PIX | SAA: can a ping host the outdoor iface inside?
Hello
I know how to configure a PIX / ASA in order to control the hosts on different interfaces to ping these interfaces or ping hosts in other segments through the firewall.
But I would like to know if it is possible to ping the external interface of a host segment inside. Or is it impossible?
Thank you
IXF
Hello
all I know is not possible not even if your acl allow icmp. You can only ping your connected to the interface.

Comments can not ping host in a guest only network
Hello
I have a Win XP SP2 guest OS running in VmWare Workstation 7.1.0 build 261024 on a Win XP SP3 host OS.
The virtual machine network is configured in the Config setting.
Problem: Can't ping guest operating system host OS, but the other way works, I ping guest operating system of the host.
Here are the details of config:
Host config:
IP address: 192.168.1.100
subnet mask: 255.255.255.0
default gateway: 192.168.1.1
Config of comments:
IP address: 192.168.117.128
network mask: 255.255.255.0
default gateway: it is empty
DHCP server: 192.168.117.254
Configuration of Vmnet1:
IP address: 192.168.117.1
NET Mask: 255.255.255.0
default gateway: white
When I ping 192.168.1.100 (Host IP) or 192.168.1.1 (Default Gateway) of the customer (192.168.117.128), I get a message from Destination unreachable in both cases. Please advise on this issue.
Kind regards
Neon
Welcome to the community,
Since it is a host-only network, you can test only the vmnet on the host (192.168.117.1) adapter.
If you want to be able to access the other IP addresses, you must configure the NAT is connected by a bridge.

I am running Windows 7 on a computer Tablet laptop of Dell Latitude (it has a touch screen that is not removable, but it turns). My problem is that I can not shut down this computer and carry it from one place to the other without losing all my battery power: you can hear 'ping' when the lid is lowered. If I have to carry that I have to turn off completely, otherwise it will just keep producing this ping and use my battery. Everyone knows this?
This ping me makes me believe that a key is pressed, perhaps due to a letter from the keyboard that is stuck or is bad, or possibly a defect of the product.

Established but LAN-to-Lan tunnel can not ping to a host on the inside
We have two cisco vpn concentrator (3005).
Behind, we use 172.20.167.0/24 (Headquarters)
Behind, we use 172.20.184.0/24 (remote desktop)
We are starting to do a lan-to-lan tunnel, the tunnel establishes no problem.
the only problem is that I can ping only the inside interface of the
hub of central administration. I can't ping (or other
communicate to) hosts
on each subnet.
On each side, you must make sure that all your hosts know that the road to the other network is by the local hub or using static routes on each host, or adding routing appropriate on any device is your default gateway.

Comments can ping host, but host cannot ping the prompt.
Hello. I already asked this question in another discussion, but it has a different title, so I decided to ask my question in a new discussion.
Host: Windows 7, 192.168.186.1, no gateway IP
Client: Windows XP, 192.168.186.2, no gateway IP
If the ping of the comments reached the host. But when I try to ping the host's comments, I get '100% packet loss. How it could be explained?
I take a look at the Windows Firewall on computers and make sure that it is disabled.

10.1.1.10 netmask 255.255.255.255 0 0 Thanks in advance for any input.
Ariel
Yes, it'll be OK. What you can't have is the following:
static (Inside, Outside) 172.18.124.10 TCP 10.1.1.10 netmask 255.255.255.255 0 0
static (Inside, Outside) 172.18.124.10 TCP 10.1.1.10 netmask 255.255.255.255 0 0
and you can't have:
static (Inside, Outside) 172.18.124.10 TCP 10.1.1.10 netmask 255.255.255.255 0 0
static (Inside, Outside) 172.18.124.10 TCP 10.1.1.10 netmask 255.255.255.255 0 0
In other words, you cannot map the port itself to two different ports, in both directions. The PIX will get confused when it receives a packet on the duplicate port and does not know what a host to map to. As everything inside and outside ports map to unique ports on the other interface then you're OK.

The VPN Clients cannot Ping hosts
I'll include a post my config. I have clients that connect through the VPN tunnel on the 180.0.0.0/24 network, 192.168.1.0/24 is the main network for the office.
I can connect to the VPN, and I received a correct address assignment. I belive tunneling can be configured correctly in the aspect that I can always connect to the internet then on the VPN, but I can't ping all hosts on the 192.168.1.0 network. In the journal of the ASDM debugging, I see pings to the ASA, but no response is received on the client.

