IP_serve1_DMZ =192.168.2.2 IP_serve2_DMZ =192.168.2.3
IP_server1_public = x.x.x.52 IP_server2_public = x.x.x.53 (x is for privacy..)
My firewall has
eth1 internet interface = x.x.x.50 eth0 dmz interface = 192.168.2.1
I need to have my server access with their pubbic IP, but I've only eth1 as inteface to internet.
I read that I can't use alias in iptables rules (like eth1:1 etc) , then what kind of rules have I to write to solve my problem?
I did this script but is it not working, what do you think is wrong in it?
#!/bin/bash
iptables -F
iptables -t nat -F
iptables -t mangle -F
# filter table everythingd is ACCEPT only to follow the easyest way#
iptables -P INPUT ACCEPT iptables -P FORWARD ACCEPT iptables -P OUTPUT ACCEPT
## make DMZ -> internet ##
iptables -t nat -A POSTROUTING -s 192.168.2.1 -o eth1 -j SNAT --to-source 82.190.228.52
## make internet -> DMZ ##
iptables -t nat -A PREROUTING -i eth1 -d x.x.x.52 -j DNAT --to-destination 192.168.2.1
Thanks
