1、 欢迎阅读本文档，希望本文档能对您有所帮助!在DNS服务器上，配置路由工作总结2009-11-03 于知音网通 电信 双线服务器 路由 配置一服务器状态网通使用第一块网卡(eth0)：DEVICE=eth0BOOTPROTO=noneHWADDR=00:24:e8:5c:91:6fIPADDR=220.249.73.236NETMASK=255.255.255.224GATEWAY=220.249.73.225ONBOOT=yesTYPE=Ethernet电信使用第二块网卡(eth1)：DEVICE=eth1HWADDR=00:24:e8:5c:91:71IPADDR=219.140.171.
2、156NETMASK=255.255.255.224GATEWAY=219.140.171.145ONBOOT=yesDHCP_HOSTNAME=F35TYPE=EthernetBOOTPROTO=nonevi /etc/sysconfig/networking/profiles/default/route-eth0GATEWAY0=220.249.73.225NETMASK0=255.255.255.224ADDRESS0=220.249.73.236vi /etc/sysconfig/networking/profiles/default/resolv.confnameserver 202
3、.103.24.68 /电信DNSnameserver 218.104.111.122 /网通DNS二配置路由表# vi /etc/iproute2/rt_tables，增加网通和电信两个路由表252 cnc251 tel设置网通的路由表# ip route add 220.249.73.0/24 via 220.249.73.236 dev eth0 table cnc# ip route add 127.0.0.0/8 dev lo table cnc# ip route add default via 220.249.73.225 dev eth0 table cnc设置电信的路由表ip
4、 route add 219.140.171.0/24 via 219.140.171.156 dev eth1 table telip route add 127.0.0.0/8 dev lo table telip route add default via 219.140.171.145 dev eth1 table tel三 制定策略 让 219.140.171.156 的回应数据包走电信的路由表路由， 220.249.73.236 的回应数据包走网通的路由表路由。ip rule add from 219.140.171.156 table telip rule add from 22
5、0.249.73.236 table cnc四 修改IP转发文件# vi /etc/sysctl.confnet.ipv4.ip_forward = 1net.ipv4.conf.default.rp_filter = 1kernel.sysrq = 0使设置生效：sysctl -p五 设置静态路由表文件# vi /etc/sysconfig/static-routeseth0 net 220.249.73.236 netmask 255.255.255.224 gw 220.249.73.225eth1 net 219.140.171.156 netmask 255.255.255.224
6、gw 219.140.171.145将从两个WAN口出去的数据包进行IP伪装masquerade# /sbin/modprobe ip_conntrack_ftp# /sbin/modprobe ip_nat_ftp# /sbin/iptables -t nat -A postrouting -o eth0 -j masquerade /防火墙# /sbin/iptables -t nat -A postrouting -o eth1 -j masquerade /防火墙设置默认网关为电信# route add default gw 219.140.171.145增加出口路由策略，客户端是网通
7、的走网通线路，其余走电信线路。#!/bin/ship rule add to 58.17.150.0/24 table cncip rule add to 58.17.161.0/24 table cncip rule add to 58.17.180.0/24 table cncip rule add to 58.17.186.0/24 table cncip rule add to 58.18.0.0/16 table cncip rule add to 58.20.0.0/16 table cncip rule add to 58.21.0.0/16 table cncip rule a
