We have asa 5520 with 8.4(2) release and asdm 6.4(5). When we create new ipsec connection profiles (by ipsec wizard for example), ASA reset all vpnclients sessions active. Now we need to create new profiles, but we have 170 vpnclients sessions active, so we cant'.

Cisco VPN :: ASA 5520 - ASDM Shows Lot Of IPsec VPN Sessions In GUI

Jan 20, 2013

I have upgraded my ASA 5520 til version 9.1 with ASDM version 7.1. After the upgrade ASDM shows a lot of IPSEC VPN-sessions in the GUI that i cannot see from the ASA. Right now the GUI says that I have 28 IPSEC-sessions while the output from "show vpn-sessiondb l2l" shows the expected 4 tunnels and the output from "show vpn-sessiopndb remote" shows 0 as expected. (I do not use IPSEC from remote users).

Cisco VPN :: 5520 ASAs - IPSec VPN Clients Not Being Able To Connect

Aug 25, 2011

I am currently having some problems on our 5520 ASAs. The problem is the IPSec VPN clients not being able to connect. We have had an issue twice this week where this happened. Earlier in the week we had folks not able to sign in, but some folks who were connected already stayed connected. The ASAs had been up for 200+ days and no changes have been made to it recently. At that point I had to reload the ASAs so users could start signing back in to it. Today we had a similar issue, but I didn’t have to reload the ASAs. The issue‘resolved’ itself. The VPN clients are getting Error code: 433 and the ASAs are getting Reason: Peer Address Changed when this occurs.

Cisco VPN :: 5520 / 5510 - Can VPN Clients Communicate With Other Dynamic Clients

Nov 5, 2012

We currently have an ASA 5520 communicating with 10 ASA 5510's, all on static outside addresses.  I was asked to add 5 additional 5510's on dynamic address.  All worked well in testing until it was decided that some of the dynamic clients needed to talk to each other.

My testing shows packets just dying in the 5520.

I need to create multiple ip-sec vpn tunnels on A Cisco 837 ADSL Router. I am able to create one tunnel but the second connection is asking for the outside interface which is atm and already taken by the first tunnel. How can i create more tunnels?
Secondly, after creating the first tunnel i am able to access the remote lan network but when i tried tracert "remote lan ip of a pc" from my pc i got "request timed out" after passing my 837 but succeeded to reach the target. Does tracert needs something to be opened in the router?

Cisco VPN :: VPN 3000 Setting Two Concentrators At Different Sites To Create Ipsec Tunnel

May 20, 2011

I'm currently setting up two VPN 3000 Concentrators at two different sites to create a IPsec LAN-to-LAN Tunnel. I have gone through all the basic configuration guides on the CISCO site, but a LAN-to-LAN session is never created. I have enabled the logs on the Concentrator and it displays no errors at all - it appears the Concentrator is not even trying to establish a IPsec LAN-to-LAN Tunnel.After running through the standard setup provided by CISCO, is there anything I need to do to make the Concentrator try to create a Tunnel, or should this be automatic once all settings are in place?

Cisco VPN :: 5520 - How To Create VPN Design

Apr 3, 2011

i need to design a site-to-site VPN and VPN for remote users. I have attach a drawing, need to know if this is good setup. Mostly my concern is security. Im using ASA5520 for edge firewall and Linux firewalls are for additional security.I have to create 5 site-to-site VPN using IPSEC and 5 remote VPN clients. Site-to-site VPN are for trusted Office and remote VPN clients are only for our staff use.
From the diagram ASA5520 is configured as followed
outside interface is set to security 0 and connected to boder router to internet, inside interface is set to security 100 which is connected to a linux firewall which then goes to our internal lan.DMZ interface is set to security 50 which is connected to DMZ segment ,I decided to use the 4th interface for all VPNs which is set to security 100, and for this 4th interface i have created two sub interfaces vlan 400 (for site-tosite VPN) and vlan 500 (for remote access VPN). I did this because i have to use two separate linux firewall box. Linux firewall box for Site to Site VPN is configured with NAT but Linux firewall box for remote access VPN users are configured without NAT. I also want to know do i need to create a CA server or can i use pre-shared key with XAuth for remote access VPN users?

