Cisco Firewall :: Asa5510 Idle TCP Connection Timeout With Flags
May 14, 2012I have ASA 5510 with 8.2.4 and 8.0.x OS and all seem to have common problem of idle TCP connections not timing out. The host to host connections are coming over VPN tunnels. I have default timeouts on all the firewalls. I have tried changing global timeouts and as well as host specific timeouts using MPF but doesn't work at all ! The problem is when TCP connections are sitting idle in conn table for days and when connection limit of 50,000 conns reach the firewall starts behaving unpredictably dropping packets or unresponsive! I need the unused idle connections to timeout which is NOT happening either by changing global values or MPF.

Oct 30, 2012Modem is a Netgear dgn2200
On the modem page with all the settings Under basic settings For connection it says Always Connected The box underneath says idle timeout 5 (that's in minutes)
I am unable to change that number or even get a cursor to appear in that box (I want to change it to a 0 - my internet connection has been dropping out when going idle). I can't right click or anything. That is using Firefox. When I say dropping out, I mean, the 3 computers on the network become unuseable - nothing works and things don't appear to be connected to the internet even though my green ADSL light stays on like it's connected - it is not.
I tried the same modem page in IE, and that box with the 5 in it is still showing 5, but this time it's just grayed out - again, can't be changed. The firmware updates are all upto date (apparently - according to it's check)

Cisco Wireless :: WLC 5508 Controller Idle Timeout Limit
Dec 20, 2011The behavior of some mobile devices ( as Iphone , Itouch, not Blackberry, not labtops ) with WL Controller (5508) is that, when the client doesn't use it, it disconnects after 480 sec.

Why the behavior is different in this type of devices? Increase the idle timeout is a solution?
Cisco Application :: CSS 11503 Flow Idle Timeout Not Working As Expected?
Jan 20, 2012I have a CSS 11503 with a basic content rule for TCP 10000 going to a few backend servers. I was looking into the default timeout values for flows and when testing using telnet the flow didn't terminate as expected?
For example, i have no 'timeout multiplier' specified in the config and when i look at the output of 'show flow-timeout default' it tells me the default 16 seconds timeout is in effect for *. With that in mind, i telnet to the content rule vip on TCP 10000 and on the backend server using wireshark i can see the TCP threeway handshake. With no data passing i'd expect the CSS to terminate this flow after 16 seconds.. yet it takes exactly 128 seconds before wireshark shows the RST and the flow is terminated. 128 being 8 times the default 16 second flow timeout.
If i try to force the connection to close early by specifiying 'flow-timeout-multiplier 2' in the content rule, or even a multiplier of 40, it still waits 128 seconds to close the telnet connection.
Cisco Switches :: SG300-20 - Radius Idle And Session Timeout Does Not Work
Jan 25, 2012I have an SG300-20 here for testing (firmware: 1.1.2.0, boot version: 1.0.0.4, language version: 1.1.1.6 English). Everything seems to work on it, except, that if I choose Radius authentication by mac address only, then the switch does not honor the Idle-Timeout and Session-Timeout attributes from the Radius server (freeradius).
The setup is the following: I have a no name access point plugged in to switch port gi1. The port gi1 is set up for Radius authentication by mac address only. The access point itself is authenticated, no problem with that. If I connect through the access point by (say) a mobile phone, it is authenticated, no problem. The radius server does send the Idle-Timeout and Session-Timeout attributes, I checked it by running "freeradius -X", both are set to 30 seconds. Then I turn off the wireless card in my mobile phone and check the dot1x users by "show dot1x users". My mobile phone's mac address remains there for 5-10 minutes, so the Idle-Timeout and Session-Timeout does not work.
Another way I could resolv this problem is by explicitely asking the switch to reauthenticate the user. Unfortunately there is no CLI command to do just that, I can do however a reauthentication on a port using "dot1x re-authenticate gi1" (for example). But it does not work as it is expected: the switch uses the stored mac-address to reauthenticate the user, so nothing changes on the port (unless something changes in the radius server). I think it should work like the following: remove the authenticated user from the port, and whenever that mac address makes some network traffic, then reauthenticate as if it were a completely new connection. BTW: it would work for me also if I could just remove an authenticated user from a port, but I did not find a command to do that.
As a last resort I can simply shutdown the port, bring it up again ("shutdown" and "no shutdown" in the interface config), then all users are removed from the port and they all mush reauthenticate. But it causes a network outage for a couple of seconds for all users on that port, on a busy access point it is quite disturbing, and it is not an elegant way to do this.
So my actual question is: is there a way to remove an authenticated user either automatically (Idle-Timeout and Session-Timeout) or manually from this switch?
I enclose the relevant part of the running config.
interface range gi1-2
dot1x host-mode multi-sessions
exit
vlan database
vlan 2-4
exit