Hello
-be sure that the destination host 192.168.1.x has a route towards 180.0.0.0 by the ASA gateway.
-Configure the following figure:
capture capin interface inside match icmp 192.168.1.x host 180.0.0.x
capture ASP asp type - drop all
then make a continuous ping and get 'show capin cap' and 'asp cap.
-then check the ping, the 'encrypted' counter is increasing in the VPN client statistics
I would like to know about it, hope this helps

Hi all!
I have weird problem and I hope some of you can enlighten us if necessary.
The background:
My OS is Windows Vista Home Premium SP 2. One day, I installed an application proxy - ProxyCap - as a free trial for 30 days. The application installed a few dll Winsock provider. After the 30 day trial, I uninstalled the app. Then the problems started. Even if the application proxy has been disabled, regular internet links have been completely normal and not affected. It was only after uninstalling the app that I have problems.
The problem:
- The computer is unable to connect one more to any website using the browser.
- My local network seems to be fully functional, which involves a problem of setting the software. I say that my LAN is functional if I am going to sign--> Network and Sharing Center--> view status and look under the "Activity" section, I see the link send and receive packets without problem.
- If I go into control panel of--> Network and Sharing Center--> view status of--> diagnosis, I get the message: "cannot communicate with DNS Server (xxx.xx.xxx.xxx) Network Diagnostics ping to the remote host, but has not received a response."
- Indeed, if go to start--> cmd and ping my DNS server, I get a general failure for all 4 packets sent.
- However, I am able to ping my localhost to 127.0.0.1
My settings:
- My ipconfig/all output: http://pastebin.com/Ksn2k2ja
- DHCP is enabled.
- For the properties of connection LAN--> Internet Protocol Version 4 (TCP/IPv4)--> properties, I 'IP automatically get an address' and "Obtain DNS server address automatically" selected.
- The same goes for--> Internet Protocol Version 6 (TCP/IPv6)--> properties.
- The Sysinternal autoruns--> tab providers Winsock application, tells me that I have the "Hello Namespace Provider' active as a WinSock2 registry entry. It is mdnsNSP.dll and published by Apple Inc.. Who was present before installation of the proxy, and this is for iTunes. Screenshot: http://i1300.photobucket.com/albums/ag86/applemeetworm/winsock_zpsb41ca872.jpg
What I tried:
- I tried to reset Winsock for Vista by clicking Start--> cmd and type netsh winsock reset , and restart the computer.
- I tried to reset the TCP/IP stack by clicking Start--> cmd and type netsh int ip reset c:\resetlog.txt and restart the computer.
- Restart my router.
- Deactivation and activation then my connection to the local network.
Thank you all for helping me with my problem. I would be happy to provide more information as needed. Thanks for the research and thanks offering solutions.
See you soon!
Hi all!
I contacted ProxyCap and support staff has been able to solve the problem.
Apparently, one of my entries in registry Winsock2 (Winsock2, Namespace Catalog5, 5 catalog entries) has been disabled somehow, uninstalling or in my first attempts to address issues after uninstall.
Thanks to ProxyCap and for other people who have tried to help.
~ Congratulations ~.

Diagnostics network ping to the remote host, but has not received a response
I'm trying to figure out if there is a problem with just my laptop not wanting to connect to a local free WiFi, so any help is appreciated. He worked two days ago only to stop abruptly last night.
Windows Network Diagnostics comes back with the error message "Can not contact www.microsoft.com (65.55.12.249)" and "diagnostic network ping to the remote host, but has not received a response.
The only repair option it evokes is ' reset NIC 'wireless network connection ' '.
I can always connect to WiFi using my iPhone, and even a connected laptop computer work Companion. Yet once, if this can be fixed on my end, any help would be appreciated.
Hello BrenJones,
Thanks for posting back. DNS servers are controlled by your ISP. I communicate with your Internet service provider and confirm that you have the good DNS for your network.
Hope this helps J

Is it possible to ping directly from low security high security without translations on a PIX?
For example, 192.168.2.90 is currently natted to 10.0.0.4 by the pix. I want to ping directly from 192.168.2.4 to 10.0.0.4.
I can certainly ping directly from 10.0.0.4 to 192.168.2.4.
Please let me know if you would like to see the complete config.
I hope I understand your question completely. You try to ping from one interface to another on your PIX. This URL explains how this can be done.

Cannot ping via the VPN client host when static NAT translations are used
Hello, I have a SRI 3825 configured for Cisco VPN client access.
There are also several hosts on the internal network of the static NAT translations have a services facing outwards.
Everything works as expected with the exception that I cannot ping hosts on the internal network once connected via VPN client that is internal IP addresses have the static NAT translations in external public addresses, I ping any host that does not have static NAT translation.
For example, in the example below, I cannot ping 192.168.1.1 and 192.168.1.2, but I can ping to the internal interface of the router, and any other host on the LAN, I can ping all hosts in the router itself.
Any help would be appreciated.
