Setup: Server (Oxygen VDSL router) VPN IP 10.8.2.0 / LAN IP 10.10.11.1 Client1 windows 10 PC, VPN IP (Auto -DHCP) / LAN IP 192.168.10.10, Gateway TP LINK TD 8980 IP 192.168.10.1 Client2 windows 7 PC, VPN IP (Auto-DHCP) / LAN IP 192.168.1.2, Gateway TP Link TD 8980, IP 192.168.1.1 Client3 windows 10 PC, VPN IP (AUto-DHCP) / LAN IP 192.168.20.145, gateway TP Link TD 8980. IP 192.168.20.254 The scripts for connection are automatically generated from Oxygen gateway. client1 subnet, client2 subnet and the devices behind the Server can talk to each other with no restrictions But client 3 devices cannot. The firewall is off on all PCs The strange is that if I deactivate the VPN Service and reactivate it again, I get connectivity for about 10 seconds. I can ping device 10.10.11.1 from the client3 PC (192.168.20.145). After these 10 seconds I lose it. Can anybody point me to something that I have missed? All static routes are correct

This is an example of tracing the ip of aVPN Server's side device from the site 192.168.20.30 Cannot understand what is going on Tracing route to 10.10.11.12 over a maximum of 30 hops 1 1 ms 2 ms 1 ms 192.168.20.254 2 2 ms 1 ms 1 ms LBase [192.168.20.36] 3 * * * Request timed out. 4 * * * Request timed out. 5 * 2788 ms * 10.10.11.12 6 * * * Request timed out. 7 * * * Request timed out. 8 * * * Request timed out. 9 * * * Request timed out. 10 3795 ms * * 10.10.11.12 11 * * * Request timed out. 12 * * 3786 ms 10.10.11.12 Trace complete.

Logs of the client do not show anything spaecial. I 'll check the log files on the server. The problem is that VPN runs as a servi e on this gateway and I cannot access the file system. It offers as a choice to save the log files on USB stck. I will try this and see if I can access the log file

I can see that it is a very common problem to many users, but I cannot find any solution This is the client configuration and the log of the client side [oconf=client Config] client remote
