Re: [Devil-Linux-discuss] DHCP Server and VLANs

[Fred F. <ffr...@lo...>]

Don't you have three different IP's for each VLAN? I think the problem is the way the client's broadcast and the DHCP server cannot tell from which network the request is coming from. You may be able to do some trickery with iptables if you can filter by vlan there. Is the Linux box routing between vlans too? There is a way to get DHCP requests routed through a router so that they are forwarded to a DHCP server wich then knows the source and can server the correct IP.

Sorry I cannot be more helpful.

Subject: [Devil-Linux-discuss] DHCP Server and VLANs

Hi all,

I am sure this is not the best place to ask this, but I am also sure there are a lot of competent people here:

I need to run a DHCP server on a DL box that serves different pools on different VLANs that are trunked on the same interface. I see that the DHCP server serves the same pool to all VLANs, and the other pool is never used. 

Is this impossible to do? 

Thanks for any hints....

Frank
