ASA easy VPN connection problem
Hi guys,.
I configured easy VPN between 5510 and 5505. Every thing seems fine, however, if there is no traffic in the tunnel in the next few hours, I can not initial 5510 5505 (customer) traffic. But if I first traffice 5505, there is no problem.
Anyone know why?
Thank you
Hello
This is normal behavior, it is part of the easy vpn functionality. The 5505 will act as a remote for the 5510 vpn client. This isn't like a site to site vpn or both ends know the IP address of the remote peer, and so that each peer can initiate the connection, here the 5510 don't know on the network and 5505 IP when it will connect via the easy VPN.
If you want the tunnel to be put in place at both ends, I would say that you are using a classic site-to-site connection as described here:
http://www.Cisco.com/en/us/docs/security/ASA/asa80/Getting_started/ASA5505/quick/guide/SITESITE.html
I hope this helps.
Kind regards

ASA 5505 ASDM VPN connection problem
Hello
We are running a version of firewall ASA 5505 8.4 (4) 1. The ASDM version is 6.4 (9).
The problem is when the creation of remote access VPN connection, it works fine for about 2-3 days.
After that, the VPN client cannot connect more and gives the error code 789.
In this case, the VPN clients are clients of Windows 7 from different remote networks with the same problem scenario.
Windows 8.1 clients cannot connect at all and show the same error code...
All connections go through the keys defaultragroup and preshare match on both sides.
When the user to connect attemps I receive the following text in the log of the ASDM:
6 April 10, 2015 10:52:39 group = DefaultL2LGroup, IP = 5.240.31.116, P1 retransmit msg sent to the WSF MM5 April 10, 2015 10:52:39 group = DefaultL2LGroup, IP = 5.240.31.116, in double Phase 1 detected package. Retransmit the last packet.5 April 10, 2015 10:53:03 IP = 5.240.31.116, encrypted packet received with any HIS correspondent, dropWhen I implemented the remote login through ASDM I followed the instructions according to the following link:The steps were a little different, but almost the same, given that these instructions show an old versionI'm interested in trying the steps according to this link but not sure this will help me solve the problem id:Any help would be appreciated!Thank youHello

Easy VPN configuration problems
Hello
I have 6.2 (2) Version PIX PIX 515E. I am trying to setup the easy VPN server to this topic. This pix not recognized the next line of the comand.

is there a command line I can use inplace of them. I have also attached my config so I would be very grateful if someone could check and advice me what to do to raise this connection.
Thank you
Take a look at this:
Yes nat - t is available on 6.3.x and above and no it is not enabled by default on the PIX / ASA. It is IOS.
Please note if useful, cordially

Hi all
First of all, I apologize if this is something that I can google. My knowledge of the administration of the network is all self-taught, so if there is a guide that I missed please point me in the right direction, it is often difficult to Google the terms for troubleshooting when your jargon is not the height.
The main problem is that when ping devices internal when you are connected to the results are very inconsistent.
Ping 192.168.15.102 with 32 bytes of data:
Reply from 192.168.15.102: bytes = 32 time = 112ms TTL = 128
Request timed out.
Request timed out.
Request timed out.
We have implemented an IPSec VPN connection to a remote Cisco ASA 5505. There is no connection problems, connection seems constant, etc. good packages. At this stage, I can only assume I have configuration problems, but I was watching this while if long and pair with my inexperience configuration of these settings I have no idea where to start. My first impressions are that LAN devices I'm ping do not send their response back or the ASA does not know how to route packets back?
Here is a dump of the configuration:
Output of the command: "show config".

Hi Graham,
My first question is do you have a site to site VPN and VPN remote access client.
After checking your configuration, I see you don't have any Site to SIte VPN configuration, so I'm assuming you ara facing issue with the VPN client.
And if I understand you are able to connect VPN client, but you not able to access internal resources properly.
I recommend tey and make the following changes.
First remove the following configuration:
NAT (inside) 0 inside_nat0_outbound_1 list of outdoor access
NAT (inside) 1 192.168.15.192 255.255.255.192
You don't need the 1st one and I do not understand the reason for the second
Second, one is your pool IP subnet (192.168.15.200 - 192.168.15.250) and I don't know why you added this NAT.
If possible change your subnet pool all together because we do not recommend to use th ip POOL that is similar to your local network.
Try the changes described above and let me know in case if you have any problem.
Thank you

