Cisco Switching/Routing :: 4.2.2 Unable To Ping 1 Internet Site From Edge Router Able To Ping
Jan 18, 2013
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.
I am trying to set up a site to site ipsec connection. AT site A, I have Vlan's 652-10.55.216.0/24, Vlan653 -10.55.217.0/24, Vlan 654-10.55.217.0/24 and Vlan655-10.55.219.0/24 and at site B, Vlan650-10.55.214.0/24 and Vlan651-10.55.215.0/24.The problem is that I am unable to get any associations when i do a "sh crypto isakmp sa"/"sh crypto ipsec sa" on either router at each site.I am also unable to ping by pluging in a laptop into the site at each site. Laptop at site A is set to access vlan 655 and laptop at site B is set to acess vlan 651. I can ping all the devices from one end to the other.I have turned on debug crypto isakmp, debug crypto ipsec, debug crypto ipsec errors but dont get anything at all as output.I have attached the sh run for each router Cisco (1941/K9) and switch (Catalyst 3750) at each site.
I have router connected to 2 3550 switches directly. 3550A and B switches are running HSRP. OSPF is running between Router and 2 switches.
From Switch B i can ping the Router Wan interface but not the internet sites. from Switch A i can ping any sites?
Switch B 3550SMIB# sh ip routeCodes: C - connected, S - static, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1
I have two Cisco routers - 2911 in HQ and RV180 in branch office. Because in HQ LAN network I have some development servers, to which guys from branch office need to have acces, I decided to setup VPN site-to-site between HQ and branch office. Everything went quite smoothly, on both devices I see, that ipsec connection is established. Unfortunately I am not able to ping resources from one network to other one and vice versa. Below is the configuration of 2911 router (I skipped som unimportant (imho) configuration directives) :
I am unable to ping any device on the internal lan from the opposite side of the tunnel. However, the tunnel connects successfully. I have the firewall disabled on both routers. Site A is using 192.168.3.1 and Site B is using 192.168.4.1. Any thoughts on why I cant ping one router from the other?
I have a new 3560G to set up a small network for a remote site. I configured the vlan and an SVI as the gateway. The switch is also the DHCP server for the LAN. I configured Gi0/2 as L3 port, connecting to the nearest neighbor. My network runs EIGRP so i advertised the routes into the EIGRP process. The switch forms EIGRP neighbors and learns all routes in the enterprise network. The problems I'm having now are: 1. The switch learns all routes in my enterprise LAN and can ping devices in the enterprise LAN, but I can’t ping any interface on the switch from the enterprise LAN. 2.
I set this up and I can ping all the gateways but never the hosts. I was hoping I could make these links between 6500's a mix of L2 and L3. Check it out. They are connected in a linear fashion R1--->R2--->R3. I can ping from R1 to R3's SVI4 gateway but I can never ping a host on that SVI4. I was hoping that I could use the port-channels between 6500's as routed links or as trunk links depending on the type of traffic....thought it would ease the migration. I suppose I could always get rid of the port-channels and just make separate L2 and L3 links between the 6500's.
I am just setting up a simple scenario with a 1841. Server @ 172.31.1.1 cannot ping 172.31.0.254 or 172.31.0.105. It can ping 172.31.1.250. The router can, on the other hand, ping devices on both networks. This is just for testing routing theory so I don't know why hosts on either side of the network cannot ping each other.
I am only using the FastEthernet interfaces on Router 1841.
The DNS comes request timed out while pinging and i am unable to browse. But the Same LAN cable is working fine in another pc. I can ping the Gate way. But not able to ping DNS.Local Network is working fine.
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 just barely put in a Cisco 3925 on our network. I've configured gigabitethernet 0/2 to live on our management VLAN with an IP address of 10.129.0.31/16. I did a "no shut" on the interface. Everything should be ready to allow me to ping and/or SSH to that interface but I can't. It's really weird because I've done this a thousand times (at least on ASAs). I must be missing something. At any rate, the default gateway of the management VLAN is 10.129.0.1. I can ping that from the router. I can also ping that from my laptop (which lives on a completely different VLAN). But I can't ping the router from my laptop or vice versa.

