But don't work. I also tried to add the pptp and gre in the outside access rules but nothing...
I don't understand why if a connect directly to the outside interface with the same outside network works well.
ej: the pc have 89.120.145.14 ip and the outside asa have 89.120.145.140 and if I create one vpn in this pc the outside ip 89.120.145.140 with the correct parameters the asa don't discart 1723 and connect ok but if this ip is not of this range discards 1723...

Mavericks VPN dropouts with native VPN client and Cisco IPSec
Since update to Maverics I am experiencing VPN dropouts with native VPN client and Cisco IPSec
I am connecting via a WIFI router to a remote VPN server
The conenction is good for a while but eventually it drops out.
I had Zero issues in mountain lion and only have issues since the update to 10.9
I had similar issues in teh past with an unrelaibel wifi router but i am using a Verizon Fios router and it has worked impecably until mavericks
My thoughts are:
1 -issue with mavericks ( maybe the app sleep funciton affecting eithe VPN or WIFI daemons)
2- Issue with cisco router compaitibility or timing with Cisco IPSEC
3- Issue with WIFI itself on mavericks - some sort of WIFI software bug

ASA 5505 Site to Site IPSec VPN WILL NOT CONNECT
I've spent 2 days already trying to get 2 ASA 5505's to connect using an IPSec vpn tunnel. I cannot seem to figure out what im doing wrong, im using 192.168.97.0 and 192.168.100.0 as my internal networks that i'm trying to connect over a directly connected link on the outside interfaces with 50.1.1.1 and 50.1.1.2 as the addresses (all /24). I also tried with and currently without NAT enabled. Here are the configs for both ASA's, the vpn config was done by the ASDM, however i have also tried the command line apporach with no success. I have followed various guides to the letter online, starting from an empty config and from factory default. I have also tried the 8.4 IOS.

Cisco ASA 5505 - Keeps dropping internet connection
Hi,
We are having some issues with our Cisco ASA 5505 unit, it intermittently drops the outside interface connection. Internally the network appears to be working correctly with no issues. Even though the outside interface indicates it is 'up' access to the internet is lost from our LAN. This seems to be ocourring more and more often! This is happening for all users on the network too. Reloading the ASA seems to correct the problem temporally but this isn't really an option during peak periods in the day as this would obviously hinder work being carried out by employees.
Any ideas?
Any help would be greatly appreciated!!
Thanks,
John

What happens when you assign eth0 as internal interface and eth1 as outside if?
Also configure logging (/debugging) to see if there are hardware issues or something else.
And it seems you have a range of public addresses. What happens when you connect a device, e.g. a laptop directly on the internet access device and send continue ping to an internet host.
When you loose internet connectivity, is the laptop still pinging to that host?
Hopefully this helps you,
Kind regards,

Cisco ASA 5505 Remote Access IP/Sec VPN Connectivity Issues
We have a Cisco ASA that we use just for Remote Access VPN. It uses UDP and was working fine for about 2 months. Recently clients have had intermittent issues when connecting from home. The following message is display by the Cisco VPN Client :
"Secure VPN connection terminated locally by the Client. Reason 412: The remote peer is no longer responding"
Upon looking at a client side packet capture, I notice that no response is being given back to the client for the udp packets sent to the ASA on udp 500. If I login to the ASA from the LAN and send a single ping FROM the ASA, then the client can connect without issue. I don't understand the significance of the needed outbound ping since ping is not used by the client to test if the ASA is alive.
Once again this is a remote access udp ip/sec VPN. I set most of it up with the VPN wizard and then backed up the config. The issue started happening at least a month after setup (maybe two) and I restored to the saved config just in-case, but the issue remains.
Any insight would be greatly appreciated.
I'm using IOS 831 and have tried 821 and 823 as one thread that I found recommended downgraded to 821.
Thanks much,
JustinJavier,
I logged into the ASA last time the VPN went down. I issued the following commands:
debug crypto isakmp 190
debug crypto ipsec 190
capture outside-cap interface outside match udp any any
I then used a remote access tool to access the client and tried to connect. I got absolutely nothing from debugging. So I issued the following command:
show capture outside | include 500
and also got nothing. So I issued the following command:
ping 4.2.2.2
Upon which my normal deug messaged began to showup, so I issued the show capture outside command again and recieved the expected output below:

