You're right. The reason there's two programs (natd & ppp) that use the
alias stuff is because of the possibility of an IP number change with
ppp. At some point I'd like to just have natd, and maybe have ppp
cooperating with it to say "re-evaluate the IP number for tun0 now".
Maybe even just have natd provide a local socket mechanism like ppp.
Not for a while yet.... I'm still trying to rebuild my machine after
the loss of a 4Gb disk :(
