Activated NAT on ETH01 then, removed all IP on ETH01 My lan connection is on ETH00 and I have DHCP server on it. the IP is 192.168.0.1 My cable modem has a web interface at 192.168.100.1 interface is connected on ETH01 But it dowsn’t work, and ZeroShell doesn’t get IP address from the cable modem. Can someone explain me what step is needed to connected to cable modem to ETH01 and my LAN on ETH00?

I try to “renew” with no sucess.

In log I found this line: No dhcpoffers received. February 11, 2012 at 8:52 pm #52196 redfiveParticipant so, you haven’t any rules in input chain and the default policy is accept ??
