Aug 4, 2012I tried looking in ASA documentations but unable to find out that how many IPSec Tunnels can be terminated to an ASA cluster. I have 5545 running only two IPSec Tunnels so far but need to terminate 18 sites all up and would like to confirm how many tunnels we could terminate? Is there a limitaion to it?

Feb 14, 2011I'm trying to gather netflow data over an IPSEC VPN and through my research I've learned that I need to configure Flexible Netflow. However, I have a Cisco 2801 router with the latest ROMMON and IOS and the Flexible Netflow options aren't available.
For instance:
flow exporter dwtmonitor
destination 10.0.16.172
source Loopback0
transport udp 2055
output-features
When I type "flow exporter <name>" it only allows me to enter "flow <name>" and there's no "destination" options or anything else.
ROMMON: 12.4(13r)TIOS: 12.4(25d)
Cisco Routers :: RVL200 IPSEC Channel All Or Some Data Traffic Through Tunnel
Jan 2, 2013Is it at all possible to channel all/some data traffic through an established ipsec tunneled connection using the RVL200? I have successfully established an ipsec connection through RVL200 and RV042 routers and are able to connect to servers/computers behind it.Now I want to channel all or some traffic through the ipsec-tunnel for computers that reside on 192.168.1.0 subnet of RVL200 network.
Main office - RV042 router - 10.200.62.1
Remote office - RVL200 router - 192.168.1.1

Cisco VPN :: 5520 Should SSL VPN Performance Be On Par With IPSEC
May 22, 2010Currently 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.

Nov 19, 2011The 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.
Cisco VPN :: ASA 5520 IPsec VPN Performance?
Feb 17, 2011I have a client that uses the ASA 5520 as both a firewall and VPN termination device. Day to day VPN usage is 30-50 users and the memory (512 MB) is typically at 50% while the CPU is mostly under 30%. I've suggested the RAM be upgrade to 1GB.The client would like to add a large block of VPN users which could see 250-300 concurrent users. What kind of a system resource hit should the expect with this level of load?

Jun 24, 2012I have made the following change to my ASA 5520 using ASDM to try and force VPN clients to use a self assigned certificate from the ASA. I made the following changes Remove Access VPN > Certificate Management > Identity Certificates > Add Certificate.Then I made the following change.. Remote Access VPN > Network (Client) Access > IPSec(IKEv1) Connection Profiles > Connection Profile > Edit > IKE Peer Authentication > Pre Shared key and pointed the identity certificate to the one I created in the step above.Having made this change I am still able to VPN without a certificate configured in authentication settings.I was expecting that the VPN would attempt to issue the self assigned cert to client machine?

May 28, 2012Currently we are having a 2 ISP for Internet. Need to achieve redundancy for IPSEC VPN using the domain.
Requirement :Will configure a domain and assign two public IP address from 2 service providers. Will set the priority for the public ip address and do the manual change during the ISP failure.We will provide the domain name to the clients to setup the IPSEC VPN.So incase of failure by one ISP, we will change the priority in the domain to point to the availble address.So that we can reduce the downtime and no need of configuring new IPSEC VPN tunnels.
Question :Whether we can achieve this in Cisco ASA 5520.Or do we have an alternate solution to overceome this solution.

Apr 4, 2011Here is the situation: A CISCO871 router is configured to establish an IP SEC tunnel with a CISCO ASA5520. The configuration is OK about that. I wish to configure the same CISCO871 in order to establish a LAN-to-LAN IP sec Tunnel with another CISCO871 at the same time in order to reach private network. So, I have followed the Cisco procedure Document ID: 71462 "LAN-to-LAN IP sec Tunnel Between Two Routers Configuration Example"; it works, I can reach the peer private network BUT ONLY when the IP SEC tunnel with ASA is not established.
It seems to be a routing problem...I don't find how to configure to make both tunnels up and functional at the same time.

Aug 25, 2011I 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 / IPSec VPN Won't Initiate From Remote Site
Sep 8, 2012I have a site-to-site VPN configured between a 5520 at our data center, and a 1700 at a client's site for site-to-site connectivity. What I've noticed is, is that the VPN can only initiate from my Data Center, never from the client router. I can telnet into the router and start a telnet session sourced from the "inside" interface and it fails, yet I can see the NAT translations get created in the state table that should match the crypto-map. However, if I ping a host on the inside of the remote LAN from my workstation (behind the 5520) to bring the tunnel up, and run the exact same command on the client router once the tunnel is up, it works. Right now I have a continuous ping running from my workstation to keep the tunnel up, but obviously that's not the best solution
I had to modify this config to NAT the LAN addresses at the client to a non-overlapping subnet, so anything coming from 128.1.0.0/16 should be NAT'd to 192.168.105.[50-200]/24. I've also got two static NATs for inbound access from the data center and those seem to work fine.

Cisco Firewall :: ASA 5520 - IPSec Tunnel Without Private Network
Apr 11, 2013I'm trying to achieve a site-to-site ipsec tunnel to a Cisco ASA 5520. Most examples feature the ASA with a public interface that terminates the tuennel and a private network on another interface that the tunnel interacts with. Where my scenario differs is that the interface that accepts the tunnel is part of a public /29 network where I want the remaining hosts on that subnet to be able to route thrugh to the other end of the tunnel. My tunnel gets established, but any attempts to route via the IP assigned to that one interface result in the ASA rejecting traffic. If so, what configuration options should I consider?
