Renew the certificate - Cisco VPN (the router)

Hello!

I have to renew my certificate and I need to do this, generate a new CSR.

My doubt is if I generate a new CSR my current certificate will be lost or not.

The command I use to generate a new CSR is:

# crypto ca enroll XXX

Thank you.

Hi Anderson,

If you create the CSR in a different trustpoint, you will not lose the current certificate.

It may be useful

  • Renewal of certificates Cisco ISE Admin and EAP

    Hi on board,

    Maybe I'm asking a rather stupid question here, but anyway :)

    Currently, I think about how renew a certificate admin/EAP on a node of the ISE and the effect on the endpoint authentication.

    Here's the thing that I do when I install initially an ISE node

    1.) creation of CSR on ISE (PAN) - CN = $FQDN$ and SAN = 'name of FQDN as well. "

    2.) sign CSR and certificate of bind on the ISE node - done

    Now, after 10 months or two (if the certificate is valid for one year) I want to renew the certificate of admin/EAP ISE.

    Creation of CSR: I can't use the $FQDN$ like CN, because there is still the current certificate (CN must be unique in the store, right?)

    So what to do now? I really need to create a temporary SSC and make the admin/EAP certificate, remove the current certificate, and then create a new CSR? There must be a way better and more important to do nondisruptive.

    How you guys do this in your deployments?

    Thanks again in advance, and sorry if this is a silly question.

    Johannes

    You can install a new certificate on the ISE until he's active, Cisco recommends to install the new certificate before the expiry of the old certificate. This period of overlap between the former certificate expiration date and the new certificate start date gives you time to renew certificates and to plan their installation with little or no downtime. Once the new certificate enters its valid date range, select the EAP or HTTPS protocol. Remember, if you turn on HTTPS, there will be a restart of the service

  • IPSec site to site VPN cisco VPN client routing problem and

    Hello

    I'm really stuck with the configuration of ipsec site to site vpn (hub to spoke, multiple rays) with cisco vpn remote client access to this vpn.

    The problem is with remote access - cisco vpn client access - I can communicate with hub lan - but I need also communication of all lans speaks of the cisco vpn client.

    There are on the shelves, there is no material used cisco - routers DLINK.

    Someone told me that it is possible to use NAT to translate remote access IP-lan-HUB customers and thus allow communication - but I'm unable to set up and operate.

    Can someone help me please?

    Thank you

    How the DLINK has been configured for traffic between the site to site VPN subnets? You are able to add multiple remote subnets on DLINK? If you can, then you must add the pool of Client VPN subnet.

    Alternatively, if you cannot add multiple subnet on DLINK router, you can change the pool of Client VPN 192.168.6.0/24, and on the crypto ACL between the site to site VPN, you must edit the 180 existing ACL

    DE:

    access-list 180 allow ip 192.168.7.0 0.0.0.255 192.168.1.0 0.0.0.255

    access-list 180 allow ip 192.168.200.0 0.0.0.255 192.168.1.0 0.0.0.255

    TO:

    access-list 180 allow ip 192.168.6.0 0.0.1.255 192.168.1.0 0.0.0.255

    Also change the ACL 190 split tunnel:

    DE:

    access-list 190 allow ip 192.168.7.0 0.0.0.255 192.168.200.0 0.0.0.255

    access-list 190 allow ip 192.168.1.0 0.0.0.255 192.168.200.0 0.0.0.255

    TO:

    access-list 190 allow ip 192.168.7.0 0.0.0.255 192.168.6.0 0.0.0.255

    access-list 190 allow ip 192.168.1.0 0.0.0.255 192.168.6.0 0.0.0.255

    Finally, replace the remote subnet 192.168.7.0/255.255.255.0 192.168.6.0/255.255.254.0 DLINK.

    Hope that helps.

  • Renew the certificate of identity on Cisco ASA 5505, do I have to renew all user certificates?

    n00b questions.

    I have to renew my SSL certificate of identity soon on my Cisco ASA 5505.  I'll have to renew all my certificates for client on their devices, so they can establish a vpn tunnel?

    Hi dsartoros,

    If you encounter a self signed (generated locally) identity certificate renewed, then you will need to download this certificate on the clients so that they can connect without getting "untrusted server certificate error".

    If you renew a certificate issued by a 3rd party CA (sending of CSR to CA) and certificate, then you will not need to make any changes on the client as they already trust the certification authority that issues the certificate first root.

