Windows 2000 Server, SP 4

Machine can ping any resource inside the firewall (including the gateway) by IP or by name.

Machine can not ping anything outside by IP or name. If I ping a name, I do see the proper IP address in the ping attempt, so this does not seem to be a DNS issue.

Router is a Netscreen 10 with no restrictions on outbound traffic.

Any ideas would be greatly appreciated!

Thank you.

Therefore, you have to allow inbound IGMP traffic in order for a ping to the outside to work. Many routers exclude this type of traffic by default. You should still be able to browse external hosts because you are getting name resolution.

Hope this helps!
