ip-helper with two subnets

We have a 4908 where we have two subnets on the first physical port, and, and the IP-helper points to the DHCP-server. If a computer on this first port broadcasts for an IP it will get one in the span, but how could we configure it if we want that some computers should have ip-addresses in the and the some in the The relay agent always forwads it as a broadcast.

Re: ip-helper with two subnets

Are you using a secondary address seeing that you have 2 subnets on one port . If so it is always going to use the primary address as the broadcast and there is really no way around this

that I know of short of putting the subnets on different ports . I don't believe dhcp will work on a secondary address.
