The router is running OpenBSD 7.4. Not the first time I did that, but I reset the network config of the iPhone, restarted the router and now it works :-| Pardon the noise...

Complete failures are fairly easy to troubleshoot, partial failures become more complicated.

O.K. - I tested a TCP connection via "ELX TCP Client" to different hosts and ports; if the app isn't lying, connections can be made via TCP... Since ping is working, I guess ICMP is working too; to be safe, I purchased a second AR5BXB92 for my APU to finally rule out this error. I opened a support ticket with Cupertino, since TCP seems to be clearly working, according to the mentioned app - just "regular" connections can't be openend to HTTP, IMAP et al, via TCP in different apps... They will call me at Saturday - I'll report! Debugging such a thing on a smartphone sucks :-|
