So this is the current setup - essentially I would like to get my DHCP server, serving DHCP requests for two seperate subnets.
Netgear DG834G acting as a modem connected to a Sonicwall Pro 2040.
X0 - LAN - 192.168.1.0/24
X1 - WAN - <WAN-IP>
X2 - WLAN - 192.168.10.0/24
At the moment, I have a 2008R2 server with DHCP installed, with an IP address on the 192.168.1.0/24 range handling DHCP fine for this subnet.
The Sonicwall is configured correctly - anything connected to the WLAN has Full Allow to anything in the LAN, and vice versa but it will not lease an IP from my Server.
I've also added another IP address to the server, so the physical NIC now has two IP's:
192.168.10.2 with a DHCP scope configured for each.
Still no luck!
