We have a corporate site with a Cisco ASA 5580 (8.1), a remote office with a Cisco ASA 5510 (8.2) with a L2L VPN to corporate. A vendor has a L2L VPN to the corporate ASA with access to the remote office across the VPNs (hairpinning). The corporate office accesses an application at the vendor on port 23. Everything is working with regards to the vendor accessing resources to the remote office and the corporate office accessing the application at the vendor. Our goal now is to restrict the vendor to port 23 from the corporate network and port 9100 to the remote office. On the corporate ASA I setup a VPN filter and applied to the vendor's L2L vpn but when I apply the filter (see below) all traffic stops to the vendor such as telnet.
I have been searching for days trying to find out what could be wrong with the configuration of an ASA5505 running Firmware version 7.2(2). I am trying to set up a hairpin connection between my laptop on the VPN tunnel (192.168.25.12) to access the server across the L2L VPN (192.168.1.10) on the diagram below.
The remote VPN function is working, as I can RDP to the 192.168.25.10 server from my laptop, and the L2L VPN is working since I can RDP from server 192.168.25.10 to server 192.168.1.10. I am trying specifically to run RDP from my laptop without having to log into the .25 network.
I have tried multiple changes to my NAT tables and my ACL configurations to no avail.[code]
I have a network behind an 861 and users are unable to access e-mail from the local exchange server from their iPads using the 802.11wireless network. The wilrelss network is working fine and the iPad users connect fine.I was told that that i need to configure "hairpin DNS".
I have several machines behind this firewall. Each machine has it's own outside static IP and i've setup a NAT for each machine to their outside IP.Everything is working great, EXCEPT, from behind the firewall, I can't browse my own websites that I am hosting from behind the firewall. From a command prompt, the machines can resolve the url to the correct outside IP of our web server. Our DNS is externally hosted. I just can't get a website to open from behind the firewall. IE won't connect.
I did some logging, and I see from the firewall logs, the inside machine trying to hit the external ip. The log shows an INTERNAL IP on a random port trying to hit the external IP of our webserver on port 80. It says success! If I use packet tracer entering the same ips and ports, it also says success. And yet the site won't load on the inside machine?
The client machine I am testing from behind the firewall does also have it's own natted external ip. I'm not a command line/scripts guy. Looking at my ASDM Device Setup Interface GUI pagae, I see at the bottom both boxes are checked, one for enable traffic between different interfaces at the same security level, and the other enable traffic between hosts on same interface. My outside interface is security 0, my internal network interface security is 100.
Need configuring Client to Site IP Sec VPN with Hairpin on Cisco ASA5510 - 8.2(1).
The following is the Layout:
There are two Leased Lines for Internet access - 1.1.1.1 & 2.2.2.2, the latter being the Standard Default route, the former one is for backup.
I have been able to configure Client to Site IP Sec VPN 1) With access from Outside to only the Internal Network (172.16.0.0/24) behind the asa 2) With Split tunnel with simultaneous assess to internal LAN and Outside Internet.
But I have not been able to make traditional Hairpin model work in this scenario.
Following is the Running-Cong with Normal Client to Site IP Sec VPN configured with No internal Access:
LIMITATION: Can't Boot into any other ios image for some unavoidable reason, must use 8.2(1)
running-conf --- Working normal Client to Site VPN without internet access/split tunnel: ASA Version 8.2(1) ! hostname ciscoasa [ code ].......
Neither Adding dynamic NAT for 192.168.150.0/24 on outside interface works, nor does the sysopt connection permit-vpn works
What needs to be done here, to hairpin all the traffic to internet coming from VPN Clients. That is I need clients connected via VPN tunnel, when connected to internet, should have their IP's Nattered against the internet2-outside interface address 2.2.2.2, as it happens for the Campus Clients (172.16.0.0/16).
