Hello,
My Network configuration is that:
ISP

|
| *eth0 200.9.190.20* *eth0:1* 200.9.190.21 *eth0:2* 200.9.190.23
*eth0:3* 200.9.190.24 *eth0:4* 200.9.190.25
LINUX BOX
| *eth1 10.24.54.1/32*
|
|
LAN 10.24.54.0/24 gw 10.24.54.1
|
|
MAIL SERVER 10.54.24.96/32 gw 10.24.54.1
All machines to get out to INTERNET through my LINUX BOX included my
MAIL SERVER but i want that MAIL SERVER to get out to INTERNET with IP
Public Address different like 200.9.190.25 and my all rest network get
out through 200.9.190.20
The rules i have applied like this but i don't know how to do that:
/sbin/iptables -t nat -A PREROUTING -i eth1 -s 10.24.54.0/255.255.255.0
-d 0/0 -p tcp --dport 80 -j REDIRECT --to-port 8080
/sbin/iptables -t nat -A PREROUTING -i eth1 -s 10.24.54.0/255.255.255.0
-d 0/0 -p tcp --dport 8080 -j REDIRECT --to-port 8080
/sbin/iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
/sbin/iptables -t nat -A PREROUTING -p tcp -i eth0 -d 200.9.190.20
--dport 25 -j DNAT --to-destination 10.24.54.96:25
/sbin/iptables -t nat -A PREROUTING -p tcp -i eth0 -d 200.9.190.20
--dport 110 -j DNAT --to-destination 10.24.54.96:110
/sbin/iptables -t nat -A PREROUTING -p tcp -i eth0 -d 200.9.190.20
--dport 143 -j DNAT --to-destination 10.24.54.96:143
Any help or suggestions ??
