3 RV320 VPN with a local IP address

Hello..

I have 3 RV320 routers, I try to connect by VPN all routers together, the problem is I have a server on a single router 192.168.1.200 and I need to connect the terminals to the other routers on the internet...

any suggestion?

Connect VPN tunnels between all 3 units.  Please keep in mind that subnets are different.  Get close to the tunnel.  Ping 192.168.1.200 at two remote sites to verify connectivity.  Try the terminals.

  • ASA vpn with a public ip address different addresses

    Hello world. I can not find someone who can give me an answer 'for sure' of this thing. I want to connect via vpn ASA5505, called 2A and b. inside one we have net 10.0.0.0/24 and 10.0.1.0/24 net b. now, we can have 2 outside for one ip addresses (e.g. 215.18.18.10 and 222.26.12.12) because we have 2 providers to connect to the internet. the asa can follow 2 VPN - with the same cryptomap for the destination inside) so that if a grave he will switch to the other vpn by itself?

    This thing can be done with other cisco devices (for example, a 2800 series router?)

    Thank you very much

    Who are you looking to

    1. If the failure of the connection to B then A will use secondary WAN connection to try to raise the tunnel.

    I would use the backup ISP for this function.

    2. If the connection to A failed then B will try to set up the tunnel with secondary address peer.

    You can set several counterparts by using cryptographic cards to provide redundancy

  • If a PC with a DHCP server is connected via VPN, with her serve IP addresses on the tunnel?

    Situation: we have a few portable computers test Ubuntu running DHCP servers.  We need get the updates and other changes in corporate network sometimes.  Today, we turn off the DHCP server, set up to get an IP via DHCP (besides) and make our updates.

    Problem: we do not want someone accidentally connect the laptop to the corporate network, while its DHCP server is running.

    Question: so, if we go via wifi using a Cisco VPN client, the DHCP server IP addresses above the tunnel?

    Thanks for reading.

    N ° DHCP uses layer 2 broadcasts to disseminate IP addresses.  Because your clients are connected via VPN, there is no contiguity of layer 2.  The only way he would accidentally do it is if you have configured an address to support IP dhcp as one of your VPN clients on the network, which I imagine you wouldn't.

  • ASA 5510 VPN - using a public IP address for the local network

    Hello, I have a problem which is probably very simple, but I can't seem to understand.

    I set up a site IPsec connection to another with a company, something I've done many times before without a problem. I use ASDM to configure this, because it is quick and painless, usually.

    We have one number of other site-to-site currently configured connections and works very well on this ASA, these are configured with the "Protected network - LAN" configured with the IP private of hosts within our network, we want to make available through the separate tunnels. This includes the configuration setting on our ASA for each connection to "guests aside ASA exempt from NAT.

    With this new link, however, the company asked us to use a public IP address for the host that we want to achieve through the tunnel. I don't know why, but they demand it. So I added a NAT rule for inside the host and set up the connection with the public IP address under "Local network". During the test to try to reach a host to their side, the tunnel didn't even try to open.

    What is the method here? I don't see where I'm wrong. I'm guessing that the 'host side ASA exempt from NAT' does not require for this, how if the ASA would know which internal host is the public IP address.

    Any ideas?

    Hi Leo,

    The steps are:

    1. Add the policy rule NAT for the specific host.

    2 - define the IP NAT as your LOCAL NETWORK address in the encryption settings.

    3 make sure that there is no rule NAT exempt for this host to the specific destination.

    What happens if you run a package tracer?

    Thank you.

  • How can I specify a default gateway for users of AnyConnect with a local pool of IP?

    Hi all

    This question relates to my ASA5510 8.0 software (4) running.

    For many of my AnyConnect group strategies, I use a local pool of IP to assign addresses to remote clients.  The pool is 10.1.50.1 - 10.1.50.250.  The problem is that when clients connect, they get a default gateway 10.1.0.1 it would be OK in a properly configured network, but it's not really one of those.

    I don't think there is any place where I can specify the default gateway value, is there?  What is the right way to work around this problem?

    Thanks in advance,

    -Steve

    Hello

    Find out what...