    Kind regards

  • Problems to connect via the Cisco VPN client IPSec of for RV180W small business router

    Hello

    I tried to configure my router Cisco of RV180W as a customer VPN IPSec, but have encountered a problem that I hope someone can help me with. "" I managed to do the work of configuration so that the Cisco's VPN IPSec client authenticates successfully with the XAUTH user, I put on the router, but during the negotiation, the client ends with the following, which appears several times on the router error message: ' Mar 20 Oct 19:41:53 2015 (GMT + 0000): [r1] [IKE] ERROR: local configuration for > [34360] has no config mode.

    I've read around the internet and a number of people seem to say that the Cisco VPN Client is not compatible with the router, but the same thing happens to my iPhone VPN client.

    Is it possible that this can be implemented? Below, I have attached the full configuration files and the log files. Thank you much in advance.

    Correct, the RV180 is not compatible with the Cisco VPN Client.  The Iphone uses the Cisco VPN Client.

    You can use the PPTP on the RV180 server to connect a PPTP Client.

    In addition, it RV180 will allow an IPsec connection to third-party customers 3.  Greenbow and Shrew Soft are 2 commonly used clients.

  • Renew the certificate in Cisco ACS for PEAP authentication

    Hi, we installed in laptops wireless customer a certificate created by Cisco ACS to authenticate, but its about to expire.

    How can I do to renew the certificate whithout affecting users.

    (1) Yes, we can generate a new cert but install the latter.

    (2) install generated new cert on the client.

    (3) install the new cert in ACS.

    Good plan and will probably work.

    Hello

    I think that you need to configure the ACL default PAT so there first statemts 'decline' for traffic that is NOT supposed to be coordinated between the local network and VPN pool

    For example, to do this kind of configuration, ACL and NAT

    Note access-list 100 NAT0 customer VPN

    access-list 100 deny ip 10.0.1.0 0.0.0.255 10.88.0.0 0.0.0.255

    Note access-list 100 default PAT for Internet traffic

    access-list 100 permit ip 10.0.1.0 0.0.0.255 ay

    overload of IP nat inside source list 100 interface GigabitEthernet0/0


    EDIT:     seem to actually you could have more than 10 networks behind the router

    Then you could modify the ACL on this

    Note access-list 100 NAT0 customer VPN

    access-list 100 deny ip 10.0.1.0 0.0.255.255 10.88.0.0 0.0.0.255

    Note access-list 100 default PAT for Internet traffic

    access-list 100 permit ip 10.0.1.0 0.0.255.255 ay

  • Comments Win XP cannot connect to the network when Cisco VPN works on Mac

    Guest OS (Win XP) on the merger connects to the network, no problem. However, when I start a Cisco VPN on my Mac (not in the guest operating system) and then start Fusion/guest OS, the guest cannot connect to the network.

    I was able to use this configuration for a year on an old MacBook Pro (unibody). Last month, I got a new MacBook Pro and flying over my virtual machine image. I don't check for a few weeks. I'm sure I fly over the image correctly because everything else seems OK or if the IT guys doing something to block my traffic over the VPN.

    Config

    -Fusion - Version 3.1.0 (261 058)

    -Mac - 10.6.4

    So far, I have tried the following

    -started to merge and XP without VPN on Mac - OK (bridge autodetect)

    -launched VPN to work, and then launched Fusion - no network

    -tried ipconfig/release, ipconfig / renew - not always no network

    -tried NAT - do always no network

    Thanks in advance. For any help or suggestion will be greatly appreciated.

    Bernie

    The NAT value and then restart the virtual machine.  Works for me with the VPN client built into a cisco router.

    Do not work the real on 10.6.4 cisco software unless you really need to.

  • Routing problem between the VPN Client and the router's Ethernet device

    Hello

    I have a Cisco 1721 in a test environment.

    A net 172.16.0.0/19 simulates the Internet and a net 192.168.1.0/24 simulates the net, the VPN tunnel must go to (intranet).

    The net 172.16.0.0 depends on the router 0 FastEthernet, Intranet (VPN) hangs on Ethernet 0.

    The configuration was inspired form the sample Configuration

    "Configuring the Client VPN Cisco 3.x for Windows to IOS using Local extended authentication"

    and the output of the ConfigMaker configuration.

    Authentication and logon works. Client receives an IP address from the pool. But there's a routing problem

    side of routers. Ping client-side - do not work (the VPN client statistics that count encrypt them packets, but not to decrypt).

