VD,
I am very green to Ebox, but I run into the same problem you are experencing. My Fix:
Once you get logged into server console do:'sudo ifconfig' you should see eth0 running with an dhcp address assigned by your dhcp server. next:
do an ,,,' sudo ifconfig eth1 192.168.0.10 netmask 255.255.255.0 '
this sets the ip of your 'other' nic ( eth1 ).
now plug a cat5 wire from a laptop or dekstop ethernet port into the opposite nic port on the ebox that you previously was plugged into,
(You will need to temporarily static iP address into the laptop of 192.168.0.100)
You will be able to get to the WEB UI from eth1 at https://192.168.0.10
Once you are logged into the WEB UI make sure you set BOTH of the nics parameters and save changes!
Sidenote: The way I found this out I could not do an nmap of the Ebox ip address of ETH0.
So,,I knew I would not be able to access the ebox from what is ultimately the "public interface".
Hope this helps.
Take Care,
Barry
