Dear List
I have two servers in my net,one with a valid IP. I want to redirect all
the HTTP Traffic(external -> internal) to my internal Web server I'm
trying to learn iptables, but when I test my rules, sometimes when I try
to erase them it appears not do what I want.
Questions
1)
I use it to erase my rules. But sometimes without sucess. Bug?=20
#erasing rules=20
iptables -F
iptables -F -t nat
iptables -X
iptables -X -t nat
iptables -Z=20
iptables -Z -t nat
2)To redirect the traffic to my internal server I must have a DNS in my
FW server? or only redirect?
[FW]-eth0-> [200.179.213.245]------> Internet
|
|
|eth1 ->[192.168.1.1]
| ---------------> [Web Server ] 192.168.1.33
|----------------> [LAN Hosts] [192.168.1.2 to 192.168.1.100]
eth0-> 200.179.213.245
eth1-> 192.168.1.1
Can someone help me with this rules?
iptables -t nat -A POSTROUTING -s 192.168.1.10/24 -d any/0 -j MASQUERADE
iptables -A INPUT -p tcp -s 192.168.1.33 -d 0/0 --dport www -j ACCEPT
iptables -A OUTPUT -p tcp -s 192.168.1.33 -d 0/0 --dport www -j ACCEPT
iptables -A PREROUTING -t nat -p tcp -d 0/0 --dport www -j REDIRECT
--to-port 80
Thanks=20
