I have 3 2620xm routers connected via dte/dce serial connections In a lab.One of the routers Is also connected to a 2950 switch.
The 2950 switch connects to an unmanaged tp-link switch that Is connected to a dsl modem/router.I have Internet access via the 2950 to my laptop.
I have ripv2 enabled on all the routers and It's working fine.The dsl modem, switch and connected router are on the same subnet.
When I ping the dsl modem via the 2950 or via the router connected to the 2950 , It works 100%.If I ping the 2950 from either of the other two routers , It also works 100%.I can't ping the dsl modem however from the other two routers.I've only been studying for the ICND1 so maybe there's something I'm missing here.
configuring 2620 cisco to cable modem for internet.I'm setting up a lab to practice and am having trouble getting this to work.Made several configs that don't work and starting over form scratch.
Router ISP >>> Switch 2940 >>> Router 2620 >>> Host (Tacking dhcp from my 2620)
I got servers and other switches 2950 working perfect from the 2940....but the 2620 or even a Switch 3550 (in router L3 port), has the same issue...do not share connection with Host's behind them, I got IP on the host, pinging the Fa0/1 (dhcp), pinging the Fa0/0, but cannot ping the GATEWAY and not surf the internet.
From My Router that connects to Cable modem i am unable to ping website 4.2.2.2I am able to ping all other websites fines.Same website i can ping from my pc and all other switches fine.Router has only 1 ACL thats for NAT.
A friend recently re-installed windows XP on their HP Laptop. They were connected wirelessly with a Linsys router (model wrt54g.1) and an RCA Cable Modem. The Cable ISP can ping the modem and gave me the IP address over the phone. I cannot ping the modem even when I take the router out of the loop. The network card (i1394) in the Laptop is functioning normally and I can see traffic on the modem (both the Cable Internet light and the PC activity light are flashing green) the ethernet port on the laptop is also flashing (amber). However I cannot reach the internet and cannot even ping the modem. The modem is brand new..
*I have 2 cisco routers 2811 router A&B*using 0/0 for WAN and 0/1 for LAN on both routers*both routers are connected together with crossover cable to 0/0. recieve link and activity*both routers are on the same subnet Router A:0/0 192.168.1.1/24 - router A:0/1 192.168.2.1/24 ; Router B:0/0 *192.16.1.2/24 router B:0/1 192.168.3.1/24*I can ping the inside and outside address of both router from PCs connected at its respectable end. *PC A 192.168.2.2/24 PC B 192.168.3.2/24 *when connected to router A 0/1 and I try to ping router B 0/0 it times out in DOS* but I AM (CAN) able to ping from PC A to router B 0/0 in hyperterminal, telnet and Cisco SDM. I just CANNOT ping in DOS?
I have created a site to site Ipsec vpn with a cisco 2610 and a linksys RV042. Running a show "crypto isakmp sa" command I get a qm_idle status and when running a "show crypto ipsec sa" I see that packets are being decrypted and encrypted. Also when running the "show ip access-lists" command I do have matches to that connection.The problem is that I am unable to ping hosts from one network to another. For example, from the Cisco router in network 192.168.0.0 I am unable to ping the remote network 192.168.2.0 and vice versa.
I am not sure what is happening. Do I need to create a route to that remote network? I guess it could also be a problem with NAT or an ACL.Here is what running-config shows:
I am connecting a 2600 router to an ISP. Interface 0/0 is connected to the ISP using DHCP. Interface 0/1 is connected to the inside providing DHCP services to the inside. At least it should only be providing DHCP services to the inside. I also have a public static IP that is NAT to a private static IP. Everything is working except the computer on the static IP. From the router I am able to ping inside and out from each interface. I am able to ping both interfaces of the router from the computer on the static IP but I cannot ping outside the router. If I do a debug all I see a reject for the gateway of the static IP but it has “mobile IP” in the text string. Not sure what mobile IP is relating to. Networks are as follows:
I've been called upon to fix the SSL VPN issues in our ASA5505. The issue I am having is that I am able to log into the vpn, access the internet, but I'm unable to access anything on the LAN. I can't use ping or use DNS.
I'm using ASDM v. 6.2(1) and ASA verison 8.2(1). I'm not comfortable using the CLI and prefer the GUI.