It would seem as if no traffic reached the ASA until some outbound traffic to an arbitrary public IP. In this case I sent an echo request to a public DNS server. It seems almost like a state-table issue although I don't know how ICMP ties in.
Once again, any insight would be greatly appreciated.
Thanks,

Cisco ASA 5505 site to site IPSec VPN with RV220W issue
I have a ASA5505 connected to RV220W through IPSec VPN. When using SMB to transfer large file, the ASA5505 will show error message:
CTM ERROR: Invalid input parameters, ctm_get_scb_prot_stats:1561
The error message from the debug crypto engine. When the message show, the speed of the transfer will slow down quickly, and even no data can be go through between ASA and the RV220W. But the IPSec SA and the IKE SA is active, and can ping the inside network in both site.
Both ASA5505 and the RV220W has been updated the latest firmware. I have surf the Google but no such related issue found.
Any suggestions on where to look would be much appreciated.
Thanks in advance
TerryHi Ted thanks for your reply and information.
The strange things happened in RV220W shows the IPSec sa is expired, but the ASA5505 IPSec and IKEv1 sa is active. Inside both site internal network can ping to other side, but cant transfer file through Windows SMB. It seems when I transfer over 4GBytes of file, it will start happening and required clear IPSec and IKEv1 sa so that the VPN tunnel will start up again.
I am already surrander for this issue...... -
ASA 5505 switch from Mode: access Port to Trunk on the fly via CSM ?
Hi
Can I configure the Port at the ASA 5050 from Mode: access Port to trunk during the FW is running in a production area without console access ?
As I know at the 5505 ist should work
sincerley
AlfredAre you using the same access port to access the ASA via CSM? If you are, then i would strongly recommend console access.
If you are using a different port to make the changes, then yes you can configure it. However, I would still recommend configuring it during non production hour, just in case there is an issue. -
Internet connexion problem for remote site in Site to site VPN asa 5505
Hi all
I'm configuring a site to site Ipsec VPN in 2 sites using ASA 5505 V 8.2, The VPN is working fine i can ping machine in the 2 sides but the problem is the remote site dont' have internet.
The architecture is, we 2 site Site1 is the main site and Site2 is secondary site there will be Site3, ...
The internet connection is based in Site1 and site2 and site 3 will have internet connection through Site1. Site1, Site2 and Site 3 is interconnected by Ipsec VPN.
Here is my ASA 5505 Configuration :

Can anybody help why my remote site can't connect to Internet.
REgards,
RaitsarevoHi Carv,
Thanks for your reply. i have done finally
i used no crypto ipsec nat-transparency udp-encapsulation in my end router only.
and in remote access VPN i have enabled UDP for client configuration. the most imprtant is i have given IP add of same LAN pool to VPN user,

ASA 5505 VPN with dhcp at endpoint
I have a new customer that I installed an ASA 5505 to replace a Linksys VPN router. They have a main office with a static IP address, 3 branch offices with static IP addresses and 2 branches that are doing DHCP from the ISP for their router address. I have no problem getting the static VPNs up and running. My problem is with the VPN connections that are doing DHCP. I can go in and determine what IP they are currently using and setup a connection and it works fine. The problem is of course when their IP address from the ISP changes, which seems to happen at least daily. What is the proper way to setup a connection that is using DHCP? Also, can you setup multiple connections this way? Currently the 2 locations have different passwords setup in their routers.
I need help ASAP as this customer is getting frustrated quickly. I do not want to lose a customer that I just got over this.
Thanks in advance,
SteveGo to this link and scroll down to Site to Site VPN (L2L) with IOS and Site to Site VPN (L2L) with ASA, you can use the links example depicting your scenario requirements, where one end is dynamic and other static for Ipsec L2L IOS-to-ASA or ASA-to-IOS.
The best solution obiosly is having static IP addressing, make that clear with your client , but these exmaples are very good solution for your problem.
Keep in mind that the DHCP dynamic side will always be the initiator to bring up the tunnel , not the static side.

