I can't help you with your specific problem, but one thing is that you
need to do, is to enable the machine to forward ip packets from one
interface to another.  Create something like
a /etc/sysctl.d/99-sysctl.conf and add this:

# Enable packet forwarding
net.ipv4.ip_forward = 1
net.ipv6.conf.all.forwarding = 1

If you run a firewall like iptables you'll also have to enable packet
forwarding between the interfaces in the firewall.
