OVPN Server-Client on Sierra RV50 Gateway Issues

Post by pgalarza » Thu Jul 21, 2022 7:24 pm

Hi,
I hope everything is going well over there. Here, it is a little frustrating.
I have a Sierra RV50 Gateway with OVPN client capabilities. Although it's fundamental, it can't allow uploading configuration from file. I was able to match my Softhether OVPN server settings and I have a steady tunnel connection established. I can ping the server side from the Sierra RV50 Gateway attached devices to all the Lan networks associated with the Virtual Hub and bridge. However, I can't ping or access any associated network of the Sierra RV50 Gateway. I searched the Sierra forum and found the following post below the lines.

According to the post, the issue resides in the server, perhaps, due to the basics of this Sierra RV50 Gateway OVPN-Client configuration.
It's there a way to give specific routing table instructions to the Client-Username from the Softethere OVPN-Server? Obviously, I can't do it from any configuration file since that option doesn't exist on the Client Gateway.

I did try to push from the Virtual Hub/Secure NAT/Virtual DHCP/Static routing table without any results.

Any help will be greatly appreciated.

Thank you.

Best regards,

PepeG

hello!

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.
Thank You!
regards,
Richard

Hi ******,

I follow the link below to config OpenVPN server and successfully ping from both side.
It seems that it’s about your server configuration. Please make sure the following steps are correct:

In config file at directory \OpenVPN\config\server.ovpn, 2 lines should be added
client-config-dir ccd
route 192.168.13.0 255.255.255.0
At \OpenVPN\config\ccd, create file with name “client” and add route to the file:
iroute 192.168.13.0 255.255.255.0
Note that: “client” is the name of Common Name at the steps that you generate certificates & keys for your gateway device, so you need to change the name accordingly.
3. Restart the tunnel.

Thanks,

If your question is answered, please help to mark Solution

Try l2.ovpn config, pick a test host on "the Lan networks associated with the Virtual Hub" and set a route on it to the "network of the Sierra RV50 Gateway".

If the host still can not ping the RV50 network, probably it never will.

Thank you for your insight. The RV50 Gateway doesn't accept configuration from a file (there is not an option for it, therefore, it has to manually be configured). :(

Attached are some pictures of the server and gateway UI

So you can't manually set L2/tap on RV50 and SoftEther has no L3/tun "iroute" equivalent. Why not simply run OpenVPN server?

If you need SoftEther's features, then you could run both VPN servers on the same system to complement each other and solve the RV50 dilemma this way.
