I have two ASA 5520 units, both running version 8.3(2) code. Among many other uses, they have an IPSec tunnel between them to link office 1 and office 3 together. Office 2 does exist, and is connected to a different port on the ASA in office 3; there is no IPSec involved with office 3.

How can I see the quantity of traffic that is passing through into an IPSec VPN in a ASA 5520.
View 3 Replies View RelatedI am working on IPSec Passthrough on an ASA 5520, with version 8.3, and ASDM 6.3. Currently I have a requirement for users in my internal network (10.10.249.128 / 25) to be able to connect to external IPSec VPN servers.
So I created a network object with 10.10.249.128 / 25, and used dynamic PAT to translate the source ip address to the external internet facing outside interface:
I then added the following rules on the inside-in ACL: However troubleshooting shows that isakmp is passing through the firewall, but esp and ah is not.

I'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?

We have used two Cisco RVS4000 to create the IPSec VPN between the main office and the branch office. The main office has SBS 2008. There is a Windows Server 2008 as the domain controller in the branch office. One branch office user has a laptop which is not in the domain, but his exchange account is set up in the Outlook. When he connects the laptop to the branch office network, he cannot connect to the exchange server and get the emails. Is there any configuration to set up in the router, server or Outlook?
View 1 Replies View RelatedWe have AT&T Managed MPLS service are our datacenter and our branch office locations. AT&T has provided the routers and simply give us an ethernet connection. We also have ethernet connectivity to the internet through our datacenter...with our network being protected by an ASA 5520.Each branch location has a 29xx series router (voice gateway) and switching gear attached to their AT&T MPLS router. Some of our branches also have 3rd party cable internet service with an ASA 5505 to protect it from the internet. What I'd like to do is better utilize this cable modem/ASA5505 setup. Right now, if there were an outage, I would be connecting manually to the remote location to change static routes to point to the cable link and to configure a VPN tunnel between the remote and our DC.
View 2 Replies View RelatedI have a home office with multiple VLANS/subnets I have many VPNs that connect only a specific subnet to a specific remote offfice. On a 5520, can I create a S2S VPN to different remote offices that have the same IP scheme, but from different home office subnets? For example at my home office let's say I have two independant, distinct VLAN/subnets: 192.168.140.0/24 and 192.168.150.0/24. Can I create an S2S from the 140 subnet to a remote office with a 10.10.10.0 addressing scheme and another S2S from the 150 subnet to a totally different office also with a 10.10.10.0 scheme?

View 7 Replies View RelatedCurrently 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.
View 8 Replies View RelatedThe 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.
I 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?

View 2 Replies View RelatedCurrently 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.

View 5 Replies View RelatedHere 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.

View 9 Replies View RelatedI 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.

View 6 Replies View RelatedI 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.