Cisco VPN :: Verify NAT On ASA 5510 Working?
Aug 16, 2011I'm working on setting up a site-to-site VPN connection that requires us to NAT an internal address. Typically, this would be no big deal, but for some reason, it's not working for us. The remote site is reporting that they are seeing the original IP address and not the mapped address coming across. I've monitored the connection and base on our ASA logs, I too see the un-mapped address.
Is there a quick and easy way of verifying that NAT is working? Logs, etc.?
Unfortunately I don't currently have the remote side's configuration, as they are an external business, but I can provide ours: [code]
Based on the above, it sounds as if our configs aren't jibing, which I would think could be caused by the NAT configuration not working, right? I mean if the VPN applicance on the remote end is expecting a NAT-ed address of 12.131.67.247 and they are receiving 12.10.127.108, that could cause this issue, couldn't it?

Oct 31, 2011We have an ASA 5510 that handles our vpn client traffic, and occasionally, we run into a client that, while using Cisco AnyConnect in conjunction with Phonefactor, the connection attempt will timeout before the connection actually establishes.The odd thing is - The logs show the client finished connecting, and the Phonefactor server shows completed authentication. We even added a custom timeout script to increase the default 12 second timeout to 30 seconds.This behavior has proven difficult to find a common factor for, as it has affected different versions of the client, 2.3 and 2.5, as well as Windows XP, Vista and 7 installs. This problem does not affect our Anyconnect/RSA clients, and if the same person on the same client with the issue is migrated over to the Cisco IPSec vpn, the problem disappears.

Feb 16, 2012I am looking for the way to define an idle timeout for specific flows on an ASA5580 by using Cisco security manager. For ex I needed to define a specific idle timeout for connections beetween specific devices (Devices in vlan1, Device2 in vlan2).To test it I did following changes by CLI and it works fine. access-list L1 extended permit ip <@IP1> <mask1> host <@IP2> class-map CM1 match access-list L1 policy-map PM1 class CM1 set connection timeout idle 02:00:00
I try do do the same configuration with CSM in order to be able to manage each changes only by using CSM.So I defined Access control list, Traffic flow and then I define timeout in CSM --> PIX/ASA/FWSM Platform --> Service Policy Rules --> IPS, QoS and Connections Rules -> connections settings -> Traffic flow idle time-out. The problem is that each time I deploy the configuration with CSM I loose the timeout config line which is the most important for my application..

Cisco Firewall :: ASA 8.4.1 SSH Timeout Vulnerability?
Feb 20, 2013Faced this recent vulnerability?
[URL]
My understanding is that for ASA 8.4.1 and prior, there's a vulnerability that opening many ssh sessions and one of them times out, the firewalls crashes!
As we have many customers with ASA using 8.2.5(26) (for example) I'd like a confirmation that for fixing that bug I need to upgrade my ASA image to at least 8.4.x.Case that, I believe that all the former firewall configuration must be reviewed because 8.2.x version has many different commands that 8.4.x (for example, NAT)
Cisco Firewall :: ASA 5520 RDP Session Timeout?
Jun 4, 2012I have inherited the support of an ASA5520 running 8.0(3)12 code and I believe I have a pretty simple question here that I haven't been able to figure out on my own. I have a few users that connect to the box via IPSEC VPN client connections. They want to be able to leave up a RDP based connection, for monitoring purposes, for a most of the day, but thier RDP connection keeps getting discounnted after a few hours. The VPN connection never gets disconnected, just the RDP session running through it. I have another box running 8.0(4) code and they can leave up the RDP sessions as long as they like without getting disconnected from the server(s). I have compared the configs of both boxes and don't see any glsring differences in regards to the configuration that would cuase the RDP sessions to either to stay up or be disconnected after an inactivity type scenario.
What to look for in regards to identifying the timer that is disconnecting the RDP session after a period of time.
Cisco Firewall :: Static NAT SYN Timeout - ASA 5505
Aug 30, 2011I have a 5505 for a small business that has one web server. The web server has a static NAT entry to an IP address and not an interface. There is an access rule allowing any HTTP traffic to the outside IP of the web server. From the web server I can't access the Internet.
All other computers on the network can access the Internet using a dynamic nat rule that uses the outside interface. The web server is accessible from a computer behind the firewall.
If I delete the static NAT entry for the web server I can get on the Internet.
I have turned debugging on and see that an outbound connection is built and then 30 seconds later the connection is torn down with the bytes 0 SYN Timeout message.
I am running 8.0(5).
Cisco Firewall :: Connection Timeout ASA 5520?
Oct 25, 2011I configured multiple vlan on my Cisco ASA5520. Everything work perfectly except RDP (3389) connections. The connections are established but but after a period of inactivity, the user is disconnected from server (black screen).

