Because the Ewon is a router, the WAN and LAN must be different subnets. Assuming a subnet mask of 255.255.255.0 or greater size network (which is probably safe to assume on a factory network), you can not use 10.0.0.x on the LAN and WAN at the same time.
Thanks, I’ll try to remember this time.
Can you tell me from the s/n, what the MAC address is?
