Dhcpd tftpserver option install#
After the switch has completed the DHCP transaction on the Primary VLAN, the two options will cause the switch to download the. Here are a few screen shots which demonstrate some of these additional option choices: After a vanilla install of DHCP role, open the DHCP console: After right-clicking on Server Options: After selecting Configure Options: As an example, from this list I want to select a DNS server, so I choose option 6 and enter 4.2.2. DHCP Options 66/67 allows an option to include an IP address of a TFTP Server (Option 66) and the name of a configuration file (Option 67) in a DHCP ACK packet.
Dhcpd tftpserver option update#
I also tried to add a DNAT rule as suggested here. Enabling configuration file update using Option 66. For more information about various DHCP options, read this topic.

(No syntax error, nothing wrong with escape characters as mentioned here: ) DHCP option 150 supports a list of TFTP servers (Multiple Server IPs) DHCP option 66 only supports the IP address or the hostname of a single TFTP server. DHCP options are tagged data items that provide information to a DHCP client. Now when setting up a DHCP in the server VLAN and adding these options to that DHCP and setting the client to PXE boot from the server VLAN DHCP everything works fine and the client receives a boot image and starts to PXE boot. So somehow the client is trying to TFTPboot from the DHCP/Sophos although the option TFTPServer has been set. Now when I PXE boot a client in the Client VLAN it receives a DHCP IP address and that's it - nothing more. Please refer to RFC2132/RFC5859 for more.

In short: When WDS and Client are on different subnets there's no communication. I have a problem with my WDS/DHCP configuration.
