This is currently not possible using the PPPoE interface type in UCI, as the ifname configuration variable is 'abused' to point to the nic used for PPPoE.

The address is still reset everytime pppd with pppoe-plugin is started, and the dependency of both, PPPoE and the IPv4-interface on the Ethernet nic to be up is not modelled at all, i.e. assuming that 'modem' is the IPv4 interface and 'wan' is the PPPoE interface, ifdown modem will kill wan... > It's not difficult to do this as a hack by just setting the IPv4 of the interface *after* pppd came up.

I aggree. There are a couple of tickets that raise this issue https://dev.openwrt.org/ticket/1430 I have a had an attempt to resolve it myself so that I can build the interface that I require eth0.0 (10.0.0.1) | +---ppoe (dhcp) | +---gre (192.168.100.1) but I have not been able to put together a generic solution that can be submitted Cheers ---------------------------------------------------------- Chris Martin m: +61 419 812 371 ----------------------------------------------------------
