Hi,

I'm trying to configure an IP ACL rule to allow outgoing mail on TCP port 587 for a video recorder otherwise blocked from internet, only accessible with my own PC. Video recorder being pluged to let say port 1 of my switch, local IP adress 192.168.1.xxx. The mail are send to gmail using port 587 TLS protocol

Trying to understand what is wrong with my setting, I tried to bind the ACL rule in the attached screenshot (and only this one) to the port 1 of my switch, it blocks the outgoing mail, whereas I use FFFF or 0000 as mask for TCP port 587

The 2 other IP ACL rules I'll bind to the port are working, the first one permit video recorder IP (source) to computer IP (destination), any protocol, and the last one video recorder IP (source) to all IP (destination), any protocol, deny

I intended do put the TCP ACL rule first, followed by the 2 other described, but since already just the TCP ACL rule blocks outgoing mail instead of permitting it I think there is something I don't understand

Sorry for the lack of knowledge

Thanks in advance for your help
