I tried to configure a similar system on a VPS with red+green interface,
- host IP
- configured Active Directory DC IP
- configured IPsec tunnels
I can ping the host
<green>.2 from the remote network. However the DC IP does not respond.
To fix this situation I did the following:
yum --installroot=/var/lib/machines/nsdc install iproute iputils bind-utils
systemd-run -M nsdc -t /bin/bash
From nsdc shell:
ip ro add default via <green>.2
<green>.1 aliases: smbd seems to bind on the first IP,
Applied the proposed workaround above: I can connect from smbclient on the remote network.
@sharpec, please see if defining a default route in your nsdc container fixes your connection problems with DC (and file server).
