Co-worker just got a Blackberry Playbook tablet and, try as I might, we cannot get the darn thing to successfully set up a working IPSEC/L2TP vpn tunnel to our ASA 5510, which acts as a multi-purpose VPN concentrator. Any luck setting up L2TP/IPSEC VPN to ASA from Blackberry Playbook?
View 0 RepliesI have a 5510 that i have configured for L2TP over IPSEC, not using AnyConnect. The first, and most prevelant being, VPN clients are unable to ping/access any of the hosts that are assigned a static NAT from the inside interface to the outside interface. I was able to circumvent this by adding another static NAT to the public interface for the incoming clients, but this caused intermittent connectivity issues with inside hosts. The second issue involves DNS. I have configured two DNS servers, both of which reside on the internal network and are in the split_tunnel ACL for VPN clients, but no clients are using this DNS. What is the workaround for using split tunneling AND internal DNS servers, if any?
i've had two different CCNA's look at this numerous times to no avail. A ping from a VPN client to any internal host works fine, unless it is one that is NAT'd. You can see in the config where i added the extra STATIC NAT to try and fix the issue. And this works perfectly across the tunnel but only intermittenly from the internal 10.1.4.x network. [code]
I'm opening a new topic related to my problem with the VPN connection, to avoid confusion, since there are many, in the old information, no longer required.
I would like to configure my ASA5510 L2PT/IpSec to accept connections from Windows clients. I happen to authenticate via AD credentials. When I try to connect is because the error 691. I enabled debugging on the machine the following:

i configurated ipsec vpn at cisco asa 5510. all them are working very well. now i want to change ipsec remote vpn to L2tp over ipsec.i have router, asa and 3750 switch. all nat translation are done at router , ipsec vpn configurate at asa.
this is my ipsec configuration. this is working config. as you see i do static nat asa outside ip for vpn at router. now i want l2tp over ipsec. before i do it i have some question
1. must i do static nat port udp 1701 for l2tp over ipsec vpn? can i write access list at asa to open port 1701?
2. can i remove this static nat or i can not be change anything.is this nat is true for l2tp over ipsec vpn?
3.as you see user authentication from radius server at ipsec vpn. i also want this is same as l2tp over ipsec vpn..
4. i think that i must be add this addtional config. is this true? tunnel-group DefaultRAGroup ppp-attributesno authentication chapauthentication ms-chap-v2
is this config enougth for l2tp over ipsec vpn?? what is addtional config i need?

I have added an ASA 5510 to my network between the Internet and a Windows 2008R2 server running ForeFront TMG. Before the ASA was added, vpn clients using Microsoft Windows 7 vpn client using L2TP/IPsec connected to our vpn. After ASA was added, clients can no longer connect. I would like to know how to configure the ASA to forward the vpn requests to the ForeFront TMG server for authentication and access to internal network resources. Mail is forwarded appropriately through the ASA to internal mail server and Internet access for LAN users works just fine.
Topology:
ASA 5510 (outside interface is ISP IP address, inside interface is 192.168.1.1)................Forefront TMG (outside nic 192.168.1.2, inside nic is LAN gateway IP address).
I have altered the registry key of the client vpn pc's per Microsoft Technet URL
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.

I am trying to get a L2TP/IPSEC VPN going on one of my servers behind the DIR655 router I have used Port Forwarding and Virtual Server and neithere seem to allow these ports to be open in either situation a port scan shows the ports closed..My ISP (Comcast) does not block these ports?
View 14 Replies View RelatedI had my PPTP VPN working great at my old place, now that I moved I also upgraded my speed which means I got a different 2Wire. This 2Wire can only do DMZ mode and can't bridge. ( I tried everything, including the mdc page, no go). This works fine apart from blocking GRE somehow. I'm using a Mikrotik RB450G as my PPTP server. Does L2TP or IPSEC use the GRE protocol?