    Cisco AnyConnect VPN Client connection Ethernet card:

    The connection-specific DNS suffix. : vcnynt.com

    ... Description: Miniport Adapter virtual cisco AnyConnect VPN for Windows

    Physical address.... : 00-05-9A-3C-7A-00

    ... Default gateway. : 10.1.0.1.

    10.1.50.1 is a part of 10.1.0.0 subnet. By design, to make the client VPN routing compatible with machines Vista. We had changed the functions of IPs for the DG on the client. It had been noticed that if you have the same DG ip address as the ip address of the virtual card it will not work. So what you see is good behavior.

    In other words, Anyconnect will show the first ip address in the subnet as the DG which in your case is 10.1.0.1.

  • IPSEC VPN with Dynamics to dynamic IP

    Hello

    I tried IPSEC VPN with dynamic IP to dynamic (router to router) for some time. But still can not auto-établir the tunnel.

    Is someone can you please tell me if it is possible to do?

    If so, please share with me the secret to do work.

    Thank you!

    Best regards

    Rather than the Crypto map, I would use the profile of Crypto.  Then, establish you an IPSEC tunnel.  The beauty of the profile, is that you can run through it routing protocols, and you do not have to change constantly the cards whenever you change the topology of the network.  The "* * *" in the timer event is "minute hour day week month" so "* * *" is updated every minute.  In Tunnel destination, it's an IP address, not a hostname that is stored, but when you set it, you can put in a HOST name and it converts to the moment where you configure it to an IP address.

    So, if you type:

    config t

    interface tunnel100
    destination remote.dyndns.com tunnel

    output

    See the race int tunnel100

    It shows:

    interface Tunnel100
    tunnel destination 75.67.43.79

    That's why the event handler goes and becomes the destination of tunnel every minute what ever the DDNS says that is the new IP address.

    I have seen that two of your routers running DDNS.  They will have to do this.

    AAA-server RADIUS NPS (inside) host 10.10.18.12

    key *.

    authentication port 1812

  • IPsec VPN remote has an IP address and does not

    I'll put up a simple remote IPsec VPN with a 8.4 ASA. What I want to do is the remote user can VPN into the ASA, from there, it can
    Through the external Web pages in the internet. and we would not use split tunneling.

    outside infterface is 192.168.1.155/24, which is inside our network and this subnet works very well to the outside.
    the pool for vpn is done 192.168.0.0./24(please attention to the 3r byte)

    I configured and the remote user can vpn in and get an IP address from the pool. but it seems that he can't do anything. It cannot ping anything.
    I suspected that I use the NATTing.

    Can you tell me what is configured in the wrong? I guess I'll be confusion as this traffic must be natted and which do not need.

    Thank you

    Well, your inside interface of the ASA's 'stop', this is why you can't connect.

    Thus, you must also configure: management-access to the Interior, to be able to do a ping of the inside interface of the ASA and the interface must be up before you can ping.

  • VPN problem when local lan IP is IP LAN Corp.

    Hello

    I'm having a problem to access corporate services when an example of one of our servers IP address matches an IP address of a local host from the local network, accessed from.

    Is there a way to bypass and or solve this problem?

    I use split tunnel, I send you all DNS requests through the tunnel and assigning the DNS name.

    I inherited this network which is a 192.168.0.0/23 with many services on 192.168.1.x that match easily private local lans.

    Hello Michael,

    To resolve the overlap, you need hide the remote with a NAT rule network, so that VPN clients point to an address using a NAT on the SAA.

    Can I know the version of your ASA?

    Thank you.

    Portu.

  • 2911 w/security - VPN with DHCP Relay to Win2K8, routing fail

    Hello

    I have a 2911 router and tries to terminate a VPN inside.

    I want to do this is before the DHCP request to a Server 2008 inside.

    I actually received this part to work.  But it seems to be, 2911 router is not set the VPN clients on a VLAN internal associated with the range of network, the DHCP server is to give.  Or all least, does not have a flow of information between the IP address of the VPN Client and the router itself.

