i want to redesign my network for security reasons. the company has some static IPs. we have 1web server,2 application server (AS). the AS is used by the staff to do their everyday tasks. we also have branch offices around the country and these branch users connect remotely via RDP to the AS and do their work. these servers are directly connect to the a D-Link switch on which the ISP internet is connected.then we have another D-Link switch which again the servers are connected to. I mean these servers have two NICs,one of these NIC is WAN and another as LAN. the LAN is for the local users and the WAN for the remote users.
Now I want to put a UTM between the ISP internet and the local network. the UTM i have selected is Zentyal(EBox). i have setup a machine for Zentyal. now my question is how do i forward 3 static ips to the respective servers i.e. 2 AS and 1 WS.
the Port Forwarding of Zentyal has these parameters.
my setup is like this eth0 is WAN and eth1 is LAN. Now....when i go to Firewall--> Port Forwarding
please help me to config a new forwarding
Interface: what do i need to select
Original destination: what do i select
Original destination port: I will select Single port: 3389 (correct??)
Protocol: TCP (correct??)
Source:what do i select
Destination IP: ??
