Network Segmentation

In this page I will try to guide you building your network segmentation, this is very useful if you have large network in one building, or you have one building that have many floor and you want to manage it.

For that case, first I will create virtual LAN (vlan) for every IP segment. In this example I use AT9816GB switch from Allied Telesys.

# create vlan=vlanx vid=x type=subnet

# add vlan=vlanx subnet=xx.xx.xx mask=xx.xx.xx

# add vlan=vlanx port=x

# add ip interface=vlanx ipaddress=xx.xx.xx.xx

After creating vlan for every IP Segment, now u can add DHCP server for that every segment so the client in every segment can automatically use IP address.

But don’t forget after all of that u must create routing for every segment in your gateway server that make the segment can communicate with the other according to your rule.
