Cisco VPN :: IPsec VPN Connection With ASA5540
Jul 11, 2011
I meet a strange question about IPSec VPN between '' C3945 A---ASA5540 A----------Internet----------ASA5540 B---C3945 B "
I set ipsec vpn between ASA5540,and set Tunnel between C3945.the C3945 Configuration as follow:
C3945 A C3945 B
interface Tunnel10 interface Tunnel10
ip address 172.18.1.225 255.255.255.252 ip address 172.18.1.226 255.255.255.252
tunnel source 172.17.0.1 tunnel source 172.17.1.121
tunnel destination 172.17.1.121 tunnel destination 172.17.0.1
the strange issue is like that:
On C3945A : I can ping 172.17.1.121 with the source address 172.17.0.1,but can't ping 172.18.1.226
On C3945B : I can ping 172.17.0.1 with the source address 172.17.1.121,but can't ping 172.18.1.225

We have an ASA 5540 successfully using SSL VPN Client Tunnels with no issues, and have been attempting to build the ability for IPSec Clients to connect as well. I have the authentication working, yet cannot complete the establishment of the tunnel for the client. The client receives an error of "Secure VPn Connection terminated by Peer, Reason 433: (Reason not specified by Peer)". In the log on the client, I see the following when the connection drops:
(this is after successful connection, split tunnel setups, then this set of items appears in the log)
377 09:29:08.071 02/28/13 Sev=Info/4 IKE/0x63000014
RECEIVING <<< ISAKMP OAK INFO *(HASH, NOTIFY:STATUS_RESP_LIFETIME) from <outside IP of ASA>
378 09:29:08.071 02/28/13 Sev=Info/5 IKE/0x63000045
RESPONDER-LIFETIME notify has value of 86400 seconds
[code]...
I see the message where it terminates and where is says 'Account Start Failure' but I can't figure out what that is indicating..

I need to set up several L2L ipsec tunnels using ASA 5540 (8.2) as a central node and ASA 5505s (8.4) for branch offices. So far I've configured ipsec for the sake of testing between a 5540 and one of 5505, but it blocks ICMP between hosts behind ASAs. Although there's an echo response from 5540's inside interface (172.30.0.1) to echo requests from a host behind ASA 5505 and I see ipsec counters growing. I still can't figure it out despite hurting my eyes with cisco manuals for the relevant ASA software versions.
One thing I couldn't understand in the 8.4 documentation - it says I need ACLs to allow ipsec traffic on outside if I don't NAT/PAT it. Isn't it achieved with "sysopt connection permit-vpn" or do I have to do it manually? I've actually tried adding access-groups for the "in" traffic on outside and those ACLs get hits on both ASAs.
The packet-tracer shows some weird DROP at phase 6 on 5505, but I see no rule denying this traffic and the description doesn't mention implicit rules. [code]

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.

I'm trying to setup a L2TP over IPSEC vpn connection on a PIX 501 that will use key sharing. In addition, I have a PPTP connection setup which allows connectivity. Two things, the L2TP vpn client I am using does not connect and times out. The second is that the PPTP client I use does connect, but cannot ping any resources on the network.
The config on the PIX is below:

I am trying to configure a Cisco ASA 5505 for Remote Clients.I am using ASDM interface and used the startup and ipsec wizards for my configuration but im hitting a stumbling block.For the last 2 days i have tried a number of configuration changes in attempt to make this work but failed, so i have done a factory reset and gone through the wizards again, so i have a clean configuration. Currently i have a Static Public IP Address 81.137.x.x and i am using a Netgear ADSL router, which is forwarding VPN traffic (UDP 500) to 192.168.171.35 (the wan port on the ASA 5505).The Cisco ASA has a default address of 192.168.1.1 I am using Cisco Client 5.0.06.0160.I have configured the client to use Group Authentication with the same credentials as setup through the wizard and im using Transparent Tunneling IPSec over UDP.I have attached 2 documents running_config.txt - which is shows the current ASA configuration Log-View.txt - showing error messages displayed in the real-time log viewer when i try to connect from the remote client.Im not sure whether i need to do any additional configurations for my setup other than simply run the wizards.

