Hi all.
I have set up a DHCP server with multiple subnet configurations (let's say subnet A and B). Within that I have declared pools and static hosts addresses.
Now, if I have set up a static host entry (with fixed-address) in Subnet B for a specific machine and try to connect to Subnet A with that NIC (where it should obtain an address from the range), this does not work unless I add a static host entry for that machine to the Subnet A declaration, too. I even have to assign a fixed-address, there.
I just want the NIC to clain it's address from the range on Subnet A and to assign a fixed address on Subnet B.
You can assign multiple host blocks for the same NIC, using a fixed-address directive in one but not in other. dhcpd will try for the best match. If the request arrives from subnet-B, and the fixed address is on that net, then that's the block that gets used. Otherwise, the less specific block will be used. E.g.,
host myhost { hardware ethernet 11:22:33:44:55:66; fixed-address myhost.mydom.com; } host myhost-roam { hardware ethernet 11:22:33:44:55:66; }
