demand-dial links with dynamic IP numbers where the program that causes the dial bind()s to an interface address that is subsequently changed after ppp negotiation. The problem is defeated by adding negotiated addresses to the tun interface as additional alias addresses and providing a set of ``iface'' commands for managing the interface. Libalias is also required (and what a name clash!) - it happily IP-aliases the address so that the source is that of the primary (negotiated) interface and un-IP-aliases it on the way back. An ``enable iface-alias'' is done implicitly by the -alias command line switch. If -alias isn't given, iface-aliasing is disabled by default and can't be enabled 'till an ``alias enable yes'' is done. ``alias enable no'' silently disables iface-alias. So, for dynamic-IP-type-connections, running ``ppp -alias -auto blah'' will work for the first connection, although existing bindings will not survive a disconnect/connect as the TCP peer will be trying to send to the old IP address - the packets won't route. It's now a lot easier to add IPXCP to ppp with minor updates to the new iface.[ch] (if anyone ever gets 'round to it). It's also now possible to manually add interface aliases with something like ``iface add 1.2.3.4/24 5.6.7.8''. This allows multi-homed ppp links :-)
