Cisco WAN :: ASA5505 Basic Configuration / No Internet Pass-through At All

Apr 8, 2012

I teach in a High School and we've got about a 300 node MS Windows Network.  Two MS2003 File Servers act as my DNS/WINS/DHCP servers. We have been using a WATCHGUARD FIREBOX III to act as the router/gateway between the outside external address and my internal ( gateway address. All p.c's inside the network are routed to one of the Servers ( or for DNS/WINS/DHCP addressing.  The servers point to for gateway.

We are trying to replace the Watchguard Firebox with a CISCO ASA 5505 (eventually we'd like to implement VPN).   When I connect the  CISCO ASA, I get no internet passthrough at all.

Cisco WAN :: 887VA-M Basic Configuration Non Nat

Jan 3, 2013

I am struggling to get this working after spending many hours looking at it I am now completely stuck. We are upgrading from a 857W to this 887 VA-M I have some experience of IOS and the 800 series. Our 857W works perfectly using almost the same config. Our situation is that the router will sit in front of our firewall and act essentially as a simple router passing everything through to our Firewall. Nat is done at the Firewall.
We currently have the following configuration that seems to connect the the ISP fine but I cannot connect to the vlan2 port on the switch the firewall cannot connect to he internet or route anything via the Vlan2 port no pings etc.. I am using Fast Ethernet 0 as the Vlan2 port and the rest are V LAN 1 with a local network address to allow me to connect a laptop.
We have a block of static IP addresses, the base of which is assigned to the V LAN 2 interface and used by Dialer 0 as IP Unnumbered. Config below.

Cisco WAN :: 800 Series Router Basic Configuration

Sep 4, 2012

I have just bought my first non-domestic router, a CISCO 887VA-K9 which needs basic configuration to get it working.  I have a copy of the configuration guide (334 pages) and CP Express user's guide (94 pages) and have spent an hour reading but either they are missing something or my brain is too small to figure out step 1.  How to get started.  Perhaps from where to download a CP Express installation kit for Windows.
Is the only way via a terminal emulator connected via a serial port ?  Is there a graphical interface I can use ?  Are there any basic tutorials for beginners ?  This is probably the only non-domestic routrer I shall work on so I don't want to invest in a full training course.  I just need enough to plug in the ISP credentials and set up DHCP.

Cisco Firewall :: Basic DMZ Configuration On ASA 5510

May 8, 2011

creating a DMZ with my current configuration. Most of my configuration has been through the ASDM as I am still learning. I'm looking for a good tutorial through the ASDM to get me on my way. What I need to accomplish is this:
I have an internal GIS server which needs to have a constant database connection to an remote GIS Server which is already configured. I've got a separate VLAN setup on my 3750 switch which connects to the DMZ configured port on my ASA with a security level of 50. My GIS server has been placed in the DMZ VLAN which is accessible from my internal clients. I have a /30 Internet block which is being used for Internet and VPN. I have a separate /28 block that I'm assuming I'll need for the DMZ to work properly.

Cisco WAN :: Linksys E2500 - Basic Configuration Of 819 Using CP Express

Aug 12, 2012

I set up a basic Linksys E2500 with the following information and connected to the internet straight away without a problem: I have spent several hours simply trying to get this basic information into the Cisco 819 using CP Express without success, i.e. I get no internet.  Rather than show my inputs, What is the correct setup.  I am a novice so I'd rather solve this issue using CP Express just to get connected in the first instance. I have a static IP address, I connected the ethernet cable carrying the internet to the internet port of the E2500 and an ethernet cable from one of the ethernet ports of the E2500 to my PC.  For the 819, I connected the internet cable to the GE WAN 0 port and the PC to one of the FE ports.

