Cisco VPN :: Configure IPsec Stateful Failover On 891?

Sep 15, 2011

We have purchased a couple of Cisco 891 routers - both are running IOS 15.0(1) M5 licensed with advanced IP services (default). The literature for these devices on Cisco's website claims they support IPsec stateful failover on advanced IP services.
Our intention is to configure them with HSRP and IPsec stateful failover to provide a highly-available default gateway and VPN end-point.
I have configured HSRP and that seems to work fine. My problem is that I cannot configure IPsec stateful failover. The documentation that I have found implies that I need to configure inter-device redundancy on a particular HSRP group and use the physical IP addresses on the interfaces within that group to allow stateful failover communication between the routers however the routers do not recognise the 'redundancy' command in config mode...
(config)# redundancy inter-device
% Invalid input detected at '^' marker.

Aug 21, 2011

I need to configure the ACS 5.1 to meet the following requirement :-
1. ACS 5.1 will point to a RSA SecurID as the first authentication mechanism for the validation of user credential

2. In the event that RSA SecurID is not reachable, the ACS 5.1 shall point to its local user database.
 I had no problem configuring for Point (1), but I am not able to let it failover to the local user database.

Cisco VPN :: Configure IPsec L2L To Allow Only One Way Traffic

May 9, 2011

We have a business need that we have to set up a IPsec L2L tunnel (from multiple locations) to a business partner, we require that the connection can only be initiated from our side, not business partner side. I searched the web, one option is configure our side ASA to initate IKE only, this does not seem to meet our requirement, because once IPsec SA is up, IP layer traffic will flow freely in either direction; the other option people suggested is to use VPN filter in tunnel group policy, but the documention of how to use this vpn-filter to enforce one way traffic policy is not crystal clear to me;  I actually configured reflexive ACL on core L3 switch before the traffic hits ASA to reflect/evalulate specific traffic to businness partner's LAN network, that worked well. However one of our branch office's core L3 switch is Cat4K which does not support reflexive ACL with the image it is currently running, so I am stuck again .

Cisco VPN :: PIX-501 IPSec To Configure Tunnel

Mar 24, 2011

I'm attempting to configure a tunnel on a PIX-501 version 6.3. It's an old device that's due to be replaced soon, but unfortunately we need a tunnel now... I have been using this document as a reference (6211): URL ,The remote end is a sonicwall.
The problem seems to be that the pix never sees the interesting traffic for the tunnel, and never tries to initiate a connection. I have enabled crypto ipsec and crypto isakmp debugs, but no data is ever displayed, even when attempting to access a device on the remote side of the tunnel! Someone had tried to set up this device with some tunnels in the past, but was never successful, so I'm thinking there might be remaining commands in the running-config causing problems.

Cisco Routers :: RV220w Configure For Ipsec Vpn Connections

Jan 2, 2013

I have an RV220w in office, which I have configure it for ipsec vpn connections. Behind router there is a NAS for file storage. [code]I have managed to connect to router from my home with ShrewVPN and I can ping every client connected to RV220w.The problem is that I can't connect to neither to router's web interface nor to NAS web interface or any other intranet web page ( the browser doesn't give any error, but keeps loading without showing the web page). Although, I can access web pages from my laptop.Also, in windows file explorer when I connect to NAS, although I can browse folders I can't copy files from my laptop to NAS and vice versa, I always get timeout error (I have checked the permissions to NAS and in addition I succeed to copy a small txt file 1kb, but no luck with bigger files).I also tried with QuickVPN client, but I had the same results. When I connect with pptp from windows everything works like a charm.My laptop has windows 7 64bit.

Cisco VPN :: ASA 5505 - Configure AnyConnect And IPSec VPN Connection?

Mar 3, 2012

This is for an ASA 5505. I  am trying to configure an AnyConnect and IPSec VPN connection and I think it's almost there  but not quite yet. When I login from an outside network it gives me the  following error for the SSL AnyConnect "The VPN client was unable to setup IP filtering" and "Secure VPN connection terminated by peer" for the IPSec. I previously had this working since Oct, but I was trying to modify it a  little to accept LT2P for native Android VPN clients and that messed up  everything that I had working perfectly. I checked everything as best as I could to try and match the previous settings but still can't get the darn thing to work. I am trying to also do Hairpinning, I want all VPN  traffic to pass through this router... remote LAN and Internet traffic  for times when I am at unfamiliar wifi hotspots and need to check email securely.  I have included my running config. I also need to configure the ASA to accept native Android VPN connections. I read the most popular thread that worked for a few users but while doing those modifications that is where everything went downhill. T

Cisco VPN :: ASA 5505 - Configure Allowed Bandwidth On IPSec Tunnels?

Oct 25, 2011

ASA 5505 8.2.1
ASA 5520 8.4 
We currently have a tunnel configured between 2 ASAs
1-  Is it possible to assign 1.5 Mbits of Bandwidth(BW) to this tunnel?. Then if Tunnel number 2 is configured I could assign 2 Mbits to that one for example?
I am not referring to prioritizing certain type of traffic over the IPsec tunnel, I am referring to Tunnel 1 has 1.5 Mbits of BW guaranteed for all traffic that goes thru it. Same for tunnel 2
2- How to monitor the amount of BW in an IPsec tunnel?
