DHCP Server - Multiple routed VLANs



  • Hi All,

    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.
