This might actually go into Networking Basics because of the nature of the problem, but I tossed it in here because of the Cisco product involved. Long story short, I need to do some detective work to figure an apporpriate IP address for a NIC.I recently started working at a company with the ASA 5505 and I need to upgrade the software image on a bunch of them. There's already a computer set up with a TFTP server and Hyper-Terminal to do it. I'm trying to use the CLI update procedur[URL] but when I get to the beginning of the actual transfer from the TFTP, I get stuck at "Accessing" and then the connection times out with the message "Unknown Error".The only thing I can think of is that somehow the ASA is not making it all the way to the TFTP server, probably because the IP address settings on the NIC for the computer is set wrong. I say this because in the config file provided me, the ASA is given an address X.Y.Z.1, subnet mask /24 (where all the letters are constants) and the TFTP server has an addess in its software config of X.Y.Z.10 mask /24, but the NIC on the computer is set to A.B.C.105, which is an entirely different network.I need to figure out what I can make the NIC IP address so I stop getting the error. I tried a couple of different X.Y.Z.x addresses, but haven't gotten anything yet.

I use a CISCO ASA 5505 with ASA 8.3. Everything works fine, but when I type the following line I get an error message:
nat (inside,outside) source dynamic OBJ_SPECIFIC_192-168-1-0 10.1.5.5ERROR: 10.1.5.5 doesn't match an existing object or object-groupI even tried to create the missing object but it did not work. The document also explains how to use ASDM for this configuration. It seems that there an object 10.1.5.5. is created.
This is the output of "show running-config":

I have connected an ASA 5505 to an ADSL router that is able to assign the IP address and the also the DNS servers for the ISP for the outside interface. The ASA is loaded up with IOS "asa842-k8.bin"
I am using vpnclient with a hostname as oppose to an IP address to connect to a headend remote server. If I hardcode the DNS servers IPs in the "dns server-group DefaultDNS" I am able to resolve the hostname. If I then remove the IPs from the group and rely on the dhcp to assign them, when I try to resolve the name I have an error at the console "ERROR: % Invalid Hostname"

I can be connected to the internet (i.e. surfing, emailing) and suddenly loose my connection. I can then ping sites but not be able to access via IE or Firefox. I am running Windows 7 Home Premium and Norton. I have had the problem on multiple networks. I have DSL at home and connect wireless to the network. When this occurs my wired machines still work fine.

I'm having trouble getting any web browser to work/recognize my connection. I've confirmed that I am indeed connected to the internet (I know this because, for example, I have no problem at all downloading games via Steam). For some reason, though, when it comes to surfing the web using a browser it's as if I'm not connected (even Steam can't load the Store page, I can only download games via the Library).I moved an infection a week or two ago, and I suspect it altered something that is causing this issue. I did get some advice to open the browser and go to Tools>Internet Options>Connections>Lan Settings and make sure "Automatically detect settings" was checked, and "Use proxy server for your LAN" was not checked.I did this, and in fact "Use proxy server" WAS checked while Automatically detect settings" WAS NOT checked.

I'am having problems when connecting to the internet. I'am running Win7 64-bit and i have Belkin USB wireless adapter( Belkin surf N150) When i first bought the adapter it didnt connect to internet, so i though it is not working and i got it replaced. I got the same problem with the second one as well, and then i have changed the wireless mode on the device manager from: IEEE 802.11b/g/n to: IEEE 802.11b and eventually i have connected to internet without any errors, but in this mode the internet is unbelievably slow which is very slow when compared to another wireless mode where i have changed it from. So my question is why i can't connect to internet IEEE 802.11b/g/n in this mode? The weird thing is that some times it connects to internet with no error and dissconnects again in a short while. Also when the windows tries to repair it, i get this report:
Windows Network Diagnostics Publisher details

I am having Inspiron N4010 for almost an year now. I have had many troubles with this but never with internet connectivity. Last week I saw myself not being able to be connected to internet through wireless or wired network while everybody else was connected and surfing. I just thought it to be a small problem and the problem seemed resolved that very day itself on its own.
But today this computer has simply failed to get connected. it does get connected, open a page or two and then again refuses to connect. On the problem diagnoses from network sharing center, it was showing that the websites are not responding, then it started showing that DNS server was not responding while all my setting are correctly configured. I pinged gateway and it responds but on pinging some website there is no response at all. It s a problem with my laptop only as everybody else are using internet very well. I am using internet through my WiFi enabled cell phone using the same connection and router that i use for my laptop. I need an urgent solutions as I have to meet some deadlines regarding assignments.

I am trying to configure DMZ on ASA 5505, basic license. After changes I have made I cannot access Internet from DMZ. I think I am missing an access list for DMZ, but I am not sure.

