Customizing the MailCleaner firewall
Added about 5 years ago
If you change the MailCleaner server's firewall rules with iptables directly, the changes will only be temporary and will be removed on next reboot.
Here is how to add definitively some rules to the MailCleaner firewall
Log on your master node in command line
Connect to the master instance of MySQL
/usr/mailcleaner/bin/mc_mysql -m mc_config
Add the rlues via such sql statements :
This allows the IP 192.168.0.1 to connect via ssh to the server.
insert into external_access (service,port,protocol,allowed_ip) values ('SSH','22','TCP','192.168.0.1/32');
This is an equivalent to
iptables -A INPUT -s 192.168.0.1/32 -p tcp -m tcp --dport 22 -j ACCEPT
(exit from MySQL)
Restart the firewall
