The above mentioned link claims "that most dnsmasq is not able to boot most UEFI devices as it uses DHCP option 43 which they don’t like ..." For that reason I'vd tried a configuration with isc-dhcp-server instead. Again, I'm able to connect to several clients but - unfortuantely, I'm not able to connect to the UEFI-client. It seems that the problem is related to some tftp-communication problem ... (compare https://ask.wireshark.org/questions/22519/tftp-transfer-option-negotiation-failed-error-8-packet-trace). ... but I could not find a solution (link) for this problem. If someone has been able to connect to an UEFI client, please let me know. ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
