Additional BOOTP/DHCP Options - documentation?
- 
 I have about 80 Polycom sip phones that connects to a ftp server on lan interface, to write logs, check for new configs/firmware etc. I could specify the ftp address manually, but thats inconvenient when a phone is replaced. So I want to distribute the ftp server location with the dhcp server (yes, I use pfsense DHCP server for the Polycom's). This is what the "Additional BOOTP/DHCP Options" are for, right? Unfortunately I can not find any guidelines on what to put in the fields "Number", "Type" and "Value". Can anyone enlighten me?

 Google is wonderful machine with it you can solve lot of questions ;)

 And how does that explain how to fill out the fields? Maybe the "Number" field…

 Was messing with the dhcp options and found the following; Added 1 option 6 entry. This entry appears to override the other dns servers entered in "DNS Servers" cause an entry here cancels out anything you put there. Anyway, want to list 3 dns servers, but entering 3 entries as option 6 I only get to see the last dns server entered. If I enter several on the same line, pfsense give me an error. Guess I need to know how to delimit one entry from the other. , and ; don't seem to work….
