Ping Returns Same Address All The Time?
Nov 22, 2011
We recently upgraded to Windows 7 at work and my laptop was part of the first deployment. Laptops are imaged so that all configurations/software are already set and done. My problem is as follows, my laptop is part of domain, when I am at work I can ping anything just fine (network computers, printers) BUT when I am at home, I can't even ping my own PC. It returns back with the same address over and over. No matter what I ping when I am at home, it returns back with the same address. I can ping blah and it will display same address over and over. The weird part is I can ping websites no problem, but if i ping random names it will format as follow.Lets say I want to ping lost, below is what i get (I made changes to hide domain and IP)
Pinging lost.domain.com [70.99.199.99] with 32 bytes of data:

Notice how my domain always shows up? When I am connected to the VPN at home, I have to log onto our intranet using the IP, I can't use the name, it wont direct to it.

I think I'm missing a basic step here. In setting up a RV220W device behind either a cable modem or a DSL modem, the address that is being returned is not the public IP address of the modem, but rather the private IP address assigned by the modem to the RV220W. Doesn't matter for normal web access but trying to set up a VPN tunnel fails due to the inaccurate IP address.
If I do the same thing but use the dyndns.com application on a computer behind all of this (connected on the private LAN of the RV220W via cable), it reports the external IP address correctly. That works in some locations if I have an always on computer to load the application to. In some cases, however, there isn't such a computer to leave dedicated to running the separate program.
Since this works, and the RV220W doesn't, there is some difference between the Cisco implementation and the dyndns.com implementation.
So, is there a way to get the RV220W to return the true external IP address, or is it stuck returning a private address?

I'm working as a network engineer for a service provider, and we had just gone through a pretty large scale upgrade throughout our network and service.But not long after the upgrade (or maybe ever since the upgrade, we can't confirm this because we probably missed it out due to many other links to be tested), we met a peculiar problem.Everything seems to be running fine most of the time, but there has been some weird 'ghost-like' activity which have been causing inconsistent network disruptions. At times, certain portions of the network can't communicate with other subnets.And most obviously is the problem with a continuous ping and a traceroute simultaneously. Ping is usually normal, but until a traceroute is attempted, it times out at the same time as tracert fails to obtain the route.Besides, performing a ping from the 2nd closest hop address, 10.250.253.251, which is a cisco layer 3 switch also has problems, the results shown are as belowType escape sequence to abort[CODE]

I have a brand-new WRT160N router (just installed FW v3.0.02) that I am using in mixed mode, 20MHz only, Channel 11, not filtering anonymous requests, beacon at 2306, RTS at 2307, fragmentation at 2346, MTU at 1400.
These settings bring the response from a simple ping command over the wireless network down to approximately 6ms on average, which is good. However, when I still noticed inconsistency with my internet response over wireless, I decided to do a test.
By simply running the "ping" command on 192.168.1.1 (the router address) over the wireless network repeatedly (approx 3 seconds between commands), I can see that approximately every 65 seconds or so, router response time increases to over 100ms for a few seconds, then decreases down to 6 ms or so for another 65-70 seconds. See the chart below. The interval looks pretty consistent to me, with the exception of one stretch where it goes for over two minutes without a spike. I see this pattern regardless of what else I'm doing over the network. I do not see this behavior running the same test when physically wired to the router (ping response time is a flat line at 0ms).

I have newly deployed network. I have two ASA5520-AIP20-k9. both connected to ISP and configured as Active/standby failover. the ASAs were working fine at first but later on, the internet connection becomes very slow. the ping reply i am getting from my next hop(ISP router) varies during the peak hour is some times in 2000 msec or above but during off hours, the ping reply time is 1 and 2 msec. when I directly connect my laptop to the link that comes from the ISP its ping reply is 1msec and 2msec. I thought the ping reply of the ASA5520 to the ISP gateway should be constant and should be 1 and 2 msec regardsless of the traffic passing through the firewall.

I have a secondary router (E1200) on my home network, connected LAN to LAN. I use it mainly for wired connections, and it does work for that. But when I try to access this router through the IP address, I get a page that says only "ACT_IDLE". Occasionally, I am able to access, but I've found no pattern to when the router is accessible and when it is not...mostly not. Bad router? Bad setup? Bad owner?