We have many CT/MRI etc. machines and Servers in the Hospital LAN. Now intermittently we are loosing the LAN connectivity i.e we are not able to ping any system from any node inside the hospital network for sometimes, after some time it will start working and then again it will stops again.We are using procurve switches and also we are not using any router
I'm trying to do port forwarding on my DIR-615...first of all I need to be able to ping the router from outside! I did enable the ping options to allow request from WAN...still don't work!!I removed the router and plug my laptop directly on my cable modem adapter and I'm able to ping my IP address (did put the same address the router had)...so, the IP is OK and it is possible to get in the modem from outside.I did plug back the router, and still not working...I did some trick like enable all IP with the Inbound filter...give access to few MAC address that I have to give more chances to get in and still not working!!!
I have an Cisco EA2700 router and a Motorola SB6121 modem. If I'm connected to the router wirelessly or through any of the lan ports, I can't visit the modem's diagnostics page at 192.168.100.1. If I connect directly to the modem, it works fine. Also I cannot ping the modem through the router, just get a timeout. My ISP is Comcast.
I am currently working on a 1941w router. The problem that I am having is that I am unable to ping the switch that is directly connected to it and I am unable to ping from the switch to the router. If I take the address off of vlan 1 and move it to gi0/0.1 the pings work, but then client traffic on the wireless ap inside the 1941w fails.
Here is the releveant config off of the 1941w

im trying to connect a dell MD3000i to a Cisco 3750-s but i am not abel to ping the server.the status is up and Protocol is up. but still nothing.i configerd the port to be a acces port and also at trunk port but still nothing is happening.
host PC (192.168.9.3) -----> gateway (192.168.9.2) ----- Pix E1 (192.168.9.1)/Pix E0 (81.x.x.250) ------ Internet
The 192.168.9.2 gateway is a 3560 switch connected to the PIX. I can ping out to the Internet via IP from the PIX, but not via the host PC (192.168.9.3) on the LAN. PIX and gateway configs below. Am I missing something that's preventing me pinging out to the Internet from the internal LAN?

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)
This is what I have as a setup:BT Home Hub wifi routerPC with Windows 7 Home premium connected via ethernetMacbook Pro with OSX10.6 connected via wifiIt feels like i've tried everything to get this working. As far as I can see the settings are all ok but I've noticed that I can't ping the PC from the mac although I can ping with success the other way around tried traceroute from the macbook and it gives me this so it is able to see it somehow...Code:traceroute to 192.168.1.66 (192.168.1.66), 64 hops max, 52 byte packets 1 alistair-pc.home (192.168.1.66) 1.724 ms * 1.151 msNot sure where to go from here. I think discovering that ping is failing is a good start to diagnose.
I have a home network of 3 cmputers. DHCP from router. 1 computer is not getting address. But if I assign it one, with same gateway and dns(not a duplicate ip of others), it can ping internally, and outside. I can do tracert to 8.8.8.8 and ping it (google DNS). But I can't get to internet. So - i can get out, but nothing coming in. I have checked firewall.
So I got 8MB/1MB internet at home and so far I haven't been able to fix the problem I have: if I watch youtube and try to play pretty much any game that uses internet, i go from 70ms ping to 300ms++ instantly. Even if only two computers are on and both have the same game on, just opening a Google Chrome with one youtube tab on causes a HUGE ping. Two computers with youtube and CS 1.6 on shouldn't cause that.My setup is as following: old ZyXel ADSL-modem 660 series with one LAN port and web config (so it has settings to be modify) and a Linksys WRT54GL with DD-WRT v23. All computers I use run either 32-bit Windows 7, Vista or XP. However, it doesn't matter which computers I use; I've tried this with more than 5 computers already. All cables have also been tested and changed.
Recently we have configured new site where we are unable to ping global DNS from routers and switches.Checked in the firewall ICMP is allowed.The thing we did is we made Native vlan as vlan 10 (Data vlan ) instead of vlan1. Do this is the issue for not pinging.
I need another set of eyes on my config. I am trying to set up my router for a basic connection for the time being. I set my gig 0/0 port to dhcp I see traffic being sent and recieved but I can not ping 8.8.8.8. I am connected to a basic comcast modem from 0/0 I have also tried setting gig 0/0 to 100 full. I do have IP routing enabled. I believe I have my acl's configured correctly. I am wondering at this point if I need a static block of IP's from comcast.
I have 2 routers, one is an Apple AirPort Extreme with a static outside IP address, I also have a Cisco 871 with a static outside IP address. The Airport Extreme connects to a switch on the private network and has an IP address ending in .1. The Cisco 871 connects to the same Private network and it ends in .2. The 871 is setup as a VPN Server. now when clients connect to the VPN they can ping the VLan IP Address on the 871, but they can t ping any other hosts on the smae network. The hosts on the private network can ping the vlan on the 871.
