Cisco Switching/Routing :: 1841 - Unable To Ping Remote Gateway Or Hosts On Other Side Of Router
May 30, 2012
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.

I have recently bought two 1800 cisco routers and have tried to connect them over wan serial link, but I am having problems when trying to access resources on the other side. I am a newbie to cisco and I wonder if the problem is with the configuration or the new routers or the serial link between the sites. Below is the show-running config results I have done on both routers; I can ping the serial interfaces from both sides and remotely, but I can't ping hosts or FE from other side.

I have a central office and two branch offices, these offices are connected by a private routing service that has no connection to the Internet, the telecommunications operator in each office installs a router with a LAN and a WAN IP and configuration of these devices cannot be changed except the LAN IP. Only the central office network that is 192.168.0.0 have a router that has internet access. Remote offices have no access to the internet, what is needed is that remote offices can access the internet using ADSL router 192.168.0.254 at the central office. There are a small devices in each remote office that must connect to the internet and do not support any configuration except IP, mask and gateway, for example you cannot add a static route. Currently the pc's at remote offices has IP communication with the server from the central office using a static route. put some VPN routers between each LAN and the operator's routers (where RT yellow star appears in the diagram) and put the hosts of the two branch offices same IP range that the central office network? I had thought to use RSV400 routers?

I am using Linksys E4200 wireless router. I connected two machines, this way.
|LAP1|--------(LAN ethernet connection)----------|LinksysE4200|-------(Internet wired connection)--------|LAP2|
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.

I've got a new E4200 router, Everything works just fine, but I'm unable to ping any WiFi hosts from my LAN, I can ping LAN from any WiFi Host.If I disable NAT on the E4200 I'm able to ping WiFi hosts but then all WiFi Hosts are unable to talk to the LAN.
LAN - 192.9.209.0
WiFi - 172.16.1.0
Same config runs perfect on my WRTG54GL.

I've set up a simple lab network of two cisco routers 2611XM and to each router I've attached a computer (host). I have set up a dhcp ip addresses for each host. I've set up a correct routing as well on each router. There are 3 networks: 192.168.1.0/24 192.168.2.0/24 192.168.3.0/24 The first network between the first host and first router, second is between two routers and third is between the second router and second host. If I use first host (192.168.1.20) I can ping to any ip address (192.168.1.1 (router 1), 192.168.2.1 (router 1), 192.168.2.2 (router 2), 192.168.3.1 (router 2)) except the second host ip address which is 192.168.3.20. When I sit on the second host (192.168.3.20) i can ping to 192.168.1.1 (router 1), 192.168.2.1 (router 1), 192.168.2.2 (router 2), 192.168.3.1 (router 2) but i can't ping to the first host which is 192.168.1.20. I've even tried with attaching a switch to a router and assign it an ip address of 192.168.1.3 and the ping was echoing to it.

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 have a BEFSR41 (wired) router. On the LAN side, I'm using all static IPs, and have the local DHCP server turned off. On the WAN side, I'm using DHCP. When I plug my laptop (which runs Windows 7, and has a static IP set up) into the router, sometimes I can't connect to any hosts on the WAN side, even though other machines on the LAN side can connect to hosts outside. If I run Wireshark, I see the following happening over and over. [code] When this occurs, the laptop can nevertheless connect to the embedded web server running on the router, and, there, I can tell the router to release and renew its WAN-side DHCP lease.

I'm trying to configure an IPSEC VPN + tunnel for multicast data. When the default gateway is set on the router (1841) it works fine but if I only set a route to the IPSEC peer via our gateway then the tunnel fails to come up. The end point is to a 3rd party. [code]
I found that if I add a static route for the tunnel destination via fa0/0, the public facing interface, the tunnel comes up..ip route 10.23.4.2 255. 255. 255. 255 FastEthernet0/0
and I can then ping the tunnel IP at the far end - 10.23.0.5.Why would that be? Is there a better way to do this without using a default route??

Our company has a Cisco 1841 router which provides our connection to the outside world. We also have a windows server which provides our DHCP and DNS services. Our workstations which also get their lease from the server (using DHCP) do have a connection to the outside world.
when we connect a new computer or other device to the network we can only ping as far as the inside interface of the router. But when we assign the ip settings staticly we do get a connection, even if we configure it with the exact same ip as a lease it got a few seconds ago.

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 an GRE Tunnel across my head office and remote site with multiple subnets using cisco 1841 routers.I can ping most of the devices on the remote side, but I can not ping certain devices.These devices respond to ping requests on the local LAN, but not through the WAN link. If I change the IP of device than it start responding. I am using same gateway and mask on these devices.The remote site is running classic STP on switches with distribution switch being the root bridge.

