You can use ipf or ipfw as firewall to create a set of rules, allowind and
denying access to different resources from/to different network. Also you
can use ipnat to make NAT translation if needed.
Personally I'd advice you to use ipf as packet filter, ipfw as traffic
shaper and ipnat for NAT.
Hope this will help you, there are tons of topics and howto's about using
ipf, ipfw and ipnat :)

Networking with FreeBSD
We are going to be connecting our Stores to our Main Head Office Via
We want to separate our Internal Lan from the store computers.
So we have decided to separate them by networks [ip addressing] because of
I have 3 Servers in my LAN. And 4 Networks in Total inside of out Head
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
Store 1, Computer 1 Needs to Replicate [he will have an ip of
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
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
by ip addressing?
I would appreciate Advice / Suggestions / Anything That will give me a
better clue on how to secure my network.
