i've just set up a netwotk with 2 pc's and an adsl bridge router. i've got my internet set up and everything seems ok. however, although i can access the internet, when i try to "ping" a site or ip address,i get a request timed out result.same thing happens with tracert.i can however ping the loopback address, the other pc and the router. just cannot seem to ping a remote address!any idea why this could be.

If you can ping internally, but not externally, is your firewall stopping it?

turned off windows firewall but maybe router built in firewall has something to do with it. does ping/ tracert use a specific port, which may be blocked by the router firewall?

You say you can access the Internet, so clearly your Firewall is allowing Internet traffic. What exactly are you trying to ping?

firstly let me explain why i'm trying to ping. i'm studying for network+ certification. when i had 1 pc and a usb adsl broadband connection i could ping a url or ip address and usually get the usual 4 packets sent / 4 packets received type response. since setting up the network with the adsl bridge router, i can access web pages with internet explorer. i know the internet connection is set up ok because i can browse the web. what i can't get my head around is that although i know this fact, ping is there to check network connectivity. there is a connection as i can see the web pages but cannot ping the ip address. also with tracert, just keep getting the request timed out message.

Have you actually checked your router to see if it is set to allow ping's?

For example, in my set-up it's turned off as an added security precaution. I can't remember now whether I did it, or it came configured that way, but it doesn't matter, the end result is the same and if I want to ping an address for some reason, I have to go into the router set-up pages and enable the service. In fact, I've got everything turned off, except the specific services I need.

Remember, it is a service in itself. The fact that you can access the Internet, does not mean that service is active.

Hi, can someone explain to me what "pinging" is..I am trying to figure out how to set up a network and keep seeing this "ping" stuff, should I need to do it, I have no idea what or how!!

Ping first of all, is a command. You use it in a command prompt environment.

The ping command, sends four small packets of data to the address you specify and expects four to be returned.

If you have a good connection, you will see 100% returns. Some networks with problems, may see "packets dropped" and it's a matter of interpretation as to how important that is in the context of the test being carried out.

However, if you get a "request timed out" message for each of the packets, it means you have a major problem somewhere with either the physical connection (network cards, cables etc.) or with the set-up of the network software.
