Multiple DHCP scopes with seperate NIC's

-

hi,

are there known issues using dhcp server (windows server 2008 r2) 2 nic's serve clients different network ranges? know use ip helper on router (which remote sites), without 1 on local network. additionally, the previous (novell) dhcp server setup way.

server nic's

-nic1: 192.168.1.1/24 gateway 192.168.1.254

-nic2: 10.10.1.1/24 gateway 10.10.1.254

scopes:

- 192.168.1.10-100/24

- 192.168.2.10-100/24 (remote site using ip helper)

- 10.10.1.10-100/24

thanks help.

hi lakend,


firstly, please feel free run multihomed dhcp server. have multihomed dhcp server in lab, , works properly.


and, fyi


multihomed dhcp servers

design option 4: multihomed dhcp servers


multihomed dhcp server not allocate ip addresses

a windows server 2008-based multi-homed dhcp server not authorized in dhcp mmc snap-in though authorized dhcp server using server manager

multihomed dhcp server assigns duplicate ip addresses


however, notice have multiple default gateway configured. avoid issues, please make sure have set correct metric 2 interfaces.
