Usernet Portmap Noicc

Container on a user-defined network with inter-container communication disabled, with a published port

Equivalent to:

docker network create \
  -o com.docker.network.bridge.name=bridge1 \
  -o com.docker.network.bridge.enable_icc=false \
  --subnet 192.0.2.0/24 --gateway 192.0.2.1 bridge1
docker run --network bridge1 -p 8080:80 --name c1 busybox

Most rules are the same as the network with icc enabled:

{{index . "Ruleset4"}}

But ...

The filter-forward-in chain drops (instead of accepting) packets originating from the same network:

{{index . "chain filter-forward-in__bridge1"}}
