Hello,
We are using RL-RTX and RL-TCPnet and having a difficult time on some of our units getting assigned addresses from the DHCP Server. Ideally the DHCP Server would test the address before offering it but there is no requirement to do so and evidently ours has that feature disabled. The other side of the ideal situation is for the client to test the address with an ARP and if a response is received send back a decline message to tell the DHCP Server to allocate a different IP address. Unless I am missing something, there is no mechanism within RL-TCPnet to implement testing an offered address prior to sending the Request message. I also see no way to initiate sending a DHCP Release message to release an IP address. Is this functionality present in RL-TCPnet or is there another way around it? The DHCP server here remembers which MAC addresses were previously assigned IP addresses and keep sending the same address over and over. We have no local control over the DHCP Server.
Because the ability to do so is built into the DHCP interface. I prefer to do what ever I can to help my company release quality, user friendly instruments. If I can figure out a way to do it, I will. I see no gain in pointing fingers and blaming others, even if the root problem is someone else's issue.
