iptables 怎么实现ip伪装服务

cwwhy

rh8.0中找不到ipchains 但有iptables 不知道该怎么实现ip转发,我们用hub
共享上网,别的机器能ping通主机,可怎么也上不了网,可能是防火墙的原因吧

well..i just solved this fucking problem.
first, u have to change the /etc/dhcpd.conf into
　　
      subnet 192.168.1.0 netmask 255.255.255.0 {

　　range 192.168.1.2 192.168.1.4;

　　default-lease-time 86400;

　　max-lease-time 259200;

　　option subnet-mask 255.255.255.0;

　　option broadcast-address 192.168.1.255;

　　option routers 192.168.1.254;

　　option domain-name-servers 192.168.1.254;

　　}

here, assume eth0 is connect to your isp and eth1 connected to lan.

and then, type
iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
iptables -t nat -A FORWARD -i eth1 -j ACCEPT

/etc/dhcpd.conf   这个文件好像没有啊??? 喔! 明白了,我没用dhcp分配ip 地址,我用的网关设置实现的

iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -d 211.93.111.0/24 -o eth0 -j SNAT --to 211.93.111.222
