DHCP options can't be removed
-
I think the WebIF part for DHCP-options on the DHCP-server page can be improved.
I wanted to use DHCP-options for giving other DNS-servers to the DHCP-clients. I incremented the option# once. I now had to look up which option# is for DNS-servers.
I then suddenly saw the special section where I could give alternate DNS-servers.
I didn't have to use the "Options" part at all.
I entered the 2 DNS-servers in the designated section and pressed save.
It worked!Then I noticed that the entry for special DHCP-options was open. I wanted to get rid of it, but I didn't see a way to do this. I thought I could decrement it one step further, so there was no option number visible, but this wasn't possible either...
Because it wasn't possible to remove the entry I falsely thought it didn't have any effect because I didn't assign a value.
A few days later people started to complain about not reaching any websites. It turned out these were given a 255.0.0.0 netmask instead of 255.255.255.0 one.
This means they couldn't reach any Internet-site within the 192.0.0.0/8 network.I found no other way of removing the entry than downloading the configuration XML, editing that entry out of the configuration and reloading it.
I will never make this same mistake again, so I don't need it fixed.
I still think it should be fixed as there should always be a way to remove an entry with the webif if you also created it with the webif.Even if there's a way to do it with the webIF, I wasn't able to find it intuitively...
