DHCP Server on pfSense for L3 Switch doing InterVLAN Routing
-
Hi,
This may have been asked and answered elsewhere. If so, my apologies and could you post a link. Thanks in advance.Basically in my homelab network design/plan I have a pfSense setup with a Layer 3 switch.
After a bit of reading, I decided to use the Layer 3 switch to do the InterVLAN routing for a performance increase.
My question is, can pfSense be a DHCP Server for 4/5 VLANs from the L3 switch, while only having a single LAN NIC to the switch?pfSense has an IP of 192.168.10.1
L3 switch is 192.168.10.2
VLAN20 Network Address 192.168.20.0
VLAN30 Network Address 192.168.30.0
And so on etc...I hope this makes sense.
Thanks in advance

You'd have to set up a DHCP relay on the switch. The DHCP solicit packets are broadcasts and not passed by routers.

So pfSense can have DHCP Scopes even though it doesn't have a physical interface with that range?

If the routing is done elsewhere, you need a relay agent. If the routing is done with pfSense, then it can directly access the networks and provide DHCP directly.
