i have ASA 5520 , some times the CPU Spikes above 90% for 5 Seconds then it went down to 35 - 40% ,but what happened when it shoots to 90% all connection go through this ASA gets drops then i receive complain since application traffic traverse this FW ,so how can i see the CPU History for last 1 week , i need to see the times and the date WHEN THE CPU went above 90% for 4 seconds.

View 1 Replies View RelatedI'd like to see some REAL LIFE comparisons of ASA firewall throughput (a bit like this one for ISR G2 Routers - [URL].
The reason I ask is that I recently upgraded a firewall from an ASA5505 to an ASA5520 on a small network where the only outside connectivity was a single 10meg Internet circuit with an IPSEC VPN (not landed on the firewall but on a router) to another site.
When I swapped out the firewall the users noticed a big improvement. The firewall is not doing anything out of the ordinary - no IPS or VPN, just standard state full inspection.
I have an asa 5520. How would I configure my dedicated management interface to be able to route off subnet while the firewall is in transparent mode?
View 1 Replies View RelatedWe are using the newest release of AD Agent (1.0.0.32.1, built 598). The ASA Firewalls 5520 are having the software release 8.4(3)8 installed.When somebody tries to connect thru the Identity based firewalls from a citrix published desktop environment (PDI) the connection is not possible. Checking the ip-of-user mapping on the firewalls (show user-identity ip-of-user USERNAME) mostly doesn't show the mapping of the USERNAME and the PDI the user is logged in. The user-of-ip mapping of the PDIs IP-address shows mostly other users, which then are used to authenticate the acces thru the firewalls.
What is interesting, that on the AD Agent using "adacfg.exe cache list | find /i "USERNAME"" i can't see the PDIs IP-address neither because it is mapped to another user.Is Citrix Published Desktop environment supported to connect thru Identity based Firewalls? How AD Agent, Domain Controllers and Firewalls are working together? On the firewalls with "show user-identity ad-agent we see, the following:
-Authentication Port: udp/1645
-Accounting Port: udp/1646
-ASA Listening Port: udp/3799
Why Cisco does use 1645 and 1646 and not 1812 and 1813?The Listening Port is used for what purpose? we tried the AD Agent modes full- download and on-demand with the same effect.
I try to launch a LAND Attack against my firewall ASA 5520. Everything will work fine. But why, I think it should not work. I use a little tool where I can user a spoofed address, with a cluster shell and attack the firewall interface with the source of 127.0.0.1 ore the ip address of the interface as the source and destination. Then I get a cpu load of 89% with only two host. With IP tables I can use kernel processes to prevent this. But I don´t find anything for ASA.

I have a serious problem with my corporate firewall, witch is an ASA 5520, fv 8.3, with 8 +1 interfaces. It suddenly started to crash every 10/20 minutes and rebooting alone.
First of all I checked system resources witch are in a very low usage state. I also checked interfaces errors, but nothing strange come out o from error counters analysis. I tried disabling logging and all the service policy rules configured, but nothing changed.
Nothing changed and firewall continue restarting by itself.

View 2 Replies View RelatedI have an ASA 5520 in my company which does all our NAT and Firewall access control. Currently there is a rule in place to allow an incoming connection on port 2222 from a specific ip address to allow access to a web app our developers created. This is a test before the web app is released live. Now the web app can communicate with the specific address and port but the incoming connection on port 2222 isn't getting through. Everything looks great in the firewall but how can I log any hits this ACL takes to identify any potential problems?