Cisco Switching/Routing :: 3750X - Basic Configuration

Jul 19, 2012

We currently have 7 Cisco 3524-XL switches (10-12+ yrs old) which are 10/100.  We purchased a handful of Cisco 3750X switches to replace them going with the whole stackwise and redundant power supplies.  Our current configuration on the old 3524 switches is that they have hardset all the ports on them to 100MB/FULL since devices would auto-neg to 100/Half. Since we're going from 10/100 to 10/100/1000 switches, I want things to auto-neg as I have heard in the past and experienced that things work better when it auto-neg to gigabit.  My upper management is afraid since the old switches wouldn't auto-neg correctly that we should hard set all the ports on the new switches, which would be a nightmare since some ports would be hard set to 100/FULL others to 1000/FULL, etc..  We've tested just about all of our devices at auto with the switches and they've all auto-neg to the correct speed. In short, is Auto-Negotiation the way to go with the newer switches or is it still better practice to hard set your ports?

Cisco WAN :: 2600 With IOS 12.3 / Basic Configuration To Allow Traffic Between Two LANs?

Dec 16, 2011

I have a Cisco 2600 with IOS 12.3.  I need a very basic configuration to allow traffic between two LANs. To test this I cleared the router config to the factory default state and configured my network addresses on the interfaces.
When I connected a PC to each interface I found they could ping each other, I was expecting to have to write ACLs to permit the traffic into the interfaces, thinking that the default behaviour of the router would be to deny access. default bahaviour without any ACLs or other routing configurations?
My config, such as it is, is as follows:  
Current configuration : 770 bytes
version 12.3
service timestamps debug datetime msec
service timestamps log datetime msec
no service password-encryption

Cisco Wireless :: 1941W Basic Configuration Required

Apr 22, 2012

I am replacing a cisco linksys router with a 1941w.
I have the 0/0 accepting a DHCP from the ISP then I have 0/1 going to a switch and hosting a dhcp server.
Where I have an issue is:
A) Finding a way to turn on the wireless and make it use the same DHCP as wired and setting up a user name/wep password
B) Turning on the GUI that is supposed to be embedded on this.
C) Finding a way to make the DNS point to the default gateway so that I don't have to set the address everytime we move the box.
Here is my current configuration, and with it I can get onto the wired network and get to the internet.
Current configuration : 4712 bytes
! No configuration change since last restart
version 15.1

Cisco Switching/Routing :: 4900M - Basic Configuration And Administration

Jan 1, 2013

First time user of cisco hardware and we just purchased the 4900m catalyst switch.  My question is very general.  I am simply hoping to network 3 servers together and I do not wish to do any fancy or advanced configuration.  Can I simply use the web management interface for network administration and setup?  I just downloaded the Catalyst 4500 Series Switch Cisco IOS software configuration guide and they talk about Cisco View network management system, is this my answer or is this what most people use for basic configuration and administration?

Cisco Firewall :: Basic ASA 5520 To Allow Access From Internet

Jan 17, 2013

I've got what is probably a very basic question - but i can't figure it out.I have: Internet (ADSL) -> 2851 (ADSL wic) -> 5520 -> internal LAN (192.168.1.x/24)
The asa has just replaced a Checkpoint firewall.I've set up the ASA to the point where all hosts on the internal LAN have internet access (using a dynamic PAT on that network).  This all works well.
The problem i have is i am trying to allow access from the internet to an internal host on a specifc TCP port (as i had done on the Checkpoint) but i'm getting:
Asymmetric NAT rules matched for forward and reverse flows; Connection for tcp src outside: dst inside: denied due to NAT reverse path failure
From what i have read i need to add a NAT exemption for this particular use case - to avoid the dynamic NAT i have setup, but im not sure how to do so.I'm running 9.1 on the ASA, no VPNs yet.  Just this basic setup.

Can't Reach Router / Internet Anymore

Sep 1, 2012

I have got a problem with my LAN connection. I can't connect to the internet anymore and I can't reach my router. I rebooted my router several times, but that didn't work. I thought my network adapter was broken, so I bought a new one and reinstalled the driver, but it did not work. My router does recognize my computer though. When I tried to boot in safe mode with network opportunities, I was able to connect with my router and internet. I can't use System Restore as I don't have any restore points.

