Why don't I get my reserved Ip address

Hi All

I’m trying to setup DHCP reservations. Here’s the relevant sections of my config (I hope)

/ip pool
add name=default-dhcp ranges=192.168.88.10-192.168.88.254
add name=DHCP-Server ranges=10.0.0.100-10.0.0.150
/ip dhcp-server
add address-pool=DHCP-Server disabled=no interface=bridge-local lease-time=1d
name=DHCP-Server

set ddns-enabled=yes
/ip dhcp-client
add comment=“default configuration” dhcp-options=hostname,clientid disabled=
no interface=ether1-gateway
/ip dhcp-server lease
add address=10.10.0.1 mac-address=80:00:0B:71:33:74 server=DHCP-Server
/ip dhcp-server network
add address=10.0.0.0/8 comment=DHCP-Server-Network dns-server=10.0.0.1
gateway=10.0.0.1

I’m expecting my PC to get the IP address in red, but keep getting 10.0.0.115. I tried IP config /renew. Tried disabling and re-enabling the adapter.

Attached is a screenshot of the DHCP Server dialog. Why does it say "waiting " for the static assignment?

Before doing release/renew, try deleting the .115 lease. If that doesn’t help, then use wireshark on your PC, set the filter to: “port 67” (without the quotes)

Do a release and renew

You should see these packets:

  • Your PC alerts the DHCP server that it’s releasing (which would normally remove the lease)
  • Your PC does an autodiscover and requests the same IP as it had before
  • Mikrotik should reply with an offer, it should offer an IP (the static one).
  • Your PC then requests that IP, and the server Acknowledges.

**Note: The packet sniffer in Mikrotik doesn’t seem to capture packets the Mikrotik sends out, so it’s no good for troubleshooting DHCP.
