Debug PPP authentication should tell you what's up here.
But here is my guess...
For CHAP to work you need a username password for the local end too, you
only have it listed for the opposite router.
Since CHAP fails, you then try PAP, but you haven't specified a PAP
sent-username or PAP password. Therefore the connection comes up, but no
username is sent, therfore you are connected to "unknown," which doesn't
match the NAME field in the dialer map, so no traffic passes.
I also wonder if you are dialing back into the same router from one
end? The dial string in the dialer map is the same on both routers. If
they're supposed to call each other, at least one of them is wrong.
If you get CHAP to work, I would suggest removing the PAP. You don't need
both for this setup.
