Cisco Security :: Fan Direction In ASA5510
Jan 16, 2012
I'm using a couple of ASA5510's since a few years in a few datacenters, and I wonder about the following:
Usually the ASA's are positioned with the connectors facing to the back of the 19" cabinets, so one can easily connect the device to other networking-hardware. In many datacenters nowadays, cold-coridors are used, which results in a forced airflow through the cabinet, which is empowered by the fans in the servers itself. But the ASA's are permanently blowing air in the opposite direction, and are also taking the air from the part of the cabinet where the air is as hot as it gets.
Is it a good practice to open up the ASA and flip the fans 180 degrees to solve this?

i have a strange issue on a link between two ASA5510: both ASAs are interconnected by a P2P Fastethernet link, and the traffic between both ASAs is being secured by a L2L IPsec tunnel. The configured MTUs are 1500, however packets bigger than 1020byte are being dropped. IOS is 8.0(5). I didn't find so far any CAVEAT describing it.

We want to have a ASA5510 with both IPS function and Content Security feature, while I checked on Cisco website, looks like ASA5510 or 5520 only have one SSM slot, so I can only use either AIP module or CSC module, does it mean I can not get both features at the same time.
Right now I want to have IPS function and anti-spam, anti-virus, antiphishing, content filtering, URL blocking such feature, so what do I need to buy to have all of these function in one device?

We have an ASA5510 with two ADSL lines connected and the auto fail-over set up - this is all tested and if the main line fails, the backup line is used in it's place - no problem there.
However, I'd like to increase our connection speed, and one way I've done this in the past is to add a couple of extra ADSL lines to a router that is capable of load balancing.
I'm aware that the ASA5510 does not load balance (seems a waste as we've got the backup line just sitting there doing nothing!), but would it be feasible to add another router in front of the ASA device to perform this load balancing function?

I have a 2811 ISR configured to provide the following services to my network:
Internet access to LAN users Cisco Call Manager ExpressSite-to-stie VPN to 3rd party networksVPN server to provide VPN access to remote usersSecurity Zone configurationsStatic NAT configurations Now I recently just got the ASA5510 device and I am not sure how to go about with the setup, whether to put the ASA in between the internet and the ISR (Internet - ASA - ISR - LAN), or put the ISR in between the internet and the ASA (Internet - ISR - ASA - LAN)? While i know I can move most of the config unto the ASA, i know that the CME cannot be moved, hence I would like to do the setup such that users on the network still have access to CME.

I have a ASA 5510 and planning to implement multiple context in a 2 tier security level and vrf-lite. meaning I have 2xASA facing the internet and below that a 2x3560 switch for our extranet and below that is another 2xASA for intranet. See diagram below. In this kind of network I want to know how it would impact the total throughput and resources of the ASA using multiple context?

I m getting mention error when try to open subjected web link.
Deny TCP (no connection) from Outside:180.87.10.44/2443 (180.87.10.44/2443) to DMZ-1:a.b.c.d/1594 (w.x.y.z/17964) with follow explanations.
"The adaptive security appliance discarded a TCP packet that has no associated connection in the adaptive security appliance connection table. The adaptive security appliance looks for a SYN flag in the packet, which indicates a request to establish a new connection. If the SYN flag is not set, and there is not an existing connection, the adaptive security appliance discards the packet."
Where, a.b.c.d = our private ip address (Natted) w.x.y.z = Public Ip address.

i'm about to configure a syslog server to receive syslog messages from a Cisco ASA5510 and being it a one week test I was wondering how much space should I allocate on the machine hosting the tool (kiwi syslog). I see that the ASA fills the internal syslog buffer to 4MB and then it overrides it. How many messages would those 4MB be?

I'm facing a problem with two vlans. Each vlan has internet access by NAT.
In each vlan there is at least one server, who should be accessible from the other vlan and vice versa.
The function "same-security-traffic permit inter-interface" doesn't work, because NAT control is in place - so an expert.
Some experts told me it's not possible to route back out the same interface, and also not route back out the seperate subinterfaces as well.

we operate an active/passive cluster with 2 ASA5510 in Routed Mode. Is it possible to add another node, so that we have one active and two standby nodes in the cluster? Unfortunately, I have found no documentation on this .... The data sheet say only up to 10 nodes can be mentioned as a VPN load balancing cluster.

Just recently we replaced our HQ Cisco-Pix with Cisco-ASA 5510. where we have many branches connecting to our HQ through site-to-site vpn. Since putting this new ASA5510 at HQ , while we are getting a Remote-Desktop session into our branches clients, and at the time when even a single TIMEOUT occurs on the vpn-link so the remote-desktop session gets completely lost. then we have to re-connect the session.This issue happens as i said above when a single timeout occurs on the vpn link. What is the issue with the ASA5510. because with pix we didn't have this issue, remote-desktops were never getting lost / reset with single timeout

I have to replace a 1230 with an 1262 AP.
All antennas have to be in the same direction on the AP and I guess when the old 1230 is working well the 1262 will be only better . Attached u see how I plan to mount the new AP versus the old one...

I'm very new to cisco devices but we recently acquired a catalyst 2911 device for our co-lo cabinet and I am trying to get a site-to-site vpn connection working between the facility and my offices network as well as a remote access VPN for me to use in case I have to fix something while outside of the office.
The office's gateway is 66.119.163.2 and the device is a TZ210 with it's LAN network being 192.168.1.0 /24
The co-los gateway is 204.244.50.254 and the device is an ASR 2911 with it's LAN network being 10.0.10.0 /24
The S2S VPN connection is up between the two locations and the 2911 device and the servers within it's LAN can ping and RDP to the office's machines. The office network can only ping the LAN interface IP on the 2911 which is 10.0.10.1 but not the servers in the network. the site-to-site VPN was set up with the CCP wizard.
How can I allow the 192.168.1.0/24 network to see the 10.0.10.1/24 network and why do I only currently see the gateway?
If need be I can post my running-config file with the preshare keys redacted.

