Hello,

I've a primary Modem/Router from my ISP.
I've plugged a TP-LINK Wireless Router TL-WR841ND, on the ISP Router, with a ethernet cable from LAN port (ISP Router) to WAN port (TL-WR841ND).
Both routers run correctly.

The primary Router (ISP) has the VLAN A (192.168.1.0), and the secondary Router (TL-WR841ND) has its own VLAN, the VLAN B (192.168.2.0).
I would like that devices from VLAN B can not see (and be able to access to) the devices from VLAN A.

Can I forbidden VLAN B to see VLAN A (or a range of VLAN A)?
Is it possible to set that from the TL-WR841ND (VLAN B)?
Could you help me to do it?

Thanks,
Chris
