Hi!
I have been struggling with this very weird behaviour of DHCPd server on
OpenBSD 4.4 for some low-price routers such as EUSSO, Edimax, D-Link.
DHCPd server log output seems OK (see below), but still those low-price
routers get only IP address and mask, but no gateway IP adress, nor DNS
IP configuration from DHCPd server. Meanwhile there is no problems with
getting (FULL) IP configuration for MikroTik, OvisLink, Ubiquiti routers
and even MS Windows DHCP client from OpenBSD 4.4 DHCPd server! :)
I have used the same configuration on OpenBSD 4.2 and there is no
problem, but cannot get it work on OpenBSD 4.4. Why is that? What could
have changed in DHCPd server since 4.2 relase?
Some of mine OpenBSD 4.4 router information below.
Thank you for your input,
Janis.
