Docker macvlan can only ping gateway, cannot be pinged by other devices

Question

What I'm trying to achieve

I need my container to be able to ping other devices in the network. Specifically, my nginx container that now has a static IP address through macvlan.

Setup

Server (NAS):           192.168.1.1
     other container  : 192.168.1.1:32811
     nginx (container): 192.168.1.192 (macvlan bridge_lan)

Gateway:                192.168.1.254

What I've done

To setup my network I ran:

docker network create -d macvlan --subnet=192.168.1.0/24 --gateway=192.168.1.254 --ip-range=192.168.1.200/27 -o parent=eth0 bridged_lan

I then create a docker container and assigned it to the bridge_lan network. If I navigate to 192.168.1.192 I get greeted with my nginx container. A few tests shows it's almost correctly setup, where:

Network -> nginx container // every device can ping this container on network
nginx container -> network // container cannot ping any device, except for case below
nginx container -> gateway // the only device it can ping, the gateway

I'm clearly missing something here. It might be my lack of understanding but why and how do I resolve this issue? I just need my container to have its own static IP address and make it reachable on my LAN and vice versa.