Just got a brand new router this morning. Hooked it up to the modem, called Bright House and had it set to bridge mode, set up our wireless range extender and everything was fineMy dad's mac laptop was able to connect as well as my win7 desktop. When my brother tries to connect using his win7 laptop, though, he can connect to the router but not to the internet. He keeps getting limited access. He was able to connect and use a neighbor's wireless (but obviously we don't want to be doing that) so we know it's at least working

Cisco Wireless :: 881W - Wi-Fi User Cannot Reach Internet

Users on wireless LAN can connect to the wireless network, but cannot browse the Internet. The wifi network does not give out an ip address to the client so client cannot get to the default gateway and Internet. Not sure what part of config does not work.

Cisco :: ASA5510 Via IE On Windows Vista - Reach Router In Internet Explorer?

Jun 4, 2012

Since some days we have a ASA5510, we connected it on a Windows Vista Laptop via ethernet cable (using at the back of the router the mgtm slot) and connect it on the network slot on the laptop. Laptop is getting IP addresses automatically.
Now we tried to reach the router in the Internet Explorer using:, but we could not reach this site. When I try to ping the router via cmd and typing ping I get answers.
For us it is very important to change the IP address of the router, as he will be used in a network with addresses.

Home Network :: Cannot Reach Internet With FIOS Router From Bridged RemotePC

Dec 20, 2012

I am trying to setup a remote PC over a wireless access Point/Bridge to our FIOS router. Pic of setup is shown below. Everything is connected, there are no errors or security warnings shown in the ActionTec MI424 router. The RemotePC IP shows up as an Active Ethernet client in the Router config app. Moreover, I can run the connectivity test from the router app to the RemotePC and it passes that, and I can PING from the RemotePC to the Router. Yet I cannot reach the Internet from a Browser on the RemotePC ( I am using (2) DLINK DAP-1522 Access Point/Bridge units and they have worked as expected. I set the Router log to list any blocked IP traffic as well, and it does not show anything being blocked from the RemotePC ( So why can't I reach the Internet from the RemotePC? Seems like a gateway problem or I need to make some config changes in the Router.

Cisco WAN :: 1002 - ASR Not Doing Basic Routing

Dec 25, 2012

I have 2 sub net directly connected to a ASR 1002. This is the configuration  

interface GigabitEthernet0/0/0
ip address
negotiation auto
[Code] ....
The interface gi0/0/0 is connected directly to in another router. And the Gi0/1/1 is connected to my internal infra structure. From my router I can ping . So. I configure my PC with default-gateway (ASR).
From my PC
I can ping (gi 0/1/1)
I can ping (gi 0/0/0)
But I can not ping (the other point connected to gi0/0/0)
Why???? It is a IP inside of a sub net directly connected to the ASR. Why the ASR is not doing routing? ip routing is enable.

Cisco VPN :: ASA 5505 - Basic Web Access

Nov 27, 2011

I have a Cisco ASA5505 running the latest asdm and ios. 
[I]Cisco Adaptive Security Appliance Software Version 8.4(2) Device Manager Version 6.4(5)206[/I] 
I am trying to get basic web resolution and access but not having any luck. I just wanted to know if there is anything special that I needed to do with the ASA before I can do this. I've made a quick visio diagram of the network, see below: [URL]
The Vigor has a local sub net of 192.168.0.x/24 however there is also a "For routing use only" option. See below: {URL}. I'm hopeful that by configuring the "For routing use ip address" as one of my allocation of public ip's, that it should work okay. I can actually ping by IP and name from the interface of the ASA but can't do that or browse to websites from clients which have their default gateway set to I was under the assumption web browsing should work out of the box almost as it's treated as an outgoing connection. Here is my config for you to look at: (note, I've tried to set the route outside to the local ip of the dray tek and also the "For routing usage only" IP address). 
ASA Version 8.4(2)
hostname gilwoodasa
domain-name gilwood.local
enable password 9PvFytIZ2Vpy8Gon encrypted
passwd 2KFQnbNIdI.2KYOU encrypted
So, if you're still reading this - all I am after is a way to get basic web browsing working. Here are the logs which show the attempted web access. [URL]
