• IOS Firewall feature set and slow down access HTTP...

  Recently turned on the firewall, on a router, and often feature some

  Web sites are rather slow. I tweaked the ip inspect max-incomplete and

  one - minutes, but the problem persists - deletion of IP inspect and these

  command solves the problem.

  ANY ideas on how to fix?

  Sincerely,

  Daniel Melameth

  You inspect http traffic in particular? If Yes, I would like to remove this and just inspect other protocols and tcp and udp in general. Inspection of http is really useful if you want to stop the Java applets arrive, which to be honest, that almost person does. If you do not have something like this, remove the inspection of http as it slow down considerably.

  That said, 12.2 (8) T has had a lot of performance improvements put into it for the CBAC specifically, you can also try the upgrade than or later to see if it solves the problem also. See http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122t/122t8/ftfirewl.htm

• Cannot trace to the hosts on the international research reports using FW feature set

  The problem is that we can draw between facilities network on tunnels involving ISR routers using the firewall feature set, but we cannot trace the guests. Example of AS1 (US), I can trace to 192.168.1.2 (UK) CS1 the ip address, but not to host that I found in the arp table for this vlan. I added exceeded ICMP TTL and TTL timeouts for the ACL, but it still does not work.  Any helf would be greatly appreciated

  Elijay, you have said that you don't use a SRI you may be running inspection? If so, you can check your ICMP rules for router-traffic and delays. You can increase the time-out setting.

• How to uninstall all firewalled and set up a new

  How safley uninstall a firewall and set up a new one?

  Hi JackieLynn

   

  1. what operating system is installed on the computer?
  2. don't you want to uninstall Windows Firewall?
  3. you have any third-party firewall installed on the computer?

  Do check and provide us with the information about the installed operating system-

  http://Windows.Microsoft.com/en-us/Windows7/help/which-version-of-the-Windows-operating-system-am-i-running

   

  In Windows 7, you cannot uninstall a firewall, you can simply enable the firewall MARKET (if you wish). Just please refer to the article below and use the steps provided to disable the firewall or ON -.

  WARNING:

  You should not turn off Windows Firewall unless you have another firewall is enabled. Turning off Windows Firewall may make your computer (and your network, if you have one) more vulnerable to damage caused by worms or hackers.

   

  I hope this helps.

• IOS Firewall

  Hello

  What devices can I find ios firewall services, ZBF and url filtering? is it only the routers or there are PIX too?

  Thank you

  PIX and ASA devices support ZBF, URL filtering and firewall services. However almost all high mid-range to routers have firewall/ios function (Cisco3640 router with firewall IOS version 12.2 media services), SRI series routers support ZBF and URL filtering.

• 1721 router + 4esw, WIC + IOS firewall

  Hello

  I have a router (192.168.157.254) Cisco 1721 with a 4port10/100 wic installed.

  Is it possible to filter using IOS Firewall if wic address and lan are similar? I know it's that they have different ip addresses is possible, but if they are in the same LAN?

  For example:

  A server (192.168.157.10) connected directly to the router FILTER wic and using the LAN interface.

  Is possible?

  Best regards

  Yes, the IOS Firewall can filter even if the address LAN and wic are similar. The following link can help you

• Request for suspension after deployment iOS Simulator

  Hello
  
  If a deployed application of JDeveloper for the iOS Simulator is 'suspended' just after the Simulator presents itself (no content displayed - only a symbol of the wait, blocked Device Simulator), this behavior have trigger known causes? If so, who are? Has anyone experienced this problem as well?

  If you have enabled java debugging by setting java.debug.enabled = true in cvm.properties. I fell on the same subject. As soon as your application starts, it waits for the remote debugger to connect and appears to hang. It's a warning in section 17.3.3, but I think that a lot of people will continue in this issue.

  It would be better if the rotation animation could be replaced by a message saying that it has to wait for a remote debugger to connect. Maybe a nice improvement ask :-)

• Multi-tenant IOS Firewall and security even subinterfaces 9.0

  Hi all

  I'm so used to< 8.3="" and="" am="" having="" great="" difficulty="" getting="" an="" environment="" working="" properly="" so="" i'm="" now="" going="" to="" leverage="" the="" cisco="">

  We set up a network with clients behind a pair of 5510 s.  All of these clients will have their own dedicated sous-interface in their own VLAN.  Out the door, I got inter - allowed security-same interface and all networks communicate with each other.  I certainly don't want that, so I have disabled this command and now each network client is unable to communicate with each other, as expected.

