Access to VPN Server over the internet, while Open VPN client is active

[Wingsfan87]

Thanks a lot for your explanation. I will test your setup .
May I ask some questions before I try:
1. Why it is important to disable the Asus firewall? wouldn't it decrease the overall security? is there a possibility to avoid that? So you can access the VPN router from the Fritz side. Not really but its on the inside of your internal network. Yes its not required but it's something I do on my end. You can set IP table rules etc via script but that is more advanced.

2. the clients on the asus server will get an ip 192.168.1.x or 192.168.50.x? 192.168.51.x if you changed the ASUS LAN

3. what is exactly static routing and why it is important ? sorry I am a total newbie.... Static routes tells the traffic where to go between 2 subnets. Its a must if you have more than one router on the network. When you're on one your networks requests wont be able to route to the proper router and subnet. This tells the traffic where to go. If you don't have it it wont work.

4. will the fritzbox be accessible via 192.168.50.1 any more, if I make a static routing?(point 1.5.) Yes you would be able to access the Fritz side from Asus.

5. why I have to change the subnet of the fritzbox from 192.168.0.1 to another e.g. your proposed 192.168.50.1? What is the sense behind that action? I always change from default so there is no interference when I am traveling for any remote subnet being the same or problems with other devices that have the same defaults. Just a little piece of mind and ease to keep things little more secured etc.

Thanks a lot for your support

Sorry for my late reply, up to now, my test were not successful.

Only to be sure regarding the right configuration of my static route:

My fritzbox has the ip 192.168.50.1, the Wan Port of my Asus has the IP 192.168.50.180

The asus router itself acts as DHCP server with 192.168.51.1

All clients get an Ip address with 192.168.51.X

In my fritzbox a field static ip4 route has three fields:
- IPv4 network :
- Subnet mask:
- Gateway:

What numbers should I put into?