    (washed config below)

    Example: VPN Client obtains the IP address of 10.101.55.10.  The router has a loop (or subinterface in my last iteration of the config) address of 10.101.55.1.

    And yet, when my VPN client connects, I am not able to ping to an IP that my router has.  I can ping myself (10.101.55.10), but I only ping the router in any way which.

    Does anyone have any ideas?

    Yes, it looks like you might have as a subnet of more large covered in your routing protocols internal hence set up 'reverse-road '.

    Good to hear it works now. Kindly, please mark this post as responded while others can learn from this post. Thank you.

  • Remote host IP SLA ping by tunnel VPN with NAT

    Hi all

    I did some research here, but don't drop on similar issues. I'm sure that what I want is not possible, but I want to make sure.

    I want to monitor a remote host on the other side a VPN. The local endpoint is my ASA.

    The local INSIDE_LAN traffic is NATted to 10.19.124.1 before entering the VPN tunnel.

    Interesting VPN traffic used ACL card crypto:

    access-list 1 permit line ACL_TUNNELED_TO_REMOTE extended ip host 10.19.124.1 192.168.1.0 255.255.255.0

    NAT rules:

    Global (OUTSIDE) 2 10.19.124.1 mask 255.255.255.255 subnet

    NAT (INSIDE_LAN) 2-list of access ACL_NAT_TO_REMOTE

    NAT ACL

    access-list 1 permit line ACL_NAT_TO_REMOTE extended ip 172.19.126.32 255.255.255.224 192.168.1.0 255.255.255.0

    This configuration works very well for traffic from hosts in 172.19.126.32 255.255.255.224 is 192.168.1.0 255.255.255.0.

    However, I like to use "ip sla" on the SAA itself to monitor a remote host with icmp ping 192.168.1.0. This would imply NATting one IP on the ASA to 10.19.124.1, but I do not see how to do this. None of the interfaces on the SAA are logical, to use as a source for this interface.

    Thanks for ideas and comments.

    Concerning

    You are absolutely right, that unfortunately you won't able to NAT interface ASA IP address. NAT works for traffic passing by the ASA, don't not came from the SAA itself.

  • VPN with NAT Interface

    Hello

    I am trying to set up a VPN between a VLAN I have defined and another office. I have been using nat on the interface for internet access with a NAT pool.

    I created the VPN with crypto card and the VPN is successfully registered.

    The problem I encounter is that with NAT is enabled, internet access is working but I can ping through the VPN.

    If I disable NAT, VPN works perfectly, but then him VLAN cannot access the internet.

    What should I do differently?

  • Am200 refuses a valid local (public) ip address (local ip address is not a valid address)

    Hi there, having some problems with my current ADSL line and planned on the secondary use of the am200 as a dsl modem to check if she behaves better under the adsl2 +.  But when I go to enter the desired local IP (94.30.x.x), subnet mask (255.255.255.248) turn off the dhcp server and click ok, I gives me the error 'local IP address is not a valid address' and unable to continue.  He of course will allow me to use private IP addresses, but this modem will not connect to my firewall/web server (i.e. 94.30.x.x + 1) I like the modem to be an imaginary ip address, but a real, routed.

    Before making a request for official support of linksys (now cisco), I thought I would check to see if someone has a possible solution.  I've just updated firmware for 1.19.02 and it still gives the same error.

    Thank you.

    Please delete this thread, using another firmware, I was able to select a real IP address.  I hope that linksys (cisco) will be realease an official firmware to solve this problem, but in the meantime, thanks for the work Geremia!

  • I can connect to my network, but with access "local only".

    Access to the "Local" network only
    I can connect to my network, but with access "local only".  Internet became more intermittent (not sure if that is related or if I guess it) and did not work in several weeks.  Desktop computer is plugged into the router, but have the same problem when it is plugged into the DSL modem.  Other computers on the same router (wireless or other) work very well.  Recently, I removed Mcaffee and installed MS security essentials.  I uninstalled mcaffee of programs and settings then used the mcaffee removal tool to lighten the rest.  I uninstalled and reinstalled MS security essentials.  I thought it might be a firewall issue, but I get error 0x6D9 when I try to start it.  I tried all the steps in the following post, nothing helps.  Any other suggestions?

