using pfSense DHCP to service other subnets via relay

[coreybrett]

I currently have a Windows DHCP server that handles all of our company's subnets via relays. How would I configure pfS to replace this old server?

pfSense can't act as a server for multiple subnets unless it has a direct L2 connection to each subnet (no relays).

Is this a pfS limit, or the underlying dhcpd?

A limitation of pfSense

Ok, thanks. I guess I'll just P2V the old server.

It's because DHCP initially uses broadcasts, which are not passed through routers. You have to set up a relay agent to get around that. PfSense can be configured as a relay, but I haven't tried that.
