    Hey there,

    I am having difficulty with access rules and feel that I'm missing something small here.

    I run a server behind my RV082 with the ip address That server runs MySQL on the standard port 3306.

    My question is: Since its a security risk to have the port open to EVERYONE on the internet, how do I make it accessible to only certain IP addresses?

    I have setup an access rule under the firewall section:

    Allow / MySQL (TCP3306) / Source: WAN / Source IP: my ip / destination: / Time Always

    But it doesnt seem to do the trick...? :(

    I tried the Linksys online chat and was really surprised by their lack of knowledge.

    Could you not use a VPN tunnel for those external users who need access?

    Make sure that you have port 3306 forwarded to the MySQL computer LAN IP address. Go into setup and find the forwarding screen and check that TCP port (3306) is pointing to the correct LAN IP address (

    Note: By default, this creates a hidden access rule that allows all port 3306 traffic to pass through the firewall to So, you will need to have two access rules to do what you want:

    Priority #1, Allow, port 3306, WANx, yourIP,, always
    Priority #2, Deny, port 3306, WANx, Any, Any, always

    The priority order matters.

    Thanks. The priority was the key i was missing.

    Out of interest.... does anyone know how hard it was to get an answer to this seemingly simple question? I talked to linksys time after time and they *did not* understand how to help me even once. I was blown away!