Cisco Firewall :: Is Multicast Supported On ASA 5510 For IPSec VPN Clients

Dec 6, 2011

Our customer is using multicast in their internal network for their IP video deployemnt. Internallt on the network everything is working great.
We have two folks in management who want to be able to view the live multicast video feeds of the cameras remotely. I have tried to accomplish this using the Cisco VPN client. Although VPN connectivity is good (we can ping the individual cameras) they are unable to view the live multicast feeds. I enabled multicast globally on the ASA and the inside interface and get the same results.
Is there a way for the ASA to support the remote IPSec VPN client to view the multicast strams?

Cisco VPN :: ASA 5520 - Connecting To AnyConnect Clients By IP Address

Feb 8, 2011

I have setup an AnyConnect Connection Profile on my ASA 5520.
We have some remote support software which the helpdesk use to connect to PC's remotley and torubleshoot.
I cannot connect to this software using the assigned IP address of the client even though it works fine with our old Nortel VPN.
If I hit the IP address the packet gets all the way to the ASA and seems to disappear.
I have setup an IP v4 access list on the connection profile which allows any/any access b ut still no joy.

Cisco VPN :: ASA 5520 8.2(3) - Allow Remote Clients To Access Other Networks

Oct 24, 2012

I have an ASA 5520 8.2(3) and allowing my remote client-to-site-vpn clients to access resources directly connected to my ASA on separate lower security interfaces (not the outside) besides just clients on my internal networks.  Someone mentioned to me configuring 'VPN on a stick' however from what I've read this seems to be only applicable when it comes to split-tunneling back out the outside interface (could be off on that).  Is this possible on other lower security interfaces as well, and if so what would a mock config that accomplishes that look like (acl's, nat, etc)?  Also, if I want internal users to be able to connect to these remote clients once they are active, are there any nat statements necessary (such as nonatting them) or are the vpn clients just seen as internal clients from the rest of the internal network's standpoint by default?

Cisco Firewall :: ASA 5520 - Create Network Object For Range Of Hosts?

I'm migrating our network objects from our current firewall to a new ASA 5520 configuration. I'm using ASDM 6.4 for configuration.
We have a range of IP addresses for hosts that we need to add to a firewall rule/ACL. In the previous FW software I could create an object that was a range of IP address. For example there is an object called emailservers that is defined as
Is there a way to do a similar thing on the ASA 5520?
I can see how to create subnets, but in this case I only have a range of IP addresses, no subnet mask.

Cisco VPN :: 5520 Should SSL VPN Performance Be On Par With IPSEC

May 22, 2010

Currently running a pair of 5520 as VPN routers. running 8.0.3, been using only Anyconnect SSL VPN for end users. These boxes do nothing else except serve VPN clients.However, recently we tried testing some IPSEC clients and are realizing that the Anyconnect SSL VPN clients is about 10x slower than the IPSEC client.From my house, downloading either CIFS or FTP, I can pull pretty close to 1.0mbps, while using Anyconnect, I pull 0.1mbps. What could be causing this slowdown? Should SSL VPN performance be on par with IPSEC? Clients all are windows 7, 64 bit. and the testing is being conducted on the same device.

Cisco :: Routing And IPSec On ASA 5520

Nov 19, 2011

The network design is a hub and spoke using a carrier provided MPLS network with a ASA 5520 at the hub that has a IPSec tunnel to another part of the company.This configuration has worked for sometime now (long before I came to the company a couple of months ago).The thing that does not make sense to me is that the those networks out on the spokes did not have a route to the inside interface network of the ASA. With the way this MPLS works, if a network is not in the MPLS network routing tables it will not pass that network. The network was not in the MPLS network, nor was it in any of our edge routers connecting to the MPLS.
These hub networks did have routes both in the MPLS and edge devices for the networks on the other side of the IPSec tunnel and have been reaching them for some time.So what I am trying to understand is how it is possible for these hosts that have no route to the ASA inside interface network, but do have routes to the remote networks, how are they able to successfully pass that traffic? There are no NAT devices between these WAN hosts and the ASA.
