constant tun interface

[Lev Klimin]

Hello!

I have little trouble. I have 4.10-release with ppp ant ipnat. On
startup ipnat reload it's rules with interface tun0 in statments which
is ppp's device. But before running ppp, there is no tun device in
system
[8:48:04][~]:garbage# ifconfig
fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 195.161.208.151 netmask 0xffffffc0 broadcast 195.161.208.191
        ether 00:a0:c9:4b:09:29
        media: Ethernet 10baseT/UTP <full-duplex>
        status: active
fxp1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 172.16.0.9 netmask 0xfffffff8 broadcast 172.16.0.15
        ether 00:a0:c9:b6:59:a1
        media: Ethernet autoselect (100baseTX <full-duplex>)
        status: active
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
        inet 127.0.0.1 netmask 0xff000000 
ppp0: flags=8010<POINTOPOINT,MULTICAST> mtu 1500
faith0: flags=8002<BROADCAST,MULTICAST> mtu 1500
[8:48:09][~]:garbage# 

Because of lack of tun interface, further ipnat rules don't work. I
can reload ipnat then ppp starting, and it's OK. Can I build my
kernel to make tun interface on startup sach as ppp interface? I build
my kernel with option
pseudo-device   tun        1             #Tunnel driver (ppp(8), nos-tun(8))
but after reboot I don't see tun interface in ifconfig output.

Cat you help me?
