Anyone know how I can add DHCP options into the Draytek as im using it for DHCP.

Thanks

You can from the telnet/ssh interface. The command is:

srv dhcp tftp <server>

You can then do srv dhcp tftp ? to read what it is set to.

We have the 'do' instructions but there appears to be no 'undo'?

Is there a special string or control code to erase so as not to issue a DHCP tftp server please?

Have tried a trailing 'clr' that serves to do something in another 'srv dhcp' sub-command. All strings tried simply get entered as the reply string. A defaulted router seems to have 'null'.

The closest we've managed is:

srv dhcp tftp " "
but we are not confident this is the same as the default state.

Background:
We've encountered a situation where we only wish to temporarily use this functon and wish to cleanly remove it without factory resetting the 2820 (3.3.4.1_232201 UK coded product).

Apologies if this has been enhanced already (newer/forthcoming firmware).
