Cisco 881 - maximum number of VPN tunnels allowed?

Hello

I know it sounds simple and easy question, but I can't find the answer anywhere - so here it is: -.

I need to know the maximum number of vpn tunnels that can manage a Cisco 881.

(In the context, we have a group of users who work from home and office, so their laptops have the cisco vpn client, I need to know how much of these vpn connections the 881 can manage both before, he died a death)

Host-, I read somewhere a line that State maximum number of users is 20 but believe it was referring to a VOIP service.

Thanks in advance.

The 881 supports 20-tunnel IPSec:

  • Question of access list for Cisco 1710 performing the 3DES VPN tunnel

    I have a question about the use of access lists in the configuration of a router Cisco 1710 that uses access lists to control traffic through the VPN tunnel.

    For example the following lines in a configuration on the remote router. My question is whether or not the traffic that matches the definition of list access-130 (something other than 192.168.100.0/24), cross the VPN tunnel or go directly to the Ethernet0 interface.

    My understanding is that traffic that matches the access list 120 would be encrypted and sent through the IPSec tunnel. If there was "ban" set out in the statements of 120 access-list, the traffic for those would be sent through the IPSec tunnel but not encrypted (if possible). And finally, given that the definition of crypto card reference only "adapt to 120", any traffic that matches 130 access list would be sent Ethernet0 but not associated with the card encryption and thus not sent through the IPSec tunnel. "

    Any input or assistance would be greatly appreciated.

  • Impossible to achieve secondary with VPN tunnel

    Hello

    I configured a Cisco Pix Firewall to my VPN tunnels and which works fine when I connect to the local network where the Pix is connected.

    When I want to communicate with a server on a secondary location over the vpn tunnel I get no response.

    The pix can ping the server, but I can't ping the server via the vpn tunnel rooms

    PIX from IP 10.1.0.254

    Router 10.1.10.254 IP address

    Secondary router IP address 10.2.10.254

    Secondary server IP address 10.2.0.1

    The default gateway on the local network is 10.1.10.254

    This router is a gre tunnel 3 of to 10.2.10.254

    On this router, there is a default route for the pix (for internet).

    Hello...

    Make sure that you send the IP pool configured on the PIX of the secondary router/server. just try to ping the IP address that the VPN client is obtained from the server...

    You must also make sure that you add this subnet secondary access sheep... otherwise list your ip pool will see the natted IP server...

    on sheep access list, allow all traffic from the pool of secondary for the IP pool...

    I hope this helps... all the best...

  • Routing access to Internet through an IPSec VPN Tunnel

    Hello

    I installed a VPN IPSec tunnel for a friend's business. At his desk at home, I installed a Cisco SA520 and at it is remote from the site I have a Cisco RVS4000. The IPSec VPN tunnel works very well. The remote site, it can hit all of its workstations and peripheral. I configured the RVS4000 working in router mode as opposed to the bridge. In the Home Office subnet is 192.168.1.0/24 while the subnet to the remote site is 192.168.2.0/24. The SA520 is configured as Internet gateway for the headquarters to 192.168.1.1. The remote desktop has a gateway 192.168.2.1.

    I need to configure the remote site so that all Internet traffic will be routed via the Home Office. I have to make sure that whatever it is plugged into the Ethernet on the RVS4000 port will have its Internet traffic routed through the Internet connection on the SA520. Currently I can ping any device on the headquarters of the remote desktop, but I can't ping anything beyond the gateway (192.168.1.1) in the Home Office.

    Any help would be greatly appreciated.

    Thank you.

    Hi William, the rvs4000 does not support the tunnel or esp transfer wild-card.

  • Site to site VPN works only on Cisco 881

    I have 2 problems with a cisco 881. The first problem is that Vlan2 (192.168.5.xx) cannot access the internet on the outside. But I know that the router has internet, because I can ping the external ip address. The 2nd problem is that I have a set of site to another upward, but when I test the Site to site I get this error:

    destination of traffic of the tunnel must be channelled through the crypto map interface. The destination following (s) doesn't have a routing entry in the routing table
    192.168.2.0

    I copied the config form this router from another cisco 881 work, where everything works. The only difference is that this router needs a site to site vpn connection.

    My question is how I can get internet on vlan2 and who can I solve the connection to site to site.

    Here's the running configuration:

    It seems that DNS has failed, because it is indeed happened to internet, but it does not work when internet DNS resolution.

    Go ahead and try to ping this 157.166.226.25, and it's on the browser http://157.166.226.25/, CNN.com. Let's try those. Also just in case where to configure a DNS SERVER on your router.

    - http://www.cisco.com/c/en/us/support/docs/ip/domain-name-system-dns/2418...

    Disable any ZBF just in case.

