OpenVPN Server to OpenVPN client with 2 Routers and 2 LAN

[Job314]

Hello to all!

I describe my situation that is making me lose my mind:

I have 2 LAN and 2 routers RT-N66u and RT-N16.
My goal is to be able to access HDDs connected to the routers and also to access shares of both LAN PCs.

RT-N66U (with OpenVPN server) - 3.0.0.4.270.26 (Merlin build)
IP: 131.114.0.0
Mask: 255.255.255.0
Gateway: 131.114.0.1
OpenVPN: 10.8.0.1

RT-N16 (with OpenVPN Client) - Tomato Version 1.28 by shibby
IP: 192.168.0.0
Mask: 255.255.255.0
Gateway: 192.168.0.1
OpenVPN: 10.8.0.6

From Client I can ping and browse shares of Server
ViceVersa impossible

If i change and set RT-N16 OpenVPN server and RT-N66U OpenVPN Client.... is the same problem:
from client to server, no problem, i can ping also the PC behind the router.
From Server to Client impossible....
In Server i set "allow Client to Client" but the problem persist.
I tried disable firewalls on each router but without results.
I tried install DD-WRT on RT-N16 with the same problem.

I tried to set static routes but But I do not know how to set them, and I do not know if that's the problem.

It seems impossible that there is a way to do
Can you help me? I'm desperate :-(

Thanks
Job

Edit: Only now I realized that Merlin has released a new firmware that supports RT-N16

I could also do this test but I think that the problem remains.
Since I did not even changing firmware changes, I fear that there is something to be set do not know.

other tests done:
Now to test and for ease of testing I set the RT-N16 as openvpn server and the RT-N66U as a client.

I have opened the door manually 3140 on the firewall of the RT-N66U with the commands:
iptables-A INPUT-i any -p udp - dport 3140 -j ACCEPT
iptables-A OUTPUT-o any -p udp - dport 3140 -j ACCEPT

Based on the routing table of the client (which works perfectly) I added a route manually on the server with the command:
route add -net 131.114.0.0 netmask 255.255.255.0 gw 10.8.0.2 tun21

No work

I also tried manually stopping the firewall of both routers ("service stop_firewall" on RT-N66U and "service firewall stop" on RT-N16).

I am attaching some pictures of openVPN server, client, and routes of both routers.

The absurd thing is that from client (RT-N66U) to the server (rt-n16) everything works perfectly, and vice versa nothing works. From the server (rt-n16) I can only ping the ip generated by the VPN server (10.8.0.6) that corresponds to the client (RT-N66U) !!

Specific connected to the WAN RT-N66U I have another router that provides internet connection (192.168.205.1), but he has all the doors open (already checked in every possible way) and the firewall off.
Idem for RT-N16 (the router that provide internet connection is 192.168.1.1 with all doors opened and firewall off)


Please help me ...

Difficult question I’d advice you to get in touch with your VPN service provider. They will be the very right resource to get you out from it and also i would suggest that you visit a review webstie like bestvpnservice.com
