This requires that the remote peer can correctly supply a value for it based on the identity of the caller, or on the remote address supplied by this side. Due to the way the IPCP op- tion negotiation works, this address is being supplied late during the negotiation, which might cause the remote peer to make wrong assumptions. In a similar spirit the remote address can be set to the magical value 0.0.0.1 which means that we don't care what address the remote side will use, as long as it is not 0.0.0.0. This is useful if your ISP has sever- al dial-in servers. You can of course route add something or other 0.0.0.1 and it will do exactly what you would want it to.
