Ah, ok.  It's a class B network - that pooh-poohs my last idea :-)

Eek.  This is a problem.  If the server uses IP aliasing, then the 
client is going to see no connections from any machines beyond that 
machine.  Aliasing is *only* for the client side.

We don't need any ppp.linkup entries on the server for the client.

I'm not sure what this is.  The client side shouldn't use the -direct 
switch.

This should really have a ``delete all'' first, but it will work like 
this because you have a fixed IP number.

Ah, ok.  If you're using -auto, you don't need ppp.linkup at all on 
the client side either (and the above ppp.dialup script isn't used :-)

Does everything work when you remove the -alias switch from the 
server ?  This explains why you can't get past `mail', but I'm not 
sure if it explains why ftp doesn't work - but there's a good chance 
it does :-)
