• Client VPN Cisco ASA 5505 Cisco 1841 router

  Hello. I'm doing a connection during a cisco vpn client and a vpn on one server asa 5505 behind a 1841 router (internet adsl2 + and NAT router).

  My topology is almost as follows

  customer - tunnel - 1841 - ASA - PC

  ASA is the endpoint vpn (outside interface) device. I forward udp port 500 and 4500 on my router to the ASA and the tunnel rises. I exempt nat'ting on the asa and the router to the IP in dhcp vpn pool. I can connect to my tunnel but I can't "see" anything in the internal network. I allowed all traffic from the outside inwards buy from the ip vpn pool and I still send packets through the tunnel and I get nothing. I take a look at the statistics on the vpn client and I 2597 bytes (ping traffic) and there are no bytes. Any idea?

  Where you you logged in when you took the "crypto ipsec to show his"? If this isn't the case then try again, also this option allows IPSEC over UDP 4500 and it is disabled, enable it.

  Just enter the command as it is, then try to connect again after activation of this option and get the same result to see the.

• VPN between 2 1841 router using a connection HDSL

  Hi all

  I need help to solve my problem, sorry for my English, I'll try to explain my problem

  I need to build a VPN (ipsec) between 2 side that use a Cisco 1841 router, each with its own public IP address.

  The side 2 can ping each public IP address but the VPN are DOWN state.

  The schema is the following:

  192.168.1.0/24 (LAN1) <->Ro1 (X.X.X.X) <- vpn="" -="">(Y.Y.Y.Y) Ro2 <->192.168.2.0/24 (LAN2)

  the configuration of the Ro1 is shown on, the same configuration is present also in Ro2, but with a different IP address

• Card crypto applied to the Vlan Interface of the 1841 router

  Currently, our 1841 router has a T1 connected to the WIC T1, Comcast Cable connected to Fa0/0 and the local network connected to Fa0/1.  Tuesday, our 1841 will have an ethernet connection to a new gateway router instead of use the WIC T1.  I added a 4-port ethernet module to the router in the anticipation of this change.  Since the 4-port module is not layer 3 capable, I created a virtual local area network so that I can address the Vlan with the IP address that has been previously configured on the WIC T1.  My goal is to move our IPSec vpn tunnel interface series interface vlan newly created.  I was able to add all orders of the interface vlan, but I wanted to make sure that when the time comes to make the transition, the tunnel will be actually get when it is configured on an interface vlan that is then assigned to one of the four ethernet ports in the add-on.  Has anyone done this or seen that fact?  Potential drawbacks?  Thank you very much!

• Cisco router VPN Failover-

  Hello Experts,

  I have a very simple setup.  I have a Cisco 1841 router with 3 interfaces.  (1eth for LAN, 1eth to ISP2 and 1 eth for isps1).

  I managed to create backup of VPN tunnel using course maps.

  Now, I have to create a failover of VPN with a separate router.  What is the best way to do it?  Examples of configuration would be great.

  This is my setup:

  LAN - firewall-fire-(internal) router (isps1) = Tunnel VPN = VPN - Endpoint1

  |

  |

  |

  (Inside) Router (ISP2) = tunnels2 VPN = Endpoint2 VPN

  So, the trick would be 2 VPN sites on 2 different routers configuration.

  Thank you

  Randall

  Hi randall,.

  Simple. Configure HSRP between 2 routers and create the same configuration on the 2nd router as well. Since the tunnel establish when there is always some interesteing traffic a router will be preferred. Simply connect two routers a switch and the inside interface in the same subnet.

  Here is the link that I could help you

• How to use Layer 2 Ports on the Cisco 1841 router switch

  Hello

  I use the Cisco 1841 router with a single port layer 3 Fe0 and 8 Ports switched.

  I gave the IP on the Fe0 port which is connected to another router.

  Now I don't know how to use Layer 2 of the router switch ports.

  I tried to make one of the port as a Port of access by switchport mode access and connected my laptop and the same subnet given IP, but I can't ping my Fe0 IP port and vice versa, as I am also unable to ping my laptop router.

  Can someone explain to me how to use these ports on layer 2?

• Route VPN site to site on one path other than the default gateway

  I want to route VPN site-to-site on one path other than the default gateway

  What's possible?