  The problem now lies in networks where a customer have 2 VLANS separated (say a staging and a prod environment) where they need to communicate.  Is it feasible if they are of the same security level and even security allowed inter-interface is disabled?  I just need to create an ACL for the networks to talk?  Is there a better way to do this with the same security allowed active inter-interface?

  8.3 pre, I have same security allowed active inter-interface, but traffic could not speak to the other interface unless I created an exemption NAT and ACLs.  Always create a NAT exemption?

  Hello

  The basic problem that you run with different software levels is the parameter 'nat-control' that exists in 8.2 (or earlier version), but does not exist in version 8.3 (or subsequent version of the Software ASA).

  In the 8.2 and pre software you got with the nat configuration change 'control' of requiring a connection to have a NAT configuration to be able to pass traffic through the ASA. Of course this coupled with the 'security level' gave you more changes to control traffic without resorting to the ACL.

  However, in the new software of 8.3 and later the "nat-control" level no longer exists and that a connection has a NAT configuration that be applied or not ASA still allows the connection (subject other ASA controls allow) so basically you won't need NAT configurations between your local interface. The most common NAT configurations should be between your local interface and the "external" ASA interface.

  If you try to control traffic between interfaces with the global configuration commands you mention, you will eventually be 'juggling' with the 'security level' configurations autour constantly so that the correct rules for traffic is applied.

  This question came up on these forums every now and then, and I almost always offer the same approach which is to set up an ACL on EACH interface of the ASA.

  • Remember to leave the 'same-security-traffic"on the SAA configurations. It is because even if you have interface ACL allowing traffic, if they are for some reason any left with identical "security level"custom ACL be sufficient to allow the traffic. "
  • Configure each interface an ACL
  • Initially to configure the ACL to create a "object-group" that will contain EACH network behind your local interface of firewall (except the "outside" ofcourse)
  • Use this category 'object' at THE start of ACL interface to BLOCK ALL traffic behind this interface to these networks
  • After that allow or block different/Out Internet - linked as usual traffic
  • In the same networks 2 (or more) behind the need of different interfaces to communicate with each other, set up a statement that allows early each ACL. The already existing 'decline' exposed with the 'object' group already will ensure that other traffic between networks are blocked

  A very simple example, you might want to consider the following

  Networks:

  • LAN1: 10.10.10.0/24
  • LAN2: 10.10.20.0/24
  • DMZ1: 192.168.100.0/24
  • DMZ2: 192.168.200.0/24

  access-list IN LAN1 ip 10.10.10.0 allow 255.255.255.0 any

  LAN1-IN group access to the LAN1 interface

  And of course all other ACL would follow the same model in one form or another. You would really have to worry about traffic is allowed between interfaces, but rather the most work would probably add "allowed" in the upper part of each ACL when required for communication inter-interface. But I guess that the amount of these additions would remain also to a manageable level for FW admins.

  Naturally in environments the biggest you would probably get a high-end ASA and virtualize it and separate each customer environment in their own security context where you would avoid this situation together. Naturally the biggest points against this solution usually can be fresh and the fact that virtualize the ASA multiple context mode disables some essential operational capability of the SAA, which the most important is probably the Client VPN connections (VPN L2L is supported in the software in multiple context Mode 9.x)

  Hope this helps

• IOS Firewall (CBAC) + Path MTU Discovery

  I was reading just through the 12.2 T documentation CBAC and saw the section on the icmp inspection and how he wildcards outside IP because no matter what a leap could return it with the responses of time exceeded and inaccessible destination.

  See that made me wonder if this was true for TCP as well, especially in situations that involve Path MTU Discovery. If an internal system initiates an outgoing TCP connection that is inspected by the FW IOS, an external host responds with an ICMP Fragmentation needed but DF Bit set to message, the router will consider this part of the session and send it to the host internal?

  Thanks in advance.