I've got random connection issue when I try to connect to a VPN gateway through an ASA 5510 (IPSEC client ->ASA 5510->VPN Gateway).
When the tunnel is coming up, those two lines appears in the captured traffic on the internal interface :
<private internal IP>.500 > <destination IP>.500: udp 541
<public external IP>.500 > <destination IP>.500: udp 541
When it's not coming up, the port nuimber for the public IP is not 500
(private internal IP).500 > (destination IP).500: udp 541
(public external IP).442 > (destination IP).500: udp 541
I don't understand why sometimes the port for the public external IP is 500 and sometimes not.

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.

crypto isakmp policy 10

I currently have an ASA 5510 setup with Dual homed ISP's and a remote access IPsec VPN setup to terminate at either interface. The first interface is named Outside and the second is simply called Outside-2. When outside the company(such as at home), the VPN client will connect on the Outside-2 interface and work normally. The problem is while testing on our DMZ, the VPN Client will not connect on the Outside-2 interface. It will try that interface fail to connect and then connect to the backup Outside interface. This isn't a huge concern because it still connects, but if we were ever to get rid of one of those connections, it would be nice to reliably test from our DMZ.

I have created an IPSec VPN between our ASA (5510) and a Cisco Router running IOS.Only problem i have is that the VPN goes down if there's no interesting traffic from the router and i can't find anything to initiate the VPN Tunnel from the ASA (so we need to wait 'till someone connects on the other side).
Is there any way to make this connection persistent, just like an ASA-to-ASA tunnel?

We bought a RV220W in order to get a VPN in our Small Business. The RV220W will only be used to let clients connect to it and not a tunnel between another VPN box.We could use QuickVPN, but it won't be working in our case, because in order to use QuickVPN, the router wants to change its IP 10.x.y.1. Because we have multiple servers/services that are using a static IP, it would be quite painful to change the subnet. Therefore, we would like to stay on the same subnet and change it in worst case scenario only. This is why QuickVPN is not an option here.We could use SSL VPN, but most of our clients who will connect to the VPN are using Windows 7 x64. I have tried the Windows 7 x64 fix told in the latest firmware release notes, but I can't get it to work on my computer, which is a Win7 x64. It might still be broken. Many of them are not very tech-savyy, so I can't tell them to use a virtual machine to connect.We want a secure connection, therefore IPSec is better than PPTP. I've been trying to setup IPSec for the past hours but I can't get it working. At first, I wanted to use an SSL certificate, but having no luck with this, I switched to a Pre-shared Key (PSK) in order to get things simpler. Eventually I would like to use an SSL certificate, however I would like to get PSK working first to confirm that the IPSec connection is working.
I have attached with this post, screenshots of the IKE and VPN Policies. I have used the VPN Wizard in order to complete these fields. The local identifier is the WAN DynDNS FQDN. However, as for the remote FQDN, there should be none really, because clients are connecting to it, so the RV220W won't know in advance who's connecting and from where. I have read that when using the Responder type, the remote settings should not matter. Also, the PSK is 25 caracters long.After setting the RV220W up, I have set up a L2TP/IPSec VPN connection on my Windows 7. I have set up the connection to connect to the DynDNS address and set up the PSK in the Advanced settings. After I typed my IPSec username and password to connect (which was created in the IPSec users section), Windows tries to connect and times out :
Error 789 : The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer.
At the same time on the RV220W, this error shows up in the logs :
2012-08-26 23:45:24: [rv220w][IKE] ERROR: Could not find configuration for 24.54.xx.xx[500]
I can't figure out what I am doing wrong. I've read the Administration manual quite a few times and it seems that I have followed everything by the book.I have tried to enable/disable my Windows firewall, but did not get any luck. The RV220W is located at a remote office, to make sure that I can connect from the outside, before you think that I'm trying to connect to the outside, from the inside I have changed few settings in the IKE policy to try to make it work. Settings such as the Exchange Mode, because I've read that the Aggressive mode had issues. At this moment, the settings are back to default, once the wizard has been run. I'm thinking about setting a PPTP to confirm that this works, then move up to IPSec PSK, then to IPSec SSL Certificate.

