pppoe怎么都不能上网，我的拓扑结构和其他人不一样。

古典VS金属

我用电信的，adsl，512k，freeBSd6.1，配置了ppp.conf 和 rc.conf
我的modem 的ip是 10.0.0.2 ，连接在交换机上了，我的服务器的两个网卡也连接在交换机上的，其他机器也在交换机上，可能和别人的拓扑不太一样，不知道怎么改一下 。帮忙。
配置如下：
/etc/ppp.conf     /etc/ppp/ppp.conf

default:
set log Phase Chat LCP IPCP CCP tun command
ident user-ppp VERSION (built COMPILATIONDATE)
set device PPPoE:ed1
set speed sync
set mru 1492
set mtu 1492
set ctsrts off
set timeout 60
disable lqr
add default HISADDR                    # Add a (sticky) default route
enable dns
adsl:
set authname xxxxxxx
set authkey xxxxxx
set dial
set login
set ifaddr 10.0.0.2/0 10.0.0.254/0
nat enable yes

我拨一次，就多增加一个tun
