Re: ip helper for a specific address

IP HELPER forwards DHCP REQUESTS. The workstation sends DHCP request when it
HAS NO IP ADDRESS. It means that you cannot filter IP Helper requests based
on IP addresses.

If you want to have a different DHCP servers for different PCs, you may
install two or more DHCP servers (physical servers), configure certain MAC
addresses to get a specific IP addresses (static DHCP assignment), and
configure multiple "ip helper" addresses on your router. In this case your
DHCP requests will be forwarded to ALL DHCP servers, but the only DHCP
server with specific configuration (assignment) will reply to certain
requests.

Good luck,

Is there a way to specify an "ip helper" rule for a specific address
so that only UDP traffic from THAT ip address is forwarded to a
different subnet?

For example udp from 192.168.1.15 -> 192.168.2.18

I know that you can do 192.168.1/24 -> 192.168.2.18, i was just
hopping there was a way to only forward a single address.

Couldnt he use the IP helper address then just make an ACL to filter
which packets are forwarded?
