Cisco VPN :: Setup L2L IPSec VPN Between VPN3020 Concentrator And 2811?
Feb 22, 2011
I am trying to setup a L2L IPSec VPN between cisco VPN3020 concentrator and Cisco 2811 something is not working and I don't understand why.I describe my situation in detail my router has 2 interfaces
External interface Fa 0/1 ip 193.P.Q.R
Internal interface Fa 0/0 141.G.H.254
Lan on internal interface is 141.G.H.0/24
remote VPN concentrator has 2 interfaces
Public interface 131.A.B.C
Private interface 131.A.I.E
I have to set up L2L so that host 141.G.H.10 can talk to host 131.A.H.D whici is behind the VPN concentrator my router config:
crypto isakmp policy 3 encr 3des hash md5 authentication pre-share group 2crypto isakmp key * address 131.A.B.C!crypto ipsec transform-set presid-set esp-3des esp-md5-hmac !crypto map presid-map 5 ipsec-isakmp set peer 131.A.B.C set transform-set presid-set match address presid!interface FastEthernet0/1 ip address 193.P.Q.R 255.255.255.252 duplex full speed 100 crypto map presid-map!interface FastEthernet0/0 ip address 141.G.H.254 255.255.255.0 duplex auto speed auto!
ip access-list extended presid permit ip host 141.G.H.10 host 131.A.H.D
ip route 0.0.0.0 0.0.0.0 193.P.Q.S
Then I configured VPN3020 accordingly creating a lan to lan profile with the proper IKE proposals ecc ecc when interesting traffic is matched by VPN acl (presid) I see this messages in the VPN concentrator logs:

and from router side I See this with show crypto isakmp sa
131.A.B.C 193.P.Q.R CONF_XAUTH 5 0 ACTIVE
but the status got stuck in CONF_XAUTH state and then disconnects?
We have to setup an IPSEC tunnel for a client that does not what to exchange private IP address information for security and overlapping address space reasons. We will both be natting our source private ip address space as public IP address space and send those packets through the established tunnel. Im using a Cisco 3000 concentrator.
I have been trying to setup a LAN-to-LAN VPN between two sites that are using a 3000 series CISCO Concentrator. After following the basic setups from the CISCO site, I am still unable to create a tunnel. At the moment I'm starting to believe it is how I have physically setup the network. Site 1 is using a Billion BiPAC 7404VNPX ADSL2+ Modem, Site 2 is using a Netgear DGN2000 ADSL2+ Modem, The VPN Concentrators are setup behind these devices with each firewall setup to allow the needed ports forwarded.
I've the following scenario VPN Concentrator is connected to a router which is connected to a router and at the edge Cisco 515E PIX is connected to the internet. The problem is that the normal VPN Dial-up connection (a utility of windows) are getting connected but Cisco VPN Client throws error 412. Here's what I've tried (Initially groups and user were created):
(1) Allowed port 10000 on PIX ( access-list from-outside-coming-in permit tcp any host <public ip> eq 10000) and checked IPSec over UDP on VPN Conc. under Mode Config tab. Also checked IPSec over TCP tab under tunneling panel at port 10000. Tried connecting through VPN Client but it threw error 412 (2) In the reference guide, I read that IPSec over NAT is allowed on ports ranging from 4000 something to 40000 something.
I tried 33333, both on PIX and VPN Conc. under Mode Config tab but still no use. Same error 412.
We have a remote office that needs to be connected to the central office through a site to site ipsec VPN.At the central site there is a 2811, and at the remote site there is 1841.Most of the traffic will be VoIP traffic and small amounts of data.
I need to setup some QoS that would firstly prefer the VPN traffic over internet access and then inside the VPN I need some QoS that will preffer VoIP over data.
I am having problems with CPU load on 2811 with AIM-VPN-II. There is a GRE+IPSec over E3 WAN link and the authentication is done using RSA, but even that there is around 10Mb/s of traffic I have a 70 - 85%. I also have another WAN link with router 2811 that doesn't have a AIM-VPN, and that one reach 95% CPU once the traffic goes up to 5 Mb/s.
Are there any recommendations that RSA authentication is not supportted for hardward encryption? It worries me, becouse have more sitautions like this.
I have a 2811 that is my HQ router with a 10MB pipe. I was trying to configure a IPSEC tunnel to connect to my ASA that has access to our companies internal servers on the 10.33. and 172.16.31 network. I am having a problem getting phase 1 to even come up. I've looked over the configurations and unless i'm overlooking something I dont see what could be keeping it from at least completing phase 1
Below are the configs. 2811-CFG crypto isakmp policy 10 encr 3des hash md5 [Code] ....
