Thanks for your reply, toddos.

Yes I am using my external IP.

And I am guessing that the calibre library "server test" is using my internal IP address, and that is why it is connecting. You say this is probably the reason my iPod is connecting as well.

But here's the problem: if I input that same address into Opera Mobile, to try to connect to my calibre server through my Asus Transformer, I immediately get the message "could not connect to remote server." So I cannot seem to connect from this device, using either the internal or external IP.

(I removed the server password, because there is a note in calibre that the password is incompatible with android, but still no difference.)
