I'm having a problem with a DHCP issue. I don't know DHCP very well yet, but am trying to learn. I have a DHCP server that has scopes in both a 255.255.255.192 Subnet and in a 255.255.255.224 Subnet. I have the last subnet in the 224 space open (x.x.x.224-x.x.x.255). I have an address assigned to my DHCP server of x.x.x.226, and have assigned my HP router the address of x.x.x.225. Problem is, I'm having problems communicating with these. Nothing will ping my router, and only the DHCP server will ping itself. Is there a connector somewhere that I'm missing? There are other nets set up in the .224 space on this server, but I didn't set them up. Could really use some help here!

Thanks!

When you set up each individual subnet you need to keep in mind that you are not able to use the first IP or the last IP of each subnet. The first IP is the subnet Network ID and the last IP is the broadcast address for that subnet. Please contact me by e-mail so I can further assist you because this can get a little involved depending on your network set up

To add a little more Answer1, also make sure that in your DHCP scopes (ranges) you exclude the IP's of your main servers/routers. So in your DHCP scope of x.x.x.224-x.x.x.255 exclude IP's of your DHCP server itself and the HP router. By doing so, you will make sure that no other network devices will take the same IP as your router. Hope this helps you out.

Had already defined the exclusion range.

What it looks like right now, after looking at the statistics on the router, is the router doesn't recognize that I added an address to it. I will be troubleshooting from there I think. Thanks!
