Hello addendum to the queries...
I wish to connect our satellite modem/router through a file server (with 2 Nics) then connect the other NIC to our LAN.
NIC1: from router/modem to server have 192.xx.xx.xx series, DHCP enable. NIC2: from server to LAN have 200.xx.xx.xx series.
how can i bridge NIC1 and NIC2 to distribute internet access to other client computer?
In windows all you would need to do is on NIC1, go to properties > Advanced > tick the check box for 'Allow other network users to connect through this computer's internet connection' then select the interface that you want to share with from the drop down.
P.S you might get more responses if you post a seperate thread
