Error fired by DHCPd upon adding VLAN interfaces
-
Hi,
I am on the process of configuring VLANS but everytime I successfully created 1 vlan interface, dhcp will fire up an error and everything will lose their internet connections. Below is the error encountered. Hopefully someone would like to share their ideas on how to resolve this problem. Thank you..

Multiple interfaces match the same shared network
What IP address ranges are you setting on your interfaces (external and internal)? And what DHCP parameters are you setting on each VLAN?
Another thought: Are you using a VLAN-capable switch?
-
You have to have interfaces whose IP subnets overlap. Fix that.

Thank you. I just realized the error after few seconds after clicking post button. :)
