Hello Everyone. We are going to be connecting our Stores to our Main Head Office Via Fiber. We want to separate our Internal Lan from the store computers. So we have decided to separate them by networks [ip addressing] because of security. Head Office I have 3 Servers in my LAN. And 4 Networks in Total inside of out Head Office. 10.10.10.1 - Pixel Replication Server 192.168.1.1 - Web Based Server [Delivery Server] 192.168.100.1 - File Server Including Internet Users. 192.168.0.1-254 [ Lan ]. The store computers that need to access specific servers, are only on that network. For example. Store 1, Computer 1 Needs to Replicate [he will have an ip of 10.10.10.105] Store 1, Computer 2 [The Delivery Pc]. he will have an ip of 192.168.1.105 Store 1, Computer 3 Will access the File Server by having an ip of 192.168.100.105. Now the Risk involved with this is we have no Real Security, For Example. A Malicious user can easily change his ip address to 192.168.0.105 For Example and Get on our Head Office Internal Network. Which We don't Want. So i would like to Setup, Install And Configure a FreeBSD Based Firewall, that will have 4 Network Cards, and will be placed between Our Head Office Switch, and out Fibre Switch [Wan]. But AFAIK, By Placing all these network cards in the Same Machine, FreeBSD Will Bridge All Those Networks. How Can i keep the networks Separate, and Secure the Servers by Firewalling by ip addressing? I would appreciate Advice / Suggestions / Anything That will give me a better clue on how to secure my network.
