Block smtp traffic

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi list, this is my first post.

I had a internet gateway that I want to block all traffic send to smtp
ports ( 25 tcp ). I had done this:
iptables -A FORWARD -i eth1 -p tcp --dport 25 -j DROP

and I cannot make this rule work, my user still can connect to port
25.... I try to change from drop to reject and still the same problem,
where can I look for to make this work ?

thanks, Allan
