Xe300, filtering outbound traffic by IP or port?

Hello.
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?

Thanks.

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.
