I think you will find the route add command is in the Linux section of
the README file. For Solaris and OpenSolaris no such command is
required.

Suggest you look at the /var/adm/messages file to see any errors from
dhcpd. You may need to add an empty declaration for bnx1.

Oh and I just saw you have version 4.1.0. My experience with dhcpd on
Solaris 10 is that you need 4.1.1b1 or newer to get around a bug in the
network layer. This probably applies to OpenSolaris as well.

If you need to build from source, the defaults are all ok on Solaris at
least.
