All:
I've noticed recently that my Apple iOS products no longer sync Contacts--that is, if I create a contact on my iPhone, that contact is never recognized on my iPad--until I use those products on networks other than one running through my Sophos UTM. I pulled up an WebAdmin Live Log Firewall window to see if something was being blocked. Sure enough, while using my iPad (or iPhone) I'm seeing HTTPS (443) traffic being dropped that's sourcing from Apple subnets 17.253.x.x and 17.248.x.x with the destination address being the static address assigned by my Internet Provider.
For example, if x.x.x.x is the static IP address assigned to me (which I have entered under Management-->System Settings-->Hostname), I'm seeing:
Default DROP TCP 17.253.29.204:443 --> x.x.x.x: (Some high port number like 54977) [RST] len=40 ttl=56 tos=0x00 srcmac=whatever dstmac=whatever
What's going on here and how do I remedy it? I already have firewall rules in place to allow traffic to/from Apple Networks (17.0.0.0/8) to my iPad and iPhone in place.
Any suggestions or thoughts would be appreciated.
Regards,
Robert