Just bought myself an ASA5505 to replace a PIX 501, and having transferred over most of the previous config I've managed to get the two IPSEC VPN tunnels working as before.
Unfortunately when I try and SSH to the ASA the connection just resets instantly even when the tunnel is up. It seems as if the ASA is actively refusing the connection, though the log doesn't state this. I had always presumed that traffic over an established IPSEC tunnel was implicitly trusted and not subject to usual access-list rules.
I am unable to SSH to the ASA from the 10.0.0.x range, but I can SSH to a machine on 10.27.0.4 (so I know the tunnel is up and working)
Config (minus irrelevant sensitive information) is attached for reference.
Also - though I'm not sure how relevant it is given the tunnels appear to work - when I enter the line "crypto map meepnet-map interface outside" in config mode the ASA reports "WARNING: The crypto map entry is incomplete!" even though I have supplied the access-list, peer and transform-set variables.

I have a 5510 and a 5505 that I'm attempting to configure a simple VPN tunnel over. I have tried step by step configurations form CISCO ASA configs, as well as every source I can find. I have walked throught the config with IOS commands as well as Wizards. All my packets are dropped at the the inside or outside interface.
When I show SH ISAKMP command all I get are 0's straight down.

I am trying to set up remote access vpn on an asa 5520 running 8.4.1. I have the ipsec group, policies, and ip pool set up. When I try and connect with the cisco vpn client I see the following in the logs. Deny icmp src outside:214.67.39.42 dst outside:24.252.51.73 (type 3, code 3) by access-group "acl_inbound". Do I need to put in some firewall rules to allow this traffice so that the VPN can connect?

I set up an IPSec VPN with NAT-T between two cisco router 871. In particular one router acts as a SERVER and the other one as a CLIENT. All the traffic coming from the hosts connected to the CLIENT-router is sent over the VPN (no split tunnel). Everything works perfectly. The only problem is the amount of time the VPN takes to establish the first connection between the two routers. In particular it takes about two minutes. tell me if this amount of time can be reduced (with a partcular configuration instruction)? Or this is the minimum amount of time required for the first connection establishment?

This is for an ASA 5505. I am trying to configure an AnyConnect and IPSec VPN connection and I think it's almost there but not quite yet. When I login from an outside network it gives me the following error for the SSL AnyConnect "The VPN client was unable to setup IP filtering" and "Secure VPN connection terminated by peer" for the IPSec. I previously had this working since Oct, but I was trying to modify it a little to accept LT2P for native Android VPN clients and that messed up everything that I had working perfectly. I checked everything as best as I could to try and match the previous settings but still can't get the darn thing to work. I am trying to also do Hairpinning, I want all VPN traffic to pass through this router... remote LAN and Internet traffic for times when I am at unfamiliar wifi hotspots and need to check email securely. I have included my running config. I also need to configure the ASA to accept native Android VPN connections. I read the most popular thread that worked for a few users but while doing those modifications that is where everything went downhill. T

We have a main and branch office, each with an RVL200 . I configured both with static IP's as provided by my ISP, yet when I try to do a test connection on the IPSec screen I just get that it's "waiting for a connection" in the cell third from the left. Both RVL200 's are connected directly to the modem/bridge supplied by both ISP's.

