-A INPUT -i eth1 -p tcp --destination-port 25 -j REJECT
-A INPUT -i eth1 -p tcp --destination-port 5432 -j REJECT
-A INPUT -i eth1 -p tcp --destination-port 22 -j ACCEPT
-A INPUT -i eth1 -p tcp --destination-port 80 -j ACCEPT
-A INPUT -i eth1 -p tcp --destination-port 443 -j ACCEPT
-A OUTPUT -i eth1 -p tcp --destination-port 25 -j ACCEPT

It shouldn't let to expose 25 and 5432 through the firewall.
 unblock ports 22 for ssh, 80 for http and 443 for https.
25 should be kept open for outgoing traffic only

I am getting this output:      


    * It appears that your IP address, 203.145.173.2, is listed in the Spamhaus Exploits Block List which is a list of IP addresses of hijacked PC's infected by illegal 3rd party exploits, open proxies (HTTP, socks, AnalogX, wingate, etc), worms/viruses with built-in spam engines, and other types of trojan-horse exploits.
    * Until your IP address has been removed your IP address will not be able to use this service.
    * Please please be sure to get your IP address removed from the Spamhaus Exploits Block List before using this service again.

IP Address Lookup

            74.XX.XX.71+ is not a valid IP address.



If the IP you are checking is not in our database, but you are receiving bounce messages saying it is, then it is probable the IP has been removed from our database but DNS servers around the internet have not yet updated. In this case, wait 1-2 hours and the blocking should clear by itself.

This lookup tool is for manual (non-automated) lookups only. Any perceived use of automated tools to access this system will result in firewalling or other countermeasures.

You don't need to tell it to me, you need to insert it on the spamhaus website.

If you do this way your IP will be removed from the block list and finally you will be able to use the port scanner on the first post.
