Hi
I have a gateway (CentOS) with eth0 and eth1 as
interfaces. ?eth0? is exposed to WAN and ?eth1? to
the LAN network , I want all POP3 packets coming in
through the gateway wan interface (eth0) to be
redirected to the PS1(192.168.242.129 inside the lan)
port 8110 . I had done some iptables settings as
iptables -t nat -A PREROUTING -i eth0 -p tcp --dport
pop3 -j DNAT --to 192.168.242.129:8110
iptables -A FORWARD -i eth0 -p tcp --dport 8110
-d 192.168.242.129 -j ACCEPT
In this setup POP3 packets were not redirected to
PS1 (192.168.242.129)
###
>From the gateway iptables -L gives
[root@gateway ~]# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy DROP)
target prot opt source destination
ACCEPT all -- anywhere anywhere
state RELATED,ESTABLISHED
ACCEPT all -- anywhere anywhere
LOG all -- anywhere anywhere
LOG level warning
ACCEPT tcp -- anywhere
192.168.242.129 tcp dpt:8110
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
###
Guidance requested
Thanks
Joseph John
