In fact I tried using a Windows machine as a client, where I did not see any DHCP OFFER reply from the server (no packets at all from the DHCP server if I did not overlook any, since the windows machine was just sending a lot if crap out). It looks like the remote device is not receiving the DHCP OFFER. I see a DHCP DISCOVERY packet coming in, then a DHCP OFFER is sent to the remote device and is later on acknoledged via DHCP ACK from the remote device.īut, for this special NIC (LogiLink 2-Port Gigabit LAN PCI-Express, PC0075 v.2.0 Chipset: RTL8111F see datasheet) I just see multiple DHCP DISCOVERY packets coming in which are replied with a DHCP OFFER on the DHCP server side. This works for the other NICs on the computer. Just NICs and direct connections via RJ45-cable. Note: There is no router/switch in the setup. I'm experiencing some strange behaviour with a Dual Gigabit Ethernet NIC I've setup a computer which has multiple network interfaces to connect some industrial cameras and setup a DHCP Server (isc-dhcp-server, Ubuntu 16.04) to statically assign their IPs.
