Hello,

i set up a RUT240 with new Firmware RUT2_R_00.07.01 as an OpenVPN Client (tun) to the main company site. The connection gets established, i can also see this in the Sophos Firewall. the target is to connect a VOIP telephone to the comapny Telephone system. But the telephone is not able to register itself in the seystem.
With CLI on the router i can ping several IP's inside the company network. So the tunnel is working i guess. Unfortunately, from a computer sitting on the lan-side of the RUT, it is  not possible to ping anything inside the company network. What do i need to set-up in the firewall of the RUT240 to get these networks together?

Hi,

I recommend going through this link for Openvpn configuration "https://wiki.teltonika-networks.com/view/OpenVPN_configuration_examples", Ensure the Firewall zone mapping for VPN, LAN are set as provided in the link. Also, for the voip, conntrack feature needs to be utilized on the RUT firewall.
