Cisco ezvpn clinet
Hi all
I have configured the cisco asa 5520 as cisco ezvpn server and cisco 891 as ezvpn client.
the configurtion works fine.i uses client mode on the client side of ezvpn.
but my question is, is it possible to connect to the internal ip address of the ezvpn client side Server ezvpn?
is it possible to do?
and one more thing what is the advantage of the mode of extension of network on the client and how it will work and what are the possible changes that do the client side and the server.
Thank you
Cyril
Here's what you need to change:
No - nat allowed 10.10.10.0 255.255.255.0 10.10.11.0 255.255.255.0
No - nat allowed 192.168.10.0 255.255.255.0 10.10.11.0 255.255.255.0
With the split tunnel, it depends on where you need to access on the client side. If you need to access the client of 10.10.10.200 side, for example, you need to add that in ACL split tunnel. OR if you need to access the entire/24 subnet client side, then you add in the tunnel of ACL split, otherwise, customer return to server traffic goes directly to the internet instead of back to the tunnel.

Cisco ezvpn ASAs cannot ping each other inside interfaces
I have a set ezvpn in place with a 5506 (position B) client-side and a 5520 (location A) server-side. I have successfully connected vpn, and traffic flows. My problem is that I can't SSH in the location b. investigate this more than I can not ping is within the interface of the ASA opposing, or the machines inside each ASA ASA.
I found the following links that describes a scenario similar to mine, but nothing on one of them helped me.

https://supportforums.Cisco.com/discussion/11755586/Cisco-ASA-VPN-established-cant-pingI joined sanitized versions of these two configs. Any help is appreciated.
Hi Adam
The site of B I'm not able to see "management of access to inside. Please try to set up the same. He could solve the problem.
Also on the instruction of the ASA takes place nat can you please try to add keywords 'search non-proxy-arp route'.
something like:
nat (inside,outside) source static (Location A)_Networks (Location A)_Networks destination static (location B)-remote_network (location B)-remote_network no-proxy-arp route-lookup
as I have noted problems with inside access to interface via the VPN when those keywords are not applied. If I remember correctly 8.6.x ASA version had a bug regarding the same. Cordially Véronique -
All-round Vpn connection with EZVpn
Hello team,
Is it possible to configure cisco EZVpn client to start and login before logon on Windows server? Automatically reconnect if the connection has been interrupted?
The IPSec VPN client is a feature called start before logon that will allow you to establish the IPSec tunnel before Windows domain authentication. The function of self-initiation of VPN client can help with your second requirement.

remote router configuration with EzVPN NEM by VPN
I have the following scenario: Some 836 routers Cisco EzVPN network are connected to a hub VPN 3005 in the main façade.
The work of LAN-to-LAN connection and I can also telnet via the VPN from a PC to the main façade of a router to a remote site using the address LAN IP of the remote router as a destination. But does not work for example do a "copy run tftp" on the remote router to the LAN of the main façade.
My questions now are:
Is it possible to transfer the remote routers configuration file or via the VPN IOS image between the remote router and the LAN at the main façade?
And, if possible, how do we?
Thanks in advance
Mark
When you make a "copy run tftp" from the remote router, it goes to the source of its external interface TFTP packets, not its interior. The external interface to your local network packets are NOT included in the list of packages to be encrypted, and therefore they lose.
You must specify the router to the source its TFTP packets from the interface IP address inside, then these will be correctly encrypted and sent through the tunnel.
The following command should do the trick for you:
IP tftp source-interface

Change your pool outside 192.168.2.0/24.
IP local pool vpnpool 192.168.x.60 - 192.168.x.63
Then add an acl of exemption nat for this network.
access-list sheep permit ip 192.168.2.0 255.255.255.0 255.255.255.0 192.168.x.0
NAT (inside) 0 access-list sheep
Then, also change your acl of tunnel from split to reflect the new pool

The debug version, it seems that there is no communication on UDP/500 possible between devices. Maybe something is blocking who?

Thats is correct! You must configure the network extension mode if you want to change the IP address
Here is the guide to configure the router and ASA in network extension mode. Hope you find it useful.
Thank you

Cisco 861 ezVPN license remote problem
I bought a new Cisco 861 SRI with safety advanced on this subject.
When I look in the Dashboad license in Cisco Configuration professional it tells me I have advsecurity licenses with deployment status 'Deployed' function and the State 'active, in use '.
But when I want to configure any type of VPN I get the following error message:
License of technology (advsecurity) associated with this feature is not deployed on this router. Use the link below to deploy the technology license.
When I click the link I find myself in the dashboard to license again.
I Don t have another file license and advanced security features should be sufficient for VPN. At least that's what
http://www.Cisco.com/en/us/prod/collateral/routers/ps380/data_sheet_c78_461543.html said.
What should I do to be able to configure the VPN?
Thankx a lot for any help
Dirk
What version of CCP do you use? I see a few other customer cases with this error and it looks like there may be a problem with CCP 2.5. Customers who use 2.3 CCP do not see this error when applying the license through the user interface.

