[En-Nut-Discussion] Use DHCP to configure ethernut IPaddr without renewal of IPaddr?

I have an application where my ethernut board communicates 24/7 each 300ms
with a server and the communication can't be interrupted.

Until now i been using fixed ipadress on each ethernut client but i need to
go over to dhcp instead. 
But then i have problems with ip renewal after 24h and then the
communication drops for a while.

Whats the best way to keep my ethernut from renewing its dhcp configured
ipadress?
I see that i can use DHCP_DEFAULT_LEASE to set leasetime but i need an
infinit leasetime.

Is there any other way to fix this then edit the dhcp.c source and remove
the renewal features?

Regards/Erik
