Iptables command "translated" Cisco ASA 5540 Ver 9.0(1)

I would like to have these commands on our Firewall to avoid at least several students to use this service. Can someone help me to translate this? It's apparently working great if I will use an Linux box or another firewall compatible with iptables.
Thanks in advance.

Hello,
NMS is probably not the right community to t/s this. You probably want to move this to Security group (Security > Firewalling).
In the meanwhile, i have some details to share for you to check, though i am not a security/ASA expert.
The Dispatch Unit is a process that continually runs on single-core ASAs (models 5505, 5510, 5520, 5540, 5550). The Dispatch Unit takes packets off of the interface driver and passes them to the ASA SoftNP for further processing; it also performs the reverse process.
To determine if the Dispatch Unit process is utilizing the majority of the CPU time, use the command show cpu usage and show process cpu-usage sorted non-zero
show cpu usage (and show cpu usage detail) will show the usage of the ASA CPU cores:
ASA# show cpu usage
CPU utilization for 5 seconds = 0%; 1 minute: 1%; 5 minutes: 0%
show process cpu-usage sorted non-zero will display a sorted list of processes that are using the CPU usage.
In the example below, the Dispatch Unit process has used 50 percent of the CPU for the last 5 seconds:
ASA# show process cpu-usage sorted non-zero
0x0827e731 0xc85c5bf4 50.5% 50.4% 50.3% Dispatch Unit
0x0888d0dc 0xc85b76b4 2.3% 5.3% 5.5% esw_stats
0x090b0155 0xc859ae40 1.5% 0.4% 0.1% ssh
0x0878d2de 0xc85b22c8 0.1% 0.1% 0.1% ARP Thread
0x088c8ad5 0xc85b1268 0.1% 0.1% 0.1% MFIB
0x08cdd5cc 0xc85b4fd0 0.1% 0.1% 0.1% update_cpu_usage
If Dispatch Unit is listed as a top consumer of CPU usage, then use this document to narrow down what might be causing the Dispatch Unit process to be so active.
Most cases of high CPU utilization occur because the Dispatch Unit process is high. Common causes of high utilization include:
Oversubscription
Routing loops
Host with a high number of connections
Excessive system logs
Unequal traffic distribution
More t/s details can be shared by the ASA members from the community.

Trying to use DS 6.2 w/ Cisco ASA 5540 for VPN Auth

Hello all,
I'm trying to connect our Cisco ASA 5540 with LDAP authentication to our DSEE 6.2 directory. The authentication is failing and this line in the debug output from the firewall is really getting to me: "No results returned for iPlanet global password policy".
Their authentication process is two-steps.. It binds with a service account, searches on the "naming attribute" (in our case uid), grabs the DN of the user, and unbinds. With step 2, it binds to the directory with the DN it found when searching, and the password the user supplied. If the second bind is successful, then the firewall lets them on the VPN.
When the firewall binds with the service account, it successfully finds the user's DN and disconnects, so I know my ACI is working correctly there. It just seems to fail when trying to re-bind with the user's DN...
We opened a TAC case with Cisco, and this is their response:
The DN configured on the security appliance to access a Sun directory server must be able to access the default password policy on that server. We recommend using the directory administrator, or a user with directory administrator privileges, as the DN. Alternatively, you can place an ACI on the default password policy.
I refuse to let a poorly written application or appliance bind as cn=Directory Administrator!
I tried putting an ACI on the default password policy located at cn=Password Policy,cn=config , but that doesn't seem to make any difference to the ASA.. My best guess is that it's looking somewhere else for the password policy... did it used to be located elsewhere in iPlanet? Has anyone made this work before with a Cisco ASA?

My network admin and I ended up solving this problem by sheer dumb luck. In the ASA config, you tell it what kind of LDAP server it's connecting to. In one set of docs, it had the available options as microsoft, sun, or generic. In another set of docs, we found that openldap was also an acceptable option.
I'm guessing the ASA is thinking the "sun" option is connecting to the old Netscape Directory Server. Changing the "server type" to openldap made it work immediately. It also does not look like it's trying to look at the LDAP server's password policy now either.