  Thank you

  Sorry for my English

  Here is the assumption that I will do:

  -Your IP SHDL is 200.1.1.1, and the next hop is 200.1.1.2

  -Your LAN-to-LAN ends on this interface (interface card crypto SHDL)

  -VPN peer 1 - 150.1.1.1 and LAN is 192.168.1.0/24

  -VPN peer 2 - 175.1.1.1 and LAN is 192.168.5.0/24

  This is the routing based on the assumption above:

  Route SHDL 150.1.1.1 255.255.255.255 200.1.1.2

  Route SHDL 175.1.1.1 255.255.255.255 200.1.1.2

  Route SHDL 192.168.1.0 255.255.255.0 200.1.1.2

  Route SHDL 192.168.5.0 255.255.255.0 200.1.1.2

• Static and NAT router to router VPN

  Hello

  I have two site VPN using routers. The VPN is fine, BUT - at the end of the seat, the customer has NAT entries static to allow incoming connections - any service that has a NAT static to allow incoming connections from the Internet is inaccessible in the same way. Ping, for example, doesn't have this problem because there is no static NAT entry. I tried to configure a route map-"No. - nat" according to the http://www.cisco.com/en/US/partner/tech/tk583/tk372/technologies_configuration_example09186a00800949ef.shtml , I thought I was working.

  H.O. has the IP 131.203.64.0/24 and 135.0.0.0/24 (I know, I know - I'm trying to change), and the R.O. 192.168.1.0/24.

  Bits of configuration:

  IP nat inside source overload map route SHEEP interface Ethernet0

  IP nat inside source static tcp 135.0.0.248 131.203.100.27 3389 3389 extensible

  (other static removed)

  Int-E0-In extended IP access list

  ip permit 192.168.1.0 0.0.0.255 any

  (other entries deleted)

  access-list 198 deny ip 131.203.64.0 0.0.0.255 192.168.1.0 0.0.0.255

  access-list 198 deny ip 135.0.0.0 0.0.0.255 192.168.1.0 0.0.0.255

  access-list 198 allow ip 135.0.0.0 0.0.0.255 any

  SHEEP allowed 10 route map

  corresponds to the IP 198

  1 remove the static entry for the specified host the VPN problem, but obviously breaks things :(

  2. as mentioned, the VPN itself works fine, I can ping hosts perfectly.

  Any help greatly appreciated :)

  Thank you

  Mike.

  You must use the option of the route to the static NAT map. This is a new feature in 12.2 (4) T according to this page:

  http://www.Cisco.com/univercd/CC/TD/doc/product/software/ios123/123cgcr/ipras_r/ip1_i2g.htm#1079180

  He must do exactly what you want. The old, another way to do is use "The thing", where you create a loopback interface and don't make a nat interface and use routing strategy for routing VPN traffic to one address on the same subnet as the loopback interface, but not the address of the loop. IOS then that réacheminera traffic to the real destination (in this case the remote VPN site), but since now it is not a 'ip nat inside' interface, the static nat translations does not apply and the VPN traffic will not be translated. The problem with this solution is that all loopback traffic is switched to the process, so it is a bit of a hack, but these things are sometimes necessary.

• IOS router + VPN + ACS downloadable IP ACL

  I want to use the function "Downloadable IP ACL" 3825-router VPN (OI 12.4 T) in combination with a CBS.

  In many documents and discussions, I read that it is possible to use the DACLs on "devices Cisco IOS version 12.3 (8) T or higher.

  Authentication and authorization by the AEC works and the device gets some settings of the av-pair-feature.

  I have tried several things to apply the DACL as the use of av pairs or ACS "Downloadable IP ACL" function, but nothing works.

  In the debug log, I see that the av pair is transmitted to the device, but it is not used.

  --> Can you tell me, is it possible to use the DACLs on the IOS routers?

  --> How does it work? What can I change?

  --> Is there a good manual to apply it?

  Thanks for your help!

  Martin

  It would be useful to know the PURPOSE of what you're trying to do...

  AFAIR client config mode requires no ACL for filtering short tunnel split ACL... and I have no way to test right now.

  If you want to allow or not some clients access to certain subnets why not investigate tunneling ACL and vpn-filter in combination with ACS split will rather than for the DACL.

