Cisco Firewall :: ASA 5520 - ASDM Logging - Disable Rules Logging

Nov 16, 2011

I'm encountering what I think is an issue on logging system on FW ASA 5520 - Asa Version 8.4(2), ASDM version 6.4(5). When I disabled the logging inside a rule from ASDM, or from console with the "log disable" option inside ACL, If I check in ASDM logging real time window I continue to see all the entry related to disabled rules. This is a correct behaviour about ASA logging ? How I can "hide" the entry related to disabled rules (this is what I need for troubleshooting purposes) ?

Cisco Firewall :: 5520 ASDM Logging Does Not Appear Correctly

Jun 21, 2011

I have a problem with my ASDM Logging(ASA5520, System image file is "disk0:/asa804-k8.bin").If i generate any traffic, the ASDM do not show the packets correctly. For example, if i generate a icmp traffic from interface inside to outsite, the ASDM does not show the packets, when it shows it apperars just in one direction.

I'm on the ASDM of a 5510 and the logging with in the ASDM is currently set just right, but when I go into the console via SSH and use "term mon" I don't get this logging showing up.

Cisco Firewall :: ASA 5520 - Add Rules Through CMD Prompt As Against ASDM

May 28, 2013

We have a pair of ASA  running 8.0 (old) version.  The way we create outbound rules is done through ASDM and when we need to open outbound connections to a server in the internet, we create named object with IP address configured manually.But practically , this doesnt work, since  the server is a server name which can resolve to multiple addresses. Everytime the server chagnes its IP the ASA rule needs to be updated.Is there a difference if we add rules through CMD prompt as against ASDM where we need to enter IP addresses?

Cisco Switching/Routing :: 2811 Disable Audit-trail For Icmp Packets In CBAC Logging

Mar 23, 2013

I have a cisco 2811 router set up as a nat/firewall gateway for my network. I've configured it for CBAC on using ip inspect and an access list.What I want is to use audit-trail to record network traffic (which means sending syslog messages to a server) concerning established sessions from my own network to locations in the outside. If i configure this using ip inspect audit-trail and no ip inspect alert-off, the configuration looks like this: [code] which works just fine, but there is the matter of icmp packets.
 
Since i use polling software that needs to check some machines in the outside part of the network, it is only natural that several icmp sessions are established through the Inspection Rule per minute. The problem is that since these sessions are recorded along with everything else, my syslogs are flooded with these (since i am using logging trap informational) to the point that more messages are generated about icmp than all other traffic combined, especially in non-working hours.What I am asking is a way for the audit-trail to be selecively disabled for icmp, so that the outgoing (echo) &incoming (echo reply) sessions can be established without generating syslog messages.

What are the exact steps required to recieve the above format? If the logging needs to be enabled on Access Lists, need exact commands, from the console config mode?

Cisco Firewall :: ASA 5585- TCP Syslog / Logging Permit-Host Down

Jul 5, 2012

We have a firewall service environment where logging is handled with UDP at the moment. Recently we have noticed that some messages get lost on the way to the server (Since the server doesn't seem to be under huge stress from syslog traffic). We decided to try sending the syslog via TCP. You can imagine my surprise when I enabled the "logging host <interface name> <server ip> tcp/1470" on an ASA Security context and find out that all the connections through that firewall are now being blocked. Granted, I could have checked the command reference for this specific command but I never even thought of the possibility of a logging command being able to stop all traffic on a firewall.
 
The TCP syslog connection failing was caused by a mismatched TCP port on the server which got corrected quickly. Even though I could now view log messages from the firewall in question in real time, the only message logged was the blocking of new connections with the following syslog message: "%ASA-3-201008: Disallowing new connections."
 
Here start my questions:
 
- New connections are supposed to be blocked when the the TCP Syslog server are not reachable. How is it possible that I am seeing the TCP syslog sent to the server and the ASA Security Context is still blocking the traffic? 
- I configured the "logging permit-host down" after I found the command and it supposedly should prevent the above problem/situation from happening. Yet after issuing this command on the Security Context in question, connections were still being blocked with the same syslog message. Why is this? 
- Eventually I changed the logging back to UDP. This yet again caused no change to the situation. All the customer connections were still being blocked. Why is this? 
- After all the above I removed all possible logging configurations from the Security Context. This had absolutely no effect on the situation either. 
- As a last measure I changed to the system context of the ASA and totally removed the syslog interface from the Security Context. This also had absolutely no effect on the situation. 
 
At the end I was forced to save the configuration on the ASAs Flash -memory, remove the Security Context, create the SC again, attach the interfaces again and load the configuration from the flash into the Security Context. This in the end corrected the problem. Seems to me this is some sort of bug since the syslog server was receiving the syslog messages from the SC but the ASA was still blocking all new connections. Even the command "logging permit-host down" command didn't wor or changing back to UDP.
 
It seems the Security Context in question just simply got stuck and continued blocking all connections even though in the end it didn't have ANY logging configurations on. Seems to me that this is quite a risky configuration if you are possibly facing cutting all traffic for hundreds of customers when the syslog connection is lost or the above situation happens and isn't corrected by any of the above measures we took (like the command "logging permit-host down" which is supposed to avoid this situation altogether).

Cisco Firewall :: ASA 5505 Using Logging & Packet-capture To Locate Virus Infected PC

Aug 2, 2011

ATT notified my company we have a virus infected pc on one our networks which sits behind a Cisco ASA 5505 running 7.2(4). The set up is a basic inside/outside NAT configuration. They gave us the destination ip address and port which the our pc is contacting.  I have been tasked to track down the infected pc.  I created the following access-list and applied to the inside interface:
 
access-list VIRUS extended permit TCP ANY host x.x.x.x EQ YYYYY log debugging interval 600 access-group VIRUS in interface inside
 
I enable logging to the console whose output did not list the IP address of the infected pc, only the ip address of the DNS servers we were using. I then used the following capture commands to try locate the internal ip address of the infected pc:
 
capture in-cap interface inside access-list VIRUS-CAP buffer 1000000 packet 1522 capture in-cap access-list VIRUS-CAP interface inside
 
Neither step worked and the resulting console output overwhelmed the firewall in a very short period of time. Before attempting this task again, I would like to know if I am going about this the right way or if there is a better methodology?

Cisco Firewall :: ASA 5520 Difference Between Access Rules And ACL / ACE?

Nov 2, 2011

We are moving from a different vendor to ASA 5520s. So far my "training" for Cisco consists of s  Cisco press book, some white papers and guides, this website, and a bunch of mistakes. So, I have what is probably a pretty basic question for most folks.
 
What is the difference between Firewall Access Rules and ACL/ACE? And when to use which?
 
for example: on my ASA 5520s I've set up an Interface for my internal LAN: 172.16.x.x., a DMZ 192.168.2.0/24, and an interface for the Internet side. The 5520 is set up as a routing firewall betwen my internal lan, DMZ, and Internet.
 
If I want to allow my internal users Internet access for http and https would I use a Firewall Access rule?For most of my rules allowing outbound access from my 172 LAN and DMZ and inbound access to devices in my DMZ can I mostly utilize the Firewall Access Rules?

Cisco Firewall :: 5520 - Efficient Way To Organize ASA Access Rules

Looking at it looks very unappealing and I'm in the process of adding names and descriptions to all the Network Objects.
