Hi!

I want my OpenWRT devices to set a static IP if no DHCP is available in the network, or if DHCP fails for whatever reason. Is there an OpenWRT-Way of doing this?

Thanks a lot

here we go.. ( used in trunk )

config interface 'lan'
        option type 'bridge'
        option proto 'dhcp'
        option ifname 'eth0.1'

config interface 'lans'        #lan static IP
        option 'ifname' 'br-lan'
        option 'proto' 'static'
        option 'ipaddr' '172.16.211.18'
        option 'netmask' '255.255.0.0'

you may do so with wan

other way aroud i.e. 'lan' as static and alias as dhcp did NOT work for me

CAVE!   ifstatus lan will show the static address of 'lans'  until given IP form dhcp-server

To make everything working, you should specify dns and gateway too. This is config from my wr1043nd v2, ifnames are different on different devices.

vi /etc/config/network

config interface 'lan'
        option ifname 'eth1'
        option type 'bridge'
        option proto 'static'
        option ipaddr '192.168.1.1'
        option netmask '255.255.255.0'
        option ip6assign '60'

config interface 'wan'
        option ifname 'eth0'
        option proto 'static'
        option ipaddr '172.16.1.21'
        option netmask '255.255.255.0'
        option gateway '172.16.1.1'
        option dns '78.138.98.82 192.121.121.14'
