How to? noob alert

Question

Hello Everyone, 
 
 Please be patient on me. noob alert. 
 
 What i need. I have one router that has DHCP on to give address to my network. I want to put the UTM in a PC with 3 network interfaces. I want to put 2 different networks receiving the Internet from the router. I have to switches also. One for workstations the other one for cctv. But i want them to communicate. I can i do that? Some help please. 
 NIC 1 192.168.1.1/254 255.255.255.0 
 NIC 2 192.168.2.1/254 255.255.255.0 
 Best regards

As far as I can figure out from your question you now have: 
 
 Internet --> Router --> Internal network. 
 
 and you want to go to: 
 
 Internet --> Router --> Sophos UTM --> 2 different internal networks 
 
 That is possible with UTM without too much problems. You will need to create firewall rules to allow traffic between the 2 internal networks, since everything that you don't allow is by default not allowed on the UTM. 
 If you have more specific questions, than please ask them as specified as possible and whenever possible for each question a separate thread on the forum.

Hi, Nuno, and welcome to the UTM Community! 
 All I can add to apijnappels' response is that you should consider configuring your router so that the UTM can have a public IP on its External interface.
