Xe300, filtering outbound traffic by IP or port?

I’m a new user here, i got an xe300 to test and am wondering what the best method would to block all outbound traffic except for certain IP and ports? Is this possible?
For example, can i block outbound traffic on port 110 to not allow pop3 unsecure email access?


You can try to configure it in LuCI’s firewall by modifying the zones and adding rules.

Thanks. I must be missing something in the firewall page, i hadn’t noticed a zone config. I’ll check it out and get back with you if i need more.

And i found it. I didn’t realize what the advanced config page was until this morning.
