Newbie question: OpenVPN server/wifi router/cable modem arrangement

[Smpl5]

I am wanting to access my local LAN while travelling, so I purchased a Slate travel router and a Brume 2 (2500) for the server. I have a cable modem connected to an ORBI wifi router. Do I need to insert the Brume between these two devices (i.e., Cable modem to Brume WAN and Brume LAN to Orbi WAN) or is it sufficient to connect the Brume WAN port to the Orbi LAN? If the latter, is it necessary to connect anything to the Brume LAN port?

I have gone through the tutorials and I think I understand what I have to do configuration-wise, but I am uncertain as to the equipment arrangement.

Thanks in advance

Hi

As you are new to router/VPN server configuration, we recommend connecting the Brume 2 between your ISP modem and the Orbi.

Afterwards:

1. Configure port forwarding or DMZ on your ISP modem for Brume 2. This is for opening the OpenVPN server port to public netowrk.
2. Set the Orbi to AP mode to avoid double NAT and VPN routing issues.

For information on setting up the OpenVPN server on Brume 2, please refer to Set up OpenVPN server - GL.iNet Router Docs 4.