Cisco ASA 5505 VPN Routing/Networking Question
I have a very basic question about Cisco ASA 5505 IPsec Site to Site VPNs. I want to install a Cisco ASA 5505 at a Data Center, in a LAN subnet that utilizes publicly routable IP addresses. I would like to install a second Cisco ASA 5505 in a remote branch office as its peer.
Regardless of whether I use publicly routable IPs at the branch office in the "inside" network or non-routable IPs, how would the devices and servers at the Data Center know to route IP packets destined for the branch office back through the Cisco ASA instead of through the default gateway at the Data Center? I can see accomplishing this if every single device at the Data Center is configured with routing table entries, but that isn't feasible. It also isn't feasible to use the Cisco ASA 5505 as the default gateway for all of the devices as the Data Center, allowing it to decide where the traffic should go.
What am I missing? Is the solution to try to map branch office IPs to IP addresses within the Data Center's LAN subnet so that all of the traffic is on the same subnet?You can do it in several different ways.
One way is to tell the server that if it has traffic to network x then it needs to go to the ASA all other traffic is to head for the default gateway.
In windows this is done via the route command
do not forget to make it "persistent" otherwise the route will disapear when your reboot the server.
in unix/linux
It is also the route command
Or you can tell your "default gateway" to route that network to the ASA
Good luck

ASA 5505 - 2 Internet Connections, Problems with the Default Route
Hey there,
i have a Problem at a Customer Site at the moment. The customer uses an ASA 5505 with two internet connections attached to it. On the first connection (which is the only one in use at the moment) he has some Static-PAT's from Outside to Inside where he translates different services to the internal servers. He also has a site-2-site VPN terminating there and AnyConnect.
He now wants to switch the Internet Traffic from Inside to the new Internet Connection. Therefore changing the default route to that new ISPs Gateway. The problem now is, that no traffic recieved on the old "outside" Interface is transmitted back out of that old "outside" Interface. And this happens although the "same-security permit intra-interface" command is set.
Can you tell me what's wrong here? For every Static-PAT from outside to inside there is also a dynamic PAT from inside to outside. But the ASA seems to ignore this. I have not looked into the Logs yet, was too busy finding the problem because i had no real time window to test on the productive ASA.
Can it be achieved in any way? Having a default route on the ASA which leads any traffic to the second internet connection while still having connections on the first internet connection where no explicit route can be set? Because connections arrive from random IPs?
Many thanks for your help in advance!
SteffenPhillip, indeed , I have as well read may comments,it all depends on your environment as they all differ from one another, you best bet is to have a good solid plan for upgrade and fall back. You do have a justification to upgrade for features needed, so I would suggest the following:
1- Do a search again in forum for ASA code upgrades and look at comments from users that have gone through this process and note their impact in fuctionality if any. I believe this is good resource to collect information .
2- Very important , look into release notes for a particular version. For example version 8.0, look into open CAVEATS usually at the end of the link page, reading the open bugs gives you clues what has not yet been resolved for that particular code and if in fact could impact you in your environment, it is possible that a particular bug does not realy apply to your environment becuase you have yet not implemented that particualr configuration. Usually we all try to aim towards a GD (General Deployment) code which is what we all understand is most stable but not necesarily means you have to be stack in that code waiting for another GD release, in my personal experience I have upgraded our firewall from 7.2 to 8.0(3) long ago and had no issues, and recently upgraded to 8.0(4)when it was first release in August this year.
Release notes
http://www.cisco.com/en/US/products/ps6120/prod_release_notes_list.html
3- AS a good practice precaution -
a-Backup firewall configs in clear text as well as via tftp code.
b-Backup running code and ASDM version code currently running in firewall.
c- Save the output of " show version " to have as reference for all the feature licenses you currently have running as asll as activation keys - good info to have to compare with after upgrade.
d- Ensure that the code you will be using to upgrade also uses correct ASDM version code.
I think with thorough assesment and preparation you can indeed minimize impact.

Best practices for securing communication to internet based SCCM clients ?
What type of SSL certs does the community think should be used to secure traffic from internet based SCCM clients ? should 3rd party SSL certs be used ? When doing an inventory for example of the clients configuration in order to run reports
later how the data be protected during transit ?From a technical perspective, it doesn't matter where the certs come from as there is no difference whatsoever. A cert is a cert is a cert. The certs are *not* what provide the protection, they simply enable the use of SSL to protect the data in transit
and also provide an authentication mechanism.
From a logistics and cost perspective though, there is a huge difference. You may not be aware, but *every* client in IBCM requires its own unique client authentication certificate. This will get very expensive very quickly and is a recurring cost because
certs expire (most commercial cert vendors rarely offer certs valid for more than 3 years). Also, deploying certs from a 3rd party is not a trivial endeavor -- you more less run into chicken and egg issues here. With an internal Microsoft PKI, if designed
properly, there is zero recurring cost and deployment to internal systems is trivial. There is still certainly some cost and overhead involved, but it is dwarfed by that that comes with using with a third party CA for IBCM certs.

