VPN IPSec does not work
I am trying to set up a VPN between a 2901 router and 831, but I'm not having any success. When I run crypto isakmp sa, I get this:
cisco831 #sh crypto isakmp his
IPv4 Crypto ISAKMP Security Association
status of DST CBC State conn-id slot
IPv6 Crypto ISAKMP Security Association
It doesn't seem to be a sign of life. I can access internet ok on both routers, but the failure of attempts to ping between the routers LAN IP. I guess it's a problem of nat or access-list, but I don't know what I'm missing at this time. Here are my configs:

A few things that need to be changed:
CISCO 2901:
(1) ACL 100 applies to GigabitEthernet0/1.1, however, I do not see 100 ACL configured on the configuration.
(2) ACL 101 is applied to GigabitEthernet0/1.2, however, I do not see that ACL 101 exists in the configuration.
(3) NAT ACL must exempt traffic between 2 local networks as follows:
NAT extended IP access list
1 refuse ip 192.168.1.0 0.0.0.255 172.20.0.0 0.0.0.255
CISCO 831:
(1) ACL 100 is currently applied to the configuration section 2: NAT and Ethernet0. I would create a new ACL for instruction of NAT that should be added to the deny ACL (NAT exemption) as follows:
access-list 150 deny ip 172.20.0.0 0.0.0.255 192.168.1.0 0.0.0.255
access-list 150 permit ip 172.20.0.0 0.0.0.255 any
overload of IP nat inside source list 150 interface Ethernet1
no nat ip inside the source list 100 interface Ethernet1 overload
Hope that helps.

The conflict will be terminated and should be avoided. It might work if you disable split-mining and road, all via the VPN client...
Ideally business networks should not use 192.168.0.0/24; 1 or 2 either since they are common in home routers... you can also have them change their home network easily

Client VPN suddenly does not work
An external interface address changed on this PIX 501 yesterday - all of a sudden their client VPN does not work. I checked that nothing in the config VPN configuration has changed. I now see a *(HASH.) ("OAK NOTIFY ISAKMP INFO: NO_PROPOSAL_CHOSEN") in the journal on the VPN client.
I crossed referenced on google - nothing in the statements of NAT, Access-list, or VPN configurations have changed. Any ideas?
Thank you
GregYour configuration is absolutely perfect.
Please, try the following:
no interface card VPN crypto outdoors
card crypto VPN outside interface
Remove and reapply the cryptomap on the external interface and see if that helps.
Thank you

'Connected' but 5.0.07.0440 VPN client does not work
Hello
IMPORTANT THING I FORGOT: the customer seems to be connected. It shows a lock locked and says connected but ping shows that nothing is not working too.
I recently tried, in vain, to connect my win7 64 bit laptop to my place of work with the Client VPN 5.0.07.0440. All technitians and support staff could not understand the problem that prevented successful login. Later, I could connect my laptop using the VPN Client 5.0.07.0410 - same home network via an old k9, winXP.
What could be the problem with Win7 system? Work on my old laptop is a temporary solution, but not a good thing. I would be grateful for all the help I can get.
I tried:
-For each access to the Cisco VPN client on my ZoneAlarm firewall.
-Turning off the firewall completely.
-Connect to a different network (in an Internet Café).
Personal support at work said this isn't the network (they checked my too just in case wifi router settings) from my old computer obviously connects without any problem on the first try.
ANY ideas would be very appreciated!
Here is the info yet:
-Cisco VPN Client 5.0.07.0440
-64-bit Windows 7 Home Premium SP 1.
My security software (which may cause the problem as far as I know, even if I close ZoneAlarm):
-Free firewall zone alarm
-Microsoft Security Essentials.
(maybe windows firewall too, if it automatically restarts when I turned off zone alarm)
IMPORTANT THING I FORGOT: the customer seems to be connected. It shows a lock locked and says connected but ping shows that nothing is not working too.
Hello
VPN client traffic is not transmitted from your computer to the VPN at all tunnel.
It's if you have even tried the connection to the remote server before you took this screenshot?
ID say it is a problem with your computer. Some software cause problems for the VPN Client or Client VPN software has problems with the network card real or something similar.
One thing I might suggest is uninstall the firewall software and the VPN Client. After that, it is enough to install the VPN Client and try to login and check the statistics of same as in the pictures above.
-Jouni
EDIT: Whoa 300 posts already
Edit2: If you have a full VPN tunnel, your computer must usually generate connections to the VPN tunnel even if you do not manually connect what either. What makes it even more strange that there are absolutely no traffic in the tunnel. Full VPN tunnel means that all traffic from your computer is transferred to the VPN tunnel when his assets.

Why IPsec does NOT WORK when the PPP encapsulation is running?
Hello
I'm really new in the CISCO world, sorry if I ask stupid questions, I'm still in school to have one day my CCNA?
By reading some books and browsing the net, I was finally able to connect my to routers with IPsec VPN link.
The installation program is to follow:
NETWORK 192.168.1.0/24--->INT ROUTER F0/0 2610XM 172.16.1.1--> INT INTS0/0 S0/0 172.16.1.2 ROUTER 2610XM INT F0 / 0---> 10.0.1.0/24 NETWORK
I can now PING:
192.168.1.1
172.16.1.1
172.16.1.2
10.0.1.1
Sins, I deleted this:
encapsulation ppp
Chap PPP authentication protocol
No idea what I forgot when I implemented this?
Here below the full configuration of work if you remove the lines above (maybe this can be useful for beginners like me):

Remote access vpn Wizard does not work?
I have a brand new ASA 5505 running version 8.2 (5). Am connected with the ASDM and run the installation wizard and the VPN remote access Wizard. I am not able to ping the external interface of the internet, and my VPN client gets no response when you try to connect. Config is attached. Any suggestions?
Hello
1.), you need the default route for the SAA to be able to send traffic to the VPN connection initiator
2.) I guess that is something done by hand when to create the basic configuration of the firewall, OR maybe the Startup Wizard would handle this when you make the ASA initially basic settings.

