Hi, I have used a firewall m/c with the 2 interfaces, 1 Static Public IP (eth0) & Internal ip (192.168.0.1, eth1) & route the packets to mail server with internal ip 192.168.0.254 for mail receiving with the following rule. $IPT -A PREROUTING -t nat -p tcp -i eth1 --dport 25 -j DNAT --to 192.168.0.254:25 No problems in receiving mails. Problem faced by me is the IP Address of the originating mail is changed to 192.168.0.1 after the PREROUTING, due to which the SPAM filter is not happening & am receiving around 1000 Junk mails. Looking for a solution of just moving the packets with original IP to my mail server. Thanks for the help in advance.