I have lots of 857's routers in the field with mostly the latest OS - 12.4(15)T17 making ezVPN connections to a 2951 with 15.1(4)M5.All the 857's have lookback and vlan interfaces similar to :
interface Loopback0
ip address 50.43.8.1 255.255.255.255
ip tcp adjust-mss 1452
end
[code]....
Now lately for some or other reason we have instances where I can ping either the VLAN or the LOOPBACK interface, but not both. Or I have instances where the 2951 can ping all the interfaces on the 857, but the 857 can not ping the 2951. Or I have instances where the 2951 can not ping the 857, but the 857 can ping the 2951.The way I have been fixing this is either to add crypto ipsec client ezvpn SMS_VPN inside to the loopback interface, or if it is there already to remove it. This usually works for a few days, but then suddenly I have to reverse this again. If that does not work then I usually do lots of clear crypt sess and/or clear crypt ipsec client ezvpn on the 857, or clear crypt sess remote 857_ip_address from the 2951 and then suddenly it starts working again.

I have a IPSec tunnel that is working in one direction. Below is the router config from the side that can connect to the other side perfectly. I believe the issue is with this router as while I was waiting on delivery for the ASA I had an SRP527W sitting in it's place and had exactly the same problem.On one side I have a 887VA router and the other an ASA5505.The network behind the 887VA can access the remote site perfectly, backup services are traversing the link as are web interfaces for applications. In the other direction I can ping hosts but cannot connect. What else is interesting is if from the remote site I attempt to connect to a particular device that performs a port redirect the remote site browser gets so far as being redirected to port 5000 but then hangs.
I am seeing some very generic packet drop debug notices on the 887va on the NAT-ACL access list but I think this is as it should be as it is dropping the tunnel traffic from the NAT'ing.The config for the router is here, I will post the ASA config when I get to the other site shortly but I am convinced the issues is on this device, all the crypto configurations match.I have looked at the MTU's on each side, the path MTU on both sides is 1492. The asa does say the media MTU is 1500 but I believe that is the ADSL link so shouldnt matter?I even went so far as installing CCP and testing the VPN. It says the tunnel is up. It did state a failure:A ping with data size of this VPN interface MTU size and 'Do not Fragment' bit set to the other end VPN device is failing. This may happen if there is a lesser MTU network which drops the 'Do not fragment' packets. [code]

If a copy a file from my desktop to my laptop, the speed is usually 3 or 4 times faster than if I go in the other direction.
Desktop is connected to the router by a cable, laptop is wifi.
If I connect the laptop with a cable, speeds are fast both directions.
Router is a wrt54gl with dd-wrt. Both machines running Win7
Why would this happen? How can I identify the problem and fix it?

I know some business routers need to be registered to have certain functions work. I have gone through the knowledge base and there seem to be a few with my issues. Sadly I have been doing IT since 86 and playing with larger Cisco boxes for over a decade. So that's a little of my back ground, I also have a MCSE (W2K), A plus, Net Plus etc... so I know its got to be something stupid that I missed or something wrong with router. It was purchased new just before the holidays and I tried calling the posted Cisco number and the auto phone wanted a PO agreement before it would connect me. OK so alI need to do is Port forward two ports (3389, and 82) same ports internal and wan side. The internal is being sent to two different IP address, one per port config. So I did set up the UPNP, set up the service as enabled, and really looked in the knowledge base to see if I was missing something. So I left the site although just before I left I set up the remote admin login from the wan side. This does not even pick up, There is no other firewall between the device and the internet except for the T1 dmark.
This is a RV 08 new router so need a phone number for small business cisco for new products. I miss those good ole days where everything you needed to open and forward a port was located in one area in a router firmware setup.

I have 1x Cisco 6509 with Sup2 and MSFC2 and it is running on IOS (c6k222-jk9sv-mz.122-17d.SXB11). I have following policy map :
Policy Map VOIP
Class IP PHONE
priority percent 75
and the following command on each interface: service-policy output VOIP those configuration are working fine on SUP2 with MSFC2 but last week I tried to upgrade the SUP2 to SUP32 on the switch and upgrade the IOS to the latest version (s3223-adventerprisek9-mz.122-33.SXJ4) but when I try to put service-policy output VOIP on each physical interface I am getting the following error:
"Priority command is not supported in output direction for this interface" and when I try to add service-policy output VOIP on a V LAN interface I am getting following error:
MQC features are not supported in output direction for this interface. Will I need to change something after upgrading to SUP32..

For the purpose of a remote backup between 2 QNAP NAS devices, I have setup a site to site VPN using 2 Cisco RV220W routers. Although VPN connects just fine, I can only access Network B from network A, but not the other way around. I believe it could be related to ip ranges/subnets.IPSec VPN connects successfully (IPSec SA Established)From network A I can connect to any device on network B (qnap smb, ssh, cisco web interface, printer, laptops, etc)From network B, I can ping any device on network A, I can access the cisco web interface from network A, and nothing else. If I try to access the web interface for the qnap on network A from a device in network B, no luck, it seems to hang. I also tried issuing a wget command from the qnap (ssh) on network B to fetch the web interface of the qnap on network A, and it says connected, but then hangs. I've tried lots of different settings (creating static routes, dynamic routes, changing subnets, etc), but without any luck.
