 iPXE DHCP got wrong gateway
I installed a Ubuntu 16.04 and isc-dhcp-server 4.3.3-5ubuntu12.6.
The PXE bootrom got correct gateway, but the iPXE didn't.
Screen capture (I couldn't upload attachment for some reason...):
http://pan.baidu.com/s/1jIiFVHO
The DHCP server is 10.210.0.11, and the client is in another VLAN which gateway is 10.211.0.1.
Anything wrong?
I captured ethernet packages.
