View 1 RepliesI'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) ?

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.

View 6 Replies View RelatedI try to get a ASA with the new software 8.4.2 running. On an old pix we had the nat command: static (inside,outside) tcp interface www 192.168.15.252 www netmask 255.255.255.255 0 0,In all the new documents about 8.4.2 I can find that it should work with something like:
object network web_host nat (inside,outside) static interface service tcp www www
I want to forward http traffic from the outside interface to this host. In the log I just get entries about blocking ACL - but both is allowed on the outside access-list - traffic to the inside IP and also to the outside interface IP.
I also tried it with "Public Server" - but when I try to use the Interface address I just get the message: Address x.x.x.x overlaps with outside interface address.
Is it still possible to do port forwarding on the outside interface?

What I want to do is allow our support team to perform ALL show commands (up to and including show run) but not enable them to perform ANY configuration changes on the devices (not get into config t). This is to allow them to check ARP tables, routing protocol status, etc
i don't have access to the ASA at the moment and haven't been able to figure it out in IOS, i'm assuming its not too hard.
I want to know with an ASA 5505 w/ Security Plus License I get up to 20 VLANS/Named Interfaces.I have a customer that is getting a new subnet of external IP addresses from their service provider and a different default gateway to accomodate re-hosting their datacenter at their main office instead of at a Colo. My question, when building out their new DMZ, can I have multiple route 0.0.0.0 commands?
Example.
Current Default Gateway 1.1.1.X
Internal hosts 192.168.1.0 use and are natted to 1.1.1.X
New Default Gateway for DMZ Servers 2.2.2.x
Internal hosts still use 1.1.1.X, but server hosts in 192.168.1.3 should use 2.2.2.X -- there are also a bunch of pre-existing static NAT rules for these servers such as 2.2.2.30 translates to 192.168.1.30.
I think I would accomplish this by using the following:
route inside 0.0.0.0 0.0.0.0 1.1.1.X
route DMZ 0.0.0.0 0.0.0.0 2.2.2.x
Would this be correct?
I have a Cisco 2811 router and i want to experiment on the IOS firewall.The thing is, none of the commands that are proposed in online guides - like ip inspect, ip audit, etc. - seem to be working. I just get "unrecognized command" on a router that is supposed to support such features. I'm wondering if it has something to do with the IOS image.

[code] As you can see I have set the ASDM and console to the same level. Currently in the ASDM I can see a user getting denied access to a device, but in the console view I dont get that, which I woudl like.

Administratration | Firewall | Firewall Logs, I can select any or all items. Where do I view the log?
I can go to Logging | Logging Policies and select everything for the 'default' policy.
No matter what, I go to Status | View Logs, and select whatever severity level I want but get little to nothing, and definitely no firewall logging.
One of our client has a Cisco IOS router 2851 with Zone Based Firewalls, enabled.
We tried to configure the router to receive the logs and we receive it in the following format:
<189>45: *Apr 11 11:22:14.757: %SYS-5-CONFIG_I: Configured from console by vty0 (10.151.xxx.xxx)<190>46: *Apr 11 11:23:13.109: %FW-6-DROP_PKT: Dropping tcp session 10.151.xxx.xxx:1908 212.58.xxx.xxx:80 due to RST inside current window with ip ident 0<189>47: *Apr 11 11:38:02: %SYS-5-CONFIG_I: Configured from console by vty0 (10.151.xxx.xxx)<190>48: *Apr 11 11:40:57: %FW-6-DROP_PKT: Dropping tcp session 10.151.xxx.xxx:2062 74.115.xxx.xxx:80 on zone-pair Outbound class CMAP_Inspect_Out due to Stray Segment with ip ident 0
However, we support the following format:

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?
I use ASA 5510 and I would like to log VPN traffic ( for example, as soon as a remote user try to connect to the asa). I would like this log be send to a specific mail address. I already configure Email Logging for severity ( level 3) and it works well.
How I can add the VPN traffic Log ?
I have configured dhcpd in an ASA 5505 and every thing is working. I am testing it to give me a warning when the address pool is about to be finished or it is empty. But don't konw how to do it. if I run the "debug dhcpd packet", i get that the address pool is empty.

When I make a change at the CLI, syslog message ASA-5-111008 is generated and sent to the syslog servers, local buffer, and ASDM.When I make a change in ASDM, syslog message ASA-5-111008 is generated and sent to the local buffer and ASDM. It is NOT sent to the syslog server.

Is it possible to configure the ASA to:
log syslog informational to one host
and
log syslog critical to a different host
It seems that the ASA allows you to only specify 1 logging severity level for all syslog hosts..

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).
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?
on ASA 5540 , i configured the logging setup as following :
log in to the internal buffer : buffer size 1048576 bytes
Then i save the buffer to FTP server to save the log messages in continuously way everything was working fine but suddenly sending the ftp traffic to FTP traffic has stopped suddenly before in the live log viewer it was showing when ASA throws the ftp traffic to the ftp server but this stopped suddenly nothing has changed in the ftp server setting (same username and password and the connectivity is there) sending logging traffic to the ftp server came back just when i reboot the ASA.but this is not solution.
We were using ASA-5520-K9 with ASA-SSM-AIP-20-K9 but recently found some hardware problem in our running ASA. Now cisco want to replace with ASA-5520-K8.