I am trying to get a 2811 to accept two IPSec peers however can only get one working at a time. I have setup fa0/0 and fa0/1 with their own public facing IP addresses with crypto maps associated to each interface however can only establish connectivity to one interface at any one time.
I'm now trying to implement a IPsec VPN network over transport mode in my simple network environment.I got two Cisco 2811 routers connected each other and each router hosts a client PC running Windows7.
I have finished the configuration on both routers and make them running over transport mode.However, as what it should be, transport mode indicates the communication between two end stations (two PCs) the client PC (install or configure something) to make the network fully works?
My router is Cisco 2811 with IOS version 12.4(22)T1. It had established IPSec with another peer (203.*.*.250 shown below) for long until recently we make it re-establish IPSec VPN with another peer (203.*.*.30 shown below). It showed that the new sa is active but the result still showed there were 4 deleted SAs. The 4 obsolete sa entries won't vanish no matter what I do i.e. reset the interface, re-create crypto map, clear all sa and etc.
From numerous testings we knew that the VPN doesn't work even the desired sa is there remaining active. I reckon it has something to do with those deleted sas ( i mean it is supposed to show only the last one if it is working fine ). I don't know how it would be come like this as we did pretty much the samething on other VPN routers with no problems.
setting up IPsec for a DMVPN between a 2811 and 2951s in a test lab. I have enabled IPsec on the hub (2811) but I am unable to do so on either of the 2951s. After researching, it seems that I may have the incorrect IOS for this, but I am at a loss which IOS I should be using. Currently the 2951s are on "c2951-universalk9-mz.SPA.151-2.T2.bin" and the only crypto options are(config)#crypto ?
ca Certification authority key Long term key operations pki Public Key components
while on the 2811 I get:
WIN-T(config)#crypto ? ca Certification authority call Configure Crypto Call Admission Control ctcp Configure cTCP encapsulation dynamic-map Specify a dynamic crypto map template engine Enter a crypto engine configurable menu gdoi Configure GDOI policy
i have a branch router that connects to mpls WAN. Also has a second interface that is used for dmvpn failover in case WAN goes down.We want to use this second interface also as the primary internet circuit for the branch. I changed the default route to the next hop address on the other side of the second interface and expected this to work.But i was told i need to set up NAT for this to work, and set up an ACL for NAT to use. how to set up NAT?
I've setup a NTP service by using Cisco 2811 routers. This works fine at the moment, but in the end there are some questions left.
1. I'm using two 2811 Routers, one for primary, which is resceiving the time from PUBLIC NTP 1, and one for backup, which is resceiving the time from PUBLIC NTP 2. Is it possible to compare these to times an check if the match? And if not, generate an alarm via e.g. SNMP
2. Is it possible to check via SNMP, if the routers are reaching PUBLIC NTP 1 and PUBLIC NTP 2 for sync?
I'm trying to setup a SSL VPN on a 2811. I believe I have the SSL VPN portion understood, but I can't tell because I keep getting stuck on the Certificate Server, ca trustpoint and identity trustpoint configuration.
guide that walks you through the CA cert, Cert Server, ca trustpoint and identitiy trustpoint to ios SSL VPN?
I am pretty new to the configuration of a DMZ and I have the task of setting one up.I have a Cisco 2811 Router running Cisco IOS Software, 2800 Software (C2800NM-ADVENTERPRISEK9-M), Version 12.4(24)T1, RELEASE SOFTWARE (fc3), 2 FE interfaces.One FE is connected to the WAN, with a loop back interface configured with the public IP for Internet access in the office.The other FE has 2 sub interfaces configured, one for data and the other for voice traffic.Users within the office are configured to use the data VLAN to access the internet through the WAN.
Now we are setting up some new services and we require to have DMZs setup.I want to setup 3 zones now that the different servers would reside in. How can i achieve this using the existing infrastructure I have?I have an idea to create more subinterfaces and assign them to the zones, but I am still not sure how this would play out. I have been on this for the whole day and unable to make significant progress.
I am lacking experience in BGP and now I am trying to figure out what should be the ideal and recommended design.
