Access WAN modem behind switch

[Alexander Scherdo]

Hi,

is it possible to have the WAN modem connected to a switch which is connected to Asus router (RT-AC87U)?
Modem<->switch<->Router
Other devices connected to the switch should be able to connect to the internet also.

The cable modem has a static IP of 192.168.100.1 my routers network is 192.168.0.x (255.255.255.0).

If this is possible, how should the router setup be for WAN?

Best regards
Alex

The easiest way to do this is to connect your WAN Modem in bridge mode (as far as I guess it should be already in that mode because of the static IP you wrote, my ISP's router gets that IP when I turn on bridge mode on it) and connect one cable to the WAN port (blue) of the RT-AC87U. Then connect another cable from the switch (yellow ports) of the RT-AC87U to the switch and then all the devices you connect to the switch will work

maybe I should state the reason why I ask. I like to have the router in another place than my modem and a Raspberry PI. SO ONe wire to modem &RPI from router.

Your devices (Raspberry Pi?) connected to the switch would not benefit from the extra protection of being behind the router's firewall.

Ah true you are right. Then it is not an option. Thank you.

Good man! As Merlin says,"Without a firewall = everything running ..... would be open to the WAN, ... "
