first question, are both of these containers running on the same host?, and is the host running unraid (just double checking here). If both containers ARE running on the same host then they should be able to communicate, as i have put in an iptables entry to allow docker to docker communication. If they are running on different hosts then you will need to define the new LAN_RANGE environment variable i recently fixed up to allow communication across your LAN.
yes, both on same host. I've also put 192.168.0.1-192.168.0.255 as the LAN_RANGE variable but it doesn't appear in the routing table. Other containers can contact sabnzbdvpn on its public host port, it's just that sabnzbd cannot connect outbound to a host port (to connect to nzbmegasearch). does LAN_RANGE work in sab, i thought it was just deluge per the notes?