  • Support VPN Cisco 881

    Hi all

    I am not cisco trained or worked with cisco, im a complete beginner in Cisco platforms. We are an IT support MPH and we have recently taken on a client that has an office abroad using a Cisco 881 device with a Draytek router to the United Kingdom. Site to site connectivity is necessary. I watched and watched videos of youtube on how to configure the VPN and think I have it in place by using the config on the cisco below:

    crypto ISAKMP policy 1
    BA 3des
    preshared authentication
    Group 2
    lifetime 28800
    isakmp encryption key * address *.
    !
    Crypto ipsec transform-set esp-3des esp-sha-hmac sha3des
    !
    crypto map 1 VPN ipsec-isakmp
    set peer *.
    Set transform-set sha3des
    PFS group2 Set
    match address UK

    !

    interface FastEthernet4

    IP access-group netbios on

    IP virtual-reassembly in

    no ip route cache

    VPN crypto card

    !
    interface Vlan1

    IP access-group netbios in
    IP access-group netbios on

    IP nat inside
    IP virtual-reassembly in
    no ip-cache cef route
    no ip route cache
    !

    UK extended IP access list
    allow IP 0.0.0.255 0.0.0.255
    allow IP 0.0.0.255 0.0.0.255

    It shows the VPN and active but there is no movement between the two and I do not know why...

    Current state of the session crypto

    Interface: FastEthernet4
    The session state: UP-ACTIVE
    Peer: port of 500
    IKEv1 SA: local remote 500 500 Active
    FLOW IPSEC: ip allow /255.255.255.0 /255.255.255.0
    Active sAs: 0, origin: card crypto
    FLOW IPSEC: ip allow /255.255.255.0 /255.255.255.0
    Active sAs: 2, origin: card crypto

    So it all seems perfect, however, if I try and ping the remote remote sites over ip LAN router I get the following:

    Type to abort escape sequence.
    Send 5, 100 bytes to ICMP echoes, waiting time is 2 seconds:
    .....
    Success rate is 0% (0/5)

    I also can't ping the remote site in the Cisco lan.

    I think that it is towards the end of cisco, the Draytek is a basic router and no routing is able to be configured. It does it automatically. The VPN is so no traffic...

    Please can someone point me in the right directoin?

    Thank you

    The additional ip route does not harm even if it is not needed. I love these additional routes that they can serve as a sort of "online documentation" when it is used with a keyword "name" extra at the end.

    Your NAT - ACL does not have the traffic. Just add the following:

     ip access-list ext 102 1 deny ip  0.0.0.255  0.0.0.255 

  • VPN tunnel between the concentrator 3005 and router Cisco 827

    I am trying to establish a VPN tunnel between the Central Office with VPN 3005 and controller branch Cisco 827 router.

    There is a router of perimeter with access set up in front of the 3005 list.

    I quote the ACLs on the Central perimeter router instructionsuivante to allow traffic to permit ip 3005 - acl 101 all 193.188.X.X (address of the hub)

    I get the following message appears when I try to ping a local host in the Central site.

    Can Anyoune give me the correct steps to 827 and 3005.

    Thank you

    CCNP Ansar.

  • Allowing ports through a VPN tunnel question

    I have a VPN tunnel established and I can ping above but my application fails and I think its because I encouraged not 2 ports (ports TCP 19813 and 19814) through. I'm not clear how should I do for allowing these ports through. I need to add a statement to permit to access my list 'sheep' or what I need to add a statement of license to my list of access interface "external"?

    Remote users have an IP address of 172.16.5.x 24 and they're trying to connect to users on the 192.168.200.x 24 192.168.201.x 24. I can't do a ping of the 24 192.168.200.x to the 172.16.5.0/24.

    The commands below are what I currently have in my PIX.

    My current sheep-access list:

    IP 192.168.201.0 allow Access-list sheep 255.255.255.0 172.16.5.0 255.255.255.0

    IP 192.168.200.0 allow Access-list sheep 255.255.255.0 172.16.5.0 255.255.255.0

    My current outside of the access-list interface:

    acl_inbound list access permit tcp any host xx.xx.xx.xx eq smtp

    acl_inbound list access permit tcp any host xx.xx.xx.xx eq - ica citrix

    acl_inbound list access permit tcp any host xx.xx.xx.xx eq www

    acl_inbound list access permit tcp any host xx.xx.xx.xx eq www

    acl_inbound list access permit tcp any host xx.xx.xx.xx eq www

    acl_inbound list access permit tcp any host xx.xx.xx.xx eq 500

    acl_inbound esp allowed access list any host xx.xx.xx.xx

    acl_inbound list access permit icmp any any echo response

    access-list acl_inbound allow icmp all once exceed

    acl_inbound list all permitted access all unreachable icmp

    acl_inbound list access permit tcp any host xx.xx.xx.xx eq www

    acl_inbound list access permit tcp any host xx.xx.xx.xx eq https

    first of all, you disable the commnad "sysopt connection permit-ipsec" on the pix? with this enabled command, which is enabled by default, the pix will ignore any ACLs for encrypted traffic. so if you have Hell no this command, then the acl that you applied on the outside int won't make a difference.