ASA5510, ASA 8.0(4), ASDM 6.1(5), this is a productino ASA with plenty of lookups working through its 3 interfaces - outside, inside, dmz. The problem is a new use. I've segmented a switch on the inside network with a VLAN, and have a workstation routing through the switch to the default VLAN where all other hosts on the inside network reside so far. The ASA inside interface is the default gateway for the inside network. My test worksttion can PING inside hosts, so the static route is OK.
ASA 10.1.1.2/16 DNS Server 10.1.5.1/16

------------------------------------------------------------------

Switch 10.1.8.20/16
[code]....
But lookups fail, Wireshark says the test workstation sends, the dns server receives and responds, but the test workstation never receives. I used the Packet Tracer tool, it gets to the last step syayin OK then finally "inspect-dns-invalid-pak". I can't find any more there to tell just what is invlid about it. So I'm trying to figure out global inspection. Here's an extract from the config:
class-map inspection_default
match default-inspection-traffic
!

policy-map global_policy
class inspection_default

My galaxy tab has a difficult time connecting to my wifi. it seems that the only time my galaxy will connect is when i change the DHCP reserved IP address i setup for it. it wouldn't connect before i setup a reserved IP address. now my galaxy tries to connect over and over and won't until i change the reserved IP address by a few digits.the router is an older d-link wbr-2310. i know routers occasionally die, but this is the only problem i have with it.

I'm trying to examine the ARP table on specific phy ports on a SG300 switch. The Cisco CLI guide shows this syntax:
show arp [ip-address ip-address] [mac-address mac-address] [interface-id]
Using the CLI and the "?" key to get assistance, I'm not successful:
switch3#show arp
configuration Display ARP related configuration
ip-address Filter ARP show by IP
mac-address Filter ARP show by MAC
[Code]...
I don't have http server enabled, I prefer SSH and CLI to do my work.

i have few questions about MAC adress limitation. We have in our network cisco RV042 router, SLM2048 switch and WAP4410n AP.
My 1. question: is it possible to disable internet connection for concrete mac adress based on scheduling?
For example: between 23:00 - 5:00 this mac adress will not connect to internet.
If yes how i could do that?
My 2. question: is it possible that if this "mac adress" is connected for 5 hours than disconnect it for 6 hours?

I've just bought a pair of WAP121 for testing and validation. I've set it up properly (user/password, IP, management vlan, NTP, SNMP, 802.1x, etc). So far, so good, everything worked as expected. I've downloaded the configuration to my PC, and also saved it to startup-config. I've powered off the unit, went for a coffee, and powered it back. All my settings were lost.
Tried to restore settings from the file downloaded to my PC, but no luck. After reboot, it was factory clean, no trace from settings in the backup file. I've set it up again by hand, power cycled it, and the **** thing reloaded to default settings.
Faulty unit, I thought, so I opened the other one I have, and repeated the whole thing, but same results. Test were made using the power adapter supplied but also tried with a catalyst 2960 with PoE.

We have a number of 4507s. Most are managed via VLAN 1 address. All have multiple VLANS for traffic control. When I do a show ARP or show IP ARP the command only shows VLAN 1 info. No entries for any of the other VLANS on the switch.

2 windows 7 machines.at work..They are both laptops. one acts as a server for a piece of software to the other one.on the "client" laptop I can map a drive to the "server" and browse files through that maped drive etc.I can also ping the IP address of the "server" but I get a timed out when I try to ping the computer name.Server had Macafee firewall, I uninstalled that, and I turned off Windows firewall on both machines.the software needs to be able to ping by name I guess in order to work..

I upgraded my Linksys RV042 firmware to 1.3.12.19-tm and exported the config file, then tried to convert it using RV0xx_Migration_Utility_v1.0.2.2 in order to import it to a new Cisco RV042 (v3). The migration utility returns a config create fail message and fails to convert.
The LOG file ends with:
Get PORT_101 VLAN Group setting fail.
***log end***
how to make this work or how to move config file to v3?

I bought a usb printer server to connect my usb printer to my router. USB cable to the print server and cat 5 from the print server to the router. The print server has a static fixed ip of 169.254.10.10 and a subnet mask of 255.255.0.0 I can ping the printer server and it works perfect from my windows 7 laptop. When I attempt to set it up on my windows xp (SP3) laptop I am not even able to ping the 169.254.10.10 address. On the windows 7 laptop i can navigate to the print servers menu by placing 169.254.10.10 in the address bar of internet explorer. No so with the xp laptop.What is different about the ip configuration between win xp and win7. how to get the xp laptop to "see" the print server. Want to keep the print server at the default settings if possible.

