• remote access to manage the Firewall works not

  I can't connect remotely ASDM, works very well on the management port. I can't either SSH remote for ASA.

  I have a VPN IPSEC of L2L with a SonicWall working to the 192.168.1.0 subnet. It connects on the external interface.

  I work SSL VPN AnyConnect. Remote users connect their browser to the external interface, click AnyConnect and are directed to their subnet by a bookmark.

  I can connect to the external interface with a VPN IPSEC client and then use SSH to manage my switches in the demilitarized zone and inside.

  On the spot, I can manage the firewall traversing when directly connected to the management interface. (Console works too).

  But I can't remotely manage the SAA itself! My config is attached. Any help will be appreciated!

  Hello

  Since you have the 'management-access to inside' command configured, you will need to connect inside the IP interface when you access the device through a virtual private network, rather than the external IP address. However, you are also in the bug following in 8.4 (2):

  CSCtr16184 - To-the-box traffic switches vpn hosts after upgrade to 8.4.2

  To fix, you must add the keyword 'search route' at the end of the following NAT rules (anything that overlaps your inside interface subnet):

  nat (inside,any) source static obj-172.16.0.0 obj-172.16.0.0 destination static
  obj-192.168.1.0 obj-192.168.1.0 no-proxy-arp route-lookup
  nat (inside,any) source static obj-172.16.0.0 obj-172.16.0.0 destination static
  obj-172.16.32.0 obj-172.16.32.0 no-proxy-arp route-lookup
  nat (inside,any) source static DM_INLINE_NETWORK_2 DM_INLINE_NETWORK_2 destination static obj-192.168.1.0 obj-192.168.1.0 no-proxy-arp route-lookup
  

  Hope that helps.

• Site to site VPN tunnel - cannot ping the second interface of the firewall peer inside2

  I have two ASA 5505 firewall each with a basic license: FWa and FWb. currently there is a VPN tunnel between them work. I added a second (inside2) interface to the firewall, FWb, but I can't ping firewall FWa, so that I can ping the inside interface of FWa.

  I can ping the FWb inside interface 192.168.20.1 from the FWa inside 172.16.1.1 interface, but I can not ping to the 10.52.100.10 of the FWa FWb inside2 interface. I can not ping the gateway host FWa 10.52.100.1.

  Hi odelaporte2,

  Is very probably the "access management" command is not applied in the second inside, only inside primary (see the race management) which will confirm.

  This command can be applied to an interface at a time, for example, if the law is now applied to the inside, it can not be applied to the inside2 at the same time.

  It may be useful

  After having thought about it twice, it's clear. I wrote to change because it is a good practice, but with the ASA on the other side, it is necessary.

  If you use the output as the destination of a route interface, the router must be able to arp for the IP of destination (for each that is used) L2 address of next hop. The other side (the ASA in your scenario) must have a proxy-arp enabled for this because demand is not a configured address.

  If you configure an IP address as the next hop, the router must only address L2 a jump next-address IP used in the static route.

• PIX 501 in the firewall of the Web server

  Hello

  At the suggestion of a colleague, we bought a firewall PIX 501 to protect our new Win2003 web server and a UNIX/Oracle DB server.

  I've never worked with before firewalls.

  Our servers are located in a cage at the ISP and belong to us. There are only two servers providing web site. I have read the documentation in the Getting Started book and it does not answer my question.

  We have 2 web sites with different IP numbers on our web server. Let's say 140.5.5.4 and 140.5.5.5. I understand that I have will redefine the numbers with the firewall (192,...) but I do not understand how the routers at the ISP will be able to route requests for two websites to the firewall when it has one IP number, say 140.5.5.1?

  Any help is appreciated.