• Unusual routing VPN configuration

  Hi, I use a PIX 525 to our main site, and one of the remote sites using a router in 1721. The 1721 connects to the LAN. All traffic is forced to use a virtual private network between the remote sites and main. The intention was to force the internet traffic from the remote site through the filter of content on the main site, rather than use the split tunneling to leave straight out to the internet through their DSL connection.

  The problem is that, of course, internet traffic this VPN comes back the PIX, Internet. Our content filter reflects the way of the switch connected to the internal interface of a PIX.

  I need to find a way to route VPN traffic from the remote site to an ethernet on the PIX interface which will be connected to our switch stack. If I can do this without breaking the VPN, traffic should be filtered on the main façade and through VPN to the remote side.

  Yes, you're pretty much toast unless:

  you choose to configure a web proxy to Headquarters and set up remote PCs to use it. In this way, they use a proxy that is located behind the 8e6.

  Same pix os 7 will not help, as all nat occurs on this topic - just remote communication will flow through the pix, never hit its physical interface or internal switch ports inside and so the 8e6.

  Please help, how to set up vpn?

  Hello

  According to this output is more than clear that you do not have a k9 license applied to this router, this license will enable the security features on your IOS, in this case, you will need a permit of k9 with an activation key, and then you will be able to have available on your device encryption controls. Once you have that we can work on configuring site to site.

• Download ACL for VPN users. ACS 4.1 &amp; 1841 router

  Hello

  I have configured the router 1841 as a VPN server. All VPN users get authenticated using RADIUS ACS 4.1

  I need to apply downloadable ACLs by user.

  I configured the Downlodabale ACL ACS. Same ACS event report shows that the ACL is applied to the authenticated user, but traffic is not blocked or past accordingly.

  What is your configuration?

  I think that the more easy to do is to use IPSEC TIV in interfaces, as well as the aaa authorization network and on the radius server, use ip:inacl to the cisco av pair, as

  IP:inacl #1 = permit tcp any any eq 80

  IP:inacl #2 = permit tcp any any eq 443

• IPSEC VPN between Pix 515E and 1841 router

  Hi all

  BACKGROUND

  We have implemented a site to site VPN IPSEC between a Pix 515E 8.0 operation (4) and an 1841 using static IP addresses at both ends. We used CCP on the router and the ASDM the pix to build initial tunnels. Now the site with the router is evolving into a dynamic IP address from the ISP so we have implemented dynamic DNS to update dynamic IP address.

  PROBLEM

  The problem is that ASDM will not allow us to set a domain as the address of peers, it will not accept an IP address. We believe that the solution will be to remove the static Crypto map and replace it with a dynamic Crypto map on the side of Pix. Our questions are simply; is this the best solution? can change us the original static list or is it better to delete and make a new dynamic encryption card? Y at - it a shortcut to change the config command-line? This is a real network, so just check it out before make us any changes on the live kit.

  Any help much appreciated.

  You don't have to change anything when the peer-address changes. The dynamic crypto map aims to take dynamic peer connections. The only thing to remember, is that only the dynamic peer can initiate the connection. And you reduce your security if you use Pre-Shared key that now you can use a generic-PSK character.

  As I remember, the PIX / ASA does not support the dynamic use of FQDNs for peer-resolution. This feature is supported in IOS.

  For a feature, it would be preferable to static IP addresses on both sides.

• IOS router VPN Client (easy VPN) IPsec with Anyconnect

  Hello

  I would like to set up my router IOS IPsec VPN Client and connect with any connect.
  Is it possible to configure an IPSec and SSL VPN Client on IOS router? I use for example a 1841.

  It would be perfect to give the user the choice of SSL or IPSec protocol. And the user needs that the Anyconnect Client.

  I think it's possible with a Cisco ASA. But I can also do this with an IOS router?

  Please let me know how if this is possible.

  Also is it true that the IOS routers are not affected to hear bug bleed? SSL VPN and SSL VPN with Anyconnect page is also save?

  http://Tools.Cisco.com/Security/Center/content/CiscoSecurityAdvisory/CIS...

  But I am in any way interested in using IPSec and SSL VPN on a router IOS...

  It's true - CCP does not yet offer the options to configure a VPN IPsec with IKEv2.

  The configuration guide (here) offers detailed advice and includes examples of configuration.