    However, if "sysopt connection permit-ipsec" is always on, and then all the port/protocol should be allowed.

    you said you could do a ping of 192.168.200.0 to 172.16.5.0. How about you 172.16.5.0 to 192.168.200.0 and 192.168.201.0?

    also, just wondering if the vpn lan-to-lan or access remote vpn (i.e. using the cisco vpn client).

  • Cisco 1921 - how to configure VPN multiple Tunnels to AWS

    I have a router VPN Cisco 1921. I managed to create tunnel VPN Site to Site with AWS VPN Tunnel 1. AWS offers 2 tunnels, so I created another card Crypto and attaches to the existing policy. But the 2nd tunnel won't come. I don't know what I'm missing... is there a special setup that needs to be done to allow multiple IPsec vpn tunnels on the same physical interface? I have attached a picture and included the configuration of my router, if it helps.

    There should be no second tunnel.

    I use either a peer or the other, but not both at the same time.

    To display both at the same time, you need to use the Tunnel interfaces.  Amazon would have you sent pretty much the exact commands to copy and paste into.

    Good news, that VPN has been implemented!

    According to the ping problem, my suggestion is to check, if some type of firewall based on host computers on both sides block ICMP requests.

    Anyway, you can still use the capture of packets on the inside of the interfaces of the two ASAs, to check if the ICMP traffic is to reach the ASA.

    In addition, you can try to enable ICMP inspection:

    Policy-map global_policy
    class inspection_default

    inspect the icmp

  • Interpret what is allowed on the VPN tunnel

    Hello

    I work with Cisco PIX equipment for the first time and I'm trying to understand what is allowed on one of the VPN tunnels which are established on the PIX.

    I interpret this PIX did by reading the running configuration. I was able to understand most of it (with the help of the cisco site), so I'm starting to get comfortable with it. I'm looking for more help in the interpretation of what is allowed by a good VPN tunnel. Here are some details:

    map Cyril 2 ipsec-isakmp crypto

    Cyril 2 crypto card matches the acl-vpntalk address

    access list acl-vpntalk allowed ip object-group my_inside_network 172.17.144.0 255.255.255.0

    So, if I interpret it correctly, then the traffic matching ACL acl-vpntalk will go on the VPN tunnel.

    As far as the lists others access dedicated, my inner interface I have:

    Access-group acl-Interior interface inside

    With ACL-Interior:

    access list acl-Interior ip allow a whole

    So nothing complicated there.

    Now, just because of all this I conclude I encouraged all remote network traffic in my site. If all traffic 172.17.144.0/24 is allowed to join my network.

    However, I don't know if this conclusion is correct.

    This ACL is also applied:

    Access-group acl-outside in external interface

    And it looks like:

    deny access list acl-outside ip a

    I'm not sure if this ACL applies to vehicles coming from the IPSEC peer. It's for sure inbound on the external interface, but if it is valid for the IPSEC traffic I don't know.

    If it is valid, then am I had reason to conclude that only connections initiated from my inside network to the remote control can come back?

    Thanks in advance for your ideas.

    With sincere friendships.

    Kevin

    Hey Kevin,

    Here are my comments, hope you find them useful:

    1. the ACL called "acl-vpntalk" sets traffic who will visit the IPSec tunnel, so you got that right. All traffic from the group called "my_inside_network" will 172.17.144.0/24 will pass through the tunnel, and there should be a similar to the other VPN end opposite ACL.

    2. the 'acl-inside' applied to the inside interface allows any ip traffic coming out of the isnide to any destination.

    3. the 'acl-outside' rejects all traffic from entering your home network, but the IPSec traffic is free and will cross because you will find a "sysopt connection permit-ipsec' configured on your PIX command that tells the operating system to allow all traffic destined for VPN tunnels without explicitly enabling it through the inbound ACL. If you have stopped the "sysopt" should stop your traffic and you will have more control on your tunnel traffic.

    Personally, I usually disable the "sysopt" and control the VPN traffic in my incoming ACL.

    Just a quick note, if you look more deeply into the ACL on the PIX functionality, you will find that no traffic moves inside, if she is not allowed on the external interface. For example, you can allow traffic between "inside" and "dmz" interfaces by adding an entry 'allow' on one of the ACLS applied to one of these interfaces. But when you want to allow traffic from the external interface (security level 0), you will need to allow in the inbound ACL applied on the external interface.

