How to reopen a blocked port
Ok guys,today I've blocked a bunch of ports on our servers with the command
iptables -A INPUT -p tcp --dport 23:24 -j DROP
iptables -A INPUT -p tcp --dport 26:36 -j DROP
etc...
Too bad I've blocked port 26 (exim) and the port of spamd too.

Any idea how to reopen them?
Thanks in advance
