I found something very strange on my RT-AC66R. Packets sourced from wireless clients get source NAT-ed to the LAN IP address of the router for some reason. Nothing that indicates this behaviour in the iptables -nvL -t nat output. To illustrate this:
Client A (wifi) IP: 192.168.33.100 sends a packet to Client B (ethernet LAN port) IP: 192.168.33.101. I'm sniffing on Client B and instead of seeing 192.168.33.100 as Source IP I'm seeing 192.168.33.1 as Source IP (which is the router's LAN IP). Any idea what causes this behaviour? Is it the default one or I might have caused by some configuration change? It's breaking a whole bunch of applications.
Firmware version is: 374.40
