刚好想写教程，虽然还没有写到PPPoE+iptables，但看到你正好问到，就先写一部分。仅供参考。
我的个人网站 www.aoiday.com 教程刚刚写完4章，希望大家来补充。同时希望纠正错误。我是个初学者。
设置好网卡以后
[root@fedora ~]# adsl-setup
Welcome to the ADSL client setup. First, I will run some checks on
your system to make sure the PPPoE client is installed properly...
LOGIN NAME
Enter your Login Name (default root): XXXXXXXX ← 显示ISP提供给你的ID
INTERFACE
Enter the Ethernet interface connected to the ADSL modem
For Solaris, this is likely to be something like /dev/hme0.
For Linux, it will be ethX, where 'X' is a number.
(default eth0): eth1 ← eth1回应
Do you want the link to come up on demand, or stay up continuously?
If you want it to come up on demand, enter the idle time in seconds
after which the link should be dropped. If you want the link to
stay up permanently, enter 'no' (two letters, lower-case.)
NOTE: Demand-activated links do not interact well with dynamic IP
addresses. You may have some problems with demand-activated links.
Enter the demand value (default no): ← ENTER
DNS
Please enter the IP address of your ISP's primary DNS server.
If your ISP claims that 'the server will provide dynamic DNS addresses',
enter 'server' (all lower-case) here.
If you just press enter, I will assume you know what you are
doing and not modify your DNS setup.
Enter the DNS information here: ← ENTER
PASSWORD
Please enter your Password: ← ISP提供的接续密码
Please re-enter your Password: ← 确认键入
USERCTRL
Please enter 'yes' (two letters, lower-case.) if you want to allow
normal user to start or stop DSL connection (default yes): no ← no(仅让root进行接续操作)
FIREWALLING
Please choose the firewall rules to use. Note that these rules are
very basic. You are strongly encouraged to use a more sophisticated
firewall setup; however, these will provide basic security. If you
are running any servers on your machine, you must choose 'NONE' and
set up firewalling yourself. Otherwise, the firewall rules will deny
access to all standard servers like Web, e-mail, ftp, etc. If you
are using SSH, the rules will block outgoing SSH connections which
allocate a privileged source port.
The firewall choices are:
0 - NONE: This script will not set any firewall rules. You are responsible
for ensuring the security of your machine. You are STRONGLY
recommended to use some kind of firewall rules.
1 - STANDALONE: Appropriate for a basic stand-alone web-surfing workstation
2 - MASQUERADE: Appropriate for a machine acting as an Internet gateway
for a LAN
Choose a type of firewall (0-2): 2 ← 2回应
Start this connection at boot time
Do you want to start this connection at boot time?
Please enter no or yes (default no): ← ENTER
** Summary of what you entered **
Ethernet Interface: eth1
User name: XXXXXXXX
Activate-on-demand: No
DNS: Do not adjust
Firewalling: MASQUERADE
User Control: no
Accept these settings and adjust configuration files (y/n)? y ← 确认
Adjusting /etc/sysconfig/network-scripts/ifcfg-ppp0
Adjusting /etc/ppp/chap-secrets and /etc/ppp/pap-secrets
(But first backing it up to /etc/ppp/chap-secrets.bak)
(But first backing it up to /etc/ppp/pap-secrets.bak)
Congratulations, it should be all set up!
Type '/sbin/ifup ppp0' to bring up your xDSL link and '/sbin/ifdown ppp0'to bring it down.
Type '/sbin/adsl-status /etc/sysconfig/network-scripts/ifcfg-ppp0'to see the link status.
设定DNS
[root@fedora ~]# sed -i '/^nameserver/d' /etc/resolv.conf ← 删除旧的设定
[root@fedora ~]# echo "nameserver XXX.XXX.XXX.XXX" >> /etc/resolv.conf
← 设定为ISP提供的地址
[root@fedora ~]# echo "nameserver XXX.XXX.XXX.XXX" >> /etc/resolv.conf
← 设定为ISP提供的地址
[root@fedora ~]# cat /etc/resolv.conf | grep nameserver ← 确认
nameserver XXX.XXX.XXX.XXX
nameserver XXX.XXX.XXX.XXX
