Asus RT AC68U OpenVPN Server and Client

[isprewo]

Hello!
I´ve Merlin 380.65_4 installed on my RT AC68U. I´m using it as OpenVPN Server and Client. Both Tunnels are working great. I´ve only one Problem. When i connect my devices to the OPEN VPN Server i can´t access the Network which is connected with the Open VPN Client function to my Second Location.
I´m not sure but i think i have a routing problem from the VPN Server Subnet to the VPN Client Subnet.

Config:
Local Subnet: 192.168.0.x/24
VPN Server Subnet: 10.8.0.x/24
VPN Client Subnet: 10.1.8.x /24
VPN Server and VPN Client are using different UDP Ports!

On the VPN Server which i connect with my Asus Open VPN Client i see the following error in the log

MULTI: bad source address from client [10.10.2.2], packet dropped
Maybe it can also be a Problem from the VPN Server which i connect with my Asus Router.


Any ideas?


Thanks in advance

Bye

You can refer to a screen print of my OpenVPN server configurations in post 56 to see if that helps.

@Martineau has a great script to provide that works like a charm. It makes it so you can see both subnets from either server side or client side. See starting here the thread that can help you https://www.snbforums.com/threads/o...e-to-site-connection.24268/page-5#post-313244

For the remote subnet you are listing you aren't telling what the range is in that subnet. The remote local subnet shouldn't be 192.168.0 it needs to be a different from your local subnet on the server side.

Hello

Thanks for your answers.
I think the Subnets are different.

Local Subnet: 192.168.0.x
My Asus Router connects a VPN Net with the subnet 10.1.8.x and the VPN Net which has the Router himself created is 10.8.0.x.

So i think these are 3 differnet scopes!

@Xentrk This config is in my opinion not secure enough! I will try this config this weekend but as i sayed i think this is a little bit unsecure so therefore it isn´t a solution for me.
My Config is working great only the routing between the 2 VPN scopes is not working.

@Wingsfan87
Thanks for the link i hope i have time these weekend to read the posts carefully maybe i find there the right solution for me.
