Question

Network administration

There is a server on the network. It is necessary that he has one white ip assigned on one network card, and 9 gray IPs in internal subnets. (There will be 9 internal subnets) The problem is how to route it all? How to bring the server to the Internet and at the same time so that you can connect to it from local subnets? And subnets of users how then to display in the Internet?

Answer 1

There may well be several addresses on one interface. This is routed in the same way as always - by adding routes to all the necessary networks. What is the difficulty, exactly? If you need to forward traffic from local networks to the Internet through this server, configure NAT.

Answer 2

And what can't you do? Registered a pack of addresses. Registered correctly routing - default through the correct gateway, other routes as needed.
