I got the following log entry in my router:
forward: in:bridge1 out:bridge1, src-mac bc:5f:f4:b4:0b:5d, proto UDP, 192.168.0.163:49402->192.168.0.211:161, len 105
0.163 is computer with Epson Status Monitor installed
0.211 is the Epson printer
bridge has two interfaces (LAN and WLAN) but WLAN is not used.
Why is this connection passing through the router? Both devices are in the same subnet and directly connected to a switch in front of the router…
