Incorrect Subnet Mask from DHCP router
Posted on 2009-04-20
I have changed the layout of my network around, and am having trouble with the DHCP on my router. I have the network set up so that the servers and employee computers have static IP's in the 192.168.1.x subnet and any guests or clients that come into the office and connect to the internet are assigned IP's in the 192.168.0.x subnet. My router is currently 192.168.0.1 with a 255.255.254.0 subnet mask and all the employee computers and servers also have a 255.255.254.0 subnet so they are able to access the internet. Here is where my problem is though. On my router, i have Enabled the DHCP to hand out addresses between 192.168.0.1 and 192.168.0.100 with a 255.255.255.0 subnet. When i was testing it i kept getting an IP in the right range, but a subnet of 255.255.254.0. I have no idea why it is giving out the wrong subnet mask. I want it so that any dynamic connections to our network will be able to talk to the router, but not the servers and employee computers (hence the separate subnets). Any idea's why this might be happening?
