Zyxel DX3101 set more than 32 ip/mac rules

jumbo125

Hello everyone

I use the Zyxel router, which my provider (A1) provides. 
I'm actually happy with it, the only thing that bothers me is the limited IP/Mac address assignment

I can make a maximum of 32 assignments. The router then writes “Max. number of rules reached”.
Therefore, I now always have to think about which device I can most easily do without.

Is there another solution for this?
Thank you
