Hello David,

the server has to be configured with static routes to used the correct NIC to go to internet.

A route print can tell how the server is going to use its NICs.

Devices with private ip addresses as per RFC1918 needs to be handled by NAT = Network Address Translation to be able to access internet.

For example this PC has an ip address 10.x.y.z but when connecting to www.cisco.com it is translated to a public ip address so that packets can be routed in both directions

see

Hope to help

Giuseppe
