Story so fr: 1) PPP on-demand with static IP works. 2) PPP on-demand with dynamic IP says "Host is down" on any IP request The problem is that tun driver check its READY state by *first* ifconfig address. i.e.: set ifaddr <addr> <addr2> works (static IP) and set ifaddr 0 <addr2> not works (dynamic IP) because first address is equal 0. Since tun is always POINTOPOINT interface, dst address is more meaningfull. I change checking to second (dst) address in READY test. PPP on-demand finally works.