Command in cisco ASA to see security zones

Hi there,
A basic question.
I can't see security level and zone in show interface ip br command.
Is there any command which can be helpful.
Regards,
Yad Singh

Try 'show nameif'
ASA-FW# show nameif
Interface Name Security
GigabitEthernet0/0 outside 0
GigabitEthernet0/1 inside 100
Management0/0 management 100

Cisco ASA 5540 Syslog logging everything

Hello. I am trying to log every connection (Build, deny, etc)
But for some reason I don't see them sh log
Any ideas?
asa1# show run log
logging enable
logging timestamp
logging emblem
logging asdm-buffer-size 512
logging console debugging
logging monitor debugging
logging buffered debugging
logging trap debugging
logging asdm debugging

logging recipient-address ************* level errors
logging recipient-address ********** level errors

Rahul; I fix the problem. I had every logging output enabled (logging console debugging,logging monitor debugging,logging buffered debugging) and the ASA was loosing the abilitity to log. I disable them and now everyhing is logged.
Thanks

ASA 5505 + ASA 5540 static VPN, ssh and rdp problems

Greetings!
I've recentely set up a VPN between Cisco ASA 5540(8.4) ana 5505(8.3).
Everything works fine, but there is a small problem that is really annoying me.
From the inside network behind ASA 5505 I connect via rdp or ssh to a host inside ASA 5540.
Then I minimize ssh and rdp windows and don't use it for ten minutes. But I still use VPN for downloading some files.
Then I open ssh window - the session is inactive, open rdp window - I see a black screen (for 10-15 seconds, and then it shows RDP)
There are no timeouts on ssh or rdp hosts configured, via GRE tunnel it works perfectly without any hangs.
What can I do to get rid of this problem?
Thanks in advance.

Dear Fedor,
You could try adding the following commands to your configuration (on both ASAs) in order to increase the timeout values of the specific TCP sessions:
access-l rdp_ssh permit tcp 1.1.1.0 255.255.255.0 2.2.2.0 255.255.255.0 eq 22
access-l rdp_ssh permit tcp 1.1.1.0 255.255.255.0 2.2.2.0 255.255.255.0 eq 3389
class-map TCP_TIMEOUT
      match access-list rdp_ssh
policy-map global_policy
     class TCP_TIMEOUT
          set connection timeout idle 0:30:00
          set connection timeout half 0:30:00
* Please make sure you define the specific RDP and SSH ports in the ACL and avoid the use of "permit ip any any".
Let me know.
Portu.
Please rate any post you find useful.

L2TP on Cisco ASA 5505, just doesn't work??!

This is pretty urgent, client expects me to have this up by lunch today
So, there is this Cisco ASA 5505 ver 8.4.
Most things work but now I want to setup a vpn connection...
I have done this 2 ways, first by using the "VPN Wizard" in ASDM and then 5 hours later removing everything and configuring from cli.
And it just doesn't work, client (WinXP & Win7) gets "error 792" and sometimes "error 789" (both indicating problem with phase 1, I'm pretty sure of that)
Googling on those gives a few suggestions none works.
All I get in the log on Cisco is the "Error processing payload: Payload ID: 1"
Googling on that only comes up with a few pages telling me this message is caused by an error. (Yeah, I could never have guessed...)
For the cli config, I followed this tutorial carefully (3 times actually...)
http://www.cisco.com/en/US/docs/secu...html#wp1117464
I'm using PSK for IPSec, entered same on Cisco and client - checked several times, this is not a password/PSK issue.
Ports opened on Cisco: 500, 1701, 4500
(For a try I opened all ports, no change.)

Problem Packet Flow through Cisco ASA Firewall

I have a Cisco ASA 5540 8.2(1), with permit ip any any rules
packet-tracer input inside tcp 10.56.149.129 871 10.40.170.10 3003

if you change the source or destination port, the packet is successfully
clear conn did not help
please tell me how to solve the problem?

Hi,
I would suggest sharing the firewall configuration (except for any sensitive information they might have) so troubleshooting this would be easier.
It would seem to me that during your "packet-tracer" test there is already an existing traffic flow through the ASA with the same information that you entered in the command.
I don't know however why the connection would be blocked according to the "packet-tracer". In my own test this seemed to work. Output was otherwise the same but the "connection" wasnt dropped.

