Terraform Docker Provider: "Bind" port to specific network - docker

Question

Launching a Docker Container that supports three networks: Default Bridge(OAM), Bridge(Data In), & MacVLAN(Data Out). The problem is that the Docker Provider seems to setup all the defined ports on the Default Bridge. How do I tell Terraform to bind the defined ports to a specific Docker Network??
The .tf file snippit:
ports {
# Data-In (Bridge)
internal = 881
external = 881
}
ports {
# SSH Access on Default Bridge
internal = 22
external = 222
}
networks_advanced {
name = "bridge"
}
networks_advanced {
name = "data-in-net"
}
networks_advanced {
name = "data-out-net"
}
The Docker networks:
# docker network list
NETWORK ID NAME DRIVER SCOPE
1c2441b0b530 bridge bridge local
c68892f0c6e5 host host local
bb45d9dcbad1 none null local
a318d3bf3075 data-out-net macvlan local
af806334c7bf data-in-net bridge local
Port 222 works, port 881 does not.
IPTables from the host OS running Docker:
Chain DOCKER (2 references)
target prot opt source destination
ACCEPT tcp -- anywhere 172.17.0.2 tcp dpt:9000
ACCEPT tcp -- anywhere 172.17.0.2 tcp dpt:8000
ACCEPT tcp -- anywhere 192.168.32.2 tcp dpt:601
ACCEPT udp -- anywhere 192.168.32.2 udp dpt:syslog
ACCEPT tcp -- anywhere 172.17.0.3 tcp dpt:881
ACCEPT tcp -- anywhere 172.17.0.3 tcp dpt:https
ACCEPT tcp -- anywhere 172.17.0.3 tcp dpt:ssh
The tcp dpt:881 line needs to have a destination of 192.168.32.3. The syslog container ONLY uses the Data-In Docker Network, and thus has a correct IP address.
Any sugggestions/workarounds?? Thanks! :)
