use the mode of transport.

  For the NAT-transparency aware improvements to work, you must use IPsec transport mode on the game of transformation. In addition, even if NAT-transparency (IKE and IPsec) can take in charge two peers (IKE and IPsec) translated the same IP address (using UDP ports to differentiate them), this feature is not supported for DMVPN. All rays DMVPN must have a unique IP address, after being translated NAT. They may have the same IP address before they translated NAT. »

  It will be useful.

• NAT Setup with a bridged interface possible?

  Hello, I have someone ask me if it is possible to configure a Cisco with NAT router for the wireless interface, but no NAT configuration on the fastethernet interfaces.

  So when I connect to the radio I get 192.168.1.10 for example 255.255.255.0.

  And when I connect to a fastethernet port I will get something like 92.16.235.141 255.255.255.248

  Is this possible? Or do I need a sepperate Access Point for that?

  I never said that it's a Linksys router. I was talking to a router Cisco (800 series)

  But thanks for your help, I've tried it in a test enviremont and it works.

  If I set up with a public IP address Vlan1 and Vlan2 with a privat IP this works, but only with one of the latest Cisco IOS images, because a second VLAN cannot do otherwise. I can then add vlan access fastethernet ports.

• ASA EzVPN with several remote subnets

  Hello world

  I'll have the challenge of EasyVPN installation based on ASA 5520, and ASA 5505 (with the ASA5505 as the vpnclient) with several networks behind the ASA 5505.

  Access by the network directly connected on the 5505 to the central site works very well.

  But the second network segment (which is behind a router on the directly connected network) cannot connect to the central site.

  I guess I need to specify that some sort of acl's to be able to do that.

  BTW we do not use tunneling split, because all traffic moves through the tunnel (no local internet access).

  The layout looks like this

  (--LAN--)-5520---5505-(--LAN1--)-ROUTER-(--LAN2--)-(WAN)-

  LAN1 and LAN connection works great through the EZVPN Tunnel.

  LAN2 connection to the LAN does not work through the Tunnel of EZVPN.

  Here is the configuration used so far (outside the normal SHEEP, groups of objects and stuff ISAKMP crypto):

  Client:

  vpnclient Server 10.x.x.x

  extension-mode network mode vpnclient

  EzVPN vpngroup vpnclient password *.

  I hope you can help

  Unfortunately, it is not supported on the platform of the SAA. With EasyVPN on the SAA, only the connected networks can be advertised. To accomplish what you want to do, you need to configure a static IPSec tunnel and announce local networks via ACL interesting traffic. You can also use an IOS device that does not have the capabilities of "multiple subnet" with EasyVPN.

• NAT overlapping with remote VPN access

  Hi all

  My client has an ASA 5510 at the main location. We're shooting for their remote access VPN SSL needs. 30 or so remote users.

  The problem is that the main site has a number of network 192.168.1.0/24. The number of Linksys routers bought on shelf at any store of default.

  Obviously, by default, it does not work. When users connect to the VPN from home, it connects but network resources are not available.

  I read about overlapping NAT with tunnels of site to another, but that all remote access? Is it possible as well?

  Any help to point me in the right direction would be much appreciated.

  Thank you!

• IPSEC VPN from Site to Site - NAT problem with address management

  Hi all

  I have two Cisco ASA 5505 performing of IPSEC Site to Site VPN. All traffic inside each firewall through the VPN tunnel and I have full connectivity. From site A, I can connect to the inside address of the ASA at the site B and launch of the ASDM or SSH, etc.

  The problem I have is when I'm logged on the ASA site B management traffic is given the external address. I created this as interesting traffic to get it to go through the VPN but I need to use the inside address of ASA B. The following is possible:

  • If I can make the ASA Site B to use inside interface as its address management (I already have management access to the inside Interface)
  • I have NAT can address external interfaces to Site B before moving through the VPN tunnel management traffic so that it appears to come from Site B inside the address
  • I can NAT VPN traffic as it appears in the Site A for management traffic to Site B on the right address.

  The problem is that my PRACTICE Please also come from this address and I need the application before being on an internal address to even if my CA.

  Thanks for any help.

  Ian

  Thanks, I understand what you are trying to achieve now.

