it's a problem with the network address translator. i may only be configured to translate and allow tcp and udp packets but ignore and drop other IP packets like ICMP (which is used by ping). when you shutdown NAT, any packet passes through so now you can ping the apache server (since it can also see your internal network) but cannot browse the internet because request packets are no longer translated before exiting your network.
or if your NAT is done in linux, you may have just forgotten to include kernel support for ICMP Masquerading. pong On Wed, 14 Nov 2001, lito lampitoc wrote: > Why is it when a hosted site is accessed from the "NAT"ted local > network, these public IPs cannot be seen or ping , but is only reachable > from the outside.
