How to View FRITZ!Box Networks with NethSecurity VPN on Different Networks

Support

Hi everyone, I’m new!
(Sorry, I’m using a translator)
I’m using NethSecurity 8.7.2. The networks are as follows:

NethSecurity LAN (Green): 192.168.1.1
FritzBox WAN (Red): 192.168.1.194
FritzBox LAN: 192.168.77.0/24
VPN Server: 192.168.17.0/24

I left LAN management to the FRITZ!Box 5690 Pro, to which all the devices are connected. When connecting to the firewall with an OpenVPN client from a Windows 11 PC, I can’t reach the FRITZ!Box network 192.168.77.0/24. I only see the network 192.168.1.0/24. I tried setting up:
-Static routes on NethSecurity
-NAT/Masquerade
-Push route on OpenVPN

but nothing works. Any ideas or suggestions? Thanks!

Where is the NethSecurity WAN (Red)?

This is the IP that is assigned to the FRITZ!Box, thanks

AFAIK Red and green on the same subnet (192.168.1.0/24) is an hefty ingredient for a not-working network recipe.

You should use a switch for connecting all your devices to NethSecurity on 192.168.1.0/24 and a red adapter on NethSecurity should be configured in 192.168.77.0/24 network.
And only that connected between NethSecurity and your fritzbox.
You’ll need to disable the wifi on your Fritzbox and buy some other AP to deliver wireless access to NethSec Green (or blue) Network.
