Hi everyone,

Hope you can help me with this one, im trying to setup one dhcp server to release IP in different vlan's.

I've been successfully setup my box using multiple IP's. I can ping VLAN2 clients with the IP block 192.168.10.1/24, VLAN3=192.168.20.1/24, VLAN4=192.168.30.1/24 and so on...

VLan is for that purpose only, you cannot connect to diffrent subnet. VLAN allows having several VLANs over a single switch in such a manner that all the LANs will operate in parallel and may not be even aware of each other


There are several types of VLANs and I don't know which one you got so you may or may not able to communicate.

I guess you need to setup DHCP relay; It extends the reach of the DHCP server without the need for multiple DHCP servers on each subnet by acting as the DHCP server’s helper agent in a remote subnet.

Just look at Cisco 1800 Series Integrated Services Routers (Fixed) Software Configuration Guide - Configuring a LAN with DHCP and VLANs [Cisco 1800 Series Integrated Services Routers] - Cisco Systems for more examples