  -Mason

  Mason,

  ICMP by CBAC inspection does not include packets 'package-too-great. Therefore, you must explicitly allow these packages in your ACL for PMTUD to work that the router would not consider these packages to be part of the TCP session and drop them.

  See the link below for the types of ICMP packets supported by CBAC.

• Issue of Logging IOS Cisco features

  -Want to know if the logging of Cisco IOS is substantially the same as logging on firewalls?

  -For example, we have a few VPN concentrators and want to turn on logging in such a way so that we can see that attributed to the users IP address and username, MAC, computer name if possible, when users connect remotely.  Is it possible on Cisco VPN concentrators as 7301, 3640, no. 2851

  -Also would like to be able to connect the ACL logs.

• Cannot use the feature set in windows media player for Onkyo TX - NR509 Receiver Media

  I have the Onkyo TX-NR509 and everything works fine except for streaming music from windows media player. (I can sink my iPhone to the receiver box and can even navigate to my music box cylinder head and all the Games very well).

  When I click with the right button on a song and select "play to" and then select the amplifier box "play to" appears and after a while an error message appears "cannot retrieve information about the UPnP Server media."

  My laptop is a HP Pavilion dv7 (Windows7 64-bit)

  I made a few simple troubleshooting;

  1. under Network TX-NR509 shows as a support device and I installed the drivers.

  2. I checked the options of streaming media and my receiver is set to "allowed".

  3. in WMP, I did of course "allow the remote control of my player" and "automatically allow devices to read my media" are both checked

  4 reboot the router & mobile.

  I have no idea what could be the cause and to say it's frustrating is an understatement.

  I'd appreciate any help you could offer.

  M4A http://support.Microsoft.com/kb/316992 is not supported. You can try
  copying a file and rename it to mp3 to see if it works, but probably not.
  you will most likely need convert files to mp3 format.

• IOS Firewall between network internal

  Does anyone have an example of configuration or a guideline for the implementation of a standard firewall between a group internal?

  The scenario is a 3640, with only 2 network interfaces to provide a firewall for a small network with only 3 customers on this subject who need access to internal LAN of business for an application only.

  I have loads of info on all other types of scenario, but not one like this where no internet access is required or used and 2 networks are connected by frame relay or ISDN.

  Any help would be greatly appreciated.

  Claiming that only TCP applications are used and a specific web server. In addition, this example assumes that the 3640 is at the remote site. If the other access is desired you will need to check other protocols. Don't forget that you will need directions on the local and remote router to the appropriate subnets. For security, it would also make sense to limit

  inspect the name fw tcp IP

  interface ethernet0/0

  customer group-access IP in

  interface serial0/0

  IP inspect fw in

  customer IP extended access list

  allow any host 192.168.1.2 eq 80

• IOS firewall/Internet on DSL (PPPoE)

  I have a Cisco 2651XM laying around and I want to implement a NAT (inside) firewall and the external interface to dial a number using PPPoE (it would be connected to t a DSL modem). How can I do this?

  Thank you!

  Also, make sure that your user name and the password that you use for pap authentication are correct. It won't hurt delete this statement and configure it again just to make sure that you did not a character during the first extra space that you inadvertently configured.

• Improvement of the feature: set the timing of mouse separated from slide

  We need the ability to adjust the timing of mouse separately by the timing. For example: I want to have the visible slide for 15 seconds. I want the mouse appear immediately (when the slide appears 0.0 seconds). So, I want the mouse to 'travel' to about 2.5 seconds. However, when I save the file and look at the slide, Captivate allows you to set the mouse appear 0.0 seconds after the slide appears, but now the mouse takes 15 seconds to 'trip '. When the distance between objects on the screen is light, the mouse movement is almost imperceptible.
  
  Thanks, DBlake

  Unfortunately, the function of the chronology and the functionality of the properties for the mouse seem to work differently. I continued to change the properties of the mouse and setting the properties of the slide. Then when I went to another slide and came back, I noticed that Captivate automatically changed the properties of the mouse in order to integrate the length of time of the slide. However, using the method of drag timeline seems to solve the problem. I am happy to know that we can solve the problem, but I think we can have a bug on our hands.

  I'll be passing the method timeline along as the solution for our team. Thank you for all your help. -DBlake
