i do put IP in this field (192.168.0.254) in fact, but this doesnt work.
i'm looking for a reason why it desnt work.. i've just setup:
#define IPCONFIG_DEBUG
in linux/net/ipv4/ipconfig.c, and this is what i get at boottime:

DHCP: Get message type 2
DHCP: Offered address 192.168.0.237 by server 192.168.0.254
DHCP/BOOTP: Got extension 53: 02
DHCP/BOOTP: Got extension 54: c0 a8 00 fe
DHCP/BOOTP: Got extension 51: 00 01 19 40
DHCP/BOOTP: Got extension 1: ff ff ff 00
DHCP/BOOTP: Got extension 3: c0 a8 00 fe

DHCP/BOOTP: Got extension 12: 63 6c 69 65 6e 74 46 53 42 2d 32 33

DHCP/BOOTP: Got extension 15: 66 73 62 2e 6e 65 74
DHCP/BOOTP: Got extension 40: 46 53 42 6e 69 73

Extension 6 is the nameserver (see config.c for more details) and it is
set as you can see. that is strange....
i'm looking for more hints. hope this will help.
