Cisco 2691 - Can't Ping Past Gateway

Oct 24, 2012

I've spent the last two days working on this problem and it is killing me! I know the answer has to be something simple, but despite hours of searching and trying different things, I just can't seem to fix it.Essentially, I am going to be installing a Cisco 2691 and use it as the default gateway for a small business. It will be directly connected to a cable modem with a static IP. The other Ethernet interface is going to connect to a 2950 switch with a couple different VLANs.

The problem I'm having is that I can ping anything external from the router itself. From the clients connected to the 2950, I can ping IPs in other VLANs, and I can ping up to the IP of the external interface, but no pings go beyond that.I've set up NAT overload on the router, and when I do a debug ip nat, I see the pings trying to get through with the proper translations, but I still don't receive ICMP replies back.I set up GNS3 to simulate what I'm trying to accomplish (since it emulates a 2691). Attached is a jpg of the topology -- on the right is the "simulated ISP" with 3 loopback networks and one host on a different subnet. The 2691 has a static route to the "Internet" router, and can ping everything attached to the router, including the host. The host (5.5.5.5) can also ping the outside interface of the 2691 (50.50.50.2).

However, the hosts behind the 2691 can't ping past 50.50.50.2. The 192.168.0.x network can be ignored, because that network won't need to access the Internet. But the 10.10.20.x (VLAN 20) and 10.10.30.x (VLAN 30) networks will need to. In the simulation, the hosts are 10.10.20.5 and 30.5. They can ping each other, their default gateways, and the 2691 outside interface (50.50.50.2) but not the other side, the "Internet" router at 50.50.50.1 or beyond.

Cabling / Cards :: Cat5 Not Working Past 25Ft

May 22, 2012

We are setting up a network in our new house. We have the internet entering the garage. From there we have a 60 ft Cat 5 cables run through the crawl space. Orginally we had the wireless router attached to the end of the cat 5 and then attached to the computer. We could not get a connection through this wire. We then took out the cable, and ran a new one, same issue. We took the same cable, cut it down to 25 feet, installed the router in the garage and we have an excellant connection. We then ran a new wire through the crawl space from the router. Same issue, no connectivity. Taking that cable out, cutting it down we ran the wires from the router to our computers in the garage. why a Cat5 cable would not work at 60Ft.?

Cisco WAN :: 2610 / Windows 7 Can't Ping Past Local Interface

Jul 18, 2012

Ive got my home lab setup with two 2610 routers hooked togeather with a DTE/DCE Crossover and I have OSPF configured on both routers. Each router has one 3550 switch connected to each FA0/0 inteface. The issue is that Everything can be pinged except my windows 7 PC connected to the R1 LAN. Everything else can be pinged from any other device. I checked the PC gateway configuration, disabled the firewall and checked my switch configuration! Is their something that I need to change in Windows?

Windows PC can't ping past the FA0/0 interface between the switch and R1

Cisco Switching/Routing :: 3850 System LED Blinking Fast - Not Getting Past POST?

May 14, 2013

I pulled a brand new Cisco 3850 Switch out of the box yesterday.  Following the Quick Start Guide, I put in the power module, powered it on, and waited for it to complete POST.  Then, I plugged in an Ethernet cable between a laptop and the switch on a port in the front, and went to the web interface at https://10.0.0.1.  I got to the Express Setup, and attempted to change the IP address of the switch to an IP on my LAN, along with other options.  When clicking submit, it didn't appear to take.  Upon refreshing in the Express Setup, the IP config was blank, so I once again configured it.  This time clicking submit brought up a message that it was changing the IP address.  I waited for it to finish, and when it looked done, I powered the switch off and took it to a different room to hook it up to the LAN for further configuration.
 
When plugging in the power at that point, the switch starts through the normal light process (System LED blinks green slowly), and then eventually the System LED blinks green very fast and never stops.  It doesn't get to the point of having the system loaded and ready to log into.  There's no amber lights, just the System LED flashing green fast.  On the back, the Power module and all bay lights are green, and the Console light is green, but the Management port light is off.
 
I've tried using the reset button on the back of the switch two different times to reset it to default configuration, thinking I hosed it somehow, but it never goes past the fast blinking System LED.

Cisco Firewall :: 2911 Router Zone Firewall And IP NAT Enable

Mar 20, 2013

I have a simple setup where I have a 2911 router with three interfaces, Inside, Outside and a second "Inside" interface which is labelled as a DMZ. The Zone Firewall applied to the "DMZ" is actually Inside (until I can work through problems). I need to be able to access a device on the DMZ via its external IP so I have designed NAT to use IP Nat Enable commands. This is now working for me fine. However, since utilising IP Nat Enable, my zone firewall now denies return TCP / UDP traffic and consequently I no longer have any internet access. Looking at the syslog messages, the reason for this is that the router is denying these return flows not because they are matching the outside-to-inside policy, but rather they are matching the outside-to-SELF policy. The router seems the detect that the internet traffic is being returned to SELF, when in reality the NAT rule should pick this up and forward it to inside. I can understand why this is happening, because I am NATting all private / inside traffic behind the external IP of the router, which is assigned to the Gi0/0 interface. [code]

Router / Firewall / VPN All-in-one

Jul 12, 2011

We are moving away from our managed router and firewall from our old ISP to a new one. Previously we have used older Cisco products with a separate Firewall/VPN and Router. I would like to look at some of the combined appliances. Here is what we need:

1. a Router that won't choke on fairly heavy web browsing for 70 end users.
2. a Router that can handle 10 MB of fiber.
3. A Router with a combined firewall & simple vpn for 1-2 remote users.

Cisco WAN :: 1841 BPR With Router And Firewall

Oct 20, 2012

In my company, we have two Internet connections, one for VPN and the other for emails and browsing. I have Cisco 1841 router with dual ADSL links, and also it's conntected to ASA and the other PIX. through one physical interface (vlan 1and vlan 2). The PIX firewall is connected to users, and the ASA is for VPN only.How can I seperate the traffic is going for emails and browsing and the vpn traffic. I have got to the point, that the router is configured for both ADSL connections, and I also configured the access-list and route-map in the router, the thing is when both ADSL configured together none of them works.

Cisco Firewall :: DMZ Setup Using 2811 Router

Aug 11, 2011

I am pretty new to the configuration of a DMZ and I have the task of setting one up.I have a Cisco 2811 Router running Cisco IOS Software, 2800 Software (C2800NM-ADVENTERPRISEK9-M), Version 12.4(24)T1, RELEASE SOFTWARE (fc3), 2 FE interfaces.One FE is connected to the WAN, with a loop back interface configured with the public IP for Internet access in the office.The other FE has 2 sub interfaces configured, one for data and the other for voice traffic.Users within the office are configured to use the data VLAN to access the internet through the WAN.
 
Now we are setting up some new services and we require to have DMZs setup.I want to setup 3 zones now that the different servers would reside in. How can i achieve this using the existing infrastructure I have?I have an idea to create more subinterfaces and assign them to the zones, but I am still not sure how this would play out. I have been on this for the whole day and unable to make significant progress.