SDM &; easy VPN server problem
I'm having a problem setting up an easy VPN server using Cisco Security
Device Manager Version 2. 0a on a router in 1711 with IOS 12.3 (7) XR3.
I have reset the router to the factory defects since the opening screen of SDM.
Connect to 10.10.10.1
User: cisco
Password: Cisco
Start SDM for the initial router configuration dialog box.
Don't use CNS
On basic configuration screen:
Hostname set to router

Advanced options screen
Selected for VLAN1 port address translation
After reading the summary, I chose the FINISH. Asked if dialog box I have
you want to set up a basic firewall, I selected YES. I left all the
secure by default items selected. I clicked FINISH. SDM detected that the
DHCP client on the untrusted external interface and asked if I wanted to
allow DHCP traffic through the firewall. I selected YES. The configuration
has been delivered.
Save the running-config startup-config and reloaded the router.
Released and renewed my ip address and then reconnected in 1711 from new
user name and password. SDM restarted.
Has begun the task of configuration and choose to set up an easy VPN server.
The opening screen had a command prompt to enable AAA. I launched the selected task
After that the AAA commands have been delivered to the router.
I chose the interface FastEthernet0 menu drop-down

Add the user name: User1

Selected new address Pool: 10.1.1.80 to 10.1.1.90
Test after you have configured the selected button.
Exit this screen, there was a warning SDM on the NAT with ACL rules
have to be converted into NAT rules with course maps. I clicked YES to let
SDM convert rules.
Tests successful Easy VPN Server and client screen displays a warning
on the "crypto ipsec df - bit clear' needing to be defined." He was not a
way to put it in SDM and the search function had no success.
I copied the running-config to the startup-config and tested the router from a
connect remotely using a different ISP.
The results:
The SDM monitor shows the client connection, but the client cannot ping
any host on the LAN of the router. No one on the LAN can easy ping of VPN client
Assigned IP of VPN, but they can ping the client using the asigned IP ISP
address.
It seems that SDM not correctly configures the 1711 to route of the
VPN interface to the local network.
I enclose my 1711 Running Configuration generated by SDM.
Hello
I think that the reason why the ping is not successful is that your LAN IP address (connected to the VLAN interface) and the pool of IP addresses assigned to the client are in the same network.
You can try assigning a pool of IP addresses for VPn clients that is in another subnet (say 10.1.2.80 to 10.1.2.90) and then try to ping?
You can change the pool by means of configure-> additional tasks-> local swimming pools.
You can then disconnect the client on the Monitoring page and connect again.
Kind regards

VPN connection problem: keep connection
I'm having a problem with the maintenance of VPN connection. I connect okay but the line VPN disconnects after about 2 minutes each time. I use XP Professional V2002, Service Pack 3. I have disabled the WIndows firewall, as I have F-Secure software suite with its active firewall. I connect laptop wireless via a Belkin router. I had no problem for months up until August when suddenly this problem appeared. I have disabled firewall F-secure, but that did not help. I also disabled the firewall on the router, but again without success. Can you please help?

I have a Cisco 881 router and try to connect to a customer (customer VPN Cisco 5.xxx) to this router.
Here is a diagram of my network:
LAN (192.168.252.0/24)--- router Cisco 881 - router N ° 2 - Internet - router N ° 3 - Client (192.168.1.10))
Router Cisco 881:
-@IP lan: 192.168.252.1
-@IP wan: 192.168.0.2
-Gateway: 192.168.0.1
-DNS: 192.168.0.1
Router N ° 2:
-@IP lan: 192.168.0.1
-@IP wan: xx.xx.xx.xx
-Port forwarding: 500UDP to 192.168.0.2
-Port forwarding: 4500UDP to 192.168.0.2
I have create this VPN profile:
-IP address of the virtual Tunnel Interface: FastEthernet4
-Configuration mode: REACT
-Address pool (the VPN client): 192.168.254.10-> 192.168.254.149
-Split tunneling: 192.168.252.0/24
-Authentication: local
-No firewall (for testing only)
When I connect my VPN client for the first time, everything is OK: VPN connection is Ok, and I can ping any computer on the local network (192.168.252.0/24)
If I disconnect/reconnect, the connection works, but I can't access all the resources on the local network.
Once again, the computers on the lan ping, I have:
-reboot the Cisco router
-enable/disable RIP (in the dynamic routing of the CCP section): strange isn't it?
But who works for the connection of a customer: if I disconnect/reconnect the client once again, I cannot ping all resources on the local network.
I'm getting crazy!
I used a sniffer tool on a machine on my LAN, and I see ICMP trap (ICMP request).
If ping may come from VPN of LAN, but not for VPN LAN.
Any help would be appreciated.
Thank you
Nicolas
Yes, you forgot to apply the plan crypto on the external interface.

