Can't tranfer data from old iPhone to new

[Imnot A Robot]

Shot in the dark here, but this happened with my iPhone a year ago, now my wife's, and I can't figure why old to new iPhone data transfers won't work on my network.

I don't see Adguard blocking anything Apple, nor the firewall except for the occasional WAN incoming. Everything else on my network works fine.

Anybody care to take a stab in the dark as to why this Apple function won't work on my network?

Thanks

Assuming both phones are in the same subnet, any network traffic between them might not even go through OPNsense (e.g. if they connect to the same wireless access point). And if both phones are not on the same subnet, then they probably won't see each other.
