But the iPXE didn't got correct gateway from it. The DHCP server is 10.210.0.11, and the client is in another VLAN which gateway is 10.211.0.1. I captured Ethernet packages by tcpdump, and also used a Windows Server 2012 for comparison. It seems ISC-DHCP-Server sent a wrong gateway. Is this a configuration issue or a bug of ISC-DHCP-Server? Here is the screen capture. The DHCP configuration I used. # DHCP Server Configuration file\n#see /usr/share/doc/dhcp*/dhcpd.conf.sample # This file was created by FOG #Definition of PXE-specific options # Code 1: Multicast IP
