Question

Hello.. I am trying to bridge a Mikrotik CCR (OpenVPN server) and RUTX12 (OpenVPN client). However, both the Mikrotik CCR and RUTX12 must have the same LAN subnet (e.g. 192.168.20.0/24) and devices behind the CCR must ping devices behind the RUTX12 and vice-versa. Is this possible? Can someone PLEASE guide me how to implement this type of configuration? There is a howto available here - https://wiki.teltonika-networks.com/wikibase/index.php?title=Template:Netoworking_rutx_configuration_example_mikrotik_openvpn&veaction=edit&section=T-1&mobileaction=toggle_view_mobile - but this supposes different LAN subnets (192.168.88.0/24 for Mikrotik and 192.168.1.0/24 for the Teltonika device).

Thanks for all help in advance!

Hello,

To bridge two interfaces, the devices have to operate on MAC layer. This can be achieved by using TAP mode in OpenVPN configuration. Please check the following configuration example: https://wiki.teltonika-networks.com/view/Connecting_two_same_subnet_office_networks_using_OpenVPN_bridge_(TAP)_on_RUTX.
