M7 Pro (MR7400)... Bridge Mode/IP-Passthrough Only Works After Reboot?
As the topic says... If I reboot the router to which the M7 is attached via eth, then I have to reboot the M7 as well before bridge mode works. Has anyone else experienced this, or the contrary;...

you should be able to reboot your router downstream from the M7 and it will pickup an IP after reboot. i have an M6 Pro and this is how it behaves. I imagine it's not going to be that different in the M7

Just re-read your post also and realized you were talking about rebooting my own router... My router does make the DHCP request upon reboot or when force it to DHCP release and request this has no impact on the M7.
I grabbed some packet captures on the eth interface between my router and the M7 and even though the M7 is sending out ARP requests for who has <my router's IP passthrough DHCP assigned address from the M7> from the 192.168.1.1 address it has, the M7 is simply not responding to my router's ARP requests for who has <M7 gateway IPv4 address>.
I've double checked my own firewall and given that I can't configure my router for layer 2 filtering I can't have a rule that is blocking the ARP requests, so it has to be something with the M7.