I recently purchased a RV110W wireless router for a client. I am having issues with the VPN access. Here is the client's access log:
2012/04/17 10:59:41 [STATUS]Disconnecting...2012/04/17 10:59:47 [STATUS]Success to disconnect.2012/04/17 11:00:03 [STATUS]OS Version: Windows XP2012/04/17 11:00:03 [STATUS]Windows Firewall is OFF2012/04/17 11:00:04 [STATUS]One network interface
[Code].....
I've called Cisco tech support but the answer is disregard the log message and everything is working, and that I have a configuration issue on my end.

This would probably sound like a stupid question but it took at least 2 hours of my time so far. I have a 3750 switch where a router and a server is connected. From the switch I can ping the router and server with no issue (directely connected). But from the server I am not able to ping the router. The router and the server are in the same subnet. The router is configured as the default router for the server. I am not able to ping the server from the router either. Here's the output of the ip route from the router. The server IP address is 10.1.200.21 and the router IP address is 10.10.200.1
10.0.0.0/8 is variably subnetted, 8 subnets, 3 masks
C 10.1.30.0/24 is directly connected, FastEthernet0/0.30
C 10.1.20.0/24 is directly connected, FastEthernet0/0.20

I have an ASA that houses 11 VLANs, and I am trying to add a 12th.One of the VLANs is for PCs that have internet only access.The new VLAN will be similar, but for multifunction printers only.VLAN 99 is for internet only and works fine, I can ping the gateway of 10.99.3.33 from any PC in that VLAN.I am creating VLAN 98, modeling it after VLAN 99, and I cannot get a PC in the vlan to ping the gateway of10.98.3.17.Both switch and ASA show the new VLAN 98 as UP, switchport is UP/UP.I have deleted and recreated VLAN 98 a few times, but I cannot get a PC VLAN 98 connectivity.Once it is working on the core switch, I will add it to the trunk to the IDS switches. VTP is not in use, everything is manual. [code]

I replace our aging rv082 routers with wireless rv220w routers. The gateway to gateway vpn works great, however I am no longer able to manage our print servers port 80 management page. I can ping any host with success, and I can manage hosts that have a port 10000 or 8000 web interface - but no port 80 ones... I had no issues when using the old rv082 routers...

I have a 3560G and an ASA FW, for which I am trying to use PBR to append the next hop. The gateway is the switch VLAN address and the amended net hop is the same VLAN interface on the ASA. Trouble is, I can ping the FW from a client, but not the switch. If I remove the route map, I can ping both. Even more strange is this is the case for some VLANs, but not all!
Config:
HOST ON VLAN 96
IP 10.11.120.99
S/M 255.255.255.240

We have two ASA5510s, each with outside interfaces to the same two ISPs (different IP addresses within the same subnet, of course). Both ASAs allow ICMP on all (inside and outside) interfaces. One ASA's default route is to ISP-1 and the other is to ISP-2. We can ping the default gateways for both ISPs from only one ASA. From the other ASA, we can only ping the default gateway for the default route but not the other. The pings originate from an inside client, first configured with the default gateway for ASA-1, then for ASA-2. Why does this happen, how do I troubleshoot something like this and how do I fix it?

We have a VPN setup between two Cisco RV082 routers, the VPN status shows as connected however I can't ping the other network. I am unable to ping between routers, let alone ping computers behind those routers.
We have 2 branches, branch 1 is on a static IP and branch 2 is Dynamic. I am able to connect via QuickVPN from Branch 2 to Branch 1 and remote desktop to computers, however have yet to VPN/remote desktop in the opposite direction.
To me it seems like a firewall issue at branch 2, but what's causing this. Also they are currently running 2 differnet firmware version not sure if this would cause a problem.

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 purchased this router a few days after its release, and I was very impressed with its functions. I came from a DD-WRT flashed router with all the bells and whistles, and the E4200 lacked some features but I felt it was a fare trade off for the GHz & dual band.All was well with all my settings (quite a few to name QOS,forwarded, etc)I also updated the firmware when it came available and re entered same settings.
Approx 3 months after use I had 0 WAN connection via eth0 or WIFI, when I logged into router I was pulling a Public IP from my ISP. I could ping from inside the router but no connection on any hosts, very strange. Powercycling Modem/Router yielded same results.. I then backed up my vast amount of settings, and did a 30/30/30 reset.. With no configs I had no issue browsing on any host on my network. So I restored from backup and the issue was back again..So I did another 30/30/30 reset. Then went and reentered the exact same settings as before and the issue was gone.
