Using a Hitron (on VM service) in modem only mode but it's on a different subnet from the 2865 LAN1 so been trying to find a config to be able to access its admin page. Normal LAN1 subnet is 192.168.15.0/24, and Hitron admin page is 192.168.0.1. Looking for simple way to do this with NAT/static routing - is it possible?