We are using a CISCO1921-SEC Router. On the "WAN" side we have 1 public IP Adress assigned by DHCP. At the moment we are using the WAN Interface with a crypto-map as endpoint of some IPSec connections. We set up a zone-based-firewall with "WAN" and "LAN" zone. In this setup all IPSec Endpoints are on one Interface - connections to the "LAN" zone can be managed by rulesets. What about connections between IPSec connections and the zone "self".We like to terminate each IPSec connection in a separated zone. How can this be configured ?Each one on a "tunnel inetface" with "tunnel source ..." binding ?

I used to have a Netgear Prosafe 318 conncted to a Netgear Prosafe 336G in a small office environment across the WAN between two offices, IPsec preshared key. The 318 took a dive so I decided to upgrade to a new Cisco RV180 VPN router. I set up the VPN access rules exactly the same and forklift upgraded the Prosafe 318 (same IP, same rules, same pre-shared key, IKE setup etc) and the VPN tunnel comes up fine. However, even though the VPN tunnel says connected and I have no problems pinging anything across IPsec between subnets I cannot seem to connect to anything from the cisco side.
From the Netgear side I can connect to anything on the cisco subnet (192.168.0.1 / 255.255.255.0) but from the cisco side anything I try and connect to on the netgear side (172.16.0.1 / 255.255.255.128) times out.Encryption AES-128 (although also tried 3des), Sha-1 SA-lifetime is 3600 seconds, PFS key group enabled DH-group2 (although also tried group1)IKE policy direction Both, identifier FQDN (both sides), Preshared key SA-lifetime 28800 seconds. Firmware is updated on both the netgear and the RV180 to latest version (1.0.0.30 on RV180).Like I said from Netgear to Cisco through VPN tunnel everything works fine from Cisco to Netgear everything times out.

I have a Linksys E2500 Firmware Version: 1.0.03 and am using the "IPSec Passthrough" for work. On a typical day I'll sign in to my work's VPN, do my work, sign off in the evening, and read my personal email with a direct connection to the internet.
Then on the next morning, I am unable to connect to work until I go to http://192.168.1.1/index.asp and click "reboot." And as soon as the modem finishes rebooting, my laptop can connect to work. I've tried this several days in a row now, and indeed all I need to do to get the VPN passthrough working is rebooting the modem.
Nothing under "Applications & Gaming" is set. I've seen some posts about having a trigger on UDP port 500, but I'm not quite sure how to translate it for the E2500. Plus I'd rather the router "just work" day after day for VPN and everything else, like my old router did! Is there some other setting to try or clearer directions for a bulletproof IPSec passthrough on that unit?

I have an ASA5540 running 8.4(3) which has CA and identity certificates from godaddy.com installed, identifying the ASA to VPN remote users (the are using the anyconnect client.) There is also a separate certificate server located on the inside LAN that is used for internal purposes. All client workstations have identity certs from this internal server.
We would like to be able to continue using the existing godaddy CA/identity certs to identify the ASA to the clients, but we'd like to use the internal CA server to identify the clients when they initiate the AnyConnect session to the ASA.
I have seen other postings that state you cannot have more than one vert on an interface, but this is a little different - only one cert needs to be used to identify the ASA. The other one is only to identify the users. The ASA did allow me to import the internal CA cert.

I had a working vpn configuration between a local and a remote router; the remote router is not under my administration.Now I moved the vpn termination from my side to an ASA5540 software version 8.0(3). The tunnel is up but there is no reachability. The "show crypto ipsec sa" on the ASA shows encapsulated packets but NO decapsulated packets! Routing and no_nat are properly configured.

I have an ASA- 5585X (v.8.2.4) directly connected to an upstream 6509, which is running EIGRP. I configured the ASA for EIGRP with same AS# and network numbers and no auto-summary. Here are the log messages I got:

I lost my SSH connection to the upstream 6509 and couldn't get it back. Luckily I didn't lose my ASDM connection to the ASA, so I disabled EIGRP and went to look at the logs on the 6509.
What causes a K-value mismatch, and how to I rectify the situation?