We have ASA 5520 running 8.2(3) software and we're trying to make Remote Access VPN (l2tp/ipsec) working from Android. We succeeded in making IPSEC tunnel (ending "Phase 2 completed"), but we cannot make L2TP tunnel working.We're using RADIUS for L2TP authentication, but ASA doesn't even try to check credentials entered by use. The same set of credentials entered on Windows {XP, VISTA, 7, Mobile} works ok. Which debugging options should we turned on?

I’m configuring a L2TP IPSEC VPN on a 5505 asa so that windows 7 clients can natively connect. It connects correctly during Phase 1 and 2, but I can’t ping anything or access resources on the internal network. This is my first time working with an ASA.

I would like to allow my remote users to access all resources behind the ASA and my remote branches. Here is my setup. ASA5510 as hub at data-center.
Internal network 172.21.x.x Directly connected

I can access my internal resources connected to the ASA but not the DMZ or branch offices. Do I need routing and reverse route injection?
To establish s secure tunnel using GRE with IPSec do I need to add a SPA-IPSEC module to my 7604 chassis?
View 1 Replies View RelatedWe 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.

I'm currently setting up two VPN 3000 Concentrators at two different sites to create a IPsec LAN-to-LAN Tunnel. I have gone through all the basic configuration guides on the CISCO site, but a LAN-to-LAN session is never created. I have enabled the logs on the Concentrator and it displays no errors at all - it appears the Concentrator is not even trying to establish a IPsec LAN-to-LAN Tunnel.After running through the standard setup provided by CISCO, is there anything I need to do to make the Concentrator try to create a Tunnel, or should this be automatic once all settings are in place?

I need to create a IPSec Site-Site VPN in the Single mode firewall. Is it possible to create the tunnel. I have ASA 5510 Security Plus with Ver 8.3
View 5 Replies View RelatedWe'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 have an ASA 5510 running 8.4(2) which has a site to site IPSec VPN to a 3rd party who run some form of Checkpoint. The VPN establishes and allows access to a server in our DMZ on all ports that we have tested (so far HTTP, SSL, RDP, FTP) except for SQL which doesn't even seem to reach the server. I've got Wireshark running on the DMZ server and if the 3rd party initiates a TCP conversation from their server on any of the working ports to the server I see all of the expected packets arrive with the correct IPs etc (no NAT takes place across the VPN) but when an ODBC client attempts to query the SQL server on our DMZ box the packets do not arrive at the server. What I can see is the RX byte count on the VPN increasing each time the query is run but definitely no SQL arriving at the server.
Also if I revert the ASA back to the old PIX it has replaced with the same VPN config but on version 7.x then it works just fine.
We have an ASA 5510 running 8.3 that we need to use to terminate a LAN to LAN IPSEC VPN.
Problem is we only have one public address available so have had to configure the link between the ASA and the Internet Router on private addresses.
Is it possible to NAT the public address to the inside or outside interface of the ASA and terminate the VPN on that interface?
I have been given the following details by a company for us to connec to their IPsec VPN.

I was going to use VPNC with linux but the company said they do not use remote access. So I tried a draytek vigor 3300v, that as well did not work. Had very bad logging so i couldn't troubleshoot.In the end I have decided to buy the cheapest cisco device that will allow me to connect to this.
I have an ASA 5510 running ver 8.0(2) that has (4) Ipsec tunnels going from it to various other locations. I am having an issue with data transfer speed on only one of the Tunnels. This tunnel is between the 5510 and the 5555, on that link I am getting a dat transfer rate of a little over 120k a second, whereas if I pull the same set of files from another location I am seeing a transfer rate of 5m per second.
I have verified that it is not a capacity issue on the Internet bandwidth on both locations, and I can pull the same data from the same location to various other locations via Ipsec tunnels, I am only having an issue with a specific tunnel going from the 5510 to the 5555.
Since it is not affecting other tunnels on the 5510 nor is it affecting tunnels on the 5555 going to other locations, I am leaning toward a routing issue within the ISP? I will say the ISP is taking me a long way around to stay in the same Metropolitan area.
