I have successfully setup an admin/management VLAN on my OpenWrt router with firewall zone forwarding to the LAN interface so that for example, a computer connected to the admin VLAN can connect the LAN resources etc. I have also setup access to the admin VLAN from certain LAN devices through the use of traffic rules and specific MAC addresses.
I'm now trying to connect to a HP Wireless Printer that is on the LAN from the admin VLAN. Unfortunately the
HP Smart app doesn't support different subnets hence I can't see the printer in the app. However, there doesn’t seem to be any problem with being able to access the printer’s admin GUI webpage and ping the IP address.
Is there anyway of being able to connect to the printer from a device on a different subnet? Will static routes help at all, although I have never used static routes nor would I know where to start, however, I do understand the IPv4 protocol fairly well.