Using Cisco IOS Firewall VPN clinet
Hello
I configured RTR1 to support VPN Clients. RTR1 has a site 2 RTR 2 site VPN tunnel.
Customer VPN connected to RTR1 have RTR1 LAN IP connectivity. How can I get the VPN Client LAN to access the local network RTR2?
I've included the VPN Client LAN to be ecrypted in the VPN tunnel to the LAN RTR2 and Vice Versa. I also tried a static router configured on RTR2 for the LAN of Client VPN IP WAN RTR1 serving of next hop.
Still doesn't work is not for me. Any ideas?
Thank you
The other side added your remote VPN client pool to its configuration? The remote site must know its interesting traffic as well. Is RTR2 NAT'ing? Cleaned the configs for the two routers would help a lot.

I tried ISA550 a config with the same constelations, but without suggesting.
Anyone has the same problem?
And had anyone has a tip for me, or has someone expirense with a site-by-site with ISA550 and Cisco 2821 ipsec tunnel?
I can successfully establish a tunnel between openswan linux server and the isa550.
Patrick,
as you can see on newspapers, the software behind ISA is also OpenSWAN
I have a facility with a 892 SRI running which should be the same as your 29erxx.
Use your IOS Config dynmap, penny, you are on the average nomad. If you don't have any RW customer you shoul go on IOS "No.-xauth" after the isakmp encryption key.
Here is my setup, with roardwarrior AND 2, site 2 site.

This is perhaps a silly question, but I am at a loss to see what the problem is.
I have a 515 on my site and am trying to install a few small 501 office across the country.
Each office can connect and establish a tunnel when I configure use EZ and I a setting up split-tunnel to pass to the Internet or to me every time.
If for some reason, I have to restart my PIX or my T1 goes down, they lose the tunnel (of course), but they lose also any Internet connection they have. The only way to get them reconnected to the world must go and uncheck the box "use the EZVPN."
At the end of the day, I don't want to then lose all connectivity when / if I get off.
What I forget?
Thanks in advance.

A hardware IOS with XAUTH client enabled on the client and the server requests a user name and password, which must be entered manually via cli.
Is it possible to store the user name and password locally on the client of equipment for xauth phase remaining without the invention of the user? The commands should be used on the client and the server?
Tanks in advance
Edgar
I guess that you have an IOS server also. The "Save password" option in the config of EzVPN has been added to the VPN server in T code 12.3 (2). Note This command is configured on the SERVER, and not on the client.
The client must be running at least 12.3 (4) T code to support this feature. After you configure "Save password" on the server, you will need to use the manual control on the client to build the tunnel once more. During the negotiation of the next tunnel, the customer is then notified that it is possible to save the password locally. Once this is done, follow this:
If you attempt to save the password on the client, it is enabled on the server, and without having to build the tunnel once more manually so that the customer is on the policy change, you get an error on the client by saying "Cannot save passwords" (or something like that).

Between Cisco ASA VPN tunnels with VLAN + hairpin.
I have two Cisco ASA (5520 and 5505) both with version 9.1 (7) with Over VPN and Security Plus licenses. I try to understand all the internet a traffic tunnel strategy VLAN especially on the 5520 above the 5505 for further routing to the internet (such as a hair/u-turn hairpin). A few warnings:
- The 5505 has a dynamically assigned internet address.
- The 5505 has sometimes no device turned on behind her, bringing interfaces down to the inside (which can cause problems from site to site).
- The 5520 cannot be a client of ezvpn due to its current role as a server of webvpn (anyconnect).
Let me know if I need to post my current config. Basically, I'm starting from scratch after several attempts.
Thank you!
- The 5505 has a dynamically assigned internet address.
You can use the following doc to set up the VPN and then this document to configure Hairping/U tuning
2. the 5505 has sometimes no device turned on behind her, bringing interfaces down to the inside (which can cause problems from site to site).
Make sure that the interface is connected to a switch so that it remains all the TIME.
3. 5520 the may not be a ezvpn customer due to she has current as one role anyconnect webvpn ()) server.
You can use dynamic VPN with normal static rather EZVPN tunnel.
Kind regards
