True, but I don't think it's necessary because it's already been shown that
his YDL box answers web page requests on port 80 at least. I'm assuming,
Cam, that the router is doing NAT and translating the IP addresses to those
on the inside. Your tcpdump shows the IP packet destination addresses as
internal so you know the firewall is correctly NATing. It also shows it
going to port "http" which is port 80. Your apache server better have been
listening on port 80 then or it would have been vociferously silent.

Let's go back to first principles....

What is the default route on your YDL machine? And is that the same IP
address as the internal interface address on your router?
