You may need to turn on IPv4 forwarding so that your server can act as
a router and route between the two networks. You can test this theory
using this command:

   sysctl net/ipv4/ip_forward

If it says the current value is 1, then my theory is poo-poo and you should stop reading this email.

Otherwise, set it to one:

   sudo sysctl -w net/ipv4/ip_forward=1

If it doesn't work it will do no harm, but best to switch it back off:

   sudo sysctl -w net/ipv4/ip_forward=0

If it does work, make the change permanent by editing /etc/sysctl.conf
