FG as DHCP server for few VLANs connected with trunk

Hi ALL,

 

I have a trunk connection from a Dell switch to FG physical ports - with 3 sub-interface VLANs, each VLAN will getting IPs from FG's DHCP server. Currently, I can see that the client can get an IP Address from FG (as seen in DHCP Monitor & also found in Device Inventory), however, the client always looping that to show "Obtaining IP address..."

 

Anyone has idea about this scenario? The FG is running v5.6.0 latest version and the trunk mode on dell switch is configured.

 

Many thanks!!

One month later: did you nail this? What was the issue? 

If not we can tshoot further down or look for a 5.6.x bug

Hello,

 

I am also having erratic behavior from DHCP server in FG60E with 5.6.3 with multiple VLANs in a trunk.

 

I manage more than 20 FG60E, the differences being that it has multiple DHCP servers with dozens of devices, while the others FG60E just have one DHCP server with a few devices.
