Can you define, for us, your take on internal vs. external?
The reason I ask is that if the network portion of the IP address
(the first 2 or 3 octets) doesn't match any IP address assigned to
the gateway, you won't be able to ping it. Also, the netmask has to
match, as well.
If you mean an address that's external to your in-house IP network,
then it won't ping anything inside your network, anyhow...the
external address on that gateway is almost always on the "other side"
of that gateway, meaning outside the scope of your internal network.
