Re: Block port 80 allow port 110&25



Please check first

#iptables -vL -n

If there will be any rules in /etc/sysconfig/iptables the rules which
you append will be given last number.

so first check and then if you found any rules there try

iptables -I instead iptables -A

thanks for your help

Maybe use iptables ???? or google ?

iptables -A INPUT -p tcp --dport 25 -j ACCEPT
iptables -A INPUT -p tcp --dport 110 -j ACCEPT
iptables -A INPUT -p tcp --dport 80 -j REJECT --reject-with tcp-reset
iptables -A INPUT -p tcp --dport 1:1024 -j DROP