    I could have written something vague, but I hope you get my point.

    Thank you.

    I have a friend who asked me to try to help.  We are established VPN site to site with a customer.  Our camp is a Cisco sa520 and side there is a control point. The tunnel is up, we checked the phase 1 and 2 are good. The question is through the tunnel to traffic, our LAN ip address are private addresses 10.10.1.0/24 but the client says must have a public IP address for our local network in order to access that server on local network there.  So, in all forums, I see that you cannot NAT before crossing the VPN tunnel, but our problem is that our site has only 6 assigned IP addresses and the comcast router, on the side of the firewall SA520 WAN.  So we were wondering was there a way we can use the WAN on the SA520 interface or use another available 6 who were assigned to the NAT traffic and passes through the tunnel.  That sounds confusing to you?  Sorry, but it's rarely have I a customer say that I must have a public IP address on my side of the LAN.  Now, I say this is a SA520 firewall, but if it is not possible to do with who he is a way were able with an ASA5505?

    Help or direction would be very useful.

    Hello

    I guess I could quickly write a basic configuration. Can't be sure I remember all correctly. But should be the biggest part of it.

    Some of the course settings may be different depending on the type of VPN L2L connection settings, you have chosen.

    Naturally, there are also a lot of the basic configuration which is not mentioned below.

    For example

    • Configurations management and AAA
    • DHCP for LAN
    • Logging
    • Interface "nonstop."
    • etc.

    Information for parameters below

    • x.x.x.x = ASA 'outside' of the public IP interface
    • y.y.y.y = ASA "outside" network mask
    • z.z.z.z = ASA "outside" IP address of the default gateway
    • a.a.a.a = the address of the remote site VPN L2L network
    • b.b.b.b = mask of network to the remote site VPN L2L
    • c.c.c.c = IP address of the public peer device VPN VPN L2L remote site
    • PSK = The Pre Shared Key to connect VPN L2L

    I hope that the above information was useful please note if you found it useful

    If it boils down to the configuration of the connection with the ASA5505 and does not cut the above configuration, feel free to ask for more

  • Cisco 1841 how vpn tunnels? default 100vpn?

    Hi everyone, I have read the previous posts and I read that the cisco 1841 can manage up to 100 default VPN tunnels.

    1. is this true?  (I enclose my worm of show)

    2. this version of IOS support SSL VPN tunnels as well?

    Hello

    I guess that means that the total number of vpn ipsec tunnels taken in charge by the router of SSL VPN AIM is 800.

    If you want only a SSL VPN without the AIM module can it be based on the license.

    Kind regards

  • Transfer between Cisco ASA VPN Tunnels

    Hi Experts,

    I have a situation where I need to set up the transfer between two VPN Tunnels completed in the same box ASA. A VPN Tunnel will incoming traffic and that traffic should be sent to the bottom of the other VPN Tunnel to the ASA. The two VPN Tunnels are from the Internet and speak with the same IP address of the ASA peers.

    Retail

    Tunnel A

    Source: 192.168.1.0/25

    Destination: 10.1.1.0/25

    Local counterpart: 170.252.100.20 (ASA in question)

    Remote peer: 144.36.255.254

    Tunnel B

    Source: 192.168.1.0/25

    Destination: 10.1.1.0/25

    Local peer IP: 170.252.100.20 (box of ASA in question)

    Distance from peer IP: 195.75.75.1

    Can this be achieved? what configurations are needed in the ASA apart cryptographic ACL entries?

    Thanks in advance for your time.

    Believed that, in this case your config is good, and you can avoid using routes on your asa since it must route based on its default gateway, make sure you have good sheep in place rules and the inter-to interface same-security-interface allowed return you will need.

  • Cisco 881 - Access Gateway VPN session

    Nice day

    I configured my Cisco 881 and finally has surpassed "thecan't see my network" issue IPSec VPN.

    I have a usecase where I need to access the gateway of the VPN Session.

    When I connect to the VPN using Cisco VPN Client 4.8 x, I do not return a default gateway on the VPN map. When I try to ping my IP from the LAN (10.20.30.1) bridge that does not work and I cannot access it with other tools.

    I'm sure it's an ACL question and it makes sense to hide the default gateway, but the big question is how to configure my router to see the gateway and access them from the VPN session?

    Please see my attached cleaned configuration.

    Network Info:

    • Internet Internet service provider gateway: 192.168.68.1
    • DNS: 192.168.2.1
    • Address WAN Cisco 881 at: 192.168.68.222
    • Address on Cisco 881 LAN: 10.20.30.1
    • DHCP for LAN on Cisco 881: 10.20.30.10 - 10.20.30.50
    • DHCP for IPSec VPN: 10.20.40.10 - 10.20.40.50

    Thank you in advance for your help!

    Kind regards