Is It possible to hairpin clientless SSLVPN connections (ASA5510)? I'd like to create a portal that allows a user to log into the central clientless webpage and access RDP/VNC resources at remote sites connected via site-to-site VPN. Initial testing shows the user can access resources at the hub site, but not the spokes. I have the standard:
I am putting an pre-labbed DMVPN Hub config onto a production 1841. We had to upgrade the IOS to support protection with NAT so the current IOS we're running is c1841-adventerprisek9-mz.124-25g.bin.I can paste the configuration in fine (via the tunnel interfaces) and the router accepts it however the 'show dmvpn', 'debug dmvpn' and other related commands don't work. I have checked the IOS feature navigator and it definitely shows that DMVPN phase 1 and 2 are supported in this image.
Actually I have to make a VPN between an 5520 ASA and a Cisco 887VA-K9 Router. Connected to ASA I have the outside interface, the inside-DMZ interface, the PCs interface and the VoIP interface. In the other site I will need to have a new subnet and a VoIP phone which I need to connect to the VoIP subnet in the other side in order to work with our CCM servers.I need two VPN established between ASA and 887 Router?
I have a pair of 5505s with an IPsec VPN between them. On the first 5505, I also have a user connecting to it via client based vpn. The user cannot access systems on the other side of the ipsec tunnel. That 5505 protects subnet a.b.c.d, the user is on subnet a.b.e.d which is not inclusive to a.b.c.d. First, am I correct in the assumption that I need to add the vpn network of a.b.e.d to the list of protected networks, and second if I change the list, does it drop and reset the ipsec vpn?
How much the CPU is impacted by SSL VPNs on Cisco ASA 5500's?I believe that the ASA offloads a lot of its encryption/decryption on a built in VPN accelerator rather than placing load on the main CPU. Is this correct?
According to the ASA 5520 specs - it can handle a throughput of up to 225Mbps of VPN traffic. Of course, it does not say whether this is SSL or IPSEC but I would like to understand what impact say 100Mbps of SSL VPN traffic would have on the main CPU.
We need this information to gauge whether an existing firewall has enough capacity to cope with existing load plus additional new SSL VPNs.
I've got a setup where we have a wireless connection coming in and using mikrotik router. We have multiple stores coming in via the wireless with a dmvpn.
The vpn's terminate on the cisco c870 and can be seen when running: show dmvpn.The cisco has a default route to the fibre router (10.0.0.252). The wireless router is the default gateway for the network. The failover from wireless to adsl fails. (due to the cisco routing traffic back to the wireless router when wireless fails)
If I change the default route on the cisco to dialer1, the failover works, but none of the vpn's connect. The Branches all have dynamic ip addresses. The HO has a static ip.
My goal: I want to achieve adsl failover for when the wireless goes down and still have the vpn's connected.
Can I have some sort of "Dynamic" route on the cisco. So when the vpn traffic comes in via wireless and hits the cisco, the vpn traffic can then go back out that way via the wireless router, but still have a default gateway on the dialer interface for failover?
I have been endlessly searching around online, and trying things on the firewall, and cant seem to find an answer to this problem. Its probably something really simple right under my nose! I am using an ASA 5510, which currently has a few seperate site-to-site VPN connections configured, which connect to other Cisco devices on clients networks.
I work from home, so also connect to our network using Remote Access VPN (any connect) to connect to the network at the data centre.
Just to be clear, here is my amazingly drawn network diagram:
[[my house]]-------------- <any connect VPN>------------[[ASA 5510 / Data centre]]-----------<site-to-site>-----------------[[Client network]]
The problem I am having, is that I cannot connect directly from my house to the client network, I need to RDP into some server in the data center, then from there I can see the Clients network. Is there routing to be setup somewhere? between VPN's? Ive looked into the routing options on the firewall and cant seem to find anything that works. I've searched for this and cant find answers, even some sources saying its impossible.
I have a Cisco 877 ADSL router which won't let me play with my VPNs like I used to in pre-Cisco days.I have a VPN server which resides on the inside of the network which used to get it's L2TP as well as PPTP tunnels passed straight through the ADSL router. No problems there with the old router.Now I opened the relevant ports for both TCP and UDP on the 877, but VPN simply won't establish when trying to connect from the outside. Process of getting the 877 to stop wanting to take charge of things VPN and just pass them off to an inside server?
