I have configured some DHCP fixed IP assignments to several equipments at home (NAS, printer, laptops, etc.). Now I need to replace a mac address to one of this assignment (equipment replaced with a new one) but cannot do it. When I do try to replace the mac address I get this error:
There were errors in saving this configuration:
I have done in the past where I did want to use the same ip for a new device and always worked. I have also tried to delete the assignment and create again but does not work as well. I do click on X and assignment disappears but once I do save the configuration I still see it there (although dashboard says changes saved on the green pop up).
Did you try removing the existing assignment, saving, refreshing the page, and then adding the new one? Did you get that same error result?
I've also ran into interesting browser issues from time to time and have been able to use another browser when it wouldn't allow me to change configurations.
Yes, exactly those steps. Tried to remove, save, reload the page and they were back there after page reload. I have also tried to logout/login.
Actually haven't tried another browser. This makes sense as the error provided was something like "you cannot use the same mac on another ip address" or "this mac cannot be assigned to another ip address as it has been already assigned". It was not saying exactly this but more or less this was the meaning. Maybe it's a browser cache issue.
I will try with Chrome or FF later. I do normally use Safari.
Try this extreme step.
Unplug everything from the LAN side, then power cycle the MX. Now its dynamic DHCP table will be empty. try re-assigning the fixed IP address and then plug everything back into the LAN.
I can do it but don't this it will fix what I am experiencing. Basically I have several assignments and cannot even remove theme. For example I am trying to remove some of the assignments clicking on the X close to them (when those devices are off) and save. After save is done the assignments reappear again in the list.
I cannot reset the configuration as I have a lot of stuff (including firewall port forwarding rules). This is very annoying. I remember that I have changed DHCP assignments in the past when replacing devices but now does not work.
I will open a case!
Have you heard anything about this issue? I currently have 2 networks experiencing the same issue, with the exception that I'm not trying to replace a client but add a new one.
Do IPs assigned to a MAC in one network stay on that MAC in another network within the same organization???
