You can tell pppd to request a particular address by adding it to your options, like this: pppd 10.0.1.29: ipcp-accept-local (The ":" at the end means "request this local address, and don't insist on any particular peer address.") pppd doesn't have an automatic means to save the last-used address for a link and pick it up again. Perhaps it should have one, but you could do this in a script by having your own /etc/ppp/ip-up that stores $IPREMOTE into a file, and then pull in that file's contents for a later invocation of pppd. Note that this just tells pppd to request a particular address. There's no telling whether the peer understands what to do with such a request, or if it can or will honor it. Some servers may refuse to negotiate at all under such conditions, causing the link to fail.
