If i'm correct, looking at the last paragraph of the log
The device with IP-address 192.168.2.150 (the source, hence "SRC=") is trying to connect to a Device with IP-Address 72.130.43.15 (the destination, hence "DST=").
The MAC-adress of the device that the traffic is destinated for is: "45:00:00:22:15:9c", (the destination MAC-adress, hence DMAC=
The MAC-adress of the device that the traffic is destined for is: "45:00:00:22:15:9c".
The MAC-address of the device that is trying to connect with the outside device is "40:00:7f:06:45:d4" (hence "SMAC=").
The Protocol that is being used to try and communicate is TCP, the source port 53531 (the port that the device that is sending the traffic with) is and the destination port is (the port that the device is sending traffic to) = port 443.
Now, i would be hesitant to allow traffic that'sbeing blocked, before being certain that it's okay e.g. non malicious.
That being said, looking at the last paragraph you would need to go to Firewall > Access Rules > ADD:
Allow https / 443 traffic (listed under "service" in the ACL menu).
Source interface would probably need to be set to "LAN"
Source IP would be set to "Range" / "192.168.2.0 - 192.168.2.255"
Destination IP would be set to: "72.130.43.15"
