can ping everything but firewall

[brianh50]

I have a laptop with xp pro. Set up configurations and could not get to internet. After checking things out I found that I can ping every node on the network(by name or address) but cannot ping our firewall. Any help would be appreciated.

Not sure about your specific firewall configuration, but many firewalls are set to not respond to pings (or any direct requests for that matter). They act as proxies, passing requests in and out of a network. They do not usually need to accept requests specifically directed to them.

Your post indicates that you don't have internet access. Is the firewall on a different network or subnet? Check your DNS, gateway settings.





Unix IS user friendly... It's just selective about who its friends are.

I have unhooked other working computers that have internet access and taken the settings from them and put them on this computer and still can't ping firewall and have no access to internet.

I always configure our firewalls to not respond to pings, yours is most likely the same?

Set "Default GateWay" section as Ip address of your firewall in the Tcp/Ip configuration, if the IP address of your laptop is not given by DHCP server. Try it, good luck....

Try the utility discussed in FAQ779-4625

Still no luck. Firewall is set up to accept pings. And can be hit from other machines. Have tried putting in other working computers network configurations into laptop. Get the same result. Network access but no internet access.

Can you check your firewall configuration. In production environment most firewalls are configured to repond and let through only specific traffic (specific users or MAC adress). The firewall will simply reject (and not respond) to any other traffic.

It is the case in my network, unauthorised user simply can't get out to the internet and won't get any kind of response when pinging the firewall. When you tried with other working computer did you use your own username or used the account of someone already logged in? Would also help to know what kind of firewall you have...ie Watchguard, Cisco or other kind.

Used complete information and configuration of user that has access( user name and password, ip-subnet-dns-gateway settings). Same result - inside network access but no internet access and cannot ping (cisco) firewall. Can take same settings and configurations put them on a different computer and i have access to everything and am able to ping firewall. MAC address not set up to be an issue with the firewall.
