    Firewall allows everything by default?

    Model :

    Hardware Version : Not Clear

    Firmware Version :

    ISP : [/COLOR]

    I have a TL-ER6120 v1.0.

    I have allow rules in the firewall section, and specifically SMTP allow rules that allow incoming SMTP from certain IP's (to accommodate our email filtering service).
    I noticed this morning an email that looked suspicious and looked at the headers and saw it did not go through our email filtering service, but came direct to our IP.

    I checked my rules and only had the allow for SMTP from the specified IP's. I tested port 25 from a remote PC and sure enough, I could connect to port 25 from the outside.

    There isn't, specifically, a DENY ALL rule at a lower priority. Do I need one or should the firewall in this device be blocking everything that isn't allowed? When I tried entering one that blocked ANY IP, ANY service on WAN1, and put it at the lowest priority, it basically stopped the internet from working.

    The system is a white list as default, so if you want to allow a IP only, you should set a block all rule and give it a lower priority.
