Dear John, >> Subnet A (192.168.2.x) <-> DHCP Server with 2 NICs <-> Subnet B (10.1.0.0) >> >> Clients on Subnet A should get a static IP from the host declaration. >> Clients on Subnet B should obtain dynamic IP addresses from a range. >> The two subnets are not physically connected but a CLIENT should be >> able to connect to Subnet A or to Subnet B as well. > This is what is confusing. If there *NOT* Physically Connected you will > never CONNECT to them. In this setup Subnet A is a private network and Subnet B is a network for public Wifi access. If one got a notebook and his/her mac-address is listed in Subnet A declaration he/she should be able to obtain an IP. In some situations this machine may just want to access to public wifi so he/she should also be able to connect to Subnet B as well. ATM, the client will only get an IP address if there is a static host declaration for it in both networks. Otherwise it would just be able to connect to Subnet A and will never receive an IP from the dynamic range of Subnet B. In the near future Subnet A will be migrated to a Class A network, so 'subnetting' may be possible, but I don't think that this will change the situation. I also wonder if it's really necessary to run two instances of DHCP with separate config files as dhcpd3 is able to detect the Subnets on which it may deploy leases, depending on the NIC configuration.
