Docker network

hello everyone, I would like to learn how to properly install docker containers on openwrt.
I have a box with only one ethernet port, on which openwrt starts from usb.
docker is already installed, the box has two network interfaces
docker (docker0) and lan (br-lan), at boot br-lan has static ip 192.168.1.1, but my home network is 192.168.178.0 so i changed address to 192.168.178.100, i installed heimdall to try docker, the container starts with ip 172.17.0.2 but I can't view its web page, it is not reachable even from openwrt
some help configuring networks and firewalls would be appreciated
