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 have a Cisco ASA 5505 Firewall. I am using windows VPN. I have configure IPSEC/L2TP Vpn. And now i hv some problem..
1) VPN is connected but I notices that VPN client connection gets in "HANG" mode after couple of minutes.
2) I am getting error when i try to connect my SQL Server (windows 2008) [code]

The other two do authenticate and they get an IP from the VPN Pool. but they just cant access anything.

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 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?

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

i am now trying to configure a Cisco Small Business Pro SRP 521w router for a branch office, i am trying to get the router to connect to a L2TP VPN server inside my datacenter, but seems to me like L2TP VPN client function is not supported inside the SRP 521w router.
Can Cisco implement L2TP VPN client into the firmware for the SRP 521w router in the future ?
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 a very basic lab site to site vpn setup where I have a ASA 5505 running v7.2(4) on one side and a cisco 2811 on the other side.
What's my issue?
I can't seem to ping from cisco router to the 'inside' network of ASA (see config below) and can't seem to ping from ASA packets leaving the 'inside' interface to cisco router even w/ an ICMP ACL permit outside in. However I'm able to ping within ASA inside network & ping cisco 2811 side w/ packets leaving ASA 'outside' interface just fine.
example:
-------
ciscoasa# ping inside 10.20.20.1 (to cisco loopback1 from ASA inside)
Type escape sequence to abort.

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 see that Phase 1/2 are working with debug:

I don't understand why it doens't work....I tried many templates from the net but nothings works.
Basically we have different customers using the same 5510 firewall. We have created one sub interface for every customer on the inside interface. There are differed NAT rules for every customer all using the same block of public IP addresses on the outside interface. They do not have access to each other’s network so I cannot make any exemption rules between two sub interfaces. The problem is for all our customers that they cannot communicate with each other over Internet, Email, Applications etc. using the external IP address. A work around is to use a proxy server, but they do not agree with that. I cannot make exemption rules between sub interfaces for security reasons.

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 recently bought a new Dell XPS Ultrabook 13 with i7 processor. It worked fine for about three weeks, then all of a sudden it refuses to connect to the internet. I am still connected to my wifi network, but the network and sharing centre shows the connection as dropped between the hub and the internet. Troubleshooter offers no answers. I know other Windows7 users have experienced this and so I have ALREADY done the following:
Tried accessing the internet in safe mode with networking. This works, so it is not a hardware issue. I can definitely access this web in this way.Rebooting my wireless router etc. I know this is not the issue though, as other devices such as my iPhone can still access the web through it (and the XPS, in safe mode)
Possible spy/mal ware. I think this is unlikely. A) the laptop is new b) I am extremely careful on what I download c) I have run repeated full system scans with both my preloaded AV software (McAfee) andMalwarebytes anti-malware. Neither has unearthed anything at all. Not a single item, and they both are checking against the latest databases.
I ran msconfig and deselected all startup programs and services except MS ones. I also downloaded and did similar through ccleaner. No joy.I checked devices through device manager. All devices seem to be working normally. No conflicts. I disabled and enabled the network wifi miniport adaptors. Again, nothing.The most frustrating thing is that I haven’t actually made any system or setting changes recently, so I don’t understand how this could suddenly have just happened. My only suggestion is that I downloaded the usual round of MS updates the other day.
I have Cisco ASA 5505 and i want to create vpn remote access ...l
so i created and connected to the vpn ...my problem is to reach my Local connection of 192.168.1.0 /24 i put the WAN Connection in the FA0/0 and put my LOCAL AREA CONNECITON into FA0/1 .. so how i can route or translate my connection , and using cisco ASDM 6.1 in GUI ,,,
I'm trying to connect two ASA 5505s for a IPSec L2L VPN. They can connect, but not pass traffic from the AnyConnect subnet. I've added the config from ASA-2, with the LAN subnet of 192.168.138.0 and a subnet of 192.168.238.0 for AnyConnect client.
I'm trying to get the AnyConnect Clients access to the 192.168.137.0 LAN behind ASA-1 at 1.1.1.1. Having both 192.168.238.0 and 192.168.138.0 both access 192.168.137.0 is acceptable.
There's probably a lot of cruft in this config, as I've been reading all over forums and docs without much success.

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.
