Local Network Computers Can't Browse The Internet?
Feb 12, 2011
We have Linux server (CentOS) and nearly 120 computers in the local network (192.168.1.0 255.255.255.0) and nearly 20 computers have their own IP-address (real address). Periodically the 192-network computers can't browse the Internet; ping to the server is working; computers which have their own address are working properly

I have a E2500 connected to a cable modem as the base of my home network. Hard wire connected to the E2500 is an linksys 8 port hub and a couple of computers. The 8 port hub is connected to a couple of computers and a xbox. I have the hub as a distro point to cut down on wiring. Wirelessly connected to the E2500 are a variety of laptops, netbooks, ipods, an ipad, a playbook, an iphone, a android phone, a wireless printer and a Ps3. Most of the devices are just using the wifi for internet access. Most devices have been setup with their own ip addresses to avoid ip conflicts. The computers and laptops/netbooks are running either Windows XP, Windows 7 or Mepis Linux. Up until now everything was going as good as can be expected, all the computers could see each other and most could transfer files between each other except when Windows gets picky.In the last few days no computers can see each other. Windows or Linux.Everything can accsess the internet and wirelessly print still just can't see each other. I reset the E2500. I updated the firmware on the E2500. I installed the Cisco Connect software (just in case I was too stupid too setup a router). Still nothing. I can ping other machines from a command prompt in windows or a terminal in Linux and get a good ping back. In the router setup via a browser I can go to the status page and see other devices on the local network but most are just ipods, ipad, playbook and the wireless printer, If I go to the administration page / diagnostics I can ping other computers and get a good answer. I just can see them from each other. I think I've rebooted every thing at least once. Yes the workgroup names are all the same (workgroup) and yes file sharing is turned on on all computers.

when I ping another workstation on my local network I should get back it's local IP but instead I am getting an ip address that resolves to somewhere in Germany! In fact if I ping any bogus name, I mean anything, it returns this same address 62.116.181.25. If I shut down my cable modem then everything resolves correctly. And yes I have DNS relay enabled because it seems to be the only way to get the workstations to resolve external sites correctly.

We have two offices separated by a WAN.Office A is our main office that has all of our servers, including domain controllers and active directory, on our own network.Office B is a temp. office that is piggybacking off of our sister company's network, but the computers there still connect back to Office A servers to login/access services. However, Office B connects to the sister company's local domain controllers for DNS/WINS.We're having an issue where NetBIOS names of the other office are not always showing up when browsing for computers within the WinXP Windows Explorer (My Network Places --> Entire Network --> MS Windows Network --> domain A). It seems entirely random whether or not we can see the other office's computers. We can still ping/remote to them, but cannot browse to them.
It would normally be a non-issue, but some of our software apps require us to "Browse" to the network server location, rather than being able to type in the address, during installation. Can't install if we can't browse the Office A servers. Obviously has something to do with WINS not always populating/updating, but I'm not sure what or how to fix this.

I just installed a new ASA 5505 for an office with three internal subnets.* The three networks can each get online fine and ping eachother, but cannot browse to shares on the two internal networks other than their own.* How do I configure the ASA to allow all traffic between these three inside networks?

One of our servers recently lost its outbout network connectivity. It can ping and communiate with any computer on our LAN, but it can't communicate with anything outside our network.

the site has a private wireless network for which I pay a yearly access fee. This gives me a code I can use to gain access each time I connect. We used to be able to have all our family's laptops, etc., connected at the same time using this code, but the site has recently changed the configuration so that we can't do this. Is there any way we can share the connection made by one computer so that we can all access the Internet at the same time? The site is in a remote location that gets poor mobile data coverage and landlines are not an option. The yearly fee is already high, so I can't afford to pay for multiple subscriptions.

I can't connect to the internet. When I double click Local Area Network under Network connections it says it has both sent and received packets. It is set to automatically acquire an ip address. The computer is connected to a router. I can ping 192.168.1.1 but when I try to reach my router's settings it says page can't be loaded. I tried to hook the computer up directly to the modem and connect that way. It said it was connected and it was sending packets but I still couldn't do anything. I've turned off the windows firewall. The computer is Windows XP SP1.