I have basically started fresh, from a clean image. We bought these with the expectation that we would be able to configure them using the GUI for what we need, which up till this point doesn’t seem to be the case.I will tell you how I have this setup, I have our ADSL going to a modem acting as a bridge with a static IP supplied by the ISP. If i connect a laptop to that modem and set the static ip on the laptop, I get internet access fine.So I then connect the modem to ethernet0/0 and the laptop to ethernet 0/1 I connect to the ASDM and run the startup wizard with the following:
· Outside ip : 87.87.87.87 255.255.252.0 (this works on the lappy straight to the modem)
· Inside ip : 192.168.10.1 255.255.255.0
· No dmz

I have a 5505 ver 8.2 connected to a router with a T1 internet connection. There was a problem with the internet service and when it was resolved the ASA did not pass traffic to the internet until it was power-cycled. Unfortunately that's all the info I have, as I was not onsite and couldn't access the ASA.

I have not been having much success configuring my 5505 for Internet access, and I'm sure there are a few small things I'm missing. At times I believe I got it to the point where I could ping, but still not pass through the Internet traffic. At this point, I reset the 5505 and only changed a couple of settings. I have an external range with these characteristics: Network Address 67.139.113.16 (.17 is Gateway), SM: 255.255.255.248, available IP: 67.139.113.218 The external connection is through a T1 modem, and when I put those settings in my laptop, I can access just fine. When I went through the startup wizard in the ADSM, I maded the internal interface 10.209.0.3, subnet mask: 255.255.255.0 I selected PAT in the Wizard, but don't know if I should have, or if the NAT rules I tried to put in are fine. Eventually I want to add a Site to Site VPN to the rest of the 10.0.0.0 network, but I can't even pass the Internet through to the inside. Also, this will eventually be behind another hosted firewall, so I'm not worried about restricting access, even currently. However, I suspect the problem is that traffic is being blocked with the NAT rules or Access rules.I wish I could just disable those inherent deny rules Outside of pings to 10.209.0.3, all pings come back as request timed out.

I am trying to configure Nat on a clean ASA 5505, but can't get it to work. I ran the commands below. On the ASA I can ping the internet and inside vlan ip. On my laptop I can ping the ASA inside vlan ip, but I can't ping the outside vlan ip. From another network I can ping the ASA outside public ip. Is there an access-list that denies inside from accessing outside?
I am running version 8.4(3) and I erased the existing configuration.
ASA(config)# interface vlan 1
ASA(config-if)# ip address 10.0.0.1 255.255.255.0
ASA(config-if)# nameif inside

I have an ASA 5505 behind my internet router. i have got only one public ip configured on the router outside interface.192.168.20.0/24 subnet is configured between ASA and router and inside network is 192.168.10.0/24 (Refer the attached diagram).
I have exposed my mail server and ftp server to public through static PAT in router and ASA with the same public on router outside interface. Iam facing issue some of the machines inside my network internet is not working(actually DNS is not resolving) some of the PC's internet is working fine some of the PC's randomly working. i have attached the diagram and ASA config , after this issue is sorted out i need to configure a L2L VPN to my head office.

I have a Cisco ASA 5505 that has been configured to act as a router as well. I have configured 3 VLANS that have access to the internet. For some reason the "InsideWifi" and the "Guest" VLANS have very slow internet speeds and sometime web pages wont finish loading properly. The "Inside" VLAN gets the speeds that are expected. The DNS server does reside on the "Inside" VLAN. Is there anything wrong with my configuration that would cause the internet speeds on the other VLANS to be slow? My config is attached.

We currently use a linux software based firewall called IPCop that sits between our network and router (This is in bridged mode) IPCop conects over PPPoE and everything works fine.
However the system is not reliable and I fear not that secure so have purchased an ASA5505 now I have added the PPPoE info to the device using the ADSM software however although it picks up my external static IP I'm unable to access the internet. On IPCop I only had to enter the broadband credentials and it worked however I feel like I may have to add more to the Cisco, for example do I have to specify DNS servers and do I have to set a static route?
Here is my config file so far (Note I think I have turned on the ability to ping from internal to external). My config I have done through the ADSM as opposed to the CLI

I recently bought an ASA on eBay the plan was to try and learn how to configure them and get more familar with Cisco's ASA hardware etc.
I want it to do the routing for my home network. The way things are setup at the moment is pretty standard. I have an ADSL modem which is also a router which was provided by my ISP (Orange).
The first thing I did was change the router to be in "modem only" mode which seems to have worked. I then got the ASA to use PPPOE by following this guide [URL] I assume that worked as it is authenticating with the ISP and I'm getting a puplic IP address assigned to the outside interface. The default gateway is being set by the "ip address pppoe set route" command which I have verified with the "show route" command. The problem I'm having is that even though I'm getting a public IP I can't ping any thing from the ASA I've pinged 8.8.8.8 and 4.4.4.2 using the outside interface as the source but I'm not getting any responce. I have tried changing the MTU a few times to different amounts on the outside interface with no luck.

I set up an ASA 5505 at home through PPPOE connection. The ASA seems to obtain an IP address correctly.and I can ping a public ip address using the outside nic, but not the inside nic. I saw the error message when I ping: No route to ff0213 from fe801bc2b1288cd5bc1. As a result, I cannot connect to the Internet.
