K2DLS:

Supply the following if possible:

  • Device problem occurs on WRT1900AC
  • Software versions: LEDE Reboot 17.01.4 r3560-79f57e422d / LuCI lede-17.01 branch (git-17.290.79498-d3f0685)
  • Steps to reproduce

I was attempting to run odhcpd + unbound as documented here:

https://github.com/openwrt/packages/blob/master/net/unbound/files/README.md#unbound-and-odhcpd

While odhcpd did serve up IPv4 addresses, it ignored the start and limit parameters in the config dhcp section of /etc/config/dhcp. Addresses outside of the desired scope were assigned to clients.

Can you provide more detailed info like the dhcp config being used; which address has been leased to a client not belonging to the dhcp start/limit parameters ?

Works for me using following config :

dhcp.lan=dhcp
dhcp.lan.interface='lan'
dhcp.lan.start='100'
dhcp.lan.leasetime='12h'
dhcp.lan.dhcpv6='server'
dhcp.lan.ra='server'
dhcp.lan.dhcpv4='server'
dhcp.lan.limit='1'
dhcp.odhcpd=odhcpd
dhcp.odhcpd.leasefile='/tmp/hosts/odhcpd'
dhcp.odhcpd.leasetrigger='/usr/sbin/odhcpd-update'
dhcp.odhcpd.loglevel='7'
dhcp.odhcpd.maindhcp='1'

Client is assigned 192.168.1.100 which is within the configured range :