I have a vlan defined in FWSM for server farm there is a one server with two IP addresses and teaming has done on it how ever from FWSM i am able to ping both IP addresses but from core 6509 switch i am only able to ping one ip address. from FWSM show ARP command displays the same virtual mac addresses against both IPS of the same server.
I cannot ping and end node on my system from my Cisco 2911. I've tried to configure my computer to ping the device and I am able to. It seems the difference between using my computer and the 2911 is that with my computer I am able to set the default gateway as the end node's ip.
i have a device connected to 2960 switch. It is an access port and i could ping the device from other switches , also from outside the lan. But i am not able to ping the device from 2960 switch alone. I suspected and checked the arp table and it was showing as incomplete. I created the manual arp entry and tried pinging but no luck.
Yesterday I configured the 7010 Nexus switch. I created a VDC and allocated few ports and configured VLAN for testing. After enabling feature interface-vlan i was allowed to configured L3 interface for the vlan. I assigned ip address and connected few server to check the reachability but it says Destination Host Unreachable.
I've got a 2621 configured as my main gateway to the internet - right now it's obtaining a DHCP ip from a the ISP's proprietary router set to bridged mode.
As of now, I'm unable to ping the internal interface of the router. I can ping external IP's only, even though I have DNS servers listed, i am unable to resolve host names. I'm running a few servers to which people are able to connect to my web server, among other services. I even have a crypto map setup to another 2621 across the country and can ping all internal ips on the other end... I JUST CANNOT PING THE INTERNAL INTERFACE of the router!!
I've noticed that when I ping the router during it's boot process (using linux un-interupted) I get a response in a very short window, then dies again. I'll post my config below:
I have just setup the 3G Wifi Router (Huawei 3G21WE) for my company at remote site for temporary use.Now we want to monitor the DVR and cameras installed on the site from head office but i am unable to do it.I have done the port forwarding on the router and using Dyn DNS and configured it correctly, but i cannot browse it from internet.I have also noticed that i am unable to ping the public IP/DynDNS from internet. also i cannot find any option to disable the firewall on my router.
IP routing is disabled on the 3750 (it's acting solely as a switch) IP routing is enabled with an EIGRP process running on the 3550 router that has the network for the 3005 broadcasting.
I can ping the vpn 3005 concentrator from a telnet session in the 3550 but not from the 3750.I can ping between the 3750 and the 3550 vlan management interfaces. Visually speaking it's like this
I know this because I tracerout to the 3005 from the 3750 and it resolved the default gateway configured for the 3550 properly but then started timing out.
The 3750 is trunked to the 3550.
3750 is vtp client mode 3550 is vtp server mode
I'm wondering if there's a layer 2 issue involved here as it is a VTP domain and maybe it's not returning properly.
Here is my Lab Setup: 2691 is BGP nei to R4 router and they are not directly connected. 2691 and R4 are in same AS 6500. 2691 Config---router ospf 1 network 3.3.3.3 0.0.0.0 area 0 . Its advertising its loop back IP to OSPF domain.
We can see that 2691 and R4 are BGP neis and 2691 has 200.1.x.x routes in its route table. My question is why from 2691 router i am unable to ping any route learned by BGP from R4?

I have two Cisco ASA routers and I have a site to site vpn set up between the two. The VPN link works but Site A can't ping anything on Site B. Site B can ping Site A. Site B can ping other pcs on it's own network. Site A has been in place for a while and has other site to site VPNs that work fine, so I think the problem is with Site B. Here is the config for Site B:
cisco products and am struggling getting a VPN going between an ASA 5505 and 5510. I have a VPN created (using the VPN wizward on both) and it shows the VPN is up, but I can't ping the remote site (from either side).
On the Linksys E4200, the Internet wired connection side, I gave static IP address which is in the same network range as that of LAP2.When tried to ping from LAP1 to LAP2, ping doesnot happen. Any settings by which I can ping from LAP1 to LAP2.
1)Configured 3550 as layer 3 switch and create a default route to 192.168.2.254
2) Configured 2 static routes(for 2 vlan range traffic) and one default route to 192.168.3.254
3) ip pass through is not configured yet, still the public ip is configured at the isp router
1811 static route configs ------------------------------------ Ip route 0.0.0.0 0.0.0.0 192.168.3.254 Ip route 192.168.1.0 255.255.255.0 192.168.2.1 Ip route 10.0.1.0 255.255.255.0 192.168.2.1 3550 static route config -------------------------------------- Ip route 0.0.0.0 0.0.0.0 192.168.2.254
Testing results 1)All lan communications are working fine(inter vlan also), ping to all servers from router is getting and ping to outside public ips are getting from router,but not getting ping from switch 3550 to 192.168.3.254 and any of the public ips(internet).
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.
I have the following VPN site-2-site configuration.The trouble I'm having is host 172.168.88.3 in site A is not able to ping 172.168.200.3 in site B and visa versa. Think I have added the static routes and ACLs correctly on the 3560 switches (acting as gateways) and both PIX's to access the internal networks. Host 172.168.9.3 can ping 172.168.200.3 fine.
I have a very basic lab site to site vpn setup where I have a ASA 5505 running v7.2(4) on one side and a cisco 2811 on the other side.
What's my issue?
I can't seem to ping from cisco router to the 'inside' network of ASA (see config below) and can't seem to ping from ASA packets leaving the 'inside' interface to cisco router even w/ an ICMP ACL permit outside in. However I'm able to ping within ASA inside network & ping cisco 2811 side w/ packets leaving ASA 'outside' interface just fine.
example: ------- ciscoasa# ping inside 10.20.20.1 (to cisco loopback1 from ASA inside) Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 10.20.20.1, timeout is 2 seconds: [Code].....
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:
0/0 DHCP 10.X.X.X 0/1 192x.x.x Static 75.X.X.X no ip dhcp use vrf connected ip dhcp excluded-address 192.X.X.1 ip dhcp excluded-address 192.X.X.2 ip dhcp pool CLIENT
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 setup 5505 ASA for Testing purposes. It has static route to layer 3 switch on outside interface that goes to the internet.

I have a netger router/moden connected to my phone line for broadband, an ethernet cable coming out of that to a netgear switch an then a cable going from the switch to fa4 on the 861. I can ping the netgear router from the 861, however, when I connect my PC to it, I am unable to ping let alone connect to the internet, the PC is getting an IP from the 861 and I can ping the fa4 interface from the pc. I just don't understand my I can not ping the broadband router, I even added a static route to the netgear with no luck.
I've 3 Cisco 800 series routers and I needed to configure site-to-site vpn tunnel from branch2 to the main office(branch 1 VPN was already configured and working). I've managed to get the tunnel up and everything seemed OK as sh cry isa sa,sh cry session and sh cry ipsec sa didn't seem to have any problems.
Although the tunnel is up, I cannot ping PC-s on either side of the vpn tunnel.
