Hello everyone,
I'm currently experiencing an issue when uploading photos from my iPhone (iOS 26.1 - App - PhotoSync) to an SMB share. The iPhone is located in the Home VLAN, while OMV (OpenMediaVault) with the SMB share is located in the Server VLAN.
There is an any-any rule in place for the iPhone between the VLANs. The connection to the share can be established without any problems, but the file transfer stops after a few images. There is no recognizable pattern: sometimes it happens after the second image, sometimes after the 25th. I have repeatedly tested with the same set of images, and the error occurs every time.
Hardware/Setup:
I'm using a Dell Wyse 5070 Extended with a dual-NIC network card (Fujitsu Ethernet Controller 2x1GB DualLan-Card S26361-D3035-A100). OPNsense is up to date and installed directly on the thin client. Intrusion Detection is not enabled. I have Zenarmor installed, but even if I disable it, the same issue occurs.
Previously, I ran Proxmox on the device with a virtualized Sophos XG Home and this setup did not have the issue.
Question:
How can I further narrow down the root cause? Unfortunately, I can't really identify anything helpful in the firewall logs.