Scenario: - Having two Internet Service Provider with two ASN - Having one idenpendant IPv4 public address - Having two Internet Cisco Router e.g. 2811 - Having two Cisco ASA Firewall e.g. 5510
I got connected ASA ----- ROUTER 2811) to metroethernet switch from my ISP , with a 4MB of bandwidth but the internet connections to all my LAN has been frozen and we lost connection to the internet, to restart the internet service I need to boot the ROUTER 2811 - and ISP switch to rollback the internet operation,My ISP support tell me if is possible to set up the traffic bandwidth in one or both borders devices, ( ASA 5510 or ROUTER 2811)
I have a asa and Cisco 2811, needs to build a site-to-site ip sec tunnel between them. Due to a requirement need to encrypt inside traffic, i need to apply on the inside interfaces on both devices to build the tunnel.
I don't see a problem but just want to check if it would work on terminating on Inside interfaces on both ip sec peers.
I would like to set up a POTS Dial connection between 2 Cisco routers, using the modem card WIC-1AM-V2. I'd like to use this as an out-of-band connection to a remote site, if the primary internet connection fails. So, this setup will only be used in one direction, 1 router placing calls, the other one receiving calls.Here's my config of the receiving router:
chat-script dial "" ATZ AT OK "ATX3D T" ATS0=8 TIMEOUT 120 CONNECT C interface Async0/2/0 description out of band for network no ip address encapsulation slip async mode interactive line 0/2/0 session-timeout 5 absolute-timeout 10 script connection dial login local modem InOut transport input all escape-character BREAK autoselect ppp stopbits 1 speed 115200 flowcontrol hardware
[code]....
This config is working fine, when dialing in via a Windows Hyperterminal Dial connection. After a while of dialing I get the login prompt of the router.Now I want to have a router placing calls instead of a Windows Server. I can't figure out how to tell a router to place calls to a POTS phone number.
We're in the process of setting up an ASA 5510 as our main VPN appliance.
The Outside interface of the 5510 faces our DMZ, the Inside interface sits on our main network. The 5510 uses radius for authentication going to a server on the same subnet for the authentication. That works fine. VPN client can connect to the 5510 and successfully authenticate. Routes are pass through to the VPN client, no problem. PC with VPN client can access internet (which is by design, it should use it's own internet connection), but cannot ping/access/trace over the tunnel at all.
My hunch is that this is a nat issue - but I am confused as to how the NAT should be configured - I've tried several configurations with no luck.
The VPN client is set to pull an ip address from the pool - 192.168.56.10 - 100. The 5510 is sitting on a separate subnet (50.x/22). This seems to work on the Cisco 1700 that it will be replacing just fine. I mirrored routes and ACLs as well onto the new 5510. No luck. Client connects, authenticates, pulls an IP address and routes, but can't see anything on the inside of the 5510.
I'm having trouble setting up a second IPSec VPN tunnel on my Cisco ASA 5505 to another office. I was able to setup the first one with no problem through the ASDM, but have not been able to get the second one up.The IPSec tunnel is connecting to a WRVS4400N router at the other office. I tried debugging crypto isakmp, and crypto ipsec, but I'm getting nothing. Below is the config. Does something look wrong on my end? I also attached a screenshot of the parameters setup on the remote router.
I have succesfully config an IPSec VPN Tunnel by using a Router Scientific Atlanta Cisco 2320 and a RVS4000 4-Port Gigabit Security Router with VPN.On the site of Router Scientific Atlanta Cisco 2320 this is some info: [code] On the site of RVS4000 4-Port Gigabit Security Router with VPN this is some info: [code] Remember that you can not be on the same range of IP, I mean, you can not have 192.168.0.X if the remote network is on 192.168.0.X, you have to change some of the Routers.I show the configuration on Router Scientific Atlanta Cisco 2320: I show the configuration on RVS4000 4-Port Gigabit Security Router with VPN:If all is correctly configured, you should see on Router Scientific Atlanta Cisco 2320 the Status Connected:
If all is correctly configured, you should see on RVS4000 4-Port Gigabit Security Router with VPN the Status Up.As you can see, I'm connected to the remote Router (RVS4000 4-Port Gigabit Security Router with VPN) by my own web browser accesing by the local IP 192.168.0.10.I have used Authentication MD5, maybe is not the best one but I had no time to test SHA1, I will when I will have time.
I am working on IPSec Passthrough on an ASA 5520, with version 8.3, and ASDM 6.3. Currently I have a requirement for users in my internal network (10.10.249.128 / 25) to be able to connect to external IPSec VPN servers.
