• Redundancy for transparent firewall IOS

  One way to implement redundancy in IOS (12.3.7.T) transparent firewall?

  If this isn't the case, is that it works with PIX 7.0 with failover?

  Thank you

  No and no. No mechanism for failover in FW IOS and two code bases are independent of each other so that they work together as a failover pair. You will need two PIX to failover.

  I hope this helps.

• IOS transparent firewall

  Hello

  I am trying to configure transparent firewall IOS on a box of 2600 with IOS 12.4 (1), following the guide available.

  FastEthernet 0/0 - internal IP address 10.0.0.1

  FastEthernet 0/1 - external, no IP address

  Both belong to the same bridge Group 1, and 'show the bridge group' shows that they both be "transmission".

  A laptop is attached to the external interface for the test (with the LAN IP address), and I can ping the box from Cisco if I add an IP address to the external interface.

  However, bypass surgery doesn't seem to work. I am trying to ping address of the laptop and I see no replies to ARP requests. 'the bridge' displays of the router knows the MAC of the laptop, but didn't bother to respond to ARP requests. Any ideas?

  I apply no access list for now, until I do Bridge works.

  Thank you

  I've never set it before, but read a doc about it shows this:

  From:

  http://www.Cisco.com/en/us/products/SW/iosswrel/ps5207/products_feature_guide09186a00801ee193.html

  BVI system requirements

  If a BVI is not configured, you must disable the Routing IP (via the no ip Routing command) for the transition operation is taken into account.

  If configured, a BVI must be configured with an IP address on the same subnet.

  You must configure a BVI if more than two interfaces are placed in a bridge group.

  The doc, it seems you must use a BVI-config and not put an IP address on the FastEthernet interface if you have a router functionality as well into the bridge group.

• Datacopy ASO to OSI other than a transparent partition mode

  Dear,

  I'm stuck in one of the strange question.

  I copy data from ASO to BSO, data stored in OSB and then perform the conversion of currencies in OSB.

  If I use the transparent wall, data will not be stored in OSB and then all other scripts will not work.

  Please can anyone suggest me how to achieve this.

  Even the Xref and XWrite are also not supported in ASO.

  Hello

  Exactly... Good to know it works now.

  Do you know why he needs the IP address (such as a transparent firewall)?

  The ASA will act as a transparent layer 2 on the right device to the network, but what happens when the ASA does not have a particular destination mac address... What would be the source ip address of the package? Ip address of the ASA. So that's the main reason why we need that.

  We use it also for traffic management and for AAA services (if authentication is used the ASA will send the AAA authentication request to the server) with the IP address of this source.

  Please check the question as answered, so future users can pull of this

• transparent mode with AIP-SSM-20

  I currently have an ASA5510 routed with AIP-SSM-20 mode.

  It is necessary to use a connection in optical fiber between the ASA and ASA on the campus, so the AIP - SSM will need to be removed and replaced by the SSM - 4GE.  This section should present no problems.

  However, this will remove the IPS device, and I always want to use IPS.

  So what I think is to get another ASA5510, install the AIP - SSM, configure ASA for transparent and put it between the inside of the ASA routed and my local network.  The ASA transparent would be strictly works in the form of an IPS appliance.

  The installation program should look like this:

  Internal LAN <> ASA transparent with IPS <> routed ASA <> WAN

  The AIP - SSM can always perform with the ASA in transparent mode IPS?

  Is it possible to configure the ASA and AIP - SSM such as traffic to and from a particular server completely ignores the AIP - SSM?

  I have a couple of file servers which generate heavy traffic and can overload the AIP - SSM.

  Kind regards.

  AFAIR, it is no installation AIP in a transparent firewall problem.

  "The SAA in transparent mode can execute an agreement in principle.  In the event that the AIP fails,

  the IPS will fail-open and the ASA will continue to pass traffic.
  
  However, if an interface or cable fails, then traffic will stop.  You
  
  would need a failover pair to account for this failure event, which
  
  means another ASA and matching AIP."
  
  

  And no there is no problem to exclude certain hosts/ports/subnets inspection by IPS via MPF.

  http://www.Cisco.com/en/us/docs/security/ASA/asa82/configuration/guide/IPS.html#wp1050744

  What I consider however is however if the ASA 5510 as second level firewall for 5520 s will be enough.

• ASA 5505 Firewall Transparent with a Server Web Question

  I need to replace my Sonicwall firewall and I got an ASA 5505. However, I need to have a transparent firewall, no Natting and Server Web will have a public IP with relevant ports remains open.

  The simple illustration is the Internet---> firewall Transparent - Web Server (With public IP Address)

  1. There should be no natting

  2. the web server must have a public IP address and be accessible from the internet.

  3 ports can be blocked or re-opened.

  Please let me know if its possible to conclude this agreement.

  If so, can I get a command line sequence that allows this work.

• As a transparent (bypass) PIX firewall?

  I'm doing a school project that involves the use of a firewall PIX between the ISP and the edge of the network router. The goal is to make the network as secure as possible using only the PIX. Ideally, I'd like that it if an attacker could not even see the PIX was there. It made me think if the PIX can act as a transparent firewall, otherwise said, not having all the IPS assigned to the interfaces nor do no routing, simply inspect/forward traffic between inside/outside interface. Otherwise, I'll have to create a small 30 between the ISP and the PIX from the outside, and the border router and the route PIX inside and between them.

