在NETBSD上配置ADSL+IPF+IPNAT(轉)[@more@]

  OS: 2.x

  配置網路卡的IP地址:

  # vi /etc/ifconfig.rtk0

  inet 192.168.0.1 netmask 255.255.255.0

  # vi /etc/ifconfig.tlp0

  inet 192.168.1.2 netmask 255.255.255.0

  配置主機名:

  # vi /etc/myname

  netbsd

  # vi /etc/hosts

  127.0.0.1    localhost    netbsd

  配置DNS解析:

  # vi /etc/resolv.conf

  nameserver 202.99.160.68

  nameserver 202.99.168.8

  配置閘道器:

  # vi /etc/mygate

  192.168.0.10

  配置主機本地解析:

  # vi /etc/hosts

  192.168.0.10    win2k

  配置SSHD服務:

  # vi /etc/defaults/rc.conf

  sshd=YES

  # vi /etc/ssh/sshd_config

  PermitRootLogin yes

  安裝配置ADSL:

  # pkg_add rp-pppoe-3.5.tgz

  # mkdir /etc/ppp

  # cp /usr/pkg/share/examples/rp-pppoe/pppoe.conf /etc/ppp/pppoe.conf

  # adsl-start

  配置防火牆代理上網:

  # vi /etc/ipf.conf

  =================================/etc/ipf.conf==============================

  # +-----------+  +------------------------------+  +------------------+

  # | ADSL-Modem|---| ppp0 tlp0 NAT+IPF  rtk0 |---| Internal Network |

  # +-----------+  +------------------------------+  +------------------+

  # +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

  # Interface: all

  # Block all incoming and outgoing packets unless they're allowed later.

  # +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

  block in all

  block out all

  # Possibly dangerous: packets with ip-options, short and fragmented packets

  block in log quick on ppp0 proto icmp from any to any

  block in log quick all with short

  block in log quick all with ipopts

  block in log quick all with frag

  block in log quick all with opt lsrr

  block in log quick all with opt ssrr

  # Local network traffic is allowed

  pass out quick on lo0

  pass in quick on lo0

  pass out quick on rtk0

  pass in quick on rtk0

  # Block faked or unlikely "local" addresses

  block in log body quick on ppp0 from 192.168.0.0/16 to any

  block in log body quick on ppp0 from 172.16.0.0/12 to any

  block in log body quick on ppp0 from 10.0.0.0/8 to any

  block in log body quick on ppp0 from 0.0.0.0/8 to any

  block in log body quick on ppp0 from 127.0.0.0/8 to any

  block in log body quick on ppp0 from 169.254.0.0/16 to any

  block in log body quick on ppp0 from 224.0.0.0/3 to any

  block in log body quick on ppp0 from 204.152.64.0/23 to any

  # Blocking of outgoing faked or unlikely "internal" addresses

  block out log body quick on ppp0 from any to 192.168.0.0/16

  block out log body quick on ppp0 from any to 172.16.0.0/12

  block out log body quick on ppp0 from any to 10.0.0.0/8

  block out log body quick on ppp0 from any to 127.0.0.0/8

  block out log body quick on ppp0 from any to 0.0.0.0/8

  block out log body quick on ppp0 from any to 204.152.64.0/23

  block out log body quick on ppp0 from any to 224.0.0.0/3

  # The pass rules to enable Services

  pass in on ppp0 proto tcp from any to any port = 20 flags S keep state

  pass in on ppp0 proto tcp from any to any port = 21 flags S keep state

  pass in on ppp0 proto tcp from any to any port = 22 flags S keep state

  pass in on ppp0 proto tcp from any to any port = 25 flags S keep state

  pass in on ppp0 proto tcp from any to any port = 80 flags S keep state

  pass in on ppp0 proto tcp from any to any port = 110 flags S keep state

  pass in on ppp0 proto tcp from any to any port = 443 flags S keep state

  pass in on ppp0 proto tcp from any to any port 55000 >;< 56000 flags S keep state

  # The general pass rules.

  pass out quick on ppp0 proto tcp from any to any flags S/SAFR keep state keep frags

  pass out quick on ppp0 proto udp from any to any keep state keep frags

  pass out quick on ppp0 proto icmp from any to any keep state keep frags

  =================================/etc/ipf.conf==============================

  # vi /etc/sysctl.conf

  net.inet.ip.forwarding=1

  net.inet.tcp.mss_ifmtu=1

  # vi /etc/ipnat.conf

  map ppp0 192.168.0.0/24 ->; 0/32 proxy port ftp ftp/tcp mssclamp 1440

  map ppp0 192.168.0.0/24 ->; 0/32 portmap tcp/udp auto mssclamp 1440

  map ppp0 192.168.0.0/24 ->; 0/32 mssclamp 1440

  啟用防火牆設定:

  # vi /etc/defaults/rc.conf

  ipfilter=YES                            # uses /etc/ipf.conf

  ipnat=YES                                # uses /etc/ipnat.conf

  ipfs=YES        ipfs_flags=""        # save/load ipnat and ipf states

  ifwatchd=YES

  配置動態域名更新:

  # wget

  # tar zxvf ez-ipupdate-3.0.10.tgz

  # cd ez-ipupdate-3.0.10

  # vi conf_file.c

  增加一行:

  #include ;

  # vi ez-ipupdate.c

  註釋掉下面幾行(4515行):

  //else

  // {

  //  fprintf(stderr, "no update needed at this time ";

  // }

  # ./configure

  # make

  # make install

  設定撥號後自動執行:

  # vi /etc/ppp/ip-up

  #!/bin/sh

  /usr/local/bin/ez-ipupdate -i ppp0 -h nero.3322.org -S qdns -u llzqq:9335333

  # chmod 700 /etc/ppp/ip-up
