Hello,
I know it’s not tech support for NAS but I have problem I think more specific to internals of docker than system it is running on (I may be wrong).
I can communicate with containers through exposed ports from outside the world and from within same docker-compose (same network). But I cannot communicate through exposed ports within different docker-comose (different switches). I tried via qnap ip adress (192.168.0.123) via container ip address (172.29.44.3) nothing works (connection freezes and timeout after few seconds). Can someone please help me. Steer me to the right direction. I have wasted whole night yesterday trying to figure it out looking at forums and I found nothing. This setup works perfectly on docker desktop (windows) - but for some reason it doesn’t work on qnap. I dont want containers to share the same network because I want to restrict communication only to exposed ports and dont want to create special network that all my dockers need to share.
I attached screen from qnap network & virtual switches. Red line don’t work - everything else (green, yellow, purple) does work.
Please help.
