谁有配置FreeBSD上多条ADSL拨号的经验？

lhm_3000

我用freebsd6.2做双adsl网关,两条pppoe拨号只能有一条获得ip地址,另外一条获不了ip地址,但有tun设备号,请看:
fxp5: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500

# A PPPoE (PPP over Ethernet) setup may look like this:

set mtu 1480
set speed sync
disable acfcomp protocomp
deny acfcomp
set authname test1
set authkey test321

以前用openbsd4.1,差不多的设置,可以同时拨号,并获得ip地址的;为什么freebsd不行呢?
我是用ppp命令进行拨号的:
ppp -unit 0 -auto  ppp0(第一条)
ppp -unit 1 -auto  ppp1(第二条)