Hope that solves the problem.

Thank you!!
Can you try to add this:

ASA 5510 IPSEC VPN connection problem
Hello
We have an ASA 5510 (ASA version 8.0) of remote access VPN configured and works most of the time, but there is a problem when you have more than one client that connects to the same office remotely. When the first VPN client is connected to the remote desktop, everything works fine, but when the second client connects to the VPN, it connects fine but do not get any traffice return to customer. I can see under monitor-> statistical VPN-> Sessions-> remote access-> Rx Bytes is 0. Both connections are from the same public IP address of the remote desktop. I changed some settings on NAT - T and a few other things, but without success.
Could someone help me please how to fix this?
Thank you very much.
Make sure that customers use because that probably her you're not. (default value is NAT - T).

Ikev1 ASA 5505 VPN connection error
Hello
I had previously defined our VPN using IPsec on our ASA 5505 via the ASDM. It was workign fine until an outtage power loses my settings on the device. (possibly a recording of order is not pressed)
Now when I try and put in place, once again I am recieveing an error to port binding. I have configured as normal using the wizard and activate split defintion and exempt the network inside.
The isssue when you apply the settings that I get is:
"[ERROR] crypto ikev 1 activate outdoors.
IkevReceiverInit, cannot bind the port. "
When I try to connect to the VPN I then get an error "the server cannot be reached" or something similar to that...
Could someone please shed some light on what can cause this problem?
Best regards, the Paris
William.
Hello
Thanks for the information!
We will need to know why this host using UDP 4500 and if this host really needs to use this port.
What type of application is running on this host?
What is a host internal or external?
You may also block the host on the SAA on the incoming interface to avoid the use of the UDP 4500 port using a group of access (outside or inside). Don't forget that you will need a ip to allow a at the end of the ACL to avoid any problems. Another option would be to use IKEv1/IPsec over TCP
IKEv1/IPsec over TCP allows a Cisco VPN client operate in an environment in which IKEv1 or standard ESP may not work or may work only with the change of the existing firewall rules. IPsec over TCP encapsulates IPsec protocols both IKEv1 in a TCP packet as and allows a tunnel secure two firewalls and NAT and PAT devices. This feature is disabled by default.
The default port is 10000.
HostName (config) # ikev1 crypto ipsec-over-tcp
You also need to activate on the VPN client under the profile.
Change > Transport > IPSec over TCP.
I hope this helps.

Hello
We have a server to remote client, on which we need to connect via VPN. My VPN is able to connect. But any application that needs to connect via VPN does not work. I also can't ping on remote servers. While for others its works very well. I can't understand the problem, I tried to reinstall the VPN client.
I am using windows XP pro and the client VPN CISCO 4.0.3.
Hello
Your Windows XP question is more complex than what is generally answered in the Microsoft Answers forums. It is better suited for the IT Pro TechNet public. Please post your question in the forum TechNet for assistance:

Client VPN connectivity problems
I use the cisco VPN client to connect to our network, located behind a 515E. The client is authenticated and gets an ip address but cannot ping or connect with one of the hosts. The connection is to a network of customers that is also behind a 515E. I have successfully connected using the same policy to other places and have had no problem. What confuses me, is that we have used to have a Netscreen firewall before and he had a netscreen vpn client which connected since their network with a problem. Is that something they need for their firewall so that we can get through the traffic?
Try to turn on NAT - T on your pix, by setting up:
ISAKMP nat-traversal 20
and configure the client vpn accordingly:

IPSec VPN connectivity problem
OK, I have the following Setup. An asa 5540 is the vpn server and some cisco vpn site-to-site 2811 routers allows you to connect to it. All cisco routers have the same ip address in their internal interface, so I'm nat'ing to another ip to connect to the vpn. It goes the same for servers behind. So we have
IP nat inside source static 10.0.10.10 10.1.89.10
IP nat inside source static 10.0.10.30 10.1.89.30
OU.10 is the et.30 router server. Vpn comes up, and I cannot pint from my internal network server say Server 10.0.20.10 leash. Server 10.0.20.10 I can ping both the ip nat' ed. However, I can't ping routers 10.0.20.10. Also, I try ping 10.1.89.10 on the router and it pings fine. The other 10.1.89.30 ping does not when 10.0.10.30 does. Help, please. I need the router to communicate with 10.0.20.10 break.
Thanks in advance.
Since you're natting, and you use the same LAN ip subnet in routers (very bad desgin) try using an extended ping of the address on the lan interface nat pool.