I need to VPN into my work from my laptop on the private side of the 877. This works fine until after authentication, then the VPN connection goes silent, no traffic going through. Works fine when for instance using my iphone hotspot to connect through from my laptop. It's only not working when the 877 is in the equation.
So I have a server running Linux and am looking to add VPN functionality to my home network. I have OpenSSH running and it works great for tunneling and remote file transfers but doesn't quite get the job done.I would like to be able to map a network drive in Windows to my Linux box and understand a VPN could accomplish this, problem is I really don't know anything about Virtual Private Networking! I was hoping someone could explain to me the differences between SSH / VPNs and point me in the right direction towards configuring OpenVPN on my Linux box.
I've been reading this site for a while, and finally decided to post I'm really interested to see what everyones opinion on this is.My company currently uses what i would call traditional site to site VPN's using crypto maps, main site has a pair of ASA's in HA and remote sites use ISR's like 1801's.I've recently been playing in my lab with GRE tunnels using IPSec protection (note this is config from my labs, so ip's and key's are just randomly selected)
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 am setting up a simple remote IPsec VPN with a ASA 8.4. All I want to do is the remote user can VPN into the ASA, from there, he can browse the outside Web pages in the internet. and we'd like not to use split-tunneling. The outside infterface is 192.168.1.155/24, which is inside our network and this subnet works fine to outside. The pool for vpn is 192.168.0.0./24 (please pay attention to the 3r octet)
I configured and the remote user can vpn in and get an IP from the pool. but it seems that he cannot do anything. he cannot ping anything.I suspected the NATTing that i use. What is configured wrong? What traffic need to be natted and what need not.

I want to split my traffic between two ISP's. I want all traffic to pass over one connection EXCEPT my VPN tunnels, which I want to use the second ISP. How should I set up (protocol binding?) to accomplish this? (I have run into various problems trying to load balance all traffic. So I am trying to "partition" traffic.)
The current setup we have contains two seperate networks, each managed by their own Cisco RV042 (10/100 4-Port VPN Router), and each have their own connection to a Comcast Business Class SMC Modem. (Each has its own static WAN IP provided by Comcast). Both VPN routers have VPN access configured allowing us to connect to our company's corporate intranet and network, and vice versa. Just as a reference point, We will call the first VPN 'GamesNetwork' and the other one 'AdminNetwork'. A problem came up where the computers on AdminNetwork could not access the resources of the GamesNetwork. The problem was resolved by our at-the-time official corporate IT guy but the solution was never explained to me. Recently i got curious and went into the config pages and found that each VPN router was linked to the other the same way corporate links to our VPN's, whch is by using the Internet IP of that vpn... So to me this says we are linking two local vpn networks using their internet connection which is on the same modem.. to me this seems messed up. is this really the way it needs to be done? Now... I have thought of the idea 'make the two networks into 1..' and it could work. but.. i dont have the permission to make this happen.
if you have two vpn routers side by side in the same room, is there a more local means of giving 1 vpn access to the resources of the other and vice versa?
I use a cisco asa 5520 to terminate multiple site to site VPNs. Due to the configuration of a parteners network, i have had to install 2 routers into this parteners network, i have been supplied static private IP addresses for each router each router has a unidue LAN subnet which is the VPN's protected network.The partener use's PAT with only one public facing IP address.The VPNs are initiated from the parteners network using an IP sla ping.
Upon installing my first VPN router in the partenrs network, once NAT-T was enabled on the local ASA the VPN started working fine. After installing the second VPN router i tried installing the new config on to the ASA but via CSM, the ASA complains that it can not have 2 VPN's with the same peer address configured.
I would like to create two site-to-site VPNs, one for data and one for VoIP, between the same sites. One end is an ASA 5510 and the other is a third party firewall. Is this possible if I use different sets of IP addresses for each tunnel?
