DHCP Server

Greetings.. 


So I am using UTM 9..  I have 2 networks setup on my internal NIC.  I have untagged vlan 1 and tagged vlan 10.  VLAN 1 works fine.  VLAN 10 routes though my switch to UTM..  I can see traffic flowing though the vlan... HOWEVER when a dhcp client connects it always get an IP from vlan 1 and not the DHCP server setup to listen on vlan 10..  WHY?!?!??!

Here is a snippet of traffic on VLAN 10 when my device requests an IP.

  • Let us know if getting rid of VLAN 1 doesn't solve this problem, too.