VPN L2TP does not / / Android 4.4.3
My vpn connection does not work.
The installer is: L2TP/IPSec with PSK in my network private.
Given that my old phone (Xperia S), located on android 4.3.X, still works
I see no problem of configuration, but I guess that it is a problem with android 4.4.XThe same problem occurs on my sony tablet z since the update to 4.4.X
Is there any fix from sony?
I read on a google fix, that should be in place on the 4.4.4, version but updated for 4.4.4 on the
Tablet does not solve this problem.We got a test account of another user with this issue and have found the cause of this. It will be fixed in a future software update.

I am trying to create a VPN connection, but it does not work
The wizard cannot establish a connection. And if I try to record simply does not connect
It does not work. If I try to click on find the problem, there simply
do nothing.
I tried it on another pc, where it worked. So the problem is not the
router or data network. And the curious thing is that I installed it before, but only from one day to the other, the VPN connection was missing.It does not create even a the connection icon
Thank youTry a system restore to a Date before the problem began:
Restore point:
http://www.howtogeek.com/HOWTO/Windows-Vista/using-Windows-Vista-system-restore/
Do Safe Mode system restore, if it is impossible to do in Normal Mode.
Try typing F8 at startup and in the list of Boot selections, select Mode safe using ARROW top to go there > and then press ENTER.
Try a restore of the system once, to choose a Restore Point prior to your problem...
Click Start > programs > Accessories > system tools > system restore > choose another time > next > etc.

After the upgrade yesterday from Vista to Windows 7, now my Cisco VPN does not work and I get an error message titled: grounds 440 driver fault. Any ideas to fix this?
This was the solution! The works of vpn as $ 1 million now. I followed the instructions above to enter the uninstall program and selecting the repair option. I rebooted the machine, then used the troubleshooting on vpn software compatibility option. Selected Windows windows xp (service pack 2) as the correct software and cisco vpn client started right up.
Thanks, Nick!

Check sensor SFR with FireSight via VPN - does not work
Hello security experts.
I have an ASA5515-X with SFR installed 5.4.0 and manage with 5.4 FireSight installed on the virtual machine on LAN and I record the sensor without any problem but when I try to register the sensor to FireSight via VPN I can't do. The interface on the ASA management has no intellectual property nor nameif configured and the interface is connected to the switch, SFR has the IP even configured as LAN addressing. I can see traffic being exchanged between the sensor and the FireSight but I can't save the sensor.
Has anyone managed to register the sensor via VPN? Is there something else to be configured in order to save the sensor with the MC via the VPN?
The delay between the Firesight and the sensor (on WAN and VPN) I get between 80 and 100 ms, what could be the problem?
Thank you very much!
Remi
Hello
If you are unable to telnet from DC to the sensor on the port 8305 delivers connectivity then.
Can try you to ping from sensor to DC:
ping -M do -c 20 -s 1572
By default, the MTU is 1500 on eth0, if the ping does not work I will suggest to lower the MTU on the interface and see if it works. See also: / var/log/messages | grep sftunnel and see the error messages on DC and sensor and send it to me everywhere. Best regards, Aastha Bhardwaj rate if this is useful! -
Cisco Anyconnect VPN does not work in windows 7 64 bit
Hello
I found that the cisco anyconnect (version 3, any series) does not work in windows 7 (64-bit).
The vpn is connected, but there is not any internet access.I tried to solve the problems of:
-Disabling the firewall.
-disable the anti-virus etc.
But while I tried using with 32 bit, it works very well.
Also, I found that there is not a specific version of anyconnect vpn for only 64-bit.
Do any body have the idea how to solve this problem, either it's a bug of cisco vpn itself?
Certainly, you just need to install a later version of AnyConnect. You need a Cisco, for example a SmartNet maintenance contract, to download the new versions.

excludespecified does not work
Hello world
I worked with a VPN for remote access, where everything must be sent through the tunnel via VPN, but specific to a public IP traffic. I tried to use the "excludedspcified" statement in group policy, but it does not work. When the VPN Client must be connected to the ASA and I check the details of router-> secure routes I can only see 0.0.0.0/0. But when I use the statament of "tunnelespecified" it works as it should and Secure routers are registered correctly.
My configuration is:
standard permits the TUNNEL of SPLITTING host 72.XX access list. XX. XX
!
internal TEST group strategy
TEST group policy attributes
Protocol-tunnel-VPN IPSec
Split-tunnel-policy excludespecified
Split-tunnel-network-list value of SPLIT TUNNEL
!
type tunnel-group TEST remote access
General attributes of tunnel-group TEST
address admin-pool pool
Group-RADIUS authentication server
Group Policy - by default-TEST
IPSec-attributes of tunnel-group TEST

I find a Bug or something, but I found nothing. These are versions of software:
ASA: 8.2 (1) 11
ASDM: 6.2 (1)
VPN client: 5.0.07.0410
Thanks in advance,
Jose
Hello Jose,.
In your VPN client, you selected the checkbox "allow LAN access?
Can you please test with this option turned on and let us know the results?
Do not look only secure roads, after you activate that option try to send real traffic to the public IP address.

ASDM does not work in the external interface
Hello
I'm new to ASA. I have ASA 5510 and strives to enable ASDM access through the external interface. but is not working for me... not. I set up a public ip address on the external interface and activated the ssh and asdm. SSH works but asdm does not work. This is a test environment, so I have not yet set up an ACL.