  Thank you, Jerry

  Jerry,

  what you are referring is called port forwarding. Whether you a PIX with a public IP address 12.1.1.1 and your web servers are respectively and 12.1.1.2 12.1.1.3. Port forwarding is really a 2 step process:

  * a static translation of the public IP address of the PIX (12.1.1.1) at the address of the web server (12.1.1.2)...

  static (inside, outside) tcp 12.1.1.1 12.1.1.2 www www netmask 255.255.255.255 0 0

  * an intermediate statement basically "all web requests should be allowed in the pix outside of the interface"...

  driving permit tcp host 12.1.1.1 eq www everything

  Here is a link that will help you to clarify this point:

  www.Cisco.com/warp/Customer/707/28.html

  This should help you get started. Regarding the basic configuration, it takes config examples on the Cisco site, if you have access CCO.

  Let me know if it helps.

• IP in the firewall does not work in ESXi 5.5 are they allowed?

  Hello to all users of the VMWare communities,

  I am new to the management and use of VMWare.

  Recently, we bought a server with VMWare VSphere ESXi 5.5.

  It is on an ISP, with a public IP address in which VMWare management network is configured. By default, all the management ports are open (SSH, Web, VSphere Client ports, and a lot of more ports I think I won't use...).

  The problem is that I want to protect as much as possible this host. I have no external firewall to this host to close unused ports so I want to use the built-in firewall.

  I am trying to use the feature "Allowed IP addresses" the integrated firewall of ESXi, but it does not work. I want to only allow SSH connections and management via vsphere client of static public ip address from my office, I put this IP address in the settings of the firewall for each service, but apparently it does not work, I can still continue to access across all services.

  No idea who might be the problem?

  Thank you very much.

  Finally, I found the problem.

  The firewall is disabled!

  I connect to ssh host and do: 'esxcli get network firewall' to get the status of the firewall and after seeing it is disabled, "esxcli network - enabled true firewall.

  I Don t know why, but by default in the installation of vmware, the firewall is disabled.

  After that I enabled, apparently it remains enabled between restarts.

  Thank you everyone (for nothing ;-\)

• Firefox 36.0.1 problems with addon and MP sent after notification of the firewall on Win7

  Yesterday, I had a problem after clicking on 2 or 3 times to open the firewall et seq. asked to unlock even if I did a long time ago. I'm not an admin, but I know that the local administrator password that allows me to put things in the control panel. After what's happened alert HitmanPro cannot load on FF opening; PIX downloaded with Picture Picker addon are not saved in the destination folder, even if the message indicates that they are registered and also I can't send pms in some sites. I don't know what other damage is done.

  It seems that the bug in the picture picker is because the new FF updated (it works in it), it is the same with Facebook album downloader. There are numerous answers in their pages. MP is a temporary problem, and IMHO, all the things that I've met are because the update. I would ask some mod to close my question.

  • Make sure your Internet security software is up-to-date (for example, you are using the latest version).
  • Delete Firefox to list your program of programs approved or recognized. For detailed instructions, see

  The previous version of Firefox has not solved even after that I removed and then Firefox again added to the firewall exceptions list.

• last version of Firefox can not ensure a secure connection without disabling the firewall, why?

  I've upgraded to the latest version of Firefox and now whenever he goes to a secure connection, it debits far and doesn't connect or said that the connection was refused. I'm under Firewall PC Tools and strangely when I turn off the firewall, it connects. I don't really like it. I tried to remove Firefox to the list of applications and add new, but it did not help.

  One possible cause is security software (firewall) that blocks or limits Firefox or plugin-container process without informing you, possibly after the detection of changes (update) for the Firefox program.

  Delete all rules for Firefox and the plugin-container in the permissions list in the firewall and leave your firewall again ask permission to get full unlimited access to the internet for Firefox and the plugin-container and the update process.

  They did something with firefox 3.6.8, which upsets the McAffee Firewall currently. Since the upgrade, I get the firewall Alerts pop ups. If you click on the block (which could have your children), then Firefox will be blocked completely.

  If you dig in the McAffee Firewall tools-> program authorities, you will likely find that Firefox listed as "blocked."

  On my machine, the entry is for 'Free' only and I now get alerts. I think they will disappear if I switch it to "Full". But I'm reluctant to do this, why a browser should accept incoming connections, why this change has been made and what benefit is it for us as users?

  There's no advantage having.

  Update the iMac has more benefits.
