From: Kentaro Matsuyama <matsuy...@thinktube.com> Some PPP connections don't use a dedicated IP, instead an IP address of another local interface is "reused" on the PPP interface.
Some Internet providers require this, since their PPPoE server pushes the network address when routing multiple IPs, and some customers want to use it to save IP addresses. Reference: http://www.sustworks.com/site/ipr_guide/unnumbered.html I have added an UCI option 'unnumbered' 'INTF' which means "reuse the IP address of INTF" (e.g. unnumbered LAN will put the IP of the LAN interface on the ppp interface as well), and the following script in /etc/ppp/ip-up.d/. It works, but it is not integrated with netifd, e.g. netifd does not know about the IP address we assigned.