I am testing a EasyVPN IPsec server set up on a cisco 891. Here is how I have it set up right now- the 891 is connected to our backup internet connection (different ISP from our main line) and we have a cisco 1921 as our production router.
I am experiencing a problem where when I am on our internal network off the 1921 and I connect to the VPN on the 891 I lose all local network connectivity. Nothing works, can't ping, can't telnet to the 1921, can't browse the internet, its not just DNS either.
I believe the issue lies in the configuration of the IPSec server on the 891 because when I connect to our client's cisco IPSec VPN I experience full local connectivity with no issues whatsoever. It seems to me that ALL traffic is being routed through the tunnel.
Other than the local issues the VPN is working fine and I can remote desktop to the PC I have set up off the 891 and telnet to the 891 from there.

What I'm trying to do is create a private network for local file sharing but also have internet access. There is a WRT54G router connected to a satellite modem in a separate building, just barely close enough to connect from my laptop, which is what sparked my original idea to use my WRT54GL as an access point.

I have a Cisco ASA 5510 I am using ASDM 6.1
I have a LAN and a DMZ and an internet connection. I am using one of the internet connection IPs to host a HTTP service on a server in my DMZ. (its the same interface as my internet connenction but a different IP to the one used for internet connectivity)
so say my LAN is 192.168.1.x
and my DMZ is 172.168.1.x
I can access DMZ from Lan and vice versa. when i try to access the public IP (or URL) from a pc in my LAN i get nothing.
I have enabled DNS rewrite (doctoring) but it is still not working. the HTTP service is available from other sites.

I configure for our office site to site VPN project. Now I configured already Site to site vpn between ASA 5510 and 1841 router.
HQ LAN
Branch LAN 10.2.1.0/24 >>> ASA 5510>>>>> 1841 >>> INTERNET <<<<<< 1841 <<<<<< 10.30.3.0/24 ^^^^ Call Manager 2851
Now can access from Branch LAN to HQ LAN each other. I face the problems that are
1) In branch LAN , they can access HQ LAN & resource , but cannot access internet. I didn't configure NAT on PH Router
2) Can I access internet from BRANCH LAN through HQ LAN to INTERNET. Or Can I access Internet from Branch LAN from PH Router directly while access to VPN to HQ LAN ?
3) In Branch Site , hard phone cannot work but soft phone on PC can call to HQ. Hard phone IP are same in Remote Network (172.16.1.0/24 ) . Is it problem ? how can I configure separately ?

I've been trying to set up my new Cisco 1921 Router to provide internet access to my local network but with no success. I've been reading guides and looking at videos and I have to be missing something becaouse I can't access internet (ping/tracert) from my local network.
The DHCP server works fine and the clients on my local network gets ip-adresses from the router but can't ping or tracert outside the local network.

I have a very annoying problem with my Linksys WRT54G2.When I connect a wireless device (laptop, phone, TV, Ipad) to my wireless network I only see a Local connection, no connection to internet. After resetting the router (power off for several seconds) the internet-connection is available again.I have to do this every 1 - 2 days.

I have a very strange problem affecting my LAN. New entrants to the network can ping successfuly but cannot browse. Rest of the pcs that have been on the network before are browsing quite fine. Even when I connect new PC directly to the router LAN ports, problem still persists. I've tried four different new laptops so far. I've even intalled a new router to no avail.

The first thing that came to mind was DNS. There's just 1 of about 50 people here who's having this issue. He can't browse to the network share (\servershare) using the hostname, but he can by IP address.I've checked the host file, looks normal. I can ping the server by hostname or IP address. And in fact, after going to \server, it shows 1 share which we deleted 2 days ago. It only shows 1 share when there's in fact about 20. This only happens when browsing to the server via hostname.If we browse by IP address, he can see all of the shares on the server.. (\192.168.x.x)

I can ping all the devices on my network but cannot browse any pc/server, mapped drives now disconnected. I can access the laptop from another machine and can browse the internet from the laptop. It has windows 7 ultimate. I have tried everything from forums, sfc/ scannow, flushdns, all services started.
