Iptables -A FORWARD -s 172.17.0.0/16 -d 169.254.169.254 -j DROPДЄlso, using owner is probably not a good idea either way, because processes inside docker containers can change their uid's via eg setuid binaries (like sudo), if there are any in the image. Something similar to this should work: # single container You can either hardcode the container's IP addresses, or put containers you want filtered in a special network, and match the whole range.

In pfSense, create a static DHCP lease for the MAC and IP configuration.

#Hardcode docker ip address how to

Forwarded packets do not have any socket associated with them. The question: How to pass all ' - ' (Avahi) mapping to Docker container, so I wont need to hardcode all '', so Docker Container network dns would get hosts avahi mapping, without needs of reconfiguration Docker-compose each time when I plug-in/out new RPi. Install the correct version for your unRAID version then for each Docker you want to assign an IP, enable advanced mode, change network to 'none' and add the code below to the 'extra parameters' box specifying a unique IP/gateway and a unique valid fake MAC address.

This match is only valid in the OUTPUT and POSTROUTING chains. The issue is that -m owner doesn't work in FORWARD. Therefore, the solution is putting your rule in the FORWARD chain instead.

They go through the iptables FORWARD chain in the host's network namespace.

The host network namespace consults the routing table and decides they need to go out of e.g.

They arrive to the host's network namespace from the veth interface.They get routed out of the veth interface.They go through the iptables OUTPUT chain in the container's network namespace iptables.Packets are generated by processes in the Docker container's network namespace.The key is that 'local process' means 'a process in this network namespace', not 'a process in this machine'. OUTPUT matches packets coming from local processes.FORWARD matches packets coming in one network interface and going out another one (being routed through).INPUT matches packets going to local processes.Every network namespace has its own routing table and iptables rules, and behaves exactly as if it was a separate physical machine.

FORWARD does.Д®very Docker container runs in its own network namespace. Your issue is that OUTPUT doesn't catch packets coming out of containers.
