We are trying to setup a new guest network at a remote site and would like to use a DHCP server at our central site.
Here is the IP setup:
IP Range 10.15.0.0/16
Default Gateway: 10.15.0.1/16
Windows 2008r2 DHCP Server: 10.41.1.2/24
Default Gateway: 10.41.1.240
There has been a DHCP Relay configured on the router at the remote site and firewall rules to match.
We can see the "DHCP Discover" when using WireShark on the DHCP server, but the server does not send any response.
The scope has been configured correctly (triple checked) and the Wireshark capture seems to look like there is at least partial connectivity.
Is there something I am missing here, such as a DHCP relay configuration at the central site in order to send the traffic back?
Or have a missed something special on the DHCP server?
This particular DHCP server handles around 10 scopes, but all for the same site, with the DHCP Relay handled by the Layer 3 switches.
Your help would be greatly appreciated!