ASA 5505 site-to-site VPN tunnel and client VPN sessions
Hello all
I have several years of general networking experience, but I have not yet had to set up an ASA from the ground up, so please bear with me.
I have a client who needs to establish a VPN tunnel from his satellite office (Site A) to his corporate office (Site Z). His satellite office will have a single PC sitting behind the ASA. In addition, he needs to be able to VPN from his home (Site H) to Site A to access his PC.
The first question I have is about the ASA 5505 and the various licensing options. I want to ensure that an ASA5505-BUN-K9 will be able to establish the site-to-site tunnel as well as allow him to use either the IPsec or SSL VPN client to connect from Site H to Site A. Would someone please confirm or deny that for me?
Secondly, I would like to verify that no special routing or configuration would need to take place in order to allow traffic not destined for Site Z (i.e., general web browsing or other traffic to any resource that is not part of the Site Z network) to go out his outside interface without specifically traversing the VPN tunnel (split tunneling?)
Finally, if the client were to establish a VPN session from Site H to Site A, would that allow for him to connect directly into resources at Site Z without any special firewall security rules? Since the VPN session would come in on the outside interface, and the tunnel back to Site Z goes out on the same interface, would this constitute a split horizon scenario that would call for a more complex config, or will the ASA handle that automatically without issue?
I don't yet have the equipment in-hand, so I can't provide any sample configs for you to look over, but I will certainly do so once I've got it.
Thanks in advance for any assistance provided!First question:
Yes, 5505 will be able to establish site-to-site tunnel, and he can use IPSec vpn client, and SSL VPN (it comes with 2 default SSL VPN license).
Second question:
Yes, you are right. No special routing is required. All you need to configure is site-to-site VPN between Site A and Site Z LAN, and the internet traffic will be routed via Site A internet. Assuming you have all the NAT statement configured for that.
Last question:
This needs to be configured, it wouldn't automatically allow access to Site Z when he VPNs in to Site A.
Here is what needs to be configured:
1) Split tunnel ACL for VPN Client should include both Site Z and Site A LAN subnets.
2) On site A configures: same-security-traffic permit intra-interface
3) Crypto ACL for the site-to-site tunnel between Site Z and Site A needs to include the VPN Client pool subnet as follows:
On Site Z:
access-list permit ip
On Site A:
access-list permit ip
4) NAT exemption on site Z needs to include vpn client pool subnet as well.
Hope that helps.

ASA 5505 as hw vpn client to PIX501 or ASA5505 w network extension mode
Hi!
We have been using a PIX 501 for a couple of years now to access a
local network with Cisco VPN software client. However we now need
access from another site with multiple users so I decided to buy two
ASA 5505 UL bundle to do the job. First i tried to just hook up the
new ASA at the remote site and connect to the PIX 501 with easy vpn.
In went fine. I configured the new ASA right from the box with the old
vpn profile settings and it worked right away. But as we also need the
remote site to be accessed from the main site (PIX side) i tried to
enable "network extension mode" but then the tunnel didnt work
anymore. it connects but no traffic is coming through. I set it back
to normal mode (only client) and it worked again.
Is there anything else I need to do to be able to use network
extension mode than just enabling it in ASDM ?
The samt thing happens when using two ASA 5505 the same way.
Software versions are:
PIX: 6.3
ASA 5505: 7.2.1 (used to be 7.2.2 but I had to downgrade because of a bug in 7.2.2 - vpnclient fails after reboot)
I also did try the latest 8.2 with very little success. Seemed a bit buggy.
Thanks,
BjornHi!
Thought I could add some info. Our Head unit is 192.168.1.1 and the connecting ASA 5505 is 192.168.10.1. When I try to ping a machine (192.168.1.201) from the remote site I get this in the ASA log:
With network extension mode
302020 192.168.1.201 192.168.10.2 Built ICMP connection for faddr 192.168.1.201/0 gaddr 192.168.10.2/512 laddr 192.168.10.2/512
With only client mode
302020 192.168.1.201 192.168.10.2 Built ICMP connection for faddr 192.168.1.201/0 gaddr 192.168.1.9/1 laddr 192.168.10.2/512
It seemes to me (quite the newbie here on ASA) that the unit does not handle the gateway address correctly when using network extension mode. The PC i use to ping from is 192.168.10.2.
Any ideas from the experts ?

B
