I want to implement a security scheme in a new network configuration. There are two buildings for the client:
Office Building 1 (OB1) with address 10.0.0.0 / 255.255.255.0, Gateway 10.0.0.1 ( Router1 Zyxel ). In OB1, is installed also the domain controller ( 10.0.0.250 ) where the users of OB1 have already joined to.
Office Building 2 (OB2) with address 10.0.1.0 / 255.255.255.0, Gateway 10.0.1.167 ( Installed as Internal Address (lan) of a Firewall ) Firewall wan1 device has address 192.168.5.199 and uses 192.168.5.2 as Router2 (Zyxel) address.
Router1 provides internet access for users of OB1 and Router2 provides internet access for users of OB2. In OB2 Firewall has configured for protection and web filtering for 10.0.1.0 network. Both buildings are connected through VPN implemented between Router1 and Router2.
I would like to know:
- how to setup firewall protection of OB1 ( network 10.0.0.0 ) using Firewall Device in OB2 ( perhaps with some network re-configuration )
- how to setup users in OB2 ( network 10.0.1.0 ) to join the domain implemented in Domain Controller which is part of network 10.0.0.0 in OB1