  If I do the latter, can you give me advice on how to secure more PIX? Here is my config:

  interface ethernet0 10full

  The PIX can now act as a layer 2 firewall, this feature will be in the next major version of the code should be out later this year. For now you will need a small subnet between the ISP and the PIX.

  If you do not want to see the PIX then the first thing is to make sure it does not meet the pings. Use the "icmp" command (http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_sw/v_63/cmdref/gl.htm#wp1026574) for. Make sure you allow ICMP unreachable to the outside interface well and Path MTU Discovery can work properly (http://www.cisco.com/warp/public/105/38.shtml#pmtud_fail).

  Other than that, it seems very good, pretty standard.

• IPSEC VPN site to site on Transparent mode

  Hello

  The new version of the OS of the SAA does support IPSEC site-to-site VPN for partners on more Transparent?

  Thank you very much

  Kind regards

  J

  The transparent firewall supports for connections to management only site-to-site VPN tunnels. It doesn't end of VPN connections for traffic through the ASA. You can pass through the ASA VPN traffic using a more extended access list, but it fails to complete connections not frames. Clientless SSL VPN is also not supported.

• How to assign several VLANS in transparent PIX using command line

  I need help in the awarding of two inside and two VLANS corresponding to our PIX 525 outside running code 7.06. I can't find a good link on the configs to site or sample of Cisco.

  Basically, you can have only one inside and an external interface. Take a look at the following documentation:

  -Transparent Preview Mode:

  http://www.Cisco.com/en/us/products/ps6120/products_configuration_guide_chapter09186a0080450b68.html#wp1201980

  «Transparent security apparatus uses an inside interface and an external interface only.» If your platform includes a dedicated management interface, you can also configure the interface of management or subinterface management only for traffic.

  In simple mode, you can use two data interfaces (and if available, dedicated management interface) even if your security apparatus includes more than two interfaces. »

  I hope this helps!

• How to export a transparent EPS?

  I have a logo that I am combining with other elements in Illustrator. The logo must be transparent. It shows as transparent in Photoshop and Illustrator (under "see the transparency grid"). But when I export an EPS puts a white back box all about the logo. I followed the advice of other issues here but can not get this to work.

  It depends on what you mean by transparency.

  Transparency = blend modes, opacity of the levels other than 0% / 100% -, EPS would never support it.

  Transparency = drawings that are not 100% fill the rectangle - Yes quite possible. Warning: PostScript interpreters support this, but EPS previews most aren't. Some applications show the preview the full rectangle, others may assume white = transparent. Do not trust the preview.

  If you can export this kind of transparency to an application and use another application is a completely separate issue, but it works if the apps let and print PostScript is used.

  Caution: transparent cuts by mask pixels are a PostScript 3 construction (transparent cuts by a clipping path are universal). If you do not have a printer of level 3, cutsouts by the mask of pixels will be lost, giving a full rectangle.

• WVC54GCA with Qwest Actiontec GT701 more router D-Link DGL4300

  I would like to be more intelligent.

  Here's the little story, installing the camera outside the Conference on Disarmament did not work, so after reading here, I downloaded the software site and installed by directly accessing ip camera. The wireless camera works if I access it by putting the IP in my network... I can't access it on the internet.  I'm not sure what network settings must be in place within the modem or the router.  So here are the details:

  Modem:

  Actiontec GT701

  Local IP address: 192.168.0.1
  Subnet mask: 255.255.255.0
  Local DHCP: off

  Mode PPPOE, no firewall.  NAT is on.  Now that I read the number double nat, that might be the problem.  But when I put the modem in transparent bridge mode, disable NAT, I lose the internet connection.  I enter the PPPOE details in my router, but that does not really do anything.

  http://I3.Photobucket.com/albums/y59/Camulos/Linksys%20webcam/dlinkwanpppoesettings.jpg

  I submit port 80 in the ip 192.168.0.1 on a guess, hope modem.

  Router (192.168.1.1):

  Port before 80 and 1024, TCP ports, ip address: 192.168.1.49 (address of the camera) what I need to enter information in the UDP box or leave empty?

  192.168.1.49 in the DMZ

  DHCP enabled

  http://I3.Photobucket.com/albums/y59/Camulos/Linksys%20webcam/portforwardsetup.jpg

  If I put my modem in transparent bridge mode, do I need to change the gateway or the dns primary information in the router? Basically, how the router connects me in Qwest? After a reboot?

  Camera (192.168.1.49):

  Works as a network camera.

  ALT port 1024 active.

  http://I3.Photobucket.com/albums/y59/Camulos/Linksys%20webcam/camerabasicsetup.jpg

  TZO seems to be working, followed my IP.

  So basically I'm stuck on whether I need to change numbers, IP addresses of those who, if I need a transparent bridging at all.

  Thanks for reading this.  Any help is greatly appreciated.

  Do not put your modem in transparent bridge mode, it should be in full bridge mode... Try to disable your internal firewall of the router... Check the external IP address on your router installation... The external ip address to view your camera on the Internet... Suppose that the external ip address on your router installation is 66.x.x.x, open a web browser when you are on the Internet (outside your network) type i.e of external IP http://66.x.x.x:1024 and you should see the prompt for username and password for your camera... Make sure that port 1024 is open using a Port Scanner(sometimes port does not open, though you have port forwarding enabled on your router)... Yes, you can also try DMZ...