I have a HP Pavilion DV6000 that I just tried connecting to my network through wireless. It says connected, pulls an IP adress, and gets the gateway but it will not pull up web pages, ping google, or ping any other computers on the network.. I have one other computer connected to the network, wired. It can connect fine to webpages, but it wont ping the HP laptop. The router interface shows that it's giving the HP an IP but thats all it seems to be doing..

Is there anyway to force the xbox inside the router to grab the same ip address everytime it comes on? Other than changing it on the console via a static ip? Xboxs dont like static Ip address and its getting annoying?

I just got a new RV042. V3 Hw.For setup and testing before putting it in action, I've attached the WAN1 side to my internal network.But it fails to get an IP address, and the log shows: "Infinite lease time, exiting".My current router on the LAN is giving out DHCP addresses with 3 hour lease time, and I've checked with the PC's on the LAN that this is correct.The routers DHCP status shows that the lease time for the RV042 is 3 hours ahead.So why does the RV042 complain about long lease time ?Is there a way to avoid this error from occurring?
I have tried to change from 'Gateway' to 'Router', but this does not change anything.Also tried a factory reset, with no luck.Fw is upgraded to the latest 4.0.4.02

I'm running into a strange problem and cant seem to figure it out. I have an asa running 8.2(1). I have an ipsec vpn setup and working great. I can ping hosts on the inside of the network and everything seems to be fine. However there is one single ip address that i know for a fact is live, but i cannot ping through the vpn. If i ping the address from the asa i get a reply, if i ping the address from inside the network i get a reply, but if i ping when connected through the vpn no reply.

i have a site to site vpn stablished, the vpn works fine (while is up), i have a cisco asa 5520 and the other end of the vpn is a jupiter device that for technical reasons needs to send a continuos ping and when it does not receive a reponse back it brings down the vpn tunnel and reestablish it again. while the vpn is up traffic flows perfectly but because i m unable to repond to the ping the vpn is brought down as reestablished by the jupiter device. the jupiter device pings the encryption domain which is an ip that is natted to the real ip in the inside network. this is my configuration of the vpn:
AAA.AAA.AAA.AAA is the ASA public ip in the outside
BBB.BBB.BBB.BBB is the jupiter device ip (part of the object group IP_LIST)
CCC.CCC.CCC.CCC is the nat ip on the ASA
10.21.0.164 is the real address in the inside(code)

I have a problem with an ACE 4710 regarding to the ping of especially one VIP address.
[code]...
At the Box I setup 10 Servcies, all with different VIP addresses, also the IP is not used duplicate somewhere in the network.
in the class defined under Policy-Map Multi-Match I setup identical to the others loadbalance vip icmp-replay active, the VIP is usable by the defined service http, the serverfarm is up and running all ok so far but this VIP does not respond to ping even the correct arp resolution was done.
I started also a capture locally on the ACE and see the ICMP - Echo coming in, but the box sends no echo-reply back.
In the access-lists Management and so on I allowed icmp and also on all interfaces the icmp guard is disabled...

We are trying to isolate the fault. From Aggregator a router, we are receiving MAC address of distant end ethernet interface of a SDH box and vice versa is also possible. However ther is no packet received. My question is does ping test is must to see if the path is through or just receiving MAC adress at both ends would mean that packets have to go over the path.

I would like to allow PING on RV042 from WAN side only from specific IP address, but when I set the rule, RV042 does not respond on WAN side, because Block WAN Request is Enabled.BUT! When I disable "Block WAN Requests", now any IP can ping my router from WAN side. Although I set access rule to Deny Ping from WAN side to anyone, it still responds.

I have Latitude E6410 and connect to internet through wireless network to Zyxel ADSL modem. My problem has started 20 days ago when I was connected then I was disconnected from internet. The status is as below:
- I can ping the modem which means the laptop the link between modem and laptop is working while I can not ping any address or website even the provider's DNS. At the same time, if I connect the LAN cable, every thing is working properly. I tried with different laptops and there was no problem. To resolve the problem temporarily, I have to restart the modem or change the IP for my wireless card. In this case it works for another 30-60 minutes. the issue is the same when I use different modem.
