Cisco Switching/Routing :: 871 VPN Server Unable To Ping LAN
Nov 12, 2012
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 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.

The setup I currently have is a server attached via an etherchannel to a 3560x switch, which is connected to a pair of 5548UP's that are connected via vpc. The 5548's both have a single connection to 6500 series switch that does the layer 3 routing, the ports that connect the 5548 to the 6504 are trunk ports. The problem that I am having is that one of the 5548's can ping the server that is connected down stream while the other 5548 can't. While the local switch can ping the server, and other servers on the same switch in the same vlan can ping it as well. The vlan interface I am pinging from on each switch is on the same subnet as the server I am trying to ping. One other thing, Nexus #1 which can ping the sever has the mac address in its mac address table, while Nexus #2 doesn't. However I added the static mac entry to Nexus #2 and that did not allow me ping either.

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.
NX OS Ver : n7000-s1-dk9.5.2.4.bin

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 the switch ============>>>>>
sw2960g============server linux
As u see above , the inetrface Gi0/6 , Gi0/7 are connected directly to linux server by two redundent links .
I mean that Gi0/6 is connected to interface0 in linux server
and Gi0/7 is connect to interface interface1 in linux server
Gi0/6===>vlan 1
Gi0/7===>vlan 2
each interface of linux server has a different ip and different gateway .
Now from switch, I make ping to interface 0 of linux server and i have a reply , every thing is ok but when i type the command :
#sh mac address-table | i Gi0/6
There is no Mac addresses and seems no Mac address relative to Gi0/6, I mean that doesn't it mandatorty to learn the mac address of linux server and write in mac table relative beside interface Gi0/6 ? How I could ping the server but no mac beside Gi0/6 ?

The network is set up like this.
Host -----> 3750 (classic) running IPSERVICES stack ----> 3550 router -----> VPN 3005 Concentrator.
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
3750 ------> 3550 [Success!!!!]
3550 ------> VPN 3005 Concentrator [Success!!!!]
3750 ------> 3550 --xxxx--> VPN 3005 Concentrator [Timeout....]
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.

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.

This isn't a big deal as the rest of the ACL works fine, but this is an annoynace since the web auth redirects to our company website (internal for now) after successful login.We have a Cisco WLC that provides access to our production and guest wireless environments. The guest environment of course is in a separate vlan (10.10.50.0/24). So I created this ACL:
access-list 107 permit udp any host 10.10.2.13 eq bootpc <----internal DHCP server
access-list 107 permit udp any host 10.10.2.13 eq bootps
access-list 107 deny ip any 10.10.0.0 0.0.255.255 <---all internal networks
access-list 107 deny ip any 172.28.16.0 0.0.0.255 <----DR Network
access-list 107 permit ip any any
int vlan 50
Desc "Guest wireless network"
ip access-group 107 in
This ACL basically gives the wireless guests access to an internal DHCP server and full access to the internet. For the 10.10.50.0/24 scope, the DHCP server assigns Internet DNS servers and my rationale is that wireless clients would access it via the external IP address but I suppose it doesn't work quite like that with the website being behind the same router as the client machines.

I have a Nexus 5548 installed (layer 2 device only) with several 10G ports supporting IBM P770 systems and a TSM (Tivoli Storage Manager) system on a single VLAN. All of the Nexus 5548 ports are configured for jumbo frames. I was ask to install a new server on the same VLAN as the others but as 1G port without jumbo frames to allow communications with the TSM server. I'm assuming that the 1G port for this new server without jumbo frames configured on the Nexus 5548 will not be unable to communicate with the TSM server that is on the same VLAN with it's Nexus 5548 10G port configure using jumbo frames.

I am having trouble trying to configure my cisco 2509 cisco router for access server. I have two guides shown below: URL and URL
However I am running into some problems. I can go through the second guide up until it asks me to do this command
Step 5: Configure the transport input protocol on the async lines to Telnet.
Access_Server(config-line)#transport input telnet
I cannot put in Transport Input, I only have the option of doing Transport Output let me show some lines from my console:
---------------------------
Access_Server(config)#line 0 14Access_Server(config-line)#no execAccess_Server(config-line)#transport input ?% Unrecognized commandAccess_Server(config-line)#transport ? output Define which protocols to use for outgoing connections preferred Specify the preferred protocol to use
Access_Server(config-line)#transport
------------------------
Im not sure whats going on. I have two routers(cisco 2600 series) plus my 2509 cisco router I am going to use for a access server. I have a two switches 2950 series and I have the access server connected to all of them via a octal cable.
Here is the configuration from the access server:

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 a set-up with multiple C2960 and C3750 switches. All these devices are being managed remotely. So basically I login to C2901, which is used as a Terminal Server, and reverse SSH to the console of each device. That's - I have assigned an IP to each port of the terminal server so that I can SSH directly to the desired device through via the mapped IP.
Now, recently I had to restart couple of switches - one C2960 and C3750. I initiated the reboot via console connection remotely. I could see the device logs for some time and then the logs stopped and there was no reaction from the console irrespective of any command I tried to enter.
I tried resetting the line on the terminal server, but that didn't work.
Now when I try to SSH the IP mapped to console of that particular device - i dont get any login prompt and there is no effect on device after giving any command. Although i can see the logs on the console session - but cant do anything.
I have a second way of connecting the device via inband- management, and checked the device config found it correct. It is same as other devices which are working correctly.
Both C3750 and C2960 are behaving exactly same - can see logs on console but see effect of even pressing enter - not getting login prompt as well.

I am using Solawinds syslog and trying to get our Cisco routers send syslogs to our syslog server. I followed the procedure on Configuring Cisco Devices to Use a Syslog Server from [URL] Our Cisco swtches are all sending syslog messages but not the routers. I compared the config with our access switches but can't seem to find the problem:
Sample router config:
service nagleno service padservice tcp-keepalives-inservice tcp-keepalives-outservice timestamps debug datetime msec localtime show-timezoneservice timestamps log datetime msec localtime show-timezoneservice password-encryption!hostname WWF-RT1boot-start-markerboot-end-marker!security authentication failure rate 10 logsecurity passwords min-length 8logging buffered 4096logging rate-limit all 10logging console critical!aaa new-model!!
[Code] .......
is there a command that prevents the router from sending the syslog to the server?

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 could not ping 8.8.8.8 and access internet after creating the VPN. Below is my setup and router configuration: [code] From the router 1941, i could ping up to 58.185.149.141 but not up to 58.185.149.140. Since i cannot ping 58.185.149.140, i suppose i cannot ping 8.8.8.8. I am sure 58.185.185.140 is there as i use another PC which is connected directed to the office network instead of through the router 1941, it could ping 58.185.149.140.For your info, the g0/1/0 is connected to the PC while g0/1 is connected to the office network.
