Remotely Accessing Containers

General
1

Hi,
I’ve pretty much scraped the bottom of the internet and I don’t understand how I cannot find a solution to this problem of remotely accessing my containers.

My Asustor as5304t sits on a static ip address in another room on 192.168.1.148, my main machine that I used to configure everything sits on a static ip address of 192.168.1.100, whenever I try to connect to ‘any’ container by means of a web browser in this instance we’ll use ‘Portainer-CE’ as an example on 192.168.1.148:19900 I encounter ‘ERR_CONNECTION_TIMED_OUT’, if I access the the Asustor AS5304T from the lounge directly thought the TV however everything works out fine because it’s ‘localhost’, but accessing from any other device is blocked.

— Assuming that Portainer-CE is communicating through the bridge connection, the IP address of 172.17.x.x is wrong in fact the entire address is wrong, do I need to change this to be on the proper network address 192.168.1.x or am I missing something?

A bridged network in docker is like a private network. Publishing ports is like forwarding ports in a nat router (very similar in behavior but not identical). Thus said, the bridge network’s ip range looks fine to me.

Though did you publish a port? And use the NAS’ses ip or host name and the host side of your published port mapping to access the container?

I’m not a networking guru, but does a ping work? :blush:
