Привет всем
Возможно ли сделать так:
# uname -a
FreeBSD router 6.2-RELEASE

Имеем на шлюзе 1-у сетевую карту, через неё подключаюсь к АДСЛ модему и получаю tun0 интерфейс, так же через неё подключены другие компьютеры...
Возможно ли настроить НАТ для такой схемы?
# cat /etc/pf.conf
ext_if="tun0"
int_if="vr0"
table <inat> { 192.168.106.0/24 }
set skip on lo0
nat on $ext_if from <inat> to any -> ($ext_if)
pass all

# ipfw show
00100     0        0 allow ip from any to any via lo0
65000 69410 31171206 allow ip from any to any
