I need to change the netmask pushed by DHCP on my GL-AR750s. It pushes a 24-bit netmask (255.255.255.0). I need it to push a 16-bit netmask (255.255.0.0).
I’m doing this because I want my DHCP clients to send all 192.168.. traffic to my GL-AR750s, and my clients run a VPN which grabs all non-local traffic (where “local” is defined by the netmask).
Where/how do I configure the netmask pushed by DHCP?
