    I can get DHCP on LAN to work, assign static IP:s on LAN, forwarding, but I just can’t receive any IP address from my ISP:s DHCP using ZeroShell!!

    EDIT: I tried to let it run for 3 hours clicking refresh but nothing happened automatically and the lease was ready to pass to another MAC address.

    could this not be done from a ssh shell ifconfig ETH?? down



    Now you have me thinking. IF the wan is dynamic ( dyndns is active) the script to reset the ip needs to be run. This as i understand it only happens at re/boot. mmm just thinking in type