View 2 Replies View RelatedTwo days ago, we changed our old 525 with asa 5520 ( ver 8.2 ). Configuration is the same, except the version. It even retains the same global interface and static public ip address as the old device.All worked well during that period.
Yesterday, one of the http applications , not tested other day, was found not to be working. To test, we switched back to the old 525 , however nothing was working when we did that.
Since about a week ago, my room-mates and I have been getting lag spikes on the internet when more than one of us are on the internet at once, yet the connection is perfectly stable when there is only one active. ( Does not matter which one. )
I've run Avast, AVG and CCcleaner, on all the computers and the spikes still persist. I've also replaced my router with no results. Here's my system info and some tracerts showing the lag spikes
System info:
Tech Support Guy System Info Utility version 1.0.0.2

About 2 weeks ago I have been getting lag spikes on my xbox and PC games, this never happened.I have no problem playing the game, no lag. Apart from these spikes that happen every 10-15mins.They last for about 5-10 seconds and seriously affect my game. (I get killed)
Would switching channel through the 02 Wireless internet control panel fix this? Am I on a bad channel?p.s. It is not possible for me to haveit wired, wireless only.
I've been having problems with my internet on my PC. I use it mostly for gaming (League of Legends specifically but it's also hooked up to my Xbox for internet connection), and I frequently (about every minute or so, sometimes more) get bad lag spikes when playing games. My character will freeze in place while I click wildly about and then appear somewhere else (and die or lose a kill).
The thing is, I'm connected to my Apple Airport which all other devices in the house are connected to (Wii, dad's Mac desktop, my Mac laptop), and only my PC gets this lag. Seems like a fairly generic problem but I have no idea what to do about it, so if you need more information let me know.

I have reason to be suspicious as to the game's relevance. These spikes are characterized by no packet loss, as measured by pingplotter and winmtr (more specifically, there is packet loss, but I've come to understand that because it does not continue on to subsequent jumps it's not an issue), and latency leaping to between 250 and 600ms across multiple hops, seemingly without pattern or form, for intervals
Here are some summaries of some extended pingplotter sessions. The suspicion that this is not entirely WoW related is recent, so I'm working on seeing if I can get similar results from some other sources.

Random lag spikes - YouTube
I am playing a game, like Battlefield Bad Company 2. Every 5-15 minutes, I get 3 lag spikes. When I get the lag spikes, everyone who is using my internet, also gets it the same time as me. So my computer is not the problem.For example: I am just running, shooting people (online), and then, randomly, people are running on the spot for like 3 seconds, and then they teleport somewhere in front of them. And then it goes back to normal, then it happens again. It will happen 3 times.

I did not have this issue on my laptop, nor do I have the problem with my wife's laptop. Is there any sort of setting in the bios that might affect this that I am overlooking?I'm about to just call timewarner and have them relocate the cable modem to this room so I do not have to deal with wireless.

While browsing the interwebz I don't really notice the lag spikes because they are only a few seconds long.Changes I have made (PC):

Disabled ANOD Network Security Filter driver
Disabled QoS Packet Scheduler

I have Planet modem ade-4400 linked to a Digitus ethernet Dn 5001a that I use to connect my 2nd PC.The problem is that everytime, both PCs are connected I constantly get lag spikes while playing games.Also, seemingly on random occasions, no matter what programs I run in the background my connection gets disabled with a yellow exclamation mark over my network icon. I get a "The default gateway is not available" error once I troubleshoot, and the connection works fine afterwards.
However, recently after I updated the windows I think, I get another error that says "The connection between your access point, router, or cable modem and the Internet is broken" along with the gateway one. Also, recently, I started having lag spikes regardless of the other computer being connected to mine after the error, and once I turn on my pc. Could it be somehow related to Microsoft security essentials? Since I've installed it at about the same time when the lag-after-the-error started happening.
Error seems to happen more often when I watch something on the internet, or when I quickly browse through the web-pages, or when I'm downloading something. I'm using Windows 7, and another thing to note is that the other computer DOES NOT receive these kinds of errors, and I do believe it does not lag while playing games.The lag after the error and after I start up my pc goes away after some time.
My father recently bought a laptop with windows7, and while it is connected to the internet through the router, there is a lag spike every 20 or so seconds, which also shows up when pinging the router as a jump in ping. This happens wired and wireless and also affects other connections on the network (my desktop computers also get a spike in ping). I have isolated the problem to be with the laptop, because as soon as the laptop is disconnected from router completely there is no more spike in ping
