  Maybe it's because proxy ARP on the pix. You can try disabling this interface with the command "sysopt noproxyarp.

• ASA mismanaged webvpn cascading connections

  I'm trying to get a webvpn configuration to run with two ASAs which are cascading. Each ASA requires the user to connect to the webvpn. Practically, this means that you connect to the ASA to first, which, from the successful connection, should divert automatically you to the login screen the ASA webvpn cascade with a command of 'value https://homepage.

  It does not work correctly because the first ASA never presents you with the webvpn ASA connection second, but instead you will see the login of the ASA first again. I suspect that this might have something to do with cookies or the way ASAs calculate the special URL that they present the user's browser...?

  Furthermore, no matter what other web HTTPS service works properly when they are referenced as a home page, it won't work with a second ASA. In addition, connecting directly to the ASA second works without problem.

  Someone has any idea how to solve this problem?

  Thank you

• It is safe to connect to the internet to update XP if the computer has not been used for a good year or so?

  Hi all - I have another laptop which has remained unused for probably over a year or more, and I want to start using it again. It works under XP, and currently has Service Pack 2 installed. My question is: is it safe to connect to the internet now and start downloading all the required Windows updates? My concern is that, as just like the anti-virus, firewall, even Windows itself have not been updated in so long, it would be imprudent to start the internet connection at this point? Is it safe to go forward and to connect and update, or is it better to download updates etc on another computer, put it on a disc/USB and then use it to install updates? Thanks in advance!

  Consider that he is therefore authorized to connect the computer to our broadband services to update the anti-anti-virus/firewall?

  Yes, as long as the firewall is turned on and that's the first thing you do online (i.e., no surfing, no audit e-mail, no chat, no download of anything else).

  The Windows Security Center will let you know if something went wrong.

  You're welcome and thank you very much for your comments!

• ASA 5505 ASDM VPN connection problem

  Hello

  We are running a version of firewall ASA 5505 8.4 (4) 1. The ASDM version is 6.4 (9).

  The problem is when the creation of remote access VPN connection, it works fine for about 2-3 days.

  After that, the VPN client cannot connect more and gives the error code 789.

  In this case, the VPN clients are clients of Windows 7 from different remote networks with the same problem scenario.

  Windows 8.1 clients cannot connect at all and show the same error code...

  All connections go through the keys defaultragroup and preshare match on both sides.

  When the user to connect attemps I receive the following text in the log of the ASDM:

  6 April 10, 2015 10:52:39 group = DefaultL2LGroup, IP = 5.240.31.116, P1 retransmit msg sent to the WSF MM

• ASA 5510 IPSEC VPN connection problem

  Hello

  We have an ASA 5510 (ASA version 8.0) of remote access VPN configured and works most of the time, but there is a problem when you have more than one client that connects to the same office remotely.  When the first VPN client is connected to the remote desktop, everything works fine, but when the second client connects to the VPN, it connects fine but do not get any traffice return to customer.  I can see under monitor-> statistical VPN-> Sessions-> remote access-> Rx Bytes is 0. Both connections are from the same public IP address of the remote desktop.  I changed some settings on NAT - T and a few other things, but without success.

  Could someone help me please how to fix this?

  Thank you very much.

  Make sure that customers use because that probably her you're not. (default value is NAT - T).

• The device or resource (127.0.0.1) is not configured to accept connections on port "The World Wide Web (HTTP) service".

  Hello

  I just deploy the tomcat in windows server 2008 and to test whether it is installed correctly. When I opened the IE9 and type in http://localhost: 8080, he goes to the homepage of tomcat successfully. However, when I slap http://127.0.0.1:8080, it shows that Internet Explorer cannot display the webpage (normally, these two methods are the same for the homepage of tomcat). Then I try to diagnose the connection problem. The problem found is - the remote device or resource does not accept the connection. The device or resource (127.0.0.1) is not configured to accept connections on port "8080".
  Then I tried the same procedures in my own laptop, there is no problem. So I wonder if there's some features are disabled on the windows 2008 Server. Can you help me?

• "The internet connection speed" Vs "the speed of a wireless adapter.

  Hello

  I'm subscribered of a DSL with a speed of 512 Kbps (kilobits per second).

  However, when I tested the speed of my internet connection with a variety of Web sites, the speed of a wireless router test while wirelessely connected to a wireless router, I have not found any speed of 512 Kbps.
  What I found is shown on screenshots below to test the speed of connection to internet Web sites.

  

  

  

  As a result, my question are:

  First: What would be my answer if I asked about the speed of your internet connection is? Is there a difference between the speed of a LILY and the speed of an internet connection?

  Finally: In the screenshot below, the speed of the wireless adapter, I think. If so, what advantage is there this speed?

  

  Traditional math units go up (or down) in thousands so yes 1000 K = 1 M. computers have slight variation because in some cases, it is 1024 but the difference is not significant.

  The A in ADSL is asynchronous for the upload and download are not equal. As that data consumer is not serious to you, everything you send upwards is requests for web pages where are small compared to the downloaded pages.

  European providers stuck to the same speed of upload years even if the download rate has increased.

  One of the problems we have is that there are people like you stuck at 1 / 2 Mb/s using systems designed for multi-Mb of Microsoft networks.

  Hello

  Seems to me that his dynamic State PAT shot meant for Internet traffic

  Phase: 6

  Type: NAT

  Subtype:

  Result: ALLOW

  Config:

  NAT (inside) 1 0.0.0.0 0.0.0.0

  is the intellectual property inside everything outside of any

  dynamic translation of hen 1 (WAN. IP. ADDR.162 [Interface PAT])

  translate_hits = 6186208, untranslate_hits = 145616

  Additional information:

  Translation dynamic 192.168.21.100/0 to WAN. IP. ADDR.162/12936 using subnet mask 255.255.255.255

  So you might miss the NAT0 configuration for this connection

  Do the following

  Issue the command "Display running nat" and you should see a NAT0 configuration for the 'inside' interface. Something like that

  NAT (inside) - 0 access list

  Next, you will need to check the ACL configuration

  See the list of access running

  You can add local and remote network that need to communicate through that VPN L2L connection to this ACL

  So for examples sake lets assume that your ASAs directly related "inside" subnet needs to access the remote network, and then you would add

  ip 192.168.21.0 access list allow 255.255.255.0 10.50.50.0 255.255.255.0

  So use the above configuration format with good source and network of destination, as well as the correct name of the ACL and add the required ACL lines and then try to host LAN connections.

  Hope this helps

• Third-party SSL VPN ended the DMZ ASA

  Hi all

  Any help is appreciated. Is it possible:

  I have a DMZ set in ASA 5520, and worked well so far. The DMZ subnet is 192.168.10.0/24 and IP on the DMZ interface is 192.168.10.1. Now, I'm trying to add a third-party SSL VPN device (not Cisco). The device has an IP 192.168.10.101. The SSL VPN appliance will give IP addreess SSLVPN customers in the range of 192.168.20.x. After the connection is established, the client is indeed getting the IP addr 192.168.20.x. However, clients are unable to connect to the internal LAN. If I change the IP address range clients on the same subnet that the area demilitarized, everything works. My question is that, as customers SSLVPN are complete on the demilitarized zone and get a different subnet IP address, how can I / road map these addresses before they6 can access internal network inside the interface, or it can be done at all?

  All advice is appreciated.

  You just need to add the routes appropriate on the SAA for this pool. And also on any Layer 3 routing devices inside the ASA.
