Hi, I was trying to use workbench for mysql I did the following sudo iptables -I INPUT -p tcp -m tcp --dport 3306 -j ACCEPT sudo iptables-save | sudo tee /etc/iptables/rules.v4 However, it doesn't work... it does not connect (from workbench) I also think that is not a secure connection... maybe I need to use ssl? My rules.v4 looks like this Generated by iptables-save v1.4.14 on Tue Sep 24 16:38:30 2013 *filter :INPUT ACCEPT [87:7016] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [74:6968] -A INPUT -p tcp -m tcp --dport 3306 -j ACCEPT COMMIT # Completed on Tue Sep 24 16:38:30 2013 However, I notice that 3306 is already open based on this file, before -A INPUT (in :INPUT ACCEPT) or do I have to create a VPN to have a more secure connection? I would like to be able to use mysql workbench By the way, I'm running MariaDB on Debian 7 64 bits
