DHCP Server - Multiple routed VLANs
I have a scenario where I need to use pfsense to provide DHCP leases to a remote routed VLAN, in the same fashion as using Windows DHCP server etc and IP helpers.
A basic view of my topology is as follows:
Remote Office Cisco Switch –--- GRE TUNNEL OVER WAN ----- Local Office Cisco Switch -------- pfSense
Now pfSense happily provides DHCP leases all day long to the local office, but given the remote office's VLAN is routed I obviously can't trunk it to the pfSense machine. I've set an ip helper on the remote office to relay requests to the pfsense server however I can't seem to figure out how to get the GUI to allow me to define the remote subnet as a DHCP scope.
Any ideas or this this beyond the realms of the GUI?
I believe ISC-DHCP-Server is limited to a single subnet per interface.