  However, I think that I don't have good news for you. Unfortunately PEIE request can be initiated of the SAA within the interface, as there is no option to start the query from the inside interface. With other features of management such as AAA, logging, you have an option to specify what ASA desired originally to demand from interface, but CEP doesn't have this option.

  Here's how you can configure under the trustpoint crypto, but unfortunately by specifying the interface doesn't not part of option:

• NAT crashed with 12.1.0 Pro workstation

  Yesterday I've upgrade to Workstation Pro 12.1.0 on my Linux host. I mainly run Windows virtual machines and connect to these via Remote Desktop. Virtual machines go NAT LAN and that's why I set up NAT port forwarding to the ports of Windows Remote Desktop. This Setup worked great for a few years.

  With 12.1.0 (from 12.0.1) update it's broken. The Windows prompt has network access (for example it can access SMB shares in the network) and everything seems fine, all the necessary processes (e.g. vmware natd(8)) are running, ' / usr/bin/vmware-networks - status says it all works. So I try to connect to the virtual from Windows via Remote Desktop machine (I'm on a Mac and use Desktop jump as a customer). BOOM. The connection failed and crashed vmware-natd(8). VMware-networks now says that the NAT service is not running.

  Today, I went down to 12.0.1. and the exact same configuration works without any problem.

  So I guess that something has changed in the NAT region. I'm missing some configuration options, or is there a bug in the new vmware natd(8)?

  I'm sorry that Workstation 12.1.0 have this bug.

  We have an internal bug to track this issue.

  Currently you please come back to use Workstation 12.0.1 instead?

  Thank you!

• VLAN community private with several internal subnets.

  I'll set up a testbed for a new multi level application that we are lacking in our company.

  I intend using several PVLANs community, because we are cloning machines in each community PVLAN so their IP addresses and names are identical to the nearby town of PVLAN.

  Everything works fine until I try to route traffic to different IP addresses the community of PVLAN. I have 3 different networks in the PVLAN and I'm not sure what I need to do to ensure the that each system interface allows to correctly identify the next interface.

  For example, I have the following networks:

  10.10.1.x

  10.10.2.x

  10.10.3.x

  If I have storage on 10.10.3.x devices, they are not recognized by systems using 10.10.2.x AND 10.10.3.x.

  I do not use gateways because they seem totally unnecessary if we the community of PVLAN.

  I read a blog mentioned using vyatta for this, but I have no experience with it and their Web site has been overwhelming when I tried to understand what product would even meet my needs.

  It could be any type of router actually, but there must be something available that could handle Layer 3, i.e.: IP. It is impossible for two IP hosts on the other subnet IP to communicate without going through a router.

• Understand the NAT translation with route map

  Hello

  I try to configure the server EZVPN on SAA and EZVPN client on router 881. I found on the documentation to the NAT translation on the client side

  My confusion is that I should use the deny on the access list statement? If anyone can explain this, enjoy it.

  IP nat inside source overload map route EzVPN1 interface FastEthernet4

  access-list 103 deny ip 192.168.3.0 0.0.0.255 192.168.2.0 0.0.0.255
  access-list 103 allow ip 192.168.3.0 0.0.0.255 any

  allowed EzVPN1 1 route map
  corresponds to the IP 103

  Hello

  So that's the explanation for the statement "denied" on the ACL for NATing.

  Based on the config, 192.168.3.x here is the network behind your 881 and 192.168.2.x is the network behind the ASA. Let's suppose you're trying to install between 192.168.2.10 and 192.168.3.10. When this package is delivered to the 881, it checks first the characteristics of penetration on the incoming interface (such as the ACL, political, policy-services, etc.) and before checking the 'IPSEC security associations", it checks the NAT configuration.

  Now, your IPSec security association will specify for 192.168.2.x 192.168.3.x traffic to be encrypted and then sent. If we do not have the declaration of 'decline' in the ACL, the 881 will be NAT incoming packets and then the IP source in the package will get changed the IP address of the interface of SA4.

  This match is no longer the configuration of IPSEC SA and therefore not get encrypted. Therefore, we must have the statements 'decline' to ensure that VPN traffic is not coordinated and is therefore correctly.

  Hope this helps!
