Solution Verified - Updated -

Issue

  • A DHCP client can't get a correct router address from dnsmasq.
  • Here is dnsmasq.conf.
log-dhcp
dhcp-range=192.168.201.50,192.168.201.100,12h
dhcp-option=tag:eth0,option:router,192.168.201.254
  • Here is an excerpt from /var/log/messages when client's NIC is started.
Nov 30 12:32:00 rhel-server dnsmasq-dhcp[1957]: 3713354755 sent size:  4 option:  3:router  192.168.201.101
  • "192.168.201.101" which is provided as router address is not a correct router address, but dnsmasq server address. "192.168.201.254" should be provided to the client as router address.

Environment

  • Red Hat Enterprise Linux 6.2
