problems with dhcp.
i have a cisco 1811 router that i connect to the internet through a cablemodem. I use dhcp client on the wan port to get my ip addr. the problem is that when I reload the router I can?t get a IP address for my Ethernet port. I?ve tried many combinations of resetting the modem and changing Ethernet port states (shutting down, additional client params (client-id, hostname), renewing and releasing dhcp, stopping dhcp service, no ip address and ip address dhcp, allowing any ip and udp traffic. If I erase the configuration files and reload I can get a ip, and then if I (conf)#no ip address and (conf)#ip address dhcp I can get a different IP.
If I try to renew dhcp after a reload I get error : not in bound state.
If I don?t have the Ethernet port up and connected after I erase and reload then I will not get a ip address (this seems to be the only time I can get a address).
And some debug output:
