Just had a question regarding an external DHCP server for a UC 540. I have added the "IP helper-address" command to "Interface BVI 1". Everything works ok, my computers get a dhcp address but as soon as I try pinging from CUE out to the internet, I get no reply. Now, if I add the "IP NAT OUTSIDE" command to the BVI 1 interface, CUE is able to ping outwards but I cannot access the CUE through web browser. Is there any way to configre this so that CUE is able to ping out to the internet (need this for SMTP message notification) and DHCP addresses for computers come from an external server while the Phones get their IP address from the UC540 system?
It almost seems like you can only have one or the other? Also, I will be programming through CLI.