There's a notion of inter vlan timeout connection ?

Cisco Firewall :: Tcp Flags And Timeout On ASA55XX 8.4(3)
Oct 18, 2012I would like to understand someting about the behaviour of ASA with our traffic scenario and the management of tcp sessions.
1) In particular we noticed that we have connections with the flags Fin without any acknowledgement. The session is silent (the bytes counters aren't incremented) but it remains in the session table as an established connection with the idle timeout of an established conn.
We have about 20% (60K on 300K total) of conns in this state: at our eyes it seems to be an incorrect behaviour...
TCP OUTSIDE 62.149.128.151:110 INSIDE 10.254.158.12:61527, idle 0:11:36, bytes 433, flags UFIO
TCP OUTSIDE 17.151.0.200:443 INSIDE 10.254.229.94:52367, idle 0:01:25, bytes 4597, flags UfIO
TCP OUTSIDE 184.169.79.33:443 INSIDE 10.255.249.146:60143, idle 0:10:39, bytes 5590, flags UFIO
TCP OUTSIDE 157.55.235.158:80 INSIDE 10.170.37.102:62421, idle 0:00:53, bytes 1770, flags UfIO
2) On the connections considered as half -closed we have received an ack to the fin (r or R flag is present), we would like to set the idle timeout to a value lower than 5 minutes but we were not able to reach that result
timeout pat-xlate 0:00:30
timeout conn 0:10:00 half-closed 0:05:00 udp 0:02:00 icmp 0:00:02
!
access-list timeoutClass extended permit tcp any any eq www
access-list timeoutClass extended permit tcp any any eq 8080
class-map timeoutClass
match access-list timeoutClass
class timeoutClass
3) And this type of conns with a Fin on both side that I'm not able to understand... with an ack on one of the side how can I have the other fin??
TCP OUTSIDE 69.171.247.38:443 INSIDE 10.168.139.244:51236, idle 0:11:28, bytes 10536, flags UfFIO

Cisco Firewall :: ASA 60 Minute Inactivity Timeout?
Feb 15, 2013We had an issue the other day where doing backups through the firewall (don't ask) caused the "control" session to timeout while the backups were still going on over the "data" connection. This broke the backup about two hours into the job. My first thought was that the backup solution vendor should implement some kind of tcp keepalive for the control connection. A packet capture showed they indeed were -- after 2 hours! Ah ha! Busted! How could they choose such a poor choice of TCP keepalive timer for their application that would not be compatible with the 60 minute inactivity timer that so many firewall vendors use (Cisco, Juniper, Checkpoint and Fortinet all use a default 60 minute inactivity timer for TCP)?
Well, a colleague of mine pointed out that there is actually an old RFC that covers this. RFC 1122. It says:
Keep-alive packets MUST only be sent when no data or acknowledgement packets have been received for the connection within an interval. This interval MUST be configurable and MUST default to no less than two hours.
Now I know that RFC is old (October 1989), but that's all I could find. Is there something that supercedes that? Maybe common sense perhaps? I understand not wanting to fill up your connection table because of mis-behaving applications, but I'm just looking for ammunition to use against the backup solution vendor. Surely they're going to point to this RFC.

Cisco Firewall :: PIX515 - Timeout ICMP / Access Lists?
Mar 29, 2011I am using a Pix 515 with IOS 8.0(3).I have in my access list on the outside interface.......access-list outside_access_in extended permit icmp any 12.23.34.0 255.255.255.0 echo access-list outside_access_in extended permit icmp any 12.23.34.0 255.255.255.0 echo-reply.......in order to allow ping requests and ping replies into my inside network. This certainly works since I can ping the inside from outside and vice versa, but in the ASDM display of access rules, the hit count for these two lines is always zero. If I run 'show access-list', the hit count for these lines is non-zero.
Why doesn't the hit count show up in the ASDM gui display?Also, I have read that the PIX does not treat ICMP in the same way as TCP or UDP and there is no stateful behaviour towards ICMP. However, if I set up a continuous ping from outside to inside and then disable the above access list rule allowing echo requests towards the inside, the ping continues whereas I would expect it to stop.
In the config there is 'timeout icmp 00:00:02' if there is no stateful connection for ICMP, why is there a timeout value for it?
