I have an RV50 and i have set up the OpenVPN tunnel with success (thanks to others in this forum, without their help i would not succeed). The WAN is a 3G connection, there is a wired device connected to the LAN port of the RV50. I am able to ping the both ends of the tunnel. I would like to route traffic over the tunnel to reach the host behind the RV50 (the wired device). This device has its default gateway set to the RV50s internal (LAN) IP (192.168.13.31)
The problem is: i can not reach the device form the OpenVPN server side. I can reach the server from the device, but not vice versa. The server has a route set up to send packets desired for 192.168.13.0/24 (RV50 LAN network), the packets enter the tunnel, but there is no response. The RV50 simply does not forward them to its LAN interface. I had FW 4.9.3 installed, i updated it to 4.9.13, but it does the same. I also tried NAT, but it does not NAT packets coming from the tunnel… Also it does not route traffic coming from the LAN into the tunnel when NAT is diabled in the OpenVPN settings. Is there an option i am missing? To me it seems, that packets coming from the tunnel gets dropped by some rule. I factory reseted the RV50, all port filtering is also disabled. I even tried to set the DMZ IP to the devices IP address, but the same happens. If You have any idea or suggestion, please share it.
