Help! Firewall

[Kleiv]

Hello! I have a server with 3 RJ45 connections.

- The first port is connected to the internet

- The second is connected to a switch

- The third is connected to a second server

I want to run a local network on the second port with normal internet access, and open access to the shared storage on my server when connected to a RJ45 port in the switch (automatic access, where you don’t need to connect to the same workgroup, if that’s possible?)

Or will it work to just have a firewall on the second server, and leaving the first at it is? Or would this cripple the other network?

On the second port I’m gone have regular internet access with shared storage and such.

is it a easier way to achieve roughly the same thing?