    ______________________

    You can follow the steps below and check if that helps you solve the problem.

    Method 1

    Try to power cycle the router and the computer and check if it helps.

    On the PC:

    1. Save your work and restart the machine.

    On the router or modem (if wireless printing):

    1. Unplug the router and the modem.
    2. Wait 30 seconds.
    3. Plug in the modem and wait for it to come to the ready state.
    4. Plug in the router.

    After you put cycle check the connection between the router and the computer.

    Method 2

    If the steps above do not help, you mayreset TCP/IP stack. To reset access the link below and either click on "Fix it for me" or follow the instructions to fix it yourself:http://support.microsoft.com/kb/299357
     
    Disable the IP helpdesk:
    1 hold the Windows key and type R, type "services.msc" (without the quotes) and press enter
    2. scroll down to the IP assistance service, right-click on it and select Properties
    3. in the drop-down list box that says "Automatic" or "Manual", set it to disabled and then click 'apply '.
    4. then click on "Stop" to stop the service from running in the current session
    5. click on OK to exit the dialog box

    Method 3

    Disable IPv6 and remove IPv6 virtual cards:
     
    Try to uninstall IPv6 on all interfaces, the removal of virtual cards of IPv6 and reset the TCP/IP stack. To remove the IPv6, go to the properties for each network adapter, and deselect the check box next to the Protocol "Internet Protocol version 6 (TCP/IPv6), which will turn off, or select it and click on uninstall, which withdraw power off the computer.» Then go into Device Manager and remove any 4to6 adapters, adapters miniport WUN or tunnel adapters.
    NOTE: You should do this for each network connection, even if they are disabled.

    Method 4

    Disable the DHCP Broadcast Flag:
    Link: http://support.microsoft.com/default.aspx/kb/928233
    Important: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click on the number below to view the article in the Microsoft Knowledge Base:
    http://support.microsoft.com/kb/322756.  How to back up and restore the registry in Windows
     
    Windows Vista cannot obtain an IP address from certain routers or some non-Microsoft DHCP servers
     
    To resolve this issue, disable the DHCP BROADCAST flag in Windows Vista. To do this, follow these steps:


    1. Click Start, type regedit in the search box, and then click regedit in the list programs.
    2. If you are prompted for an administrator password or for confirmation, type your password, or click on continue.
    3. Locate and then click the following registry subkey:
    4 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\ {GUID}
    5. in this registry path, click the (GUID) subkey that corresponds to the network adapter that is connected to the network.
    6. on the Edit menu, point to new, and then click DWORD (32-bit) value.
    7. in the new area #1, type DhcpConnEnableBcastFlagToggle and press ENTER.
    8. right click on DhcpConnEnableBcastFlagToggle, then click on modify.
    9. in the value data box, type 1 and then click OK.
    10. close the registry editor.
     
    By setting this registry key to 1, Windows Vista's trying to get an IP address using the BROADCAST flag in DHCP Discover packets. If that fails, he will try to obtain an IP address without using the BROADCAST flag in DHCP Discover packets.
    You can also try uninstalling and reinstalling the driver for the wireless card.

  • How to bind a VPN (TX via VPN) with a sat (RX via DVB - S2) / Windows Vista Home Edition / Multiple dial conections

    I use a Windows Vista Home Edition on a laptop. The system connects to the Internet through a cellular router EDGE (via Ethernet) and receives the data by linking receiver DVB - S2 satellite broadband connected via a USB interface. The connection is through a VPN. Windows Vista loses the symbol of the "blue planet", as soon as the VPN connects. Authentication and connectivity is OK. DNS also works OK by the way VPN, with pointing to the VPN IP address 0.0.0.0.  The diagnosis indicates an error where Vista says that she finds multiple active dial connections. Y at - it a configuration option that allows me to bind the interface transmission (VPN) with return channel satellite?  The same software and configuration under Windows XP SP3 works OK.

    Thanks in advance for your advice.