I have to connect through VPN for work so that I can RDP into my remote development machine, but their internet speed is painfully slow. Is there any way I can route my general internet browsing traffic through my local connection, while still maintaining the VPN connection to my remote box?
accessing my cisco ASA, last night we were doing VA on our ASA, after that iam not able to access it through ssh nor telnet. its not giving me any error.. i tried from different system also. SSH & telnet allowed from inside to 0.0.0.0 i have re-generated rsa keys when it was working. ASA version is 8.2 now when i connect telent is giving me blank prompt. i can login using ASDM.
Our ASA is a 5580 version 8.1(2) and is the L2L VPN peer for a handful of remote offices including a L2L VPN with a vendor who will provide a service for these remote offices. I have two questions/issues:We will need to provide this vendor access to the remote office network(s) only on port 9100 (printing to specific printers at these offices). I know there is an issue with L2L VPNs ability to see each other but if there is a global command allowing all to see each other that would be bad as we have others and don’t want all to see each other.The remote offices are using CIDR 172.20.0.0/16 so each one is assigned for example 172.20.3 the next office is 172.20.4 and so on. For the crypto map access list for this vendor can we use 172.20.0.0/16 or do we need to specify each individual network?
I have recently installed four Cisco RV042 v3 VPN routers for a customer of ours to replace existing Nortel Contivity 1010 devices which were providing VPN tunnels from the customer's 3 branches to their headoffice. The original Nortel devices were working perfectly but the customer wanted some firewall rule changes and the Nortels were proving to be somewhat inflexible and incomprehensible in their configuration hence why they were replaced.
When installing the Cisco routers I configured the VPN settings to match the Nortel device settings so that I could swap out a branch at a time without taking the whole setup down for a day.The customer has a Unix based dumb-terminal application running on a server at headoffice that they access from their branches using terminal emulators on Windows PCs and thin client hardware devices that support vt100 terminal emulation.
Prior to installing the Cisco RV042's everything was working fine. Now they are using the RV042's they keep getting the sessions from their branches dropped. Both PC users and thin client users are losing sessions and it happens with active and idle sessions. I have checked the logs on the routers when users are disconnected and there is nothing logged at that time (other than my login)... I had thought maybe it was to do with tunnel renegotioations so I have set to phase 1 / phase 2 SA timeouts to 86400 & 28800 seconds respectively but this has had no effect. I had also seen somebody advised disabling 'SPI' in the firewall... I have tried this and it makes no difference.
We have an ADSM (version 5.2(3) ) . In ASA ( version 7.2(3)) we are working with routing, access restriction and configuring IPSEC vpn with integration to our AD. We need to get two diferent profiles: one for networking administrators, who are going to manage routing, acls and have the root for ASA, and the other profile is going to be for the vpn administrators. As I read from the ASDM 6.0 user guide is posible define command privilege level. So do you consider posible to define a particular level for all the command related with ipsec vpn (Create, Modify and Delete) and asociate that particular level with the user for vpn administration.
We're trying to get a new ASA 5505 put in place on our network after the untimely demise of our 1841 router. One of the functions of the router that we need to get back up and running is a pair of VPNs to employees that we have working from offsite. These are site-to-site VPNs.
They worked with the 1841 in place, so I know that the other end works. I'm just having trouble configuring the ASA to match. I've been through the wizard in ASDM a couple of times, but have yet to have any luck getting it to connect.
Attached are config files for the 1841 (with both VPNs) and the 5505 (with only 1 VPN in place). What I may be missing in order to get this working?
One note - I am having some trouble with my NAT configurations (another post pending), but I think they are close enough that I hope it's not interfering with the VPNs.
If I can get one running, the other has a nearly identical set up, so I should be able to get the second pretty easily.
In the Firewall Dashboard of my ASA 5580, I get data on every pane, except for the Top 10 Sources and Top 10 Destinations. Why is that, and what do I need to do to get data there?
I got a problem with a cisco asa 5580 like two days ago and the device stop working (there was a mainteinance window and after that the device didn't work). Now we receive the RMA and we are trying to configure the failover so the new device get the configuration form the one that is working.
But this is the message that I gettin:
Failover message decryption failure. Please make sure both units have the same failover shared key and crypto license or system is not out of memory
We already changed the shared key and crypto license but the failover is still down, what are the features that the cisco need to activate to enable the failover?