Hi Everyone,
                  My Expertise with Cisco ASA is Very less. I have observed Input errors in a Couple of Interfaces in Cisco ASA 5540 Firewall.
296867 input errors, 0 CRC, 0 frame, 296867 overrun, 0 ignored, 0 abort
0 pause input, 0 resume input
0 L2 decode drops
102091138038 packets output, 96596756282996 bytes, 2683 underruns
0 pause output, 0 resume output
0 output errors, 0 collisions, 2 interface resets
0 late collisions, 0 deferred
52 input reset drops, 0 output reset drops, 0 tx hangs
input queue (blocks free curr/low): hardware (255/230)
output queue (blocks free curr/low): hardware (255/0)
I need to Clear the Input errors on this particular Interface.
Will Clear interface GigabitEthernet 0/0 will help?
Thanks in Advance,

Reasons to upgrade cisco ASA

HI
I have two Cisco ASA 5540, these ASA running ver 7.2. and used mainly as VPN gateways.
My question is simple, Apart from the extra AnyConnect client functionality and the higher encryption, is there any specific security benefits (related to the VPN use) for upgrading to ver. 8.x ?
Thanks
A.

Ammar,
Each version has Release Notes. For the ASA they are all posted here.
In each Release Note there is a "Resolved Caveats" sections. That is where the fixes for all problems - vulnerabilities as well as functions/features - are listed.
Besides higher encryption and Anyconnect client, you can also use IKE v2 (as of 8.4(1) ) which is more secure during session setup (apart from the level of encryption). You can also use identity-based features and a host of other features to further secure your remote access VPNs. On the other hand, if what you have now is meeting your needs, the only compelling reasons to upgrade are vulnerability and bug fixes (and perhaps a prettier version of ASDM that will run with the newest Java versions ).

Seeing ASA 5540 with High CPU Utilization

I have a remote site customer with a Cisco ASA 5540 running SSLVPN (Anyconnect)(8.03). It currently only serves about 450 SSLVPN clients. Since last friday, they've seen the CPU utilization go up to high 90% while only serving 400+ remote users. Please help us troubleshoot the root cause of the CPU high utilization on Cisco ASA 5540.

This doc is a good starting point:

Tools use to monitor cisco asa

Hi all,
I just roll out a cisco asa 5540 and use it as a SSL vpn concentrator.
Can i know what tools you use to monitor the cisco ASA, eg account with most number of login attempts, number of fail attempts etc
TIA!

You can look at Cisco Prime Collaboration Assurance if you're willing to upgrade to 10.0; they have started providing a free Standard license. They of course hope to upsell you to Advanced but the goal is for Standard to be an alternative to RTMT. There are also a plethora of ecosystem partners with product offerings in the Developer Marketplace.
Please remember to rate helpful responses and identify helpful or correct answers.

High CPU Utilization on ASA 5540

I have a remote site customer with a Cisco ASA 5540 running SSLVPN (Anyconnect)(8.03). It currently only serves about 450 SSLVPN clients. Since last friday, they've seen the CPU utilization go up to high 90% while only serving 400+ remote users. I saw some high cpu utilization bugs, but none looked to be relevant. Any ideas on how I can find the root cause of the CPU high utilization?

Hi rlortiz,
I ran into this issue as well on an ASA 5540 with only about 150 users. In the case if you are using large modulus operations including large key size certificates and a higher Diffie-Hellman group, it will cause for high processing.
Since the default method of processing these operations is software-based, it will cause higher CPU usage and also slower SSL/IPsec connection establishment.
If this is the scenario for you, use hardware-based processing by using the following configuration:
"crypto engine large-mod-accel"

Command to View LDAP Password on Cisco ASA 5520

Hello
I am migrating from a Cisco ASA 5520 (ASA version 8.4(6)5 to a Cisco ASA 5585. We have LDAP issues logging into to our vpn client software. I assume the LDAP password may be incorrectly entered on the new 5585. No service password- encryption or more running:config won't show the encrypted LDAP password. What is the command to view that?
Thanks!
Matt

Thankyou Jennifer for the responds.
Could you please help me on how to enable "memberOf" attribute on AD to be pushed to ASA for the OU matching.
i have already set the "Remote Dialin" property of user account name "testvendor" in AD as "Allow Access" .It can be shown in the debug output as below.
[454095] sAMAccountName: value = testvendor
[454095] sAMAccountType: value = 805306368
[454095] userPrincipalName: value = [email protected]
[454095] objectCategory: value = CN=Person,CN=Schema,CN=Configuration,DC=abc,DC=local
[454095] msNPAllowDialin: value = TRUE

[454095] dSCorePropagationData: value = 16010101000417.0Z
Is their any other settings that i need to do it on AD ?
Kindly advice
