I have an app on my iphone that access a hardware device on my LAN. Until recently, it was working without a hitch. I have a simple port forward rule from a fixed WAN port to a fixed LAN port. The app has input for both LAN and WAN addresses so that it can connect faster while you're on the home wifi. The issue is that it looks like the data is hitting the router (seen in packet capture AND on the port forwarding "rulesShow rules stats" setting. However, it looks like they aren't getting to where they should be going.
I can't decipher much of the packet capture screen. Is there another way to continue tracking the packets to understand where they end up and why?
