Cisco VPN :: Configuring L2TP IPSEC VPN On ASA 5505 / Can’t Ping Or Access Resources

May 2, 2011

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.

Cisco Firewall :: L2TP IPsec Doesn't Work On ASA 5510

Dec 21, 2010

I'm trying to setup a L2TP VPN Connection on my ASA 5510 to connect with Android/Windows (Native Clients).I'm using the newest Releases:Cisco Adaptive Security Appliance Software Version 8.3(2) Device Manager Version 6.3(5)
 
My asa config just the interesting part:

If i try to connect with a Windows 7 Client (NOT behind NAT) I get the Error 691.
 
I see that Phase 1/2 are working with debug:

Dec 22 16:51:25 [IKEv1]: Group = DefaultRAGroup, IP = XXXXXX, PHASE 2 COMPLETED (msgid=00000001)
 
Then I see this "Error":

Dec 22 16:51:26 [IKEv1]: Group = DefaultRAGroup, IP = XXXXX, Session is being torn down. Reason: L2TP initiated
  
I don't understand why it doens't work....I tried many templates from the net but nothings works.

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.

RB450G Does L2TP Or IPSEC Use GRE Protocol

Oct 28, 2011

I 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?

Cisco VPN :: 7200 - L2TP Over IPSec With Draytek

I have a Cisco 7200 and need to establish L2TP over IPSEC session with a Draytek Fly200. Draytek must use L2TP over IPSEC to provide LAN-to-LAN connectivity. IPSEC phase 1 and 2 is ok, L2TP tunnel is also established, but on cloned virtual-access IPCP negotiation is not completed:

I think my VPDN configuration from Cisco side is not correct, but I cannot find configuration examples for this kind of solution.

Cisco VPN :: 5510 - L2TP Over IPSEC Static NAT

May 22, 2013

I 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.

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?

Cisco VPN :: Forward L2TP IPsec 5510 Requests To ForeFront TMG Server

Mar 3, 2012

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

Cisco Firewall :: 5505 Anyconnect With IPSEC

Sep 27, 2012

A customer has a 5505. According to the datasheet the limit of IPSEC sessions is 25 and the limit of anyconnect sessions is 25. Does that mean I can have 25 IPSEC tunnels and 25 Anyconnect tunnels at the same time? The customer needs at least 50 concurrent tunnels on his ASA. Am I understanding it correctly?
 
I was thinking the customer could pay for the anyconnect essentials license and connect his anyconnect clients to the ASA. Is that a good option to get the 50 concurrent clients connected?

Cisco Firewall :: Reboot ASA 5505 Every Time Modem Reboots?

May 21, 2013

I currently have a problem where I have to constantly reboot my ASA whenever my cable modem reboots. The ISP (Pen Tele Data) is setup so that my ASA has to obtain its' static IP using dhcp (ip address dhcp setroute) on the outside interface. Now, I also have another location with a cable connection (Comcast) that does NOT experience the same problem. However, the difference is this ISP allows me to assign my static IP directly on my outside interface. What can I do so that I don't have to reboot my first ASA everytime modem reboots.

Cisco VPN :: How To Setup L2TP On ASA 5505

Jun 13, 2011

There is so much mis-information on the Internet and Cisco's own support site has bits and pieces everywhere (I've found at least 5 support pages in Cisco that address this subject), none work or are directly targeted at what I would consider is a major use case for this product. I can see from the many posts everywhere that getting L2TP/IPSEC to work is a major problem, requiring many configuration steps that all have to be perfect and there seems to be some trick to get it to work that most people struggle with. Most of the advice out there is impertinent and highly technical but doesn't work.
 
I would like to know if there is any consolidated instructions that WORK to create a VPN server on the 5505 using the ASDM and also how to set your Windows 7 (or 2008) client to work with it.
 
Like I've said, I've spent hours and hours on this and have yet to get anything to work. I have a brand new 5505 connected directly to DSL (static IP) that I ran the wizard on and followed the best advice I could find (by the way there's TONS of information on getting XP to work but afaik, this does NOT work for windows 7). Now that I've tried various things without success, I believe I've gotten it so fouled up I need to reset to factory defaults and start over.
 
I also have another brand new 5505 connected to a different DSL line.   Behind that firewall, I have both windows 7 clients and windows 2008 server.  I've tried lots of different things to get these to work including the registry hacks (which, if indeed is required, I seriously can't believe that Cisco hasn't given us a tool for).
 
I have tried to use the ASDM to do all my programming as I find the CLI to be extremely error prone and virtually incomprehensible.So, what the world needs is one place that gives all the instructions on what to do, step-by-step that really work for this simple use case of windows connecting to the ASA.

Cisco VPN :: L2TP On ASA 5505 Just Doesn't Work?

Nov 20, 2011

Cisco ASA 5505 ver 8.4. Most things work but now I want to setup a vpn connection..I have done this 2 ways, first by using the "VPN Wizard" in ASDM and then 5 hours later removing everything and configuring from cli. And it just doesn't work, client (WinXP & Win7) gets "error 792" and sometimes "error 789" (both indicating problem with phase 1, I'm pretty sure of that) Googling on those gives a few suggestions none works. All I get in the log on Cisco is the "Error processing payload: Payload ID: 1" Google on that only comes up with a few pages telling me this message is caused by an error. (Yeah, I could never have guessed...) For the cli config, I followed this tutorial carefully (3 times actually...) url...I'm using PSK for IPSec, entered same on Cisco and client - checked several times, this is not a password/PSK issue. Ports opened on Cisco: 500, 1701, 4500 (For a try I opened all ports, no change.) And here's the "show run". [code]

Cisco Firewall :: ASA5505 - Port Forwarding For L2TP

May 25, 2011

I have a Windows 2003 server running a L2TP VPN server on it. I'm putting theASA5505 in replacement of an open source firewall.
 
My question is that, I can't seem to forward the ports correctly for L2TP to the internal address of the 2k3 VPN server. It seems to me that the ASA is trying to negotiate the VPN connection rather than forward it internally.
 
Cisco ASA5505
WAN 216.136.1.2
LAN 10.1.1.1/24
Windows server - 10.1.1.14

Cisco VPN :: 871 / How To Reduce IPSec VPN Connection Establishment Time

Aug 30, 2011

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?
