Also, if router comes in new, usually it is set up to boot with flashfig enabled. That might help you a bit.
Hmm, this could be something I can use. I see that you need a windows computer with Netinstall/Flashfig installed. I don't use anything that is windows based.
My current setup is that I have a linux server that will be on the same broadcast domain as the CPE. The CPE gets an IP-address from a DHCP server (there is a DHCP-relay in between) on the standard dhcp-client interface (ether1-gateway).
The linux server has configuration files stored for RouterOS clients. Is there a way I can make flashfig work with this setup? Or do I need to prepare the CPE before placing it at a customer's premises?
