Apple iPhone/iCloud Backups

[newUser2pfSense]

Each time my iPhone attempts to backup to iCloud, pfSense is doing something that I'm not clear on. When I look at my dashboard at the Gateways, the Gateway goes offline and all internet connectivity ceases. A search for the ports that Apple uses for iCloud backups yielded the following ports: 25, 80, 443, 587, 993 and 5223. I created a port alias and added it to my WLAN and set it up as follows:

Action: Pass
Interface: WLAN
Address Family: IPv4
Protocol: TCP
Source: WLAN net
Destination: any
Destination Port Range: the port alias i created

The Gateway still goes offline.

A tried another backup and did a packet capture at the same time on my iPhone's IP address and found a lot of attempts at the following:
<iPhone IP>.54860 > 17.248.134.146.443: tcp 1062
<iPhone IP>.54863 > 17.132.4.200.443: tcp 1448

1448 showed up quite a bit more than 1062.

I do have Suricata running but I don't believe I've blocked anything that could be cuasing this issue. Any ideas what may be occurring? Do I need to add 1062 and 1448 to the port alias? Any suggestions would be helpful. Thank you.

Hi @newUser2pfSense - How fast is your internet connection? Is the iPhone maxing out the upload while backing up to iCloud?

I've got 50/50 mbps for my internet connection. I'm not sure if the iPhone is maxing out the upload while backing up or not. Incidentally, I added as a port 1062 and 1448 to the port alias and low and behold the Gateway stays online and everything seems to be fine.
