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=36NETMASK=24GATEWAY=25ONBOOT=yesTYPE=Ethernet电信使用第二块网卡(eth1)：DEVICE=eth1HWADDR=00:24:e8:5c:91:71IPADDR=56NETMASK=24GATEWAY=45ONBOOT=yesDHCP_HOSTNAME=F35TYPE=EthernetBOOTPROTO=nonevi

/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 /24 via 36 dev eth0 table cnc# ip route add /8 dev lo table cnc# ip route add default via 25 dev eth0 table cnc设置电信的路由表ip route add /24 via 56 dev eth1 table telip route add /8 dev lo table telip route add default via 45 dev eth1 table tel3 制定策略 让 56 的回应数据包走电信的路由表路由， 36 的回应数据包走网通的路由表路由。ip rule add from 56 table telip rule add from 36 table cnc4 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 -p5 设置静态路由表文件# vi /etc/sysconfig/static-routeseth0 net 36 netmask 24 gw 25eth1 net 56 netmask 24 gw 45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 45增加出口路由策略，客户端是网通的走网通线路，其余走电信线路。#!/bin/ship rule add to /24 table cncip rule add to /24 table cncip rule
