求教！！！不懂pppoe拨号连接失败~~~

公司有两个linux虚拟机，在一个网段里面，一个是192.168.0.70,一个是192,168.0.72.想把70拿来做服务器端，72拿来做客户端。
我用的是ppp-2.4.4加rp-pppoe3.8版本的，两个安装都没有问题。
server端设置：
/etc/ppp/pppoe-server-options文件
# PPP options for the PPPoE server
# LIC: GPL
#require-pap
require-chap
login
lcp-echo-interval 10
lcp-echo-failure 2
ms-dns 8.8.8.8
ms-dns 8.8.4.4
/etc/ppp/chap-secrets 文件
# Secrets for authentication using CHAP
# client server secret IP addresses
####### redhat-config-network will overwrite this part!!! (begin) ##########
####### redhat-config-network will overwrite this part!!! (end) ############
"wzm" * "wzm" *

之后再终端执行以下命令：
iptables -A POSTROUTING -t nat -s 192.168.0.0/24 -o ppp0 -j MASQUERADE
echo "1" > /proc/sys/net/ipv4/ip_forward
/usr/local/sbin/pppoe-server -I 'eth0,eth1' -L 192.168.0.70 -R 192.168.0.230 -N 160 -k -d -A &


客户端设置

/etc/ppp/chap-secrets 文件
"wzm" * "wzm" *

终端查看状态
pppoe-status
pppoe-status: Link is down -- could not find interface corresponding to
pppd pid 6371

终端连接服务器端
Using interface ppp3
Connect: ppp3 <--> /dev/pts/5
LCP terminated by peer (peer refused to authenticate)
PADT: Generic-Error: RP-PPPoE: Child pppd process terminated
Modem hangup
Connection terminated.

ps:查看客户端的ifconfig

不知道为什么会多ppp1 ppp2?
