We currently use a UDP Profile for DHCP and DHCP Fingerprinting.
In terms of using it for PXE boot is it just a case of adding a few more lines of text to include the PXE server?
I believe its 4011, pxe port.
see below our current udp profile
entry one {
if match all {
destination-port 67;
} then {
destination-ipaddress ;
}
}
entry two {
if match all {
destination-port 67;
} then {
destination-ipaddress ;
}
}
entry three {
if match all {
destination-port 67;
} then {
destination-ipaddress ;
}
}
entry four {
if match all {
destination-port 67;
} then {
destination-ipaddress ;
}
}
can i just add entry five and specify destination-port 4011 and dest-ip as pxe server IP?

Hi guys,
I’m curious, can someone enlighten me the reason behind this? I know that this will send all DHCP packets to the specified IP-Address… but why? Ah DHCP-Request will also find its way to the DHCP-Server without these lines. (If it’s in the same network)

Hi Ian,
You may also need tftp(udp port 69) as welll depending on the PXE server but that could be also be added as entry 6:
entry five {
if match all {
destination-port 4011;
} then {
destination-ipaddress ;
}
}
entry six {
if match all {
destination-port 69;
} then {
destination-ipaddress ;
}
}
Thanks,
Chris Thompson
