RV180 DHCP Relay

All, I'm having a hard time getting the DHCP relay function to work on one of my VLAN subnets.

I have created a new VLAN subnet and assigned the router an address of I want my DHCP range to be to 253. In the VLAN subnet configuration page I setup the router to be a DHCP relay to remote server

With this configuration I cannot get the DHCP requests to hit my DHCP server. If I take a wireshark capure I see the DHCP discover broadcasts but they never leave the subnet or get answered. Am I configuring something wrong? InterVLAN routing is enabled and I can ping the DHCP server from this VLAN. I can't seem to figure this out!

RV180 DHCP Relay

Hi Taylor, thank you for using our forum, my name is Luis I am part of the Small business Support community. You need to set your DHCP server address in Networking > LAN (Local Network) > IPv4 LAN (Local Network). Select DHCP relay and set the Server IP Address. However if you already did that, you could check the port interfaces and Vlan configuration.

If all of these are correctly I suggest you to test dropping the server firewall, if you succeed and receive the DHCP from the server, so you need to configure a rule in the firewall server for the traffic to the Router. 

I hope you find this answer useful