So I created a network object with 10.10.249.128 / 25, and used dynamic PAT to translate the source ip address to the external internet facing outside interface:
I then added the following rules on the inside-in ACL: However troubleshooting shows that isakmp is passing through the firewall, but esp and ah is not.
For isakmp:
For ESP:Seems like the nat rule is drawing my ESP traffic,
Is there any way to setup an IPSEC tunnel to be able to go from my subnet, 192.168.75.x and be able to reach anything on the other side of the tunnel, 192.168.X.X?
I have a newly aquired asa 5505 that I just set up to the bare minimum configurations. I followed a cisco paper on how to create a "remote access vpn" setup for ipsec. I can sucessfully connect and establish a VPN, but when I try to access an inside resource from the vpn address, the asa blocks it.
We currently have a client that uses the IPSec VPN Client to remote in to their PIX 501. When they connect, it secures communication and immediately connects/minimizes and the tunnel-group name/password is sufficient so no prompt for a username/password from a local/radius database.
When setting this up on a newly purchased ASA, a username/password is prompted every time they try to connect. Is there a way to eliminate this feature or a command in the tunnel-group or group policy so that a username/password is not required after the connection profile establishes the VPN? It is ASA 8.4.
I had IPAD setup IPSEC Remote Access VPN to try to conect to ASA5540 and Cat65 VPN service module(V1).I works fine on Cat65 VPN service module using IPAD client, but it is fail on IPAD client connect to ASA5540.THe message should be "VPN server is no response".My laptop Cisco VPN client(Windows 7) works fine on both (Cat65 VPN module and ASA5540).There is any special setting for IPAD client on ASA5540 ? The IPAD ios version 5.1.1.The ASA5540 version 8.4(4)1 ADSM 6.4(9) The Cat65 version is quit old binding with CatOS V12.2 etc.
how to setup a both ends of an IPSEC VPN tunnel using a software client such as shrewsoft vpn and an 800 series router?
I've tried following the instructions on cisco's site, but I don't really understand which interface I should use? Dialer, VLAN1 or UnNumbered to a Loopback?
I'm OK with most basic features of the router, but never had any luck with VPNs?
We are setting up an old office building as an offsite data center. The network cosists on a PIX 501 firewall and a 2811 router. I am attempting to setup a GRE tunnel over IPsec back to the main office. The main office consists of a PIX515, a 2821 router, and a 2921 router.
There is also an ASA5510 in our main office that is used as our primary connection for all of our external services and as a GRE endpoint for our other offices. The PIX515 is used to connect our main office clients to the internet and we would like traffic between it and our offsite data center to go across it as well. The default route is to use the ASA. We used policy based routing on the 2821 and 2921 routers to direct the appropriate traffic to the PIX515. Right now I am not able to get the tunnel setup. It appears that the offsite datacenter is sending packets but is not receiving any when I issue the “show crypto ipsec sa” commands on both firewalls. I will show the output of that command below.
Main Office The external address 198.40.227.50. The loopback address 10.254.10.6 The tunnel address 10.2.60.1 Offsite Datacenter The external address 198.40.254.178 The loopback address 10.254.60.6 The tunnel address 10.2.60.2

i'm using an rv220W and i whant to know if is it possible to assign vpn traffic to a vlan when i setup an ipsec tunnel?
example: Im using different vlans on my rv220W. Vlan 10: engineers (ex: 192.168.1.0/27) no intervlan routing Vlan20: sales (ex: 10.0.123.0/24) no intervlan routing
This is what i need: - An engineer is on the road and when he makes a ipsec vpn connection => assignd to the vlan "engineers" so he can access the server/pc's in that vlan.and when someone from the sales group starts a vpn connection he needs to be in the vlan "sales" so he can access his pc/data,...
I have a question about VPN Concentrator FTP Backup configuration to get logs on FTP server. I have configure FTP Backup with all details but I still do not see any logs on FTP server. Do you know what could be the issue? I have never used Concentrator and not sure what needs to be done to get in working condition. I am using VPN Concentrator 3015 series.
My organization has an old 3005 that i need to wipe the config of. The problem is that i cant gain access to the device via the console port. Every time i try connecting using a terminal session, all i see is a blinking cursor. As a result, my question to the group is there another way to wipe the config on this device?
Our VPN 3000 concentrator's admin password was changed by somebody so i reset the password by using straight through serial cable, now the problem is it allows me to login with admin through console but not through admin web interface or telnet. I have enabled telnet and http access but still no success. Concentrator is using internal database so no AAA server is configured.
