I am trying to add a switch in between my modem and my firewall.  The modem is trying to give the firewall a DHCP IP address but it will not pass.  If I plug in a Fortinet switch it works.  I tried resetting the switch to factory and it didn't work.  I then tried spanning-tree portfast and it still isn't working.  Below is the config.  I was using port 45 and port 46.