I have setup 5505 ASA for Testing purposes. It has static route to layer 3 switch on outside interface that goes to the internet.

I' d like to have some support for a very-basic PIX firewall configuration. I 'm dealing with PIX 515E. Inside hosts can ping inside interface , outside hosts outside interface and so on. Simply i cannot ping outside interface from inside hosts, Inside host-192.168.1.0
Outside - any host like google.com, or to check my isp link's dns ip. I have attached the pix configuration text file to test.
i have a home lab network that is connected to my internet. I basically have a linksys router connected to cable modem and in order for my families internet to not go down while testing and learning my CCNA I am trying to treat the Linksys as the ISP.
1. Plugged my 891W router via FASTETHERNET 8 (192.168.1.10) into LAN Switch port 1 of my Linksys E4200 home router(192.168.1.1).
2. I plugged my 891W Gigabit 0 (10.10.10.1) LAN side into my 2950 Catalyst Switch (10.10.10.5 - VLAN 1)
3. my 2950 Catalyst switch (10.10.10.5 - Vlan 1) is plugged into my 2600 series router via the routers FE port (10.10.10.2).
There is a few more routers connected behind r2 but I am not dealing with them right now and there is also a switch connected into s1 but its not being used for this.
891w is labled r1 2950 is labled s1 2600 is labeled r2

I can ping all over my homelab everything I can reach as long as I have a protocol up but I cannot reach the WAN IPs. I watched video by Jeremy Ciorara and I tried to follow the wan and nat part from a website [URL] And none of its working. I am not sure if this is a case where a private IP cannot function as a ISP and I am breaking some rule thats not mentioned in CCNA studies or if its something else. I tried these commands from Jeremy Video:
r1(config)#ip access-list standard "NAT_ADDRESSES" r1(config-std-nacl)#permit any r1(config)ip nat inside source list NAT_ADDRESSES interface fastEthernet 8 overload
However they did not work it was pretty close to whats in the basic website up there I listed as well. I think I went back to the basic configuration in the config file post above. Its really frustrating as I follow directions and they do not seem to work. I understand I am using my private 192.168.1.0 subnet as an ISP and maybe that has something to do with it but when yoru first learning and things dont work its kind of overwelming as you have problems seeing the big picture and dont yet trust in things you have learned as they are unfamiliar so its easy to get lost.
I configured a new Asa 5505 with Ios 8.44-1-k8.bin and when I installed the Asa the client's after about 1 hour were unable to ping or map drives to the Asa. I got the following error,%ASA-2-106007: Deny inbound UDP from XXXX to XXXX due to DNS Query. I added the command same-security-traffic permit intra-interface they were then able to ping the server and connect to the Internet, but still unable to map drives i could see the connections from the Pc's to the server in a show conn with was tcp port 445 with Saa? I reverted back to Ios 8.25 and everything works.
I have been working on figuring out a VPN problem on my companies ASA5510. I was accessing the device via: ASDM, SSH using Putty, and even initially with a console cable (also using Putty) using a computer in the networking closet. All 3 of these access methods worked properly for me.I believe I may have inadvertently changed something as of Friday using ASDM. I am mostly assuming this because, as of yesterday I can no longer connect to the device. I actually cannot even communicate with it (ping the interface I normally use to manage, which I could previously ping). No computer on the same subnet as me is able to ping the interface. The device is still accepting VPN connections, dishing out DHCP addresses and everything else it normally does, but I really need to be able to gain access to it again. I am thinking to reboot the device when there is some downtime, in the hopes that ASDM doesn't save to startup-config and only to running-config.
I have installed 2 Cisco 1310's, connecting two buildings that are about 1000 yards apart. One access point is connected to an existing 3560 24 port switch, the other access point has a new 3560 24 port switch connected to it. Also installed 4 1240 access point in the newly connected building to the new switch. Issue is my router and existing switches can not ping any devices on the other side of the bridge. They can ping both access points that make the bridge. I consoled the new switch and could ping the existing switches and router, after doing that the other switches and router are now able to ping the new switch. Now my main issue is I have a user using a 7921 phone connected to one of the new 1242's, when he makes a call to a person in the first building they can hear him, however he can not hear them. Our call manager is in another state were I am located. I can call him and vise versa, and we can hear each other. I have went over my configs server times, and doubled check my IOS versions to make sure they are up to date. I will be glad to provide configs upon request.
