I was wondering if the ASA 5520 Firewall had the ability to view web traffic or site surfing or does this only work if I have a logging server configured for the ASA to log to? I don't use the ASA much since I'm the database administrator for my company but from time to time I'm asked when nobody else is available. I just checked the ASDM & see that the buffer clears after so many lines & I don't believe we've got a logging server.
We are using the ASA 5520 as Firewall and VPN gateway for remote access by employees and vendors. Is there a way to view a history of VPN user logins? We used to have (or we still have but no longer using it) th CVPN 3005. This device keeps log files of all activities. I miss having this capability in the ASA 5520.
I am currently using ASDM v6.4 and would like to enable the historic metrics feature to view/produce graphs/tables for interface using the Last 5 days, every 2 hours option. how this will impact performance and storage space on the device?
After command clear route, all timers just continue, there is not actually clearing the routing table... This is happening on two different boxes: pair of ASA 5520 and one 5505 ASA... I presume it is happening on all others too, but I don't have this release installed anywhere else...

I have a simple network with an ASA5505 mainly used for AnyConnect so there is little traffic. There is 1 laptop connected to the E0/1 of the ASA and then E0/0 is going to the internet port. I've noticed about ever 15-20 minutes, I lose all connection. The laptop can no longer browse the web and handsets can no longer VPN into the network. I've noticed a few seconds after performing a clear arp, all the connectinos are restored. The laptop can browse the web and handsets can VPN in again.
My Expertise with Cisco ASA is Very less. I have observed Input errors in a Couple of Interfaces in Cisco ASA 5540 Firewall. [code] I need to Clear the Input errors on this particular Interface.Will Clear interface GigabitEthernet 0/0 will work?
I am redoing my homes networking and I am looking for a firewall. I heard that you can install clear os on a server and use it as a firewall and a dhcp server. So i was going to install it on a rack in my server cabinet. does the server need to have a wan port and a lan port? Or how does the server get connected? So, so far its the cable modem into the clear os firewall and then into my switch. Is is possible to use the clear os server as the dhcp server for the whole house? From the switch I am going to connect the rest of my servers, and the rest of the house. I was going to connect two wireless routers for my house. Would that work with the clear os server?
I'm running a cisco 891 with ios Version 15.2(4)M3 ,now I have a dialer 0 interface with fast0 and 1 as well, all is working fine.now I just read about the new sh int 'INT' history feature but when I do it I get nothing.. not a graph or anything I get just nothing as if I just hit enter.anything I need to do to enable the feature?,if I do a sho proc cpu history that works just fine but not the sh int XYZ history commands
I'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.
We are using the newest release of AD Agent (18.104.22.168.1, 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:
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.
Two different WAN links get connected to the firewall via two routers.(Different ip subnets).I need to get this two wan streams seperatly to the core switches.Core switches sits.Active/Stanby senario. If the Active core goes down Stndby Core will have take over the traffic. My design is correct ,if not what do i need to change. ASA is 5520.
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.
Last logs I received before crash were:

we are having a firewall asa 5520 .we have connected the management port and inside port to internal network and dmz port to dmz network.now we need to configure tacacs and other management tool on dmz devices through management port. The problem is the management devices tacacs and other are placed in internal network.
I 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?
Our Local Network is behind the CISCO ASA Firewall.Whenever we are accessing to Client VPN server,it is getting connected but after few Minutes (May be 5/10/30 Min),the sessions are terminating. The same traffic through PIX is no issue , only with ASA Firewall. See the following Error and request you give the possible root cause for this.

I have problem in the configuration of Cisco ASA 5520, IOS version 8.4. The connection is as follows: LAN network--> Firewall --> Routers with GLBP with virtual ip address. the clients can not ping the virtual interface of the GLBP group, but I can ping it from the firewall, and I can ping the clients from the firewall, I checked the packet tracer it gives :
Phase: 7 Type: NAT Subtype: Result: DROP Config: nat (inside10,outside) source dynamic LAN interface Additional Information:(code)
Our enterprise uses a VPN Concentrator 3000 for our VPN access. Is there a way to view a log history of what user connected to VPN and what IP address they were assigned? It would be for 2 days ago which was over the weekend.
I want to do something with IP SLA and started by estabilishing a baseline.
I'm trying to check history on an ASR. I tested same config on a 3845 and was forgetting the "history filter all". After this I could see history table on 3845 but still history is empty on the ASR1006. The operation started because I can see information with "show ip sla statistics".
know if i missed something or maybe this is not supported in ASR1006?

I have been appointed to monitor an internet networking consist of 4 computers.
1. To block some websites for all 4 computers. Example, maybe if I want to block YouTube - Broadcast Yourself. or any website. This is actually to prevent users to access any adult site.I dont want to block internet entirely. But just to block some website only.
2. To have a report for internet URL for each computer. Not a bandwidth or traffic report. I dont need that. What I want is a list of URL that the user have surf in the internet.