    Ping the router works too, but decrypt and encrypt customer statistics in VPN packets count progressive

    (customer has a correct route and return ICMP packets to the router).

    The question now is:

    How to route packets between the Tunnel and an Ethernet device (Ethernet 0)?

    conf of the router is attached - hope that's not too...

    Thanks & cordially

    Thomas,

    Can't wait to show something that might be there, but I don't see here. You do not have the card encryption applied to one of the interfaces, perhaps it was not copied. Assuming your description you do it, or should it be, applied to the fa0 and you are connected. Try how you ping? Since the router or a device located on E0? If you ping the router, you will need to do an extended ping of E0 to the ip address of the client has been assigned. If your just ping the router without the extension, you will get sales and decrypts that you declare on the client. Have you tried to ping from the client to interface E0? Your default route on the router is pointing to fa0? You have a next hop to affect? You have several NIC on the client pc? Turn off your other network cards to check that you don't have a problem with routing on the client if you have more than one.

  • VPN site to Site using the router and ASA

    Hello

    I have a Cisco 1812 router that is configured for remote access VPN using IPSec (Cisco VPN Client), my question is if I can configure a Cisco ASA 5505 to connect to the router as a VPN from site to site.

    Thank you

    Karl

    Dear Karl,

    Yor are right, in this case you can create a tunnel vpn site-to-site between devices or you can configure your ASA as hardware VPN client. That is to say; Easy VPN.

    For the same thing, you can consult the document below.

    Kind regards

  • IP NAT on the router on SSL - VPN appliance

    Someone at - it allows to transmit 443/SSL on a SSL VPN Cisco 891 - K9 unit?

    (I have never encountered this situation before as the router VPN terminated public face directly or we had several IPs public to assign the VPN device directly a public IP address).

    With ' ip nat inside source static tcp 44.55.66.255 443 10.10.10.150 443 extensible "is supposed to pass the SSL request to the appliance SSL VPN to 10.10.10.150 to have VPN applications ended here.

    But failed miserably body 891 - K9 created a virtual ARP entry for 10.10.10.150. So two MACs with the same IP address.

    So 443 requests were sent to its interface. At the hearing of NAT, I can't ssh inside SSL - VPN, but by the time the statemet disappeared, I can ssh and warning dupliacte ARP goes.

    Cisco TAC to reproduce this problem at the moment to report dev.

    Does anyone else have this problem or a workaround?

    Thank you.

    I may be misunderstanding but isn't your NAT statement backwards IE. If you want traffic to pass to 10.10.10.150 it shouldn't be-

    ' ip nat inside source static tcp 10.10.10.150 43 43 44.55.66.25x.

    isn't the device for SSL connection on interface 'ip nat inside '?

  • Roads remain in the routing table after disconnecting from the vpn client

    I am facing this problem for my clients and the easy vpn server.

    My Cisco 3825 has an easy vpn server configuration with an ip pool. When one of the customer disconnects and isakmp and ipsec his deleted by the router itself. The route pointing to the ip address of the ip pool is still in the routing table. This time, another vpn client connects and get the ip address of the ip even pool. But this new vpn client connected is located on a different interface of the router. Thus, an extreme problem happen! A route to 2 next hops is created! So bad!

    Someone else can help me? How can I delete the wrong way?

    Thank you!

    It can be useful to upgrade because he accompanied several questions IPP in earlier versions of the code with the roads not removed during the SA goes down, etc.

  • Bypass the router upstream company ACL with IPSEC VPN

    Hello

    My headquarters has a routing infrastructure company. I want to configure a Site VPN to IPSEC as a solution of webvpn AnyConnect for my users through the company. If the security guys to create an ACL on the router upstream from my Cisco ASA 5585 to allow IPSEC between 28 (the stretch between my external interface of ASA and the trunk of PO on the upstream router) then I can send ip a whole between my inside interface subnet and subnet within the interface on the ASA distant (still on the company's infrastructure holding constant and correct routing. In short, if a packet is encrypted in an IPSEC packet, IPSEC is not filtered, you can send any traffic, even if it is AS restrictive on a router upstream of the LCA, correct?

    Thank you!

    You are right, the router can not look in the VPN package. So anything that is transported inside the VPN, it bypasses security company-ACL.

    For VPN traffic to your ASA, you need the following protocols/ports:

    1. UDP/500, UDP4500, IP/50 for IPsec
    2. UDP/443 for AnyConnect with SSL/TLS, TCP/443
